'''343 Guilty Spark''' is the sixth [[campaign]] level in ''[[Halo: Combat Evolved]]''. It takes place at the [[Alpha Halo]] [[Flood Containment Facility]]. This is the first level you ever encounter the [[Flood]] in the Halo trilogy. It is also the first level where you will use the [[Shotgun]], the last level where you will be aided by [[Marines]] which are at the end of the level, the only level where you fight [[Covenant]] enemies without fighting the [[Elites]], and the first time in the Trilogy where [[Sentinels]] appear.
{{Article quote|Creep through a swamp to meet the only enemy the Covenant fear.}}
The first chapter of the level is set in a rain forest and the second chapter, "The Flood" is set in the Alpha Halo Containment Facility and the third chapter is outside the Containment Facility.

In the swamps near a [[Flood containment facility]] on the surface of Installation 04, John-117 is dropped from ''[[Echo 419]]'' to search for [[Captain (Navy)|Captain]] [[Jacob Keyes]] who has been out of contact for over 12 hours. Soon, the Master Chief stumbles upon a structure and ventures within it, only to find out that the Marines accompanying the Captain have been slaughtered by [[Flood|an unknown force]]. After realizing the fate of the Marines, John fights his way out to the swamp and encounters [[343 Guilty Spark|a questionable ally]].

*'''Flight Captain [[Carol Rawley]] (COM)''': "The last transmission from the Captain's dropship was from this area. That was over twelve hours ago."
 
'''''NOTE''': In the Anniversary subtitles, Rawley adds, "...and we've been unable to reestablish contact with the Captain or his team."''

*'''Rawley (COM)''': "When you locate Captain Keyes, radio in, and I'll come pick you up."


== Equipment ==
''In certain parts of the level, the player can hear a radio transmission coming from a crashed human dropship and a [[Covenant comm node|Covenant communications terminal]]. As it repeats, static pervades the transmission, and the signal fades in and out of clarity.''

''(Opening cinematic-Camera flies over a group of [[Jackal|Jackals]] and [[Grunt|Grunts]] running through a swamp, panicky and obviously in retreat. As it pans over them, you see through the fog and rain the outline of a [[Pelican|dropship]], which further materializes as the camera draws closer)''.
''John-117 quickly finds the crashed dropship sending the message. There are weapons and supplies piled nearby, but no signs of life.  An explosion in the distance throws the bodies of an Unggoy and a Kig-Yar through the air.  He heads off to investigate and finds a crashed Covenant [[Dextro Xur-pattern Spirit|Spirit]].''


'''Foehammer (O.S.):''' "The last transmission from the [[Captain Keyes|Captain]]'s dropship was from this area. That was over twelve hours ago. When you locate Captain Keyes, radio in, and I'll come pick you up."
''The Chief also encounters a small group of Unggoy and Kig-Yar, which he quickly eliminates, before crossing a log bridge. As he moves across the bridge, he sees several [[Flood combat form|shadowy figures]] running around on the top of the cliff to the right. Also, his [[motion tracker]] shows seemingly friendly units in the swamp not too far from his location, but they suddenly disappear off radar.''


{Gameplay}
''When he reaches the other side, he hears [[MA5B assault rifle|assault rifle]] fire nearby. He investigates and sees a mob of Unggoy and Kig-Yar fleeing from a large entrance. A [[M9 fragmentation grenade|frag grenade]] explosion throws a [[Mamua'uda-pattern Shade|Shade]] turret through the air. The fleeing Covenant regroup nearby and attack him out of fear.''


''(In certain parts of the level, you can hear a radio transmission coming from a crashed human [[Pelican|dropship]] and a [[Uplink Crate|Covenant communications terminal]]. As it repeats, it seems that this is some sort of distress beacon. Static pervades the transmission, and the signal fades in and out of clarity)''.
''John-117 kills the Covenant and hurries to the entrance, but finds no one there. A lift arrives for him. He takes the lift down into the depths of the structure.''


'''Unknown Pelican Dropship PILOT:''' "Dropship Victor 933-(static)-''[[UNSC Pillar of Autumn|Pillar of Autumn]]''-(static)-need assistance.

''John-117 passes through several large rooms and many smaller ones inside the structure, filled with Unggoy, Kig-Yar, empty Shade turrets, discarded weapons, and dead bodies - both Marine and Covenant. Curiously there is no sign of any [[Sangheili]], alive or dead. In some rooms, Kig-Yar and Unggoy gather at the doorways as if expecting an attack. In one room, the Chief discovers a strange green-yellow substance falling from the ceiling.''


''(An explosion is heard, and Grunt and Jackal bodies fall out of the air, followed by empty Covenant weapons)''
[[File:343GS lvl 01.jpg|thumb|300px|The Chief arrives at the ominously empty facility.]]


''(The Master Chief crosses a log bridge, and sees multiple [[Combat Form|shadowy forms]] running around on the top of the cliff to the right.)''
''As the Chief comes into an area blasted with gunfire and scorch marks, there is the sound of shattering glass. A lone Marine sits leaning against a wall, [[M6D magnum]] pointed at him. The Marine shoots at the Spartan if the Chief comes too close, while screaming at the top of his lungs the following phrases. He also fiddles around with his pistol a lot, checking to see if the magazine is full.''


''(As he reaches the other side, the things are gone. Assault Rifle fire is heard and it's coming from the entrance to an A-shaped structure. Grunts and Jackals are running away. A frag grenade explosion throws a Shade turret around.)''
'''[[Paranoid Marine]]''':


''(The Chief, thinking Marines are attacking them, hurry to the entrance, but then they once again vanish. A lift arrives for him.)''
*"Stay back! Stay back, you're not turning me into one of those things! I'll blow your brains out! Get away from me!"


''(The Chief passes through several large rooms and many smaller ones inside the structure, filled with Grunts, Jackals, empty Shade turrets, and dead bodies, both Marine and Covenant)''
*"''Gaaaaahh! Aaaaaahh!'' Don't touch me, you freaks! I won't be like you, I'll die first! Find your own hiding place, the monsters are everywhere!"

''The Master Chief approaches the door cautiously. There is a noise behind him; he turns around, gun ready to shoot anything. After a moment, he turns back to the door, listens for any movement inside, then making sure it was clear, he places his gun on his shoulder, and opens the door. When it opens, a dead Marine falls into his arms. The Chief advances a few paces, places the body on the floor gently, and sweeps his [[MA5B Individual Combat Weapon System|Assault Rifle]] about the room. He notices a helmet lying on the floor, and, crouching, moves swiftly towards it. Once he's there, he surveys the room one more time, places his [[MA5B Individual Combat Weapon System|rifle]] on the floor, and picks up the helmet. The name JENKINS is stamped across it. There is a large, jagged hole punched through the top of it. The Master Chief shakes his head, and removes a [[Recorder Chip]] from inside the [[Helmet Recorder]], near the HUD, and inserts the chip into a socket in his helmet''.

''John-117 leaves him, and makes his way into the room, which is covered in dead Covenant bodies, blood, bullet holes and plasma scoring. Some areas of the floor are blackened with blasts from explosions. In some areas, small flecks of a greenish substance are found on the floor. The Chief finds a partially shattered walkway and ascends to the second floor. An assault rifle lies on the ground, pointing like an arrow towards the entrance of a room marked with ominous red Forerunner glyphs. The door appears to have been forced open. The Chief goes in, passes a dead Marine, and walks down a ramp.''

'''Private Mendoza:''' "Why do we always have to listen to this old stuff, [[Sergeant Johnson|Sarge]]?"
''John-117 approaches the door cautiously and listens for any movement inside. Just as he is about to type a command into the spoofer, there is a noise behind him. He turns around, gun ready to shoot, but sees nothing. After a moment, he turns back to the door, places his gun on his shoulder and opens the door. When it opens, the body of a Marine falls into his arms. He advances a few paces, places the body on the floor gently while making sure nobody follows him through. He sweeps his assault rifle about the room.''

Once there, he surveys the room one more time, places his rifle on the floor, and picks up the helmet. The name "JENKINS" is stamped across it. There is a large, jagged hole punched through the top of it. The Master Chief shakes his head. He then examines the helmet more closely and notices that the [[helmet recorder]], near the [[Heads-up display]], is still intact.

===The Flood===
'''{''Gameplay''}'''


==Walkthrough==
''The door John-117 came through is now locked. Three doors holding dozens of Pod infectors break open one at a time, their inhabitants attacking him.''
===Well Enough Alone===
 
This is a lot vaguer place than any level in all the rest of the Halo series, keep your calm, nothing will attack you, just keep track on your motion tracker, use your flashlight sparingly.
''The entrance breaks open. Massive amounts of infectors skitter inside, followed by unarmed Sangheili combat forms.''
 
''John-117 escapes the facility, encountering Flood forms and some Covenant infantry struggling to survive.''
 
[[File:Scrn 036.jpg|thumb|250px|John is about to be attacked by [[Pod infector]]s that broke quarantine in the containment facility.]]
 
''John-117 tries to take the elevator he entered with, but while he waits for it to come down, it suddenly falls down and crashes down to the bottom of the facility.''
 
''After some fighting, John-117 arrives at another elevator, but it goes deeper underground and Unggoy blood is seen painted on the elevator's shaft. At the bottom of the shaft, he's attacked by armed combat forms - both infected Sangheili and humans. This detour forces him to fight his way back up.''
 
''John-117 eventually sees two (three on Easy/Normal difficulty) Marines armed with [[M90 shotgun|shotguns]] and assault rifles fighting the Flood.''
 
''Although their weapons give them a distinct advantage, a single Pod infector or a single combat form attack can kill them.''
 
''If they survive, they hold their position inside the room, saying the following in random order:''
 
*"This is suicide (man)!"
 
*"I'm gone, man!"
 
*"I'm not sticking around to get killed!"
 
*"We/I can't stop them!"
 
*"Forget this!"
 
*"Later, dude!"
 
*"I've had enough of this crap!"


Walk over to the downed [[Pelican]]. Fill up with the ammo, on Easy you will always acquire a [[Shotgun]], but in Normal and higher playthroughs, Bungie has removed it so just fill up the ammo and continue. In addition, if you are not on Easy the time when you will actually get the shotgun is much later in the level.
*"I'm outta here!"


Move down the path through the big puddle. A little up ahead, you will find a couple of dead Covenant with two [[Plasma Pistol]]s and one [[Needler]]. Ignore it; it's dead empty. On the other hand, those [[Plasma Pistol]]s are fully charged. Ditch your [[MA5B Individual Combat Weapon System|Assault Rifle]] for one of them.
''John-117 reaches the final elevator and rises to an exit from the structure.''


There is a path leading up towards the ramp right up the Pelican Hill, there you would get an Active Camo, but it's practically useless unless you like to ambush some Grunts.
*'''Rawley (COM)''': "This is ''Echo 419''. Chief, is that you? I lost your signal when you disappeared inside the structure. What's going on down there? I'm tracking movement all over the place!"


Ah, the fresh scent of a fully charged directed energy weapon. Move ahead and you should see another downed covenant dropship, the [[Brilliant Gift]]. There is a small group of Grunts and Jackals (about six total). The Grunts are dumb enough to charge straight at you, so switch to your Human Pistol and pump each one a headshot or smack them in the face. The Jackals tend to stay back, so time to get that [[Plasma Pistol]] ready. Feed each one an Overcharge, and melee them dead (to save Pistol ammo).
''John-117 reaches the top where a trapped group of 10 Marines are holding out.''
Once they're gone, keep moving until you reach this sort of ramp made of a large tree root. There is a Jackal nestled in a crook on the other side, so feel free to feed him an Overcharge and a melee. Now go back for your other [[Plasma Pistol]].


Go across the tree bridge, and you should see a Shade on the other side.(When you are on the centre of the tree bridge, look to your right. You should see a large metal pipe. Jump toward it and hike up along its left side. Here, you will find one unit of Active Camo.) Keep moving, and you should see an explosion, and another group of Grunts/Jackals getting their alien asses kicked by (what I hope to be) Marines. Feel free to start unloading Overcharges on anything that moves. Once the main faction has been fried, go in and melee anything that remains. Now go back for your Assault Rifle (chill, you critics, I know what I'm doing!)
''It is obvious they used a lot of ammo to escape, and it is all stacked in a pile. Most Marines hold shotguns and assault rifles, one or two have [[Okarda'phaa-pattern plasma rifle|plasma rifles]].''


Well, if there were any Marines in the first place, they sure bugged out really quickly. Well, you need to get used to being alone. That's how it’s going to be from now on. Get on that lift and get down into this creepy structure.  
[[File:HCE 343GuiltySpark SecondSquad.jpg|thumb|250px|John-117 leads the Marine survivors to escape the Flood-infested swamp.]]


When you stop, switch to your Assault Rifle and get ready to have some fun. In the little antechamber, there is another squad of Grunts/Jackals (where are the Elites?). Newbies prefer to toss a frag grenade among them, but I like to blow away the nearest Grunt to get their attention, then move through the other end of the antechamber and melee the first enemy in front of you, and repeat/rinse until their all dead. Serious fun. Or if you want to hear them scream toss a frag grenade in there.
*'''[[Chips Dubbo]]''': "Sir! Thank God you're here. We've been lost out here for hours. After we lost contact with the rest of the mission, we, we headed for the RV point, and then these-these....these ''things''...they ambushed us. We've gotta get out of here!"


In the next room, grab a [[Plasma Pistol]] and send some Overcharges over to the Covenant on the floor. Once most of them are RIPing, grab your Assault Rifle and get on the floor and beat the rest to death. Moving on to the next room, you'll see three Jackals; proceed to beat their brains out. In the next hallway, you should see a dead Jackal, a lot of Covie blood, and a small room full of mangled Covenant corpses. Obviously, this place has something that's lurking in its dark corners. Let's hope we don't run into it on a bad day. The next couple of rooms are just as creepy.
*'''Flight Captain Rawley (COM)''': "There's a large tower a few hundred meters from your current position. Find a way above the fog and foliage canopy and I can move in and pick you up."


Eventually, you'll come to a room that has seen some serious combat. Bullet holes, plasma scoring, blood, mangled bodies, flaming wreckage, complete with one scared-out-of-his-mind Marine. That poor guy obviously saw some bad things going down, and he gives me the creeps even today. I sure hate to say it, but put him out of his misery. Just go in and melee him. After that grim job, go to the other side. You should probably find a fully charged [[Plasma Rifle]] (cooler than fully charged [[Plasma Pistol]]). Ditch your Pistol for it (yes, the Pistol!). Afterward, get onto the second level, into the next room, and activate the light bridge and down the ramp.
''The Marine squad eagerly follows John-117 outside, where the Flood close in from all sides. Some Marines are attacked by Pod infectors, and their allies are forced to shoot them.''


An interesting thing to note is that when you return to the room the scared marine was in, in the next chapter, he will be oddly missing, with no blood and no signs of conflict with the [[Flood]]. Strange.
''As John-117 comes near the tower Rawley was speaking of, an odd blue object and a flotilla of [[Aggressor Sentinel|floating robotic automatons]] descend from the mist. The robots begin to slice away at any nearby Flood with [[Sentinel beam|built-in energy beams]], avoiding the Marines. After a few seconds of fighting around the base of the tower, the screen fades to white.''


===The Flood===
===343 Guilty Spark===
[[Image:Flood_attack.jpg|thumb|right|The Master Chief combats the Flood.]]
[http://www.youtube.com/watch?v=7NVtAPwE7Fc '''{''Original Cutscene''}''']
After are you're ready? Load your game and take a good look around the room. There are six doors on the ground level: one behind you, one in front of you, and two on either side of you. To your left, there is a supply of Pistol and Assault Rifle ammo (guess who it's from?) Fill up on Assault Rifle ammo, and then go to the door in front of you.
[http://www.youtube.com/watch?v=RzZsrfYu0ZI '''{Anniversary ''Cutscene''}''']


Right about now, that door will bust open and a wave of those little squid things you saw in the cinematic (Flood Infection Forms) will come for you. A word to the wise: if one catches you with your shields down, you're in trouble. But just slowly unload a few dozen Assault Rifle rounds into the main faction and melee the survivors (No need to waste ammo).
[[File:ChiefSparkCEA.png|thumb|300px|The Chief and 343 Guilty Spark meet for the first time.]]
As you finish off the main portion, the door on your right is going to bust open too. Feel free to unload the rest of your Assault Rifle magazine into that swarm. The door on your left is going bust open now, and this wave is pretty big, so I prefer to toss a Frag Grenade to clear out the first couple dozen, and unload on the rest with your automatic weapon.


Now, the door you came through is going to bust open, revealing a bunch of Infection Forms and a couple of infected Elites. Tip for Pros: Pause the game if you are hyperventilating, scared, or freaked out. Once you're back to normal, unleash the pistol on them. The [[Flood]] don't have shields, but they pack one hell of a punch, and you want to stay pretty far away from them. Use the pistol on the general area of their chest, as they don't really have a head to aim at. The tentacles make a good target.
''John-117 suddenly finds himself enveloped in [[Teleportation grid|a bright gold light]], and then appears on top of one of the legs of the tower. The blue object hovers in front of him. The Chief instinctively points his weapon at it.''


After a few seconds, that entire group of nasty Flood should be dead. Head up the ramp you came in by, but watch out for more Combat Forms just waiting to ambush you. If you see them, you could always neatly blast them in the chest with your [[MD6|M6D Pistol]], but it's more satisfying, in my opinion, to unload the [[MA5B Assault Rifle|MA5B]] on full auto. Ah, the joy of 7.62 mm rounds.
*'''[[343 Guilty Spark]]''': "Greetings. I am the [[Monitor]] of [[Installation 04]]. I am 343 Guilty Spark."


In the next room, a pack of Flood are taking on the [[Covenant]]. Stay on the upper level and exit through the door to the right. Head through the hallway to find yourself in another roomful of Flood, and this time there is no Covenant to distract them from you. Oh no! Well, actually, this isn't as dire a situation as it looks like. Stay on the upper level and back into a corner. Fire a few shots to get the attention of the Flood. They'll all gather into your corner, but not one of them will have the brains to try and jump up onto your upper level. Now, between the wall and the upper level, there is a tiny crack. Just big enough for a frag grenade! Well, well! I don't think I have to tell you what to do here. Exit Flood. Drop down; clear out any survivors, and head through the door below the one you entered by. Follow the hall back to the previous room.
''The Chief slowly lowers his assault rifle. Gunfire is still heard below, and bright beams slice through the dark swamp. The Chief and the Monitor ignore the commotion.''


The Flood should be done with the Covenant here by now. Peek out of the hall, gun down anything close by with the M6D, and then retreat into the doorway. When the Flood come for you, unleash the Assault Rifle on them, and rinse and repeat as necessary. Yes, you fools! Chew full metal jacket death! Ahem. Head back through the disgustingly blood-spattered hall to the door on the right. This next room has Covenant and Flood again. Wait a while for the entire Covenant to die, and then use the same strategy as before on the remaining Flood. Once everything is dead, jump up the stack of Covenant crates to get to the upper level. There might be a few Jackals or Grunts that hid from the Flood up here. Get them with the MA5B.
*'''343 Guilty Spark''': "Someone has released the Flood. My function is to prevent it from leaving this installation. But I require your assistance. Come. This way."


There are two doors up here. One is near where the Covenant were. We'll go through there eventually, but right now, we want to power up the [[Bridges|Energy bridge]] and head directly across. Hey, the elevator you got down here on! Fancy that! Well, the Flood fancies it, anyway. They come at you in droves, but you can use the same strategy you've been using. Hold the doorway with the Assault Rifle and grenades, and then finish things up with a pistol. This is one of the reasons I dislike the Flood: they make most strategies ineffective; so that there's only one or two ways you can play each fight. Now, get on the elevator and press go! Shoot! I guess the Flood broke it.
''John-117 and the Monitor vanish in another series of gold flashes.''


Now, go back through the door the Covenant were at. Here we have no enemies (for once), a load of ammo and health (for once) and the M90 Shotgun. The M90 is your prize; for the rest of the game, it'll be your go-to gun, as the pistol becomes gradually less effective. So, time to make use of the 8-gauge. This reduces the Flood from evil alien space zombies to playthings before your awesome might.
*'''Rawley (COM)''': "Chief, I've lost your signal! Where'd you go? Chief? Chief!"


After the next hall, we come to another elevator room. This time, though, you don't need to camp in the doorway! Turn that shotgun on and blaze a path through the Flood. Once you're done, hop on the elevator and—well, sometimes you have to sink before you rise. Right? Well, you're going down. In more ways than one.
''Fades to black.''


The elevator shaft's bottom can be a bit tricky. The Flood has really got you surrounded here. Luckily, a bit of jumping around and M90-ing will see you through the danger. Head to the right side of the door climb up on the crates, and grab the Overshield as soon as those Flood are all dead. Amazingly, in the next room, there's a couple of Marines left. If you are able, you can save them, but mostly, you should just worry about yourself and let them eat the path. By "worry about yourself" I mean, "be a cowardly fool". Grab one of the camouflages and start firing some shotgun rounds into the Flood down below, coupled with grenades whenever you feel one is needed. The shotgun, despite its reputation as a close-range nightmare, is actually pretty decent at long ranges too; you just need to aim carefully. After about a magazine from it, those Flood should be dead. Once they're all cold, grab the other Active Camo and head down onto the lower level. Exit through the blown-out door. The next split-path hallway has Flood hiding on either side, so be careful. If you get surrounded, you're pretty much hosed.
''Level ends.''


The next room is pretty normal. Flood are on the lower and upper levels, but there aren't too many of them. Jump up on the flaming pile of rubble. Grab the ammo and health, and then jump up onto the upper floor. Leave through the only open door. Keep going straight across the next room. Enter the next room. You're on top with Flood below. Luckily, you can use the "grenade through the wall gap" trick again, killing most of the Flood here. Drop down and blow away the survivors, then leave through the broken door. The next room is more or less the same as the last one, only now you're on the bottom. A shotgun shell for each Flood form, and you're on your way again. Directly across the room from the door you came in by is an exit. You'll run into a load of Flood in this hall, so open up with the shotgun. You're about to get a chance to refill on ammo, so don't worry about conservation. In the next room is a fallen pillar with health and a lot of needles and shells on top. Stock up, then jump from there to the upper level. The next hall is clear of Flood.

There is a [[Bridges|Energy bridge]] switch in this next area, as well as a bunch of Flood on the ground floor. You could try and clean them out, but I wouldn't recommend it. Extend the [[Bridges|Energy bridge]] and go across to the door. A LOT of Flood will come out—there are at least ten of them in the doorway, they're so bunched up that a couple of grenades can kill them all. Mop up the stragglers with the shotgun. Head on through once you're sure everything is dead. Finally, another elevator. The first time I played this, I decided that if this elevator went down too, I would kill myself.
==Production notes==
{{Main|Development of Halo: Combat Evolved}}
The design of ''343 Guilty Spark'' was initially developed by [[Bungie]] designer [[Paul Bertone]], but it was eventually given to fellow designer [[Jaime Griesemer]], who also addded splattered blood decals and the barricaded rooms.{{Ref/YouTube|Id=IGN|9ndZbg8Mr-Q|IGN|Halo: Combat Evolved Devs React to Speedrun (Martin O’Donnell, Marcus Lehto)}} Artists [[Justin Hayward]],{{Ref/Reuse|IGN}} [[Michael Wu]], and Eric Arroyo were responsible for the external environment; artist [[Shi Kai Wang]] also created concept art for the exterior swamp area.{{Ref/Book|AoH|Page=82-83}}


Luckily for you (and me) it goes up. There is a LOT of Marines up here—I count thirteen—and about half of them have shotguns. The rest have assault rifles. One or two may have plasma rifles. For a real challenge, try to kill them all. You might as well kill them. They'll just die anyway once you exit the building, and it's good practice for multiplayer.
There was an idea for the Paranoid Marine earlier in the development of this level in which he will stay alive, and when the player walks a distance away from him there was going to be a loud bang. If the player comes back, he would be found dead on the floor.{{Ref/Film|Id=Commentary|[[Halo 3 Legendary Edition|''Halo 3'' Legendary Edition]], Halo: Combat Evolved developer commentary}}


Anyway, if you aren't a treacherous swine who kills his soldiers, stock up on ammo and health one more time and move out of the base. The Marines know where to go, but they won't last very long. Rule of thumb: stick to the left. When you see a structure with big blinking lights, get close to it and stay close. The Marines, if they aren't already dead, will be soon. Then a flying blue ball, actually [[343 Guilty Spark (Monitor)|343 Guilty Spark]] will show up. He will then teleport you to the next level.  
According to Director of Cinematics [[Joseph Staten]], the creation of the mid-level cinematic was very time-consuming, as he needed to record every character's movement separately. The music playing during the Pelican ride with Sergeant Johnson and the Marines known as "[[flip music]]" is titled [[Shreddin']]. It was previously planned to license the song "Paint it Black" by the Rolling Stones. The pilot of the Pelican was voiced by [[Lorraine McLees]].{{Ref/Reuse|Commentary}} The dead Sangheili seen in the recording was specifically made for the cutscene due to it having its own file and model. Similarly, there is a unique Flood Pod infector used for Jenkin's recording cutscene. In the game's code, it is called a "nopop" and is specifically designed not to pop in the cutscene.


Interesting to note, by the way: It is possible for two 343 Guilty Sparks to appear in the cut scene— the one who's talking to the Chief and one floating aimlessly in the background. Probably just a glitch.
The events of the level were later expanded in the novel ''[[Halo: The Flood]]'':
*The Pelican, ''Victor 933'' have been only one of the many UNSC forces sent to investigate the alleged "weapons cache," thus explaining the reason for the large numbers of human [[Combat Forms]].
*John-117 took away the Crazed Marine's pistol and ordering him to calm down before returning the pistol to him. Although, the Marine never followed the orders.
*After encountering the Crazed Marine, John-117 also found the Elite later seen in Jenkins' helmet recording.
*The Corporal calling to Johnson and Keyes for help (voiced by [[Chris Carney]]) was identified as Corporal [[Lovik]].
*In the novel, Jenkins was the one who tried to run instead of Mendoza.
*John-117's initial encounter with human combat forms had the Spartan meeting an infected Mendoza and trying to communicate with the combat form, before being forced to defend himself from the aggressive combat form.
*When escaping from the facility, John-117 was noted to have been amazed to see that two to three marines were actually still present inside of the facility.  


Another "glitch" is the event is when one of the Marines aiding you is Sgt. Johnson, despite the fact that he is canonically believed dead for some time after. This has happened on a couple of occasions and is probably because his character model is counted as a normal Marine in Halo: CE. Privates Bisenti, Jenkins and Mendoza can also appear, despite having been taken over by the Flood.
Avery Johnson's escape from the facility was depicted in ''[[Breaking Quarantine]]'' from the ''[[Halo Graphic Novel]]'', while ''[[The Last Voyage of the Infinite Succor]]'' briefly depicted John-117 in the swamp during the events of this level.

===Glitches===
===Glitches===
If you save the [[Grunts]] and [[Jackals]] in the part after you encounter the [[Flood]], then you hide, they will start running around in fear.
{{Main|Glitches}}
*If you play in co-op and use the [[Riding a Pelican#343_Guilty_Spark|stay on Pelican]] glitch, then leave one player in the upper swamp and the other player walks along the tree trunk, then the player that is above can see the [[Flood]] up close and kill them easier. Note that these [[Flood]] do not attack the player.
*If the players play in co-op and use the [[Riding a Pelican#343 Guilty Spark|stay on Pelican]] glitch, then leave one player in the upper swamp and the other player walks along the tree trunk, then the player that is above can see the Flood up close and kill them easier.
*At the start of the level, the [[Flood]] that run into the mist at the big tree and the hill will appear as yellow blips, indicating that they are allies. This may be an error by the motion sensor, as later on in the game, they become enemies. Another possible explanation is that the Friend-Or-Foe tags that are still embedded inside the [[Flood]] forms, which could possibly be mutated [[Marines]], however on closer inspection, all of the [[Flood]] forms encountered are [[Elite]] [[combat forms]]. They are not invincible; if you hit them with enough pistol shots, they go down. This adds to the mystery and tension of the setting, creating an atmosphere of fear in the player.
*When the Covenant run away from the structure early in the level, there are [[MA5B assault rifle|assault rifle]] shots coming from the structure. To see this fully, use the "Stay in Pelican Trick" to get to the higher level of the swamp. Walk towards the entrance and slide down. They will see three MA5Bs floating in the air pointing at different angles firing wildly for a few seconds before disappearing.
*When the [[Covenant]] run away from the structure early in the level, there are [[MA5B Assault Rifle|Assault Rifle]] shots coming from the structure. To see this fully, use the "Stay in [[Pelican]] Trick" to get to the higher level of the swamp. Walk towards the entrance and slide down. You will see two MA5Bs and Captain Keyes' pistol pointing at different angles firing wildly for 5 seconds. In HMT (Halo Mod Tools) and HHT (Halo Hacker Tools) they appear under the scenery tag.
*If look closely at the dead Marine before John-117 lays him on the floor in the cutscene, one can see that the Marine will blink about two to four times despite the fact that he's supposed to be dead.
*During the [[Private Jenkins]]' helmet cam cutscene, when the [[Pelican]] dropship lands, you will see a crashed [[Pelican]] in the background. It's is also odd that the [[Marines]] do not infiltrate the downed [[Pelican]].
*If the player pushes the Shade turret in the way of Jenkins's scripted walk path prior to entering structure beforehand, he will get stuck in the spot where the turret was placed but continue his scripted movement while the rest of the squad moves ahead of him into the structure due to the fact that the recording takes place in the exact same places that the player previously traveled. This is because the game doesn't "clear out" the room and return it to the state that it was in when Jenkins and his companions were in it.
*When you use the [[Pelican]] glitch, the trees in the area are not solid and you can walk through them.
*It is possible to skip the entire Flood reveal and progress through the level directly from the first room after the first elevator. To do this when the player first enters the room they must drop down to the lower level and go left to the column with a light past the locked door. There the player must grenade jump and move back but stop moving just in time; this allows the player to end up in the floor above and if done correctly the player should land on the beam. The player must then move past a bit of geometry (there is a line in the floor) but taking care not to move too far towards the wall or else the player will fall back down. From here the player must crouch, quickly release crouch and jump forward, then time the release of forward and crouch again; done correctly the player will land on another beam. The player must then move straight towards the back wall (where the door that later allows the player to progress is). Finally near the wall the player needs to jump diagonally through the wall and possibly crouch, avoiding the glass window at the right but not going too far left. From here the level can be continued as normal as despite the door to get in being locked the door to the electric room and the door after are not.
*It is possible to return to the room where the Paranoid Marine was after watching Jenkin's helmet recording.{{Ref/YouTube|S1fm41ouBfI&t=700s|Generalkidd|Secret Mangled Elite Bodies}}
*Sometimes, if the player moves through the swamp at the end of the mission too quickly, the Marines will get stuck near the exit of the containment facility and not follow any further.
*On rare occasions, the player can encounter [[Flood Infection Form||Flood Infection Forms]] in the room where the Crazed Marine is located. They will not attack the player, but they will despawn fairly quickly.


====Mistakes====
===Mistakes===
*On the cut scene of the [[Private Jenkins]] helmet cam, you can see that the [[Infection Forms]] have holes in them.
*Sometimes, after the Master Chief has left dropship V933's crash site, the emergency distress call will start again prematurely, causing the message to overlap on itself.
*If you make your [[Marines]] turn on you at the tower, the [[Sentinels]] will attack them, though they mainly focus on the [[Flood]].
*The door that the Flood breaks open during the helmet camera cutscene is closed before triggering that cutscene. This can be seen through a window from the room before the cutscene triggers. If the player skips the cutscene before it gets to the part where the infection forms burst out, it will still be intact.
*The date on the timestamp of [[Private Jenkins]]' footage is May 27, 2552; months before the game actually takes place. This may be caused by a malfunction with the [[Marine]]'s armor, or a simple mistake by [[Bungie]].
*The dead Marine in the recording cutscene has a boonie hat on during the cutscene, though during gameplay he doesn't.
*If you look closely at the dead [[Marine]] before [[Master Chief]] lays him on the floor in the cutscene, you can see that the [[Marine]] will blink about 2 to 4 times despite the fact that he's dead.
*The date on the timestamp of [[Private Jenkins]]' footage is May 27, 2552; months before the game actually takes place, which is September. This is due to the Private not calibrating his helmet cam.{{Ref/Site|id=BWU4/7/06|URL=http://halo.bungie.net/news/content.aspx?type=topnews&link=updateqaapril|Site=Bungie.net|Page=Bungie Weekly Update 4/7/2006|Quote=When the Pillar of Autumn makes a jump, to adjust for normalized Earth time it will recalibrate equipment once position and relative position have been established. However, since the Autumn made a blind jump and straight into combat, no battle or field equipment was recalibrated. For that same reason, "north" on an assault rifle's built-in compass simply defaulted (per instructions from Keyes) to the largest visible source of gravity and magnetism - Threshold. The Earth-normal date was in fact September, in spite of what local equipment displayed. If poor old Jenkins had survived, his equipment would have been reset on the next (deliberate) jump.|D=07|M=02|Y=2021}}
*As you go through the level, you will come to a bit where there are three [[Jackals]] staring at a door. Kill them and walk through the door they were staring at and turn right. There is a gored [[Jackal]] with blue blood. However, [[Jackals]] have purple blood. The blue blood is the same blood that [[Grunts]] have. Though, the blue blood may have been from Grunts that were brutally killed and taken away for infection.
*In Jenkins' helmet cam, the Marines exit the Pelican from at least 10 feet off the ground.
*Behind one of the locked doors in a square-shaped hallway, there is a [[combat form]] trying to move through it. Its tentacles can be seen protruding through the door, and if you try to shoot it, it will attack you.
*The spoofer, which the Master Chief uses to open the door, only appears in the cutscene and not during actual gameplay.
*Sometimes, Sergeant Johnson will be in the surviving second squad, even though he escaped the structure by himself.{{Ref/Comic|HGN|Story=Breaking Quarantine}}
*During the ending cutscene, the Monitor can be seen flying around the tower as well as talking to the Chief. Similar to the previous error, this is because the Monitor is in the level before the cutscene, but isn't removed when the cutscene starts.
*A flashing red light can be seen attached to one of the trees surrounding the tower where the mission ends at. It is identical to the same red lights on the tower itself. This appears to be a placement mistake.


====Easter Eggs====
===Easter eggs===
*If you at any point of the first chapter reach the upper level of the swamp, (the easiest way is at the beginning of the level before you get off the pelican throw a grenade. This will keep you on the pelican and the pelican will take you to the upper level) you will find [[Private Mendoza]] comfortably standing at attention in the middle of nowhere. This is known as the [[Unarmed Marine Easter Egg]].
{{Main|Easter eggs}}
*During the first chapter of the level, dead corpses will spawn in the swamp when you are at some point of the inside of the installation. Walk back outside before the [[Private Jenkins]] helmet cam cutscene and bodies of [[Marines]] will be scattered through the lower level of the swamp. If you can make it to the upper level of the swamp (around Mendoza and such), you will find corpses of [[Covenant]] and [[Human]] [[Flood]] forms.
*There is a hidden [[Active Camouflage]] in this level. After killing the Kig-yar on the tree trunk that goes to the next part of the level, get onto the tree trunk. Once in the middle, stop and turn right. Jump down. There is a pipe leading up to a small ledge that is too high to jump to. There is a ramp. Go up it. Go as far back as one can on the ledge, and inside a bush there is an Active Camouflage power-up.
*If you don't kill any of the [[Grunts]] or [[Jackals]] outside in the swamp, when you meet up with your [[Marine]] allies, one of them will have a fully charged [[Plasma Pistol]].
*Private Jenkins' chip says "Do Not Eat". However it is only visible if the map is opened with HMT and look at the Bitmaps tab.
*There is a third elevator shaft that requires a mod to reach. There is no lift in it, just a fire where the panel to activate the lift would be.
*Sangheili Combat Forms can occasionally be seen up in the cliffs, and on top of fallen tree trunks during the initial outdoor part of the level. They cannot be killed, but body parts can be shot off, and they show as friendly on the radar.
*There is a hidden [[Active Camouflage]] in this level. After you kill the [[Jackals]] on the tree trunk that goes to the next part of the level, get onto the tree trunk. Once in the middle, you must stop. Turn right. Jump down. There is a pipe leading up to a small ledge that is too high to jump to. There is a ramp. Go up it. Go as far back as you can on the ledge, and inside a bush there is an [[Active Camouflage]] power-up.
*This level makes several references to the movie ''Aliens'', such as the banter between the marines witnessed by observing Jenkin's recording.
*Inside the structure, in the room with the Shade turrets, throw a plasma grenade under one of the turrets. If you get it just right it will blast up to the higher level of the room. After you've gotten past the Crazed Marine and you're on the higher level, melee the turret over to the door that you just came out of and get the back leg in the door. Proceed with the level. When you come back, the door you meleed the Shade turret into will be partially opened. Give the Shade one more melee and it will start shaking. Get into the turret and turn it so that the right is facing the door, then exit it and you will be in a hallway (this might take a few tries). Go through the hallway to enter the room that contains the unique dead Sangheili model. (Warning: there are Flood Combat Forms in here).
* The [[Halo: Combat Evolved Anniversary skulls#Recession skull|Recession skull]] is located to the left of the facility in a little drop behind a shade turret. When the player crosses the fallen tree, they'll see a shade turret blow up and assault rifle fire coming from the structure. Instead of going inside, immediately go to the left and keep against the back wall. You will come to a turret with a small drop behind it. Slide down the drop carefully; the skull is at the bottom.
* The [[Terminal (Halo: Combat Evolved Anniversary)#The Terminals|sixth Terminal]] is found while riding the third elevator that leads out of the underground facility. The terminal is above the doorway leading into the elevator room. It can be reached by activating the elevator, then timing it correctly and jumping off onto the platform below (there is only one possible attempt due to the lack of elevator controls on the top floor).

*Originally, there was going to be a licensed song that was played in-cutscene during the [[Pelican]] ride with [[Sergeant Johnson]] and the [[Marines]], but it was replaced with the flip music. The licensed song was going to be "Paint it Black" by the Rolling Stones. [[Marty O'Donnell]] stated this on the [[Halo 3]] Legendary Edition bonus disk.

*The actual song in-cutscene is called [[Shreddin']]. This song is from the game Marathon: Durandal, another [[Bungie]] creation.
*Mendoza can be found as a [[Hidden Marine]] in the upper area of the swamp if the player prevents the scripted exit from the Pelican by continuously throwing grenades out of the Pelican.
*It is possible to scale the [[Forerunner]] structure where you meet [[343 Guilty Spark (Monitor)|343 Guilty Spark]].
*This is one of three levels in the entire Halo trilogy where Needler ammunition magazines can be seen and used, the others being the ''Halo 2'' [[multiplayer]] map ''[[Uplift]]'', and the level ''[[Quarantine Zone]]''.
*This is the last level that [[Marines]] make their appearance to assist you in both cinematic and gameplay, although there are still some surviving ones on the installation.
*At the start of the level, the [[Flood]] that run into the mist at the big tree and the hill will appear as yellow blips, indicating that they are allies. This may be an error by the motion sensor, as later on in the game, they become enemies. Another possible explanation is that the Friend-Or-Foe tags that are still embedded inside the [[Flood]] forms, which could possibly be mutated [[Marines]], however on closer inspection, all of the [[Flood]] forms encountered are [[Elite]] [[Combat Forms]]. This adds to the mystery and tension of the setting, creating an atmosphere of fear in the player, as well as a foreshadowing of things to come. Of course, it could also have been made that way so they would not attack the player.
*At some point in the Level, after the 'The Helmet Cam' cutscene, in an open area (like the ones with Energy Bridges) ,you will find a few Marines, who ''can'' be saved. There are also [[Flood]] combat forms and [[Infection Forms]] in this room; if any attack the [[Marines]], they will die.

*If you skip the [[Private Jenkins]] helmet cam cut-scene, the door the [[Infection Forms]] break out of in the cut scene is closed and fixed, not broken.
*If players examine the floor to the right of the unlocked containment door, the player can find the neural chip that the Master Chief tossed aside after the "last recording" cutscene. However, it will disappear as if it was a particle over a short period of time.
*This is one of two levels in the entire Halo trilogy where you can see and use [[Needler]] ammo magazines, the other being the ''Halo 2'' multiplayer map [[Uplift]].
*If the player doesn't enter the installation in this level and choose to linger in the swamps, they can hear in the background Flood gurgles and howls.
*Sometimes, in the last cutscene, there will be another [[343 Guilty Spark (Monitor)|343 Guilty Spark]] floating around while the real one is talking to you.
*This level is one of the few rare campaign levels with red team and blue team [[List of Forerunner Symbols|symbols]]. They can be found near the first Flood encounter area and at any similar areas in the level.
*The area in the end of the level was later re-used for the map [[Backwash]] in ''[[Halo 2]]''.
*If the player returns to the elevator they entered the structure after meeting the Flood, looking up to where the elevator is, the player can clearly observe that it is on fire and damaged. Activating it will result in debris of it falling down to the shaft, and the Halo soundtrack [[Lament for Pvt. Jenkins]] will play again.
*In Jenkins' helmet cam, the Marines exit the Pelican from at least 10 ft off the ground.
**If the player is using Acrophobia Skull, the player can get out of the facility only to find corpses almost everywhere, mainly Grunts. Upon reaching the Landing Zone, the player can find a Pelican is holding position at where the Pelican carrying Sergeant Johnson stops before fast-forwarding. The player can board it as a passenger, but the Pelican won't move.
*If you stay on the pelican by throwing a grenade, the pelican will land at the upper levels of the swamps. If you jump on to of the pelican you will see that no one is driving it.
*It is possible to save the marines at the facility's bottom level from being killed. However, they will not follow the player any further. Instead, they will run in circles, occasionally dropping to one knee for a moment, and repeat the phrases: "I'm not sticking around to get killed.", "I'm gone, man!", "I'm out of here!", "You can't stop them!", "Forget this!", "Later, dude." and "This is suicide, man!" These lines are said by the Crewmen on {{UNSCShip|Pillar of Autumn}}. On a rare occasion, the surviving Marines will follow the player into the next room, but immediately retreat following a brief moment.

*This is the final level of ''Halo: Combat Evolved'' in which Marines are seen alive (with the exception of the non-canon Legendary ending on [[The Maw]] featuring [[Avery Junior Johnson|Johnson]]).

*Playing the level with the [[Halo: Combat Evolved Anniversary skulls#Grunt Funeral skull|Grunt Funeral Skull]] active in ''Halo Anniversary'' causes the Grunt corpses to detonate immediately after they spawn. This results in the player hearing explosions as they proceed further into the complex.

“ Creep through a swamp to meet the only enemy the Covenant fear. ”

343 Guilty Spark is the sixth campaign level in Halo: Combat Evolved.

In the swamps near a Flood containment facility on the surface of Installation 04, John-117 is dropped from Echo 419 to search for Captain Jacob Keyes who has been out of contact for over 12 hours. Soon, the Master Chief stumbles upon a structure and ventures within it, only to find out that the Marines accompanying the Captain have been slaughtered by an unknown force. After realizing the fate of the Marines, John fights his way out to the swamp and encounters a questionable ally.

Transcript[edit]

Well Enough Alone[edit]

Echo 419 arrives at the swamp.

{Original Cutscene} {Anniversary Cutscene}

View flies over a group of Kig-Yar and Unggoy running through a swamp, panicky and obviously in retreat. As it pans over them, the outline of a Pelican dropship can be seen through the fog and rain, which further materializes as the view draws closer.

  • Flight Captain Carol Rawley (COM): "The last transmission from the Captain's dropship was from this area. That was over twelve hours ago."

NOTE: In the Anniversary subtitles, Rawley adds, "...and we've been unable to reestablish contact with the Captain or his team."

{Gameplay}

  • Rawley (COM): "When you locate Captain Keyes, radio in, and I'll come pick you up."

In certain parts of the level, the player can hear a radio transmission coming from a crashed human dropship and a Covenant communications terminal. As it repeats, static pervades the transmission, and the signal fades in and out of clarity.

  • Dropship Victor 933's Pilot (Recording): "Dropship Victor 933-(static)-Pillar of Autumn-(static)-need assistance. We are under att-(static)-attack by some new kind of hostile-(static)-isn't Covenant. (Static) Captain Keyes has been captured by hostiles. (static) -dug in at a large structure in a swamp-(static)-We need to pull out. Please-(static)-I will set this message to repeat at-(static)-regular intervals. Dropship Victor 933, clear."

John-117 quickly finds the crashed dropship sending the message. There are weapons and supplies piled nearby, but no signs of life. An explosion in the distance throws the bodies of an Unggoy and a Kig-Yar through the air. He heads off to investigate and finds a crashed Covenant Spirit.

The Chief also encounters a small group of Unggoy and Kig-Yar, which he quickly eliminates, before crossing a log bridge. As he moves across the bridge, he sees several shadowy figures running around on the top of the cliff to the right. Also, his motion tracker shows seemingly friendly units in the swamp not too far from his location, but they suddenly disappear off radar.

When he reaches the other side, he hears assault rifle fire nearby. He investigates and sees a mob of Unggoy and Kig-Yar fleeing from a large entrance. A frag grenade explosion throws a Shade turret through the air. The fleeing Covenant regroup nearby and attack him out of fear.

John-117 kills the Covenant and hurries to the entrance, but finds no one there. A lift arrives for him. He takes the lift down into the depths of the structure.

John-117 passes through several large rooms and many smaller ones inside the structure, filled with Unggoy, Kig-Yar, empty Shade turrets, discarded weapons, and dead bodies - both Marine and Covenant. Curiously there is no sign of any Sangheili, alive or dead. In some rooms, Kig-Yar and Unggoy gather at the doorways as if expecting an attack. In one room, the Chief discovers a strange green-yellow substance falling from the ceiling.

The Chief arrives at the ominously empty facility.

As the Chief comes into an area blasted with gunfire and scorch marks, there is the sound of shattering glass. A lone Marine sits leaning against a wall, M6D magnum pointed at him. The Marine shoots at the Spartan if the Chief comes too close, while screaming at the top of his lungs the following phrases. He also fiddles around with his pistol a lot, checking to see if the magazine is full.

Paranoid Marine:

  • "Stay back! Stay back, you're not turning me into one of those things! I'll blow your brains out! Get away from me!"
  • "Gaaaaahh! Aaaaaahh! Don't touch me, you freaks! I won't be like you, I'll die first! Find your own hiding place, the monsters are everywhere!"
  • "Play dead! That's what I did...played dead. They took the live ones... Oh God, I can still hear them!"
  • (sobbing) "Monsters... Ahhhhhh! Ahhhhaaahhh..."
  • "Just leave me alone!"
  • "Sarge? Mendoza? Bisenti? Oh God...the things took them. Away, away, away, they went away... (mumbles and cries) They're gone! Get it? Gone!"
  • "They won't get me! Oh God... Oh God, I don't want to be like them. Please, please no, nooo..."

John-117 leaves him, and makes his way into the room, which is covered in dead Covenant bodies, blood, bullet holes and plasma scoring. Some areas of the floor are blackened with blasts from explosions. In some areas, small flecks of a greenish substance are found on the floor. The Chief finds a partially shattered walkway and ascends to the second floor. An assault rifle lies on the ground, pointing like an arrow towards the entrance of a room marked with ominous red Forerunner glyphs. The door appears to have been forced open. The Chief goes in, passes a dead Marine, and walks down a ramp.

The Chief comes down one of two ramps on either side of a doorway, which has been recently been forced open by a UNSC spoofer.

{Original Cutscene} {Anniversary Cutscene}

Private Jenkins' discarded helmet.

John-117 approaches the door cautiously and listens for any movement inside. Just as he is about to type a command into the spoofer, there is a noise behind him. He turns around, gun ready to shoot, but sees nothing. After a moment, he turns back to the door, places his gun on his shoulder and opens the door. When it opens, the body of a Marine falls into his arms. He advances a few paces, places the body on the floor gently while making sure nobody follows him through. He sweeps his assault rifle about the room.

The floor is covered in human blood. Discarded UNSC weapons litter the floor. John-117 also notices a helmet lying on the floor, and, crouching, moves swiftly towards it. Once there, he surveys the room one more time, places his rifle on the floor, and picks up the helmet. The name "JENKINS" is stamped across it. There is a large, jagged hole punched through the top of it. The Master Chief shakes his head. He then examines the helmet more closely and notices that the helmet recorder, near the Heads-up display, is still intact. He retrieves the M4 field disk and inserts it into a socket in his helmet.

Sergeant Johnson arguing with Bisenti over flip music.

The view switches to a night vision-enabled recording. Jenkins looks around the inside of a Pelican. There are several other Marines seated in the dropship with him. Flip music, Johnson's favorite genre, blares over the cabin speakers.

  • Private Manuel Mendoza: "Why do we always have to listen to this old stuff, Sarge?"
  • Staff Sergeant Avery Junior Johnson: "Watch your mouth, son. This "stuff" is your history. It should remind you grunts what we're fightin' to protect."
  • Mendoza: "Hey... if the Covenant wanna wipe out this particular part of my history, that's fine by me."
  • Private Bisenti: "Yeah... better it than us."
  • Johnson: "You ask 'em real nice next time you see 'em, Bisenti. I'm sure they'll be happy to oblige."
  • Pelican dropship pilot (COM): "LZ looks clear! I'm bringing us down!"

The Pelican descends to the ground.

  • Johnson: "Go, go, go!"

The Squad advances through the swamp towards the same structure the Chief is in.

  • Johnson: "Stay close, Jenkins!"

They reach the entrance and sweep their weapons across it, wary.

  • Johnson: "Mendoza! Move it up!"

Mendoza advances in a crouch, gun at the ready.

  • Johnson: (to Jenkins) "Wait here for the Captain and his squad, then get your ass inside."

Jenkins look behind the squad.

  • Johnson: "Okay, let's move!"

The fireteam heads into the structure.

The squad discovers an oddly-mutilated Sangheili corpse.

Inside the room where John-117 encountered the Paranoid Marine, the squad stands around a Sangheili carcass. Its chest is torn wide open. Private Mendoza is examining a similar corpse on the left hand side of the screen.

  • Private Kappus: "--which is weird, right? I mean...look at it."

Bisenti prods the Sangheili with his foot.

  • Private Kappus: "Something...scrambled the insides."

NOTE: In the Anniversary subtitles, Kappus says, "Something tore open its chest and scrambled the insides."

  • Johnson: "What's that? Plasma scoring?"
  • Kappus: "Yeah... I dunno. Maybe there was an accident. You know, friendly fire or something?"

Captain Keyes approaches the squad.

  • Johnson: "Looks like a Covenant patrol. Badass Elite units, all KIA."

Keyes looks down at the dead Sangheili.

  • Keyes: "Real pretty... Friend of yours?"
  • Kappus: "Nah, we just met."

Fade to black.

> PLAY >

The squad, along with Captain Keyes and his own squad, stand outside a locked door - the one the Chief has just come through.

  • Keyes: "Right. Well, let's get this door open."
  • Kappus: "I'll try, sir... But it looks like these Covenant worked pretty hard to lock it down."
  • Keyes: "Just do it, son!"
  • Kappus: "Yes, sir."

Kappus removes a spoofer from his pocket and sticks it to the door. He punches a few keys, and the door opens. He waves the squad through. Bisenti takes point through the door, Jenkins close behind him, and the rest of the squad fans out around him. An odd rumbling sound is heard.

  • Mendoza: "I've got a bad feeling about this..."
  • Johnson: "Boy, you always got a bad feelin' about something-"
  • Corporal Lovik (COM): "-Captain, Sarge (static) can you hear me?!"
  • Keyes: "What's going on, soldier?"
  • Lovik (COM): (panicked) "We've got contacts - lots of 'em - but...they're not Covenant... They're just tearing through us - what the?! Oh, nooooo...!"

The same hissing noises can be heard in the background.

  • Johnson: "Corporal? Do you copy, over?"

No response is given.

  • Johnson: "Mendoza, get your ass back up to Second Squad's position, and find out what the hell is goin' on."
  • Mendoza: "But sir-"
  • Johnson: "I don't have time for your lip, soldier! I gave you an order!"

The same noise that John-117 heard before entering the room is heard.

  • Kappus: "Sarge! Listen!"

The odd hissing noise grows louder and louder. Everyone scans the room, trying to find the source of the strange sounds.

  • Jenkins: "What is that?"
  • Johnson: "Where's that coming from, Mendoza?"
  • Mendoza: "Everywhere... I don't - there! (Spanish) ¡Mira!" (Look!)

Mendoza points to a nearby door, which has just exploded outwards. Small squid-like creatures swarm from it.

  • Private Riley: "Ahh...augh! Get it out! Get it out- augh!"

Riley lies on the ground, one of the Pod infectors attached to his chest. Bisenti tries to pull it off him.

  • Bisenti: "Hold still, hold still!"

Bisenti pulls the creature off of Riley, who goes limp. Bisenti struggles with the creature, which is now trying to infect him.

Sergeant Johnson and Captain Keyes fight back-to-back as their squad is overrun by the Flood.
  • Johnson: "Let 'em have it!"

The Marines and Captain Keyes open fire, to little effect. Pod infectors swarm them with overwhelming numbers.

  • Keyes: "Sergeant, we're surrounded!"
  • Johnson: "God dammit, Jenkins! Fire your weapon!"
  • Mendoza: "There are too many, Sarge!"
  • Johnson: "Don't even think about it, Marine!"

As the chaotic firefight continues, Mendoza dashes for the exit, abandoning his fireteam.

  • Mendoza: "Yo, this is loco!"
  • Keyes: "Get back here, Marine! That's an order!"

The Marine squad is overtaken, still firing, while their blood sprays as Pod infectors continue to crawl onto them. Another group of infectors drop from the ceiling, right between Johnson, Keyes and Jenkins.

  • Johnson: "Jenkins!"

Several infectors attack Jenkins, blocking out his helmet cam. The screen cuts to black.

> UNEXPECTED HALT X [WND/INCAP/KIA? Ref.a4 3d.3]

> END RECORD VIEW [2552.5.27.6:39:23 L]

John-117 removes the chip from his helmet, shakes his head, and tosses the chip to the ground. The noises begin again. He readies his assault rifle.

The Flood[edit]

{Gameplay}

The door John-117 came through is now locked. Three doors holding dozens of Pod infectors break open one at a time, their inhabitants attacking him.

The entrance breaks open. Massive amounts of infectors skitter inside, followed by unarmed Sangheili combat forms.

John-117 escapes the facility, encountering Flood forms and some Covenant infantry struggling to survive.

A swarm of pod infectors approach John-117 in a Flood containment facility on Installation 04.
John is about to be attacked by Pod infectors that broke quarantine in the containment facility.

John-117 tries to take the elevator he entered with, but while he waits for it to come down, it suddenly falls down and crashes down to the bottom of the facility.

After some fighting, John-117 arrives at another elevator, but it goes deeper underground and Unggoy blood is seen painted on the elevator's shaft. At the bottom of the shaft, he's attacked by armed combat forms - both infected Sangheili and humans. This detour forces him to fight his way back up.

John-117 eventually sees two (three on Easy/Normal difficulty) Marines armed with shotguns and assault rifles fighting the Flood.

Although their weapons give them a distinct advantage, a single Pod infector or a single combat form attack can kill them.

If they survive, they hold their position inside the room, saying the following in random order:

  • "This is suicide (man)!"
  • "I'm gone, man!"
  • "I'm not sticking around to get killed!"
  • "We/I can't stop them!"
  • "Forget this!"
  • "Later, dude!"
  • "I've had enough of this crap!"
  • "I'm outta here!"

John-117 reaches the final elevator and rises to an exit from the structure.

  • Rawley (COM): "This is Echo 419. Chief, is that you? I lost your signal when you disappeared inside the structure. What's going on down there? I'm tracking movement all over the place!"

John-117 reaches the top where a trapped group of 10 Marines are holding out.

It is obvious they used a lot of ammo to escape, and it is all stacked in a pile. Most Marines hold shotguns and assault rifles, one or two have plasma rifles.

The Marines of second squad and John-117 desperately attempt to escape the Flood-infested swamps of Installation 04.
John-117 leads the Marine survivors to escape the Flood-infested swamp.
  • Chips Dubbo: "Sir! Thank God you're here. We've been lost out here for hours. After we lost contact with the rest of the mission, we, we headed for the RV point, and then these-these....these things...they ambushed us. We've gotta get out of here!"
  • Flight Captain Rawley (COM): "There's a large tower a few hundred meters from your current position. Find a way above the fog and foliage canopy and I can move in and pick you up."

The Marine squad eagerly follows John-117 outside, where the Flood close in from all sides. Some Marines are attacked by Pod infectors, and their allies are forced to shoot them.

As John-117 comes near the tower Rawley was speaking of, an odd blue object and a flotilla of floating robotic automatons descend from the mist. The robots begin to slice away at any nearby Flood with built-in energy beams, avoiding the Marines. After a few seconds of fighting around the base of the tower, the screen fades to white.

343 Guilty Spark[edit]

{Original Cutscene} {Anniversary Cutscene}

The Chief and 343 Guilty Spark meet for the first time.

John-117 suddenly finds himself enveloped in a bright gold light, and then appears on top of one of the legs of the tower. The blue object hovers in front of him. The Chief instinctively points his weapon at it.

The Chief slowly lowers his assault rifle. Gunfire is still heard below, and bright beams slice through the dark swamp. The Chief and the Monitor ignore the commotion.

  • 343 Guilty Spark: "Someone has released the Flood. My function is to prevent it from leaving this installation. But I require your assistance. Come. This way."

John-117 and the Monitor vanish in another series of gold flashes.

  • Rawley (COM): "Chief, I've lost your signal! Where'd you go? Chief? Chief!"

Fades to black.

Level ends.

Production notes[edit]

Main article: Development of Halo: Combat Evolved

The design of 343 Guilty Spark was initially developed by Bungie designer Paul Bertone, but it was eventually given to fellow designer Jaime Griesemer, who also addded splattered blood decals and the barricaded rooms.[2] Artists Justin Hayward,[2] Michael Wu, and Eric Arroyo were responsible for the external environment; artist Shi Kai Wang also created concept art for the exterior swamp area.[3]

There was an idea for the Paranoid Marine earlier in the development of this level in which he will stay alive, and when the player walks a distance away from him there was going to be a loud bang. If the player comes back, he would be found dead on the floor.[4]

According to Director of Cinematics Joseph Staten, the creation of the mid-level cinematic was very time-consuming, as he needed to record every character's movement separately. The music playing during the Pelican ride with Sergeant Johnson and the Marines known as "flip music" is titled Shreddin'. It was previously planned to license the song "Paint it Black" by the Rolling Stones. The pilot of the Pelican was voiced by Lorraine McLees.[4] The dead Sangheili seen in the recording was specifically made for the cutscene due to it having its own file and model. Similarly, there is a unique Flood Pod infector used for Jenkin's recording cutscene. In the game's code, it is called a "nopop" and is specifically designed not to pop in the cutscene.

The events of the level were later expanded in the novel Halo: The Flood:

  • The Pelican, Victor 933 have been only one of the many UNSC forces sent to investigate the alleged "weapons cache," thus explaining the reason for the large numbers of human Combat Forms.
  • John-117 took away the Crazed Marine's pistol and ordering him to calm down before returning the pistol to him. Although, the Marine never followed the orders.
  • After encountering the Crazed Marine, John-117 also found the Elite later seen in Jenkins' helmet recording.
  • The Corporal calling to Johnson and Keyes for help (voiced by Chris Carney) was identified as Corporal Lovik.
  • In the novel, Jenkins was the one who tried to run instead of Mendoza.
  • John-117's initial encounter with human combat forms had the Spartan meeting an infected Mendoza and trying to communicate with the combat form, before being forced to defend himself from the aggressive combat form.
  • When escaping from the facility, John-117 was noted to have been amazed to see that two to three marines were actually still present inside of the facility.

Avery Johnson's escape from the facility was depicted in Breaking Quarantine from the Halo Graphic Novel, while The Last Voyage of the Infinite Succor briefly depicted John-117 in the swamp during the events of this level.

Trivia[edit]

Glitches[edit]

Main article: Glitches
  • If the players play in co-op and use the stay on Pelican glitch, then leave one player in the upper swamp and the other player walks along the tree trunk, then the player that is above can see the Flood up close and kill them easier.
  • When the Covenant run away from the structure early in the level, there are assault rifle shots coming from the structure. To see this fully, use the "Stay in Pelican Trick" to get to the higher level of the swamp. Walk towards the entrance and slide down. They will see three MA5Bs floating in the air pointing at different angles firing wildly for a few seconds before disappearing.
  • If look closely at the dead Marine before John-117 lays him on the floor in the cutscene, one can see that the Marine will blink about two to four times despite the fact that he's supposed to be dead.
  • If the player pushes the Shade turret in the way of Jenkins's scripted walk path prior to entering structure beforehand, he will get stuck in the spot where the turret was placed but continue his scripted movement while the rest of the squad moves ahead of him into the structure due to the fact that the recording takes place in the exact same places that the player previously traveled. This is because the game doesn't "clear out" the room and return it to the state that it was in when Jenkins and his companions were in it.
  • It is possible to skip the entire Flood reveal and progress through the level directly from the first room after the first elevator. To do this when the player first enters the room they must drop down to the lower level and go left to the column with a light past the locked door. There the player must grenade jump and move back but stop moving just in time; this allows the player to end up in the floor above and if done correctly the player should land on the beam. The player must then move past a bit of geometry (there is a line in the floor) but taking care not to move too far towards the wall or else the player will fall back down. From here the player must crouch, quickly release crouch and jump forward, then time the release of forward and crouch again; done correctly the player will land on another beam. The player must then move straight towards the back wall (where the door that later allows the player to progress is). Finally near the wall the player needs to jump diagonally through the wall and possibly crouch, avoiding the glass window at the right but not going too far left. From here the level can be continued as normal as despite the door to get in being locked the door to the electric room and the door after are not.
  • It is possible to return to the room where the Paranoid Marine was after watching Jenkin's helmet recording.[5]
  • Sometimes, if the player moves through the swamp at the end of the mission too quickly, the Marines will get stuck near the exit of the containment facility and not follow any further.
  • On rare occasions, the player can encounter |Flood Infection Forms in the room where the Crazed Marine is located. They will not attack the player, but they will despawn fairly quickly.

Mistakes[edit]

  • Sometimes, after the Master Chief has left dropship V933's crash site, the emergency distress call will start again prematurely, causing the message to overlap on itself.
  • The door that the Flood breaks open during the helmet camera cutscene is closed before triggering that cutscene. This can be seen through a window from the room before the cutscene triggers. If the player skips the cutscene before it gets to the part where the infection forms burst out, it will still be intact.
  • The dead Marine in the recording cutscene has a boonie hat on during the cutscene, though during gameplay he doesn't.
  • The date on the timestamp of Private Jenkins' footage is May 27, 2552; months before the game actually takes place, which is September. This is due to the Private not calibrating his helmet cam.[6]
  • In Jenkins' helmet cam, the Marines exit the Pelican from at least 10 feet off the ground.
  • The spoofer, which the Master Chief uses to open the door, only appears in the cutscene and not during actual gameplay.
  • Sometimes, Sergeant Johnson will be in the surviving second squad, even though he escaped the structure by himself.[7]
  • During the ending cutscene, the Monitor can be seen flying around the tower as well as talking to the Chief. Similar to the previous error, this is because the Monitor is in the level before the cutscene, but isn't removed when the cutscene starts.
  • A flashing red light can be seen attached to one of the trees surrounding the tower where the mission ends at. It is identical to the same red lights on the tower itself. This appears to be a placement mistake.

Easter eggs[edit]

Main article: Easter eggs
  • There is a hidden Active Camouflage in this level. After killing the Kig-yar on the tree trunk that goes to the next part of the level, get onto the tree trunk. Once in the middle, stop and turn right. Jump down. There is a pipe leading up to a small ledge that is too high to jump to. There is a ramp. Go up it. Go as far back as one can on the ledge, and inside a bush there is an Active Camouflage power-up.
  • Private Jenkins' chip says "Do Not Eat". However it is only visible if the map is opened with HMT and look at the Bitmaps tab.
  • Sangheili Combat Forms can occasionally be seen up in the cliffs, and on top of fallen tree trunks during the initial outdoor part of the level. They cannot be killed, but body parts can be shot off, and they show as friendly on the radar.
  • This level makes several references to the movie Aliens, such as the banter between the marines witnessed by observing Jenkin's recording.
  • Inside the structure, in the room with the Shade turrets, throw a plasma grenade under one of the turrets. If you get it just right it will blast up to the higher level of the room. After you've gotten past the Crazed Marine and you're on the higher level, melee the turret over to the door that you just came out of and get the back leg in the door. Proceed with the level. When you come back, the door you meleed the Shade turret into will be partially opened. Give the Shade one more melee and it will start shaking. Get into the turret and turn it so that the right is facing the door, then exit it and you will be in a hallway (this might take a few tries). Go through the hallway to enter the room that contains the unique dead Sangheili model. (Warning: there are Flood Combat Forms in here).
  • The Recession skull is located to the left of the facility in a little drop behind a shade turret. When the player crosses the fallen tree, they'll see a shade turret blow up and assault rifle fire coming from the structure. Instead of going inside, immediately go to the left and keep against the back wall. You will come to a turret with a small drop behind it. Slide down the drop carefully; the skull is at the bottom.
  • The sixth Terminal is found while riding the third elevator that leads out of the underground facility. The terminal is above the doorway leading into the elevator room. It can be reached by activating the elevator, then timing it correctly and jumping off onto the platform below (there is only one possible attempt due to the lack of elevator controls on the top floor).

References[edit]

  • In the Halo 3 level, Floodgate, there is another Crazed Marine, though this one won't shoot at the player. Instead, he points the pistol at his head occasionally, contemplating suicide.
  • The line "I have a bad feeling about this" is another homage to Aliens or Star Wars.
  • The swamps are covered by some kind of glowing plants. Similar plants may be seen in High Charity in Halo 2.

Miscellaneous[edit]

Mendoza standing in the upper area of the swamp.
  • Mendoza can be found as a Hidden Marine in the upper area of the swamp if the player prevents the scripted exit from the Pelican by continuously throwing grenades out of the Pelican.
  • This is one of three levels in the entire Halo trilogy where Needler ammunition magazines can be seen and used, the others being the Halo 2 multiplayer map Uplift, and the level Quarantine Zone.
  • At the start of the level, the Flood that run into the mist at the big tree and the hill will appear as yellow blips, indicating that they are allies. This may be an error by the motion sensor, as later on in the game, they become enemies. Another possible explanation is that the Friend-Or-Foe tags that are still embedded inside the Flood forms, which could possibly be mutated Marines, however on closer inspection, all of the Flood forms encountered are Elite Combat Forms. This adds to the mystery and tension of the setting, creating an atmosphere of fear in the player, as well as a foreshadowing of things to come. Of course, it could also have been made that way so they would not attack the player.
  • During the first chapter of the level, corpses will spawn in the swamp when the player is at some point of the inside of the installation. Walk back outside before the Private Jenkins helmet cam cutscene and bodies of Marines will be scattered through the lower level of the swamp. If one can make it to the upper level of the swamp (around Mendoza and such), one will find corpses of Covenant and Human Flood Combat Forms.
  • If players examine the floor to the right of the unlocked containment door, the player can find the neural chip that the Master Chief tossed aside after the "last recording" cutscene. However, it will disappear as if it was a particle over a short period of time.
  • If the player doesn't enter the installation in this level and choose to linger in the swamps, they can hear in the background Flood gurgles and howls.
  • This level is one of the few rare campaign levels with red team and blue team symbols. They can be found near the first Flood encounter area and at any similar areas in the level.
  • If the player returns to the elevator they entered the structure after meeting the Flood, looking up to where the elevator is, the player can clearly observe that it is on fire and damaged. Activating it will result in debris of it falling down to the shaft, and the Halo soundtrack Lament for Pvt. Jenkins will play again.
    • If the player is using Acrophobia Skull, the player can get out of the facility only to find corpses almost everywhere, mainly Grunts. Upon reaching the Landing Zone, the player can find a Pelican is holding position at where the Pelican carrying Sergeant Johnson stops before fast-forwarding. The player can board it as a passenger, but the Pelican won't move.
  • It is possible to save the marines at the facility's bottom level from being killed. However, they will not follow the player any further. Instead, they will run in circles, occasionally dropping to one knee for a moment, and repeat the phrases: "I'm not sticking around to get killed.", "I'm gone, man!", "I'm out of here!", "You can't stop them!", "Forget this!", "Later, dude." and "This is suicide, man!" These lines are said by the Crewmen on UNSC Pillar of Autumn. On a rare occasion, the surviving Marines will follow the player into the next room, but immediately retreat following a brief moment.
  • This is the final level of Halo: Combat Evolved in which Marines are seen alive (with the exception of the non-canon Legendary ending on The Maw featuring Johnson).
  • The swamp area in the end of the level was later re-used for the multiplayer map Backwash in Halo 2.
  • Playing the level with the Grunt Funeral Skull active in Halo Anniversary causes the Grunt corpses to detonate immediately after they spawn. This results in the player hearing explosions as they proceed further into the complex.
  • This, and the subsequent level The Library, are the only levels where the player will not encounter any Covenant Elites.
