'''The Maw''' is the tenth and final level in ''[[Halo: Combat Evolved]]''. 

==Summary==
The [[John-117|Master Chief]] makes his way through the ''[[UNSC Pillar of Autumn|Pillar of Autumn]]''<nowiki>'</nowiki>s wreck in order to detonate the ship's fusion reactors and destroy Halo, the [[Flood]], and the [[Covenant Empire|Covenant]] armada, thus preventing the destruction of humans and potentially, all sentient life in the galaxy. Just like the previous two levels, the player has no allies.

===. . . And the Horse You Rode In On===
[http://www.youtube.com/watch?v=2Bpf96l71GE '''{''Cutscene''}''']

''The view skims low over a large body of water, tinted gold by an oncoming sunrise. A Gregorian chant rises.''

''View slowly pans up as it flies over the sand, revealing a burnt coastline, and a giant gouge where the terrain has been ripped away and the sea has flooded into the newly-formed canyon. At the top of that canyon rises the massive stern of the ''[[UNSC Pillar of Autumn|Pillar of Autumn]]'', relatively intact. View circles around the side and front of her, revealing that her nose is hanging just slightly off a massive cliff, and that the antennae along the bow have been bent and torn away. The entire bow has been burnt badly; the metal is scarred. The once powerful cruiser looks almost pitiful, and it is clear its only purpose left is to destroy Halo. As the view circles around to reveal the starboard side, a slightly damaged, smoking [[Banshee]] drifts into view.''

''Cuts to a view of the outside through one of the ship's [[Bumblebee]] airlocks. The damaged [[Banshee]] comes into the frame and veers wildly towards the ''Pillar of Autumn.

*'''[[Cortana]]''': ''(panicked)'' "This thing is falling apart!"

*'''[[Master Chief Petty Officer]] [[John 117]]''': ''(calmly)'' "It'll hold."

*'''Cortana''': "We're not gonna make it!"

*'''John-117''': "We'll make it."

*'''Cortana''': ''(urgently)'' "Pull up! Pull up!"

''The Banshee drops just before reaching the Bumblebee slip and smashes into the side of the ''Pillar of Autumn'', sending debris and fire hurling out madly.''

[[File:crashlanding.jpg|150px|right|thumb|Master Chief climbing into a Bumblebee port.]]

*'''Cortana''': ''(sardonic)'' "You did that on purpose, didn't you?"

''The Master Chief's hand appears from below and grips the edge of the slip, and he pulls himself up and onto the ''Pillar of Autumn''.''

'''{''Gameplay''}'''

*'''Cortana''': "We need to get to the bridge. From there, we can use the [[Captain Keyes|Captain]]'s neural implants to initiate an overload of the ship's fusion engines. The explosion should damage enough systems below it to destroy the [[Installation 04|ring]]."

''As the Master Chief heads for the bridge, he discovers Covenant, Flood, and Sentinels fighting through out the ship. Eventually, he reaches the bridge.''

*'''Cortana''': "The bridge. We made it. Let's get to work."

''The Master Chief clears out the Covenant Spec Ops team guarding the bridge.''

*'''Cortana''': "I need you to upload me into the control systems. The terminal is located next to the main view screen."

[http://www.youtube.com/watch?v=_imCZ-b1--U '''{''Cutscene''}''']

''The Master Chief takes Cortana's chip from his helmet and inserts it into the cylindrical terminal near the front of the bridge. Cortana's avatar appears above it.''

*'''Cortana''': "I leave home for a few days, and look what happens. This won't take long."

''She concentrates for a moment, and the main screen flickers to life. "Self Destruct Sequence Initiated" is displayed across the top, and numbers begin counting down from what is, as far as we can tell, a random starting point between five and fifty-nine minutes.''

*'''Cortana''': "There. That should give us enough time to make it to a lifeboat and put some distance between ourselves and Halo before the detonation."

''The Master Chief moves to unplug Cortana from the terminal, but stops abruptly when he hears an all-too-familiar voice.''

*'''[[343 Guilty Spark]] (COM)''': "I'm afraid that's out of the question, really."

*'''Cortana''': ''(groans)'' "Oh, hell."

*'''343 Guilty Spark (COM)''': "Ridiculous! That you would imbue a warship's AI with such a wealth of knowledge! Weren't you worried it might be captured? Or destroyed?"

''Cut to Cortana.''

*'''Cortana''': "He's in my data arrays, a local tap!"

''Cut to 343 Guilty Spark in the engine room. He's busy scanning a console.''

*'''343 Guilty Spark''': "You can't imagine how exciting this is! To have a record of all of our lost time! Human history, is it? Fascinating."

''343 Guilty Spark flutters around Engineering, as groups of [[Sentinel]]s hover around in the background, and scans another console.''
[[File:Interfacing.jpg|150px|right|thumb|343 Guilty Spark collecting information.]]

*'''343 Guilty Spark:''' "Oh, how I will enjoy every moment of its categorization! And to think that you would destroy this installation, as well as this record. I am ''shocked''. Almost too shocked for words."

''Cut to the bridge. A tone sounds over the ship's speakers. The countdown timer freezes.''

*'''Cortana''': ''(with a note of frustrated awe in her voice)'' "He stopped the self-destruct sequence..."

''The Master Chief surveys the bridge carefully with his [[MA5B Individual Combat Weapon System|Assault Rifle]], never missing a beat.''

*'''343 Guilty Spark (COM)''': "Why do you continue to fight us, [[Reclaimer]]? You cannot win! Give us the construct, and I will endeavor to make your death relatively painless and -"

''He is cut off as another tone sounds.''

*'''Cortana''': "At least I still have control over the comm channels."

*'''John-117''': "Where is he?"

*'''Cortana''': "I'm detecting taps throughout the ship, Sentinels most likely. As for the [[Monitor]] ... he's in Engineering. He must be trying to take the core offline! Even if I could get the countdown restarted ... I don't know what to do." ''(She shrugs her arms in desperation)''

*'''John-117''': "How much firepower would you need to crack one of the engine's shields?"

*'''Cortana''': "Not much. A well-placed grenade perhaps, but why-"

[[File:grenadetoss.jpg|150px|right|thumb|Master Chief holding a fragmentation grenade.]]

''She turns to see the Master Chief, who is calmly tossing a [[M9 High-Explosive Dual-Purpose Grenade|fragmentation grenade]] up and down''

*'''Cortana''': ''(nods)'' "Okay, I'm coming with you."

''The Chief reaches for Cortana just as a squad of Sentinels descends from above and take position along the shattered windows of the bridge''

*'''Cortana''': "Chief! Sentinels!"

''The Sentinels open fire, shattering the main display and touching off the Chief's shields. The Chief quickly drops behind cover, removes Cortana from the terminal and places her into his helmet, and raises his rifle.''

'''{''Gameplay''}'''

''The Chief dispatches the Sentinels and leaves the bridge.''

*'''Cortana''': "The ship was heavily damaged when it crashed. Head to the cryochamber. We should be able to get to the engine room through there."

''The Chief heads for Engineering, fighting past more Flood, Covenant, and Sentinels. Along the way, he makes a brief detour to the ship's Armory to stock up on weapons. Inside the Armory, he is ambushed by a group of Flood, including several cloaked Combat Forms (presumably infected [[Stealth Elites]]). He defeats these enemies and hurries to Engineering.''

===Light Fuse, Run Away===

*'''Cortana''': "Engine room located. We're here."

''The Chief enters Engineering which is crawling with [[Flood]] and Sentinels. Guilty Spark is also present.''

*'''Cortana''': "Alert! The Monitor has disabled all command access. We can't restart the countdown. The only remaining option is to detonate the ship's fusion reactors. That should do enough damage to destroy Halo. Don't worry; I have access to all of the reactor schematics and procedures. I'll walk you through it. First, we need to pull back the exhaust couplings. That will expose a shaft that leads to the primary fusion drive core."

''Throughout this entire sequence, 343 Guilty Spark mumbles randomly at the Chief, trying to convince him to spare the installation.''

*"You would destroy this installation, as well as this fascinating record?"
*"Do you require medical attention?"
*"Your behavior is not in accordance with established protocols."
*"Oh, how touching."
*"Detaching the failsafe just now?"
*"Please. Surrender the construct and I will endeavor to make the necessary repairs as quickly as possible."
*"The Flood continue to multiply, Reclaimer!"
*"Why do you continue to ignore your task?"
*"Are you perhaps ill?"
*"Why do you continue to resist us, Reclaimer?"
*"Inconsistent!"
*"Inadequate safeguards." 
*"This AI construct possesses far too much data."
*"Weren't you worried it might be compromised?"
*"Unacceptable, Reclaimer!"
*"Not acceptable, Reclaimer. You must surrender the construct, so that we may return to our appointed task."
*"Your behavior necessitates repair and revision."
*"Surrender the construct to me, or I will be forced to take you offline permanently."
*"Reclaimer, we must keep moving ... Reclaimer?"

''The Chief opens one of the manifolds.''

*'''Cortana''': "Good! Step one complete! We have a straight shot into the fusion reactor! We need a catalyst explosion to destabilize the magnetic containment field surrounding the fusion cells. Use an explosive. I recommend a grenade or a [[M19 SSM Rocket Launcher|rocket]]. If you run out of explosives, there is an armory station located near the engine room's entrance."

''The Chief knocks out the first reactor.''

*'''Cortana''': "Analyzing. Fusion reactor number one destabilizing. Use explosives on the other three reactors. That should be enough to trigger a wildcat explosion of the engines."

''The Chief destroys two more reactors, leaving only one left.''

*'''Cortana''': "Keep it up! Only one more fusion reactor to go!"

''The Chief takes out the final reactor.''

*'''Cortana''': "That did it! The engine's gone critical! Based on the current rate of decay, we should have fifteen minutes to get off the ship; we don't have much time! We should move outside and signal for evac. Accessing schematics... there's a service lift at the top of the engine room! It leads to a class-7 service corridor that runs along the ship's dorsal structure. Hurry!"

''The Chief reaches the elevator. A mass of Spec Ops [[Covenant Empire|Covenant]] descends to meet him. He defeats the Covenant and starts the long ride up.''

*'''Cortana (COM)''': "Cortana to [[Echo 419]], come in Echo 419!"

*'''[[Foehammer]] (COM)''': "Roger, Cortana. I read you, 5 by 5."

*'''Cortana (COM)''': "The ''Pillar of Autumn''<nowiki>'</nowiki>s engines are going critical, Foehammer! Request immediate extraction! Approach the crash site and be ready to pick us up at external access Junction 4C as soon as you get my signal!"

*'''Foehammer (COM)''': "Affirmative. Echo 419 going on station."

''A few moments later, still on the elevator.''

*'''Foehammer (COM)''': ''(concerned)'' "Echo 419 to Cortana. Things are gettin' noisy down there. Everything okay?"

*'''Cortana (COM)''': "Negative, negative! We have a wildcat destabilization of the ship's fusion drive core. The engines must have sustained more damage than we thought! ''(Off radio)'' Analyzing... we have six minutes (five minutes if on [[Legendary]] difficulty) before the fusion drives detonate. We need to evac ''now''!"

''The Chief reaches the top of the elevator.''

===Warning: Hitchhikers May Be Escaping Convicts===
*'''Cortana''': "Activating final countdown timer. When it reaches zero, the engines will detonate. The explosion will generate a temperature of almost 100,000,000 degrees. ''Don't'' be here when it blows."

''If the player leaves the [[M12 Force Application Vehicle|Warthog]] station on foot:''

*'''Cortana''': "We can't make it on foot, we need a vehicle!"

''If player is still leaving the station on foot:''

*'''Cortana''': "Alert: We need to keep moving, get back in the Warthog."

''The Chief drives down the corridor. Flood, Covenant, and Sentinels are fighting all around him. Eventually he nears the site where Foehammer is supposed to extract him.''

*'''Cortana (COM)''': "Cortana to Echo 419! Request extraction now, on the double!"

*'''Foehammer (COM)''': "Affirmative, Cortana. Foehammer inbound."

''The Chief arrives at a wide open platform.''

*'''Cortana''': "Wait, stop! This is where Foehammer is coming to pick us up. Hold position here."

''If the player waits for Foehammer:''

''Echo 419 appears around the hull of the ''Pillar of Autumn'', listing badly and flaming at the engines. A pair of Banshees close in on the [[D77-TC Pelican|Pelican]].''

*'''Cortana (COM)''': "Cortana to Echo 419! Two Covenant Banshees are approaching on your six! Evade! Say again, evade!"

''An explosion lurches the Pelican the starboard wing dips, ablaze, and Foehammer yells into the speaker as she passes under the platform.''

*'''Foehammer (COM)''': ''(panicked)'' "I'm hit! Mayday! Mayday! Airfoil structures have been shot to hell! I can't hold her! I can't hold her!"

''Foehammer continues to yell into the speaker, her words becoming inaudible as the roar of the damaged engines are heard in the background. The Pelican flies into the distance, still ablaze, collides into the ''Pillar of Autumn''<nowiki>'</nowiki>s hull and explodes, debris flying everywhere.''

*'''Cortana (COM)''': "Echo 419!...''(off speaker)'' She's gone. Calculating alternate escape route. ''(Timer restarts)'' The ship's inventory shows one [[Longsword]] fighter still docked in [[Launch Bay 7]]. If we move now, we can make it!"

''If the player hurries past the platform, Cortana's message is cut short.''

''If the player enters a maintenance tunnel, he/she will find [[Thirsty Grunt|a lone Covenant soldier]].''

*'''Thirsty Grunt''': "Ugh... Good thing that the food nipple will be waiting for me at the starship, cause man; I worked up a Big, Grunty, Thirst!"

''The Chief comes around the final S-curve in the corridor.''

*'''Cortana''': "Chief, up ahead there's a gap in the trench! At top speed, we should be able to clear it!"

''The Chief clears the gap. As he reaches the bay, heavy fighting between the Covenant and Flood is seen. A Longsword fighter is docked at the end. A barricade forces the Chief to get out of the Warthog and finish the journey on foot.''

'''Cortana''': "That's the ship! ''Move''! We need to get aboard ''now''!"

‘’The Chief runs up the ramp.’’

[http://www.youtube.com/watch?v=nl_gByN6zSw '''{''Cutscene''}''']

''The Chief (with no weapon in hand) makes a break across the platform for the Longsword, the Flood closing in behind him. He makes it through the open door just before them, and slams the hatch closed as he runs through.''

*'''Cortana''': "We're cutting it close!"

''The Chief sprinting for the cockpit, is jarred by an explosion and braces himself against a wall, shaking his head. He reaches the cockpit, jumps into the seat, quickly punches a series of buttons, and takes the controls in his hands.''

*'''John-117''': "Here we go."

''The Longsword rises above the platform slowly, turning to face the open end of the bay, and lights its engines, rocketing away from the exploding ship. Cuts to an exterior view of the ''Pillar of Autumn'', as it burns and explosions flare all along its length. A horde of Flood stumble slowly towards it, and the Longsword arrows from the starboard side of the ship away into the sky view cuts to follow the Longsword, looking back towards the ''Pillar of Autumn'' as the explosions intensify. The Longsword clears the atmosphere, flying away from Halo. The Master Chief stares straight ahead, piloting the fighter as quickly as he can. Cut to a frontal view of the Longsword; as it sweeps past the view, the distant side of Halo is drowned out in a huge light, which grows and grows, and then a massive shock front sweeps through the ring, shattering it into sections. In the cockpit, a screen beeps and displays: "ENGINE TEMP CRITICAL".''

*'''Cortana''': "Shut them down, we'll need them later."

''The Chief flips a few switches and the Longsword's engines die, leaving it drifting. Debris from the blast hurtles past it, still hot and glowing.''

*'''Cortana''': "Fancy a look?"

''The Master Chief rises from his chair and moves to one of the Longsword's windows. Halo has broken into a few dozen large fragments, all of which are slowly spinning away from each other. As the Chief watches, one massive fragment comes swiftly from the far side of the ring and collides with another, closer one, splitting it in half, and the two go spinning off in a giant gout of fire and debris. Silent explosions spread throughout Halo's remains. The ring has been destroyed.''

*'''John-117''': ''(braces himself against the frame of the Longsword cockpit)'' "''(quietly)'' Did anyone else make it?"

*'''Cortana''': "Scanning." ''(Pause)'' "Just ... dust and echoes. We're all that's left."

''The Master Chief shakes his head and moves back to his seat.''

*'''Cortana''': ''(hesitant)'' "We did what we had to do ... for [[Earth]]. An entire Covenant [[Fleet of Particular Justice|armada]] obliterated, and the Flood... we had no choice. Halo ... It's finished."

*'''John-117''': "No...I think we're just getting started."

''The Chief removes his helmet, but the cockpit's frame blocks the view of his head. The view tracks the Longsword for a few a moments, Basis looming large in the background, before panning to focus on a large spiral galaxy hanging in the sky, an ornament emblazoned across the heavens. A few final, dark notes of a cello play, and everything fades.''

''[[Halo: Combat Evolved Credits|Credits]] roll.''

[[File:D40 35.jpg|thumb|Johnson and an Elite.]]

[http://www.youtube.com/watch?v=Pm2a-xxpou0 '''{''Legendary Cutscene''}''']

''(This is only seen when playing The Maw on Legendary difficulty, and is to be considered '''non-canon''' as Sergeant Johnson [[Halo: First Strike|was actually on a Pelican at the time]].)''

''[[Staff Sergeant]] [[Avery Junior Johnson|Johnson]] struggles with an uncloaked Stealth [[Hugging Elite|Elite]] for an Assault Rifle, among a multitude of dead Flood forms with the ''Pillar of Autumn'' in the background. ''

*'''Sergeant Johnson''': "C'mere you motherf-! I'm gonna... Grrr... ah."

''They suddenly stop and turn to see the ship about to explode in the distance.''

*'''Sergeant Johnson''': "Oh shi..."

''Johnson turns to the [[Elite]].''

*'''Sergeant Johnson''': "This is it, baby! ''(affectionately)'' Hold me."

*'''[[Hugging Elite]]''': "...mmf."

''The two embrace as the ship explodes and the Elite additionally places his right hand on Sergeant Johnson's bottom.''

== Trivia ==
===Glitches===
*If one opens the exhaust vent and jump inside it before firing the rocket, the vent will close on the player. The player will take damage and die from the heat. This is easier on co-op when someone else fires the rocket.
*During the Warthog escape on co-op, the weight of the second player manning the turret can cause difficulties making jumps on the large ramps, causing the Warthog to flip over backwards in the air. Having the second player in the passenger seat, however, will keep the Warthog balanced.
*If the player continues driving after the pick up point where Echo 419 is shot down by Banshees, Cortana will say her line even if Foehammer hasn't crashed yet (this is actually a time-saving strategy, but one won't get a checkpoint).
*In the cutscene where the Chief takes off his helmet, he actually has a second helmet on underneath, because [[Bungie]] didn't model a face for him. This can only be seen with the proper modding tools required to alter cutscenes. This was also revealed in the ''[[Halo 3]]'' Legendary Edition bonus disc.

====Mistakes====
*The ''Pillar of Autumn'' is approximately 1.17 km long. This, however, contradicts this level where the player must drive along a 3.5 km long service corridor that supposedly runs the length of the ship. This was probably for generating the tension and atmosphere necessary for the level. However, as Master Chief's route was not straight, the curves and twists would be able to create at least 3km for him to drive. However, nav points indicate the straight distance to the target, and does not count twists and turns. This is proven by when one makes a map using the [[Halo Editing Kit]], make a single player map, and mark a nav point.
*The Banshees that attack and follow Echo 419 have open cockpits so they look like no one is piloting them. The Banshees do not actually fire shots that destroy Echo 419. If the player fires at the Banshees, they will not receive any damage and cannot be destroyed until ''after'' Echo 419 has passed over the extraction point.

====Easter Eggs====
*The [[Thirsty Grunt]] appears in this level at one of the tunnels close to the Longsword Fighter.
*In the level, there is a room under one of the runways that has the word "[[Rex|REX]]" written in [[human]] blood splatters and bullet holes.

===References===
*The definition of a "maw" is "the throat, jaws, and gullet of a flesh-eating animal". This is a possible reference to either the Flood or the adage: "Victory from the jaws of defeat."
*This is the only level that has a time limit in the ''[[Halo]]'' trilogy, although when the [[Warthog Run]] was remade in ''Halo 3'', the player will die if he/she lingers for too long in an area.
*At the beginning cutscene where it shows the ''Pillar of Autumn'' on its side, a [[Marathon]] logo can be seen on either side of the ship, engraved into two large circles just like in the beginning of the game.
*In the beginning cutscene, Master Chief crashes his Banshee into the wall and climbs up into the ship. This is similar to a scene in the ''[[Halo 2]]'' level [[The Oracle]], where the [[Thel 'Vadamee|Arbiter]] crashes a [[Heretic Banshee]] into the wall before climbing it and re-entering the [[Gas Mine]].
*Part of the opening dialog in which Cortana says "We're not going to make it!" which the Chief replies with "We'll make it" is repeated in the end cutscene of the level "Halo" in ''Halo 3''.
*When the player has destroyed the engines, Cortana will say, "It leads to a class [[List of "seven" references in Halo|7]]-service corridor that runs along the ship's dorsal structure."
*It is interesting to note that during the elevator ride Foe Hammer responds to Cortanas transmission with "Roger, Cortana. I read you, 5 by 5.". Five by Five is one of 25 military responses, indicating that radio communications are the best possible. Five by Five in mathematical terms is 5 x 5 which is 25, and 2+5=7.
*During the elevator ride, just before the Warthog run, [[Cortana]] instructs Fohammer to pick the Chief up at "External Access Junction 4-C". Considering that C is the third letter of the alphabet, 4C is another reference to [[List of "seven" references in Halo|7]].
*The final chapter of the level, "Warning: Hitchhikers May Be Escaping Convicts", is referenced in the ''Halo 3'' level [[Tsavo Highway]] as "Warning: Hitchhikers May Have Jetpacks". It's also referenced by [[Vergil]], who repeats the line as "Warning: Hitchhikers may be escaped convicts" in the ''[[Halo 3: ODST]]'' level [[Data Hive]].
*The dialogue of Cortana where she warns the player about the gap in the trench starts when the player is exactly [[List of "seven" references in Halo|700]] meters away from [[Launch Bay 7]].
*What looks like an approaching Flood army in the final cutscene was revealed to be seven Flood forms, in the ''Halo 3'' Legendary Edition DVD cutscene commentary.

===Miscellaneous===
*If one skips the bridge cutscene before the Sentinels shatter the main display, the display will not be shattered when gameplay resumes, and will not shatter no matter how long the Sentinels or the player shoots at it. This can actually be quite advantageous as it provides the player with additional cover when fighting the Sentinels. If the Sentinels kill the player, the glass may reappear when they respawn.
*The Assault Rifles and [[Shotguns]] in the armory have no ammo. The Shotgun ammo is in the green cases near the Rocket Launchers in the second armory adjacent to the engine room. The unloaded weapons in the first armory could be a reference to [[Halo: The Flood]] in which the surviving marine forces returned to the Autumns wreckage to recover most of its ordnance.
*This is the only level in the trilogy that allows the player to enter a ships engine room.
*This is the only level where [[Elite]] [[Combat Forms]] will use [[Active Camouflage]]. They will come in from the locked door in the armory, along with several regular Combat Forms. There will sometimes also be several human Combat Forms that have Active Camouflage activated, although there is no known reason for this. Since feral Flood are non-sentient, it is unlikely that they share equipment. The Elite Combat Forms are referenced as "floodcombat elite stealth unarmed" in the code, and can be seen in HMT, and with the default tagset of the Halo Editing Kit, and states that these are likely infected Stealth Elites.
*This is the only level in the trilogy that countdown timer is used for escape.
*The Special Operations Elite commanding the squad of [[Special Operations Grunt]]s in Maintenance Elevator 07 is actually [[Zuka 'Zamamee]] from [[Halo: The Flood]]. Zuka was pursuing John-117 during almost the entire duration that he was on Installation 04. As a result, he is considered by some as an unofficial mini-boss on the level by fans. Depending on the level of difficulty, however, there can be more than one Spec Ops Elites in the elevator. Unlike in the book Halo: The Flood, Zuka 'Zamamee is not manning a [[Shade Turret]] nor is there one nearby.
*In the chapter called "Warning: Hitchhikers May Be Escaping Convicts" on Legendary, the player has only five minutes before the engines explode. This is different from [[Easy]], [[Normal]], and [[Heroic]] [[Campaign]] modes, which have six minutes.
*When Halo explodes, it sometimes makes the same gurgling noise made by Flood Combat Forms.
*This level's final cutscene is viewable in the beginning of the ''Halo 2'' level [[The Heretic]].
*Apart from the Legendary Ending, the only way one can actually see the ''Pillar of Autumn'' explode is to let the timer run down to zero. A cutscene will show it exploding.
