'''Two Betrayals''' is the eighth [[campaign]] level in ''[[Halo: Combat Evolved]]''. This is the last level in which [[Kig-Yar|Jackals]] are fought. It is also the first level where [[Sentinel]]s are hostile enemies instead of your allies.

The Master Chief, after teleporting back to the [[Control Room]], proceeds to activate [[Installation 04]]. However, [[Cortana]], who after spending twelve hours in the control room has discovered Halo's true purpose, stops him just in time. After stealing the [[Activation Index]], she tells the Chief that Halo will wipe out all life in the galaxy, and turns the Chief against the [[343 Guilty Spark|Monitor]] who confirms Cortana's claims, confused that the Master Chief didn't already know this. Spark sends [[Sentinel]]s to take the Spartan's head, and the [[Artificial intelligence|AI]] inside his helmet, but they are quickly destroyed.

 

Cortana decides that they must destroy Halo to keep it from being fired and decides that the best course of action is to detonate the {{UNSCShip|Pillar of Autumn}}'s fusion engines which will destabilize the ring and cut through a number of primary systems. To buy them some time in case the Monitor finds another way to activate Halo, Cortana orders the Master Chief to disable the three [[phase pulse generator]]s in the area to force the Monitor to make repairs before Halo can be fired. The Master Chief is forced to fight through a combination of Covenant, Flood and Sentinel forces and use [[Type-26 Banshee|Banshees]] to reach each generator which Cortana uses an [[EMP]] to disable. Cortana is able to use the [[proselytization network|Covenant battlenet]] to locate the ''Pillar of Autumn's'' crash site, but requires Captain [[Jacob Keyes]] or his command codes to activate the ship's [[self-destruct]]. After disabling the third pulse generator, Cortana is able to locate Keyes, who is still alive, onboard the Covenant {{Pattern|Ket|battlecruiser}} ''[[Truth and Reconciliation]]''. At Cortana's suggestion, the Master Chief allows the AI to draw power from his suit to use Halo's [[teleportation grid]] to teleport them to the battlecruiser rather than calling for a ride which will take more time that they don't have.

*'''Cortana''': (''Sarcastically)'' "Oh! I didn't realize. He's your ''pal'', is he? Your ''chum''? ''(angrily) ''Do you have any idea what that ''bastard'' almost made you do?!"

*'''John-117''': "Yes... Activate [[Installation 04|Halo]]'s defenses and destroy the [[Flood]], which is why we brought the Index to the Control Center."

*'''343 Guilty Spark''': "How... how... how ''dare'' you?! I'll-"

*'''Cortana''': "Do what? ''I'' have the Index! You can just float and ''sputter!''"

*'''Cortana''': "You have ''no idea'' how this ring works, do you? Why the [[Forerunner]]s built it? Halo doesn't ''kill'' Flood, it kills their ''food''. [[Human]]s, [[Covenant Empire|Covenant]], whatever. We're ''all'' equally edible! The only way to stop the Flood is to ''starve'' them to death. And that's exactly what Halo is designed to do: Wipe the galaxy clean of all sentient life. You don't believe me? Ask ''him''!"  

[[File:GuiltySparkAnniversary.png|thumb|300px|343 Guilty Spark threatens the Chief with his Sentinels.]]

*'''Cortana''': "We can't let [[343 Guilty Spark|the Monitor]] activate Halo. We have to stop him - we have to ''destroy'' Halo. According to my analysis of the available data, I believe the best course of action is somewhat... risky. An explosion of sufficient size will help destabilize the ring, and will cut through a number of primary systems. We need to trigger a detonation on a large scale, however. A starship's fusion reactors going critical would do the job. I'm going to search what's left of the Covenant [[proselytization network|battlenet]], and see if I can locate the ''[[UNSC Pillar of Autumn|Pillar of Autumn]]''<nowiki>'</nowiki>s crash site. If the ship's [[fusion reactor]]s are still relatively intact, we can use them to destroy Halo."

*'''Cortana''': "I haven't located the crash site yet but we need to buy some time, in case the Monitor or his Sentinels find a way to activate Halo's final weapon, without the Index. The machinery in these canyons are Halo's primary firing mechanisms. They consist of three phase pulse generators that amplify Halo's signal, and allow it to fire deep into space. The power levels are enormous. I can't even begin to calculate the pulse's range. So, if we damage or destroy these generators, the Monitor will need to repair them before Halo can be used. That should buy us some time. I'm marking the location of the nearest pulse generator with a [[navigation point|nav point]]. We need to move in and neutralize the device."

*'''Cortana''': "Wait. We should commandeer one of those [[Type-26 Banshee|Banshees]]; we'll need it to reach the pulse generator in time."

''A [[Sangheili]] enters a [[Zurdo-pattern Wraith|Wraith]] and bombards the Chief's position. The Chief destroys the armor and the troops in the area. He commandeers the Banshee fighter.''

*'''Cortana''': "That's the pulse generator. The center core is the signal amplifier. That's what we need to shut down. We need to interrupt the pulse generator's energy stream. I've adjusted your shield system so that it will deliver an [[electromagnetic pulse|EMP]] burst to disrupt the generator, but you'll need to walk into the beam to trigger it. The EMP blast should neutralize the generator. But it will also drain your shields and leave you vulnerable until they recharge."

''The Chief steps into the generator. The ground shakes rapidly as a small explosion drains the Chief's [[energy shielding|energy shields]].''

''After fighting through Covenant troops, the Chief sees a few Flood combat forms attacking more Covenant patrols. The Spartan fights his way across several bridges that he [[Assault on the Control Room|previously traversed]] on his way to the Control Room. Various Covenant soldiers, including a [[Sangheili Zealot]], attempt to repulse overwhelming numbers of Flood. The Chief kills them all and eventually makes his way to the bottom of the canyon.''

''A large Covenant force defends the area, including a Wraith tank, several [[Mamua'uda-pattern Shade|Shades]] and numerous infantry.  The Chief manages to kill them all and leaves the area.  Proceeding past the area where a [[M12 Warthog|Warthog]] lies overturned, the Spartan continues to the next area where he fights through another large contingent of Covenant forces, including another Wraith and two [[Mgalekgolo]]. Eventually the Chief is able to defeat all hostiles present, allowing him to commandeer a Banshee.  The Chief uses the fighter to wipe out several [[Unggoy]] operated Shade turrets as well as several [[unidentified fuel rod gun|fuel rod gun]] wielders and their Sangheili Zealot commander.''

''If the player continues on toward the third canyon before disabling the second pulse generator:''

''The Chief witnesses a group of Covenant led by two Sangheili Zealots making a stand on a hill against hugely overwhelming numbers of Flood. Eliminating the survivors, the Chief exits into another valley where yet another battle is taking place.  A nearby cave opening hosts a large supply of abandoned UNSC weapons and ammunition, allowing the Spartan the opportunity to resupply. Eventually the Chief enters a final valley where a group of Flood throw themselves at a mass of Covenant defenses, including two Wraith tanks, several Shade turrets and a large number of assorted infantry being commanded by a Sangheili Zealot. Later in the battle, a squad of [[Stealth Sangheili]] as well as another Zealot, a [[Mgalekgolo]] pair and more infantry emerge. After a protracted battle, the Chief is able to kill all foes in the area and enter a Banshee fighter. He flies to the platform that leads to the third generator. Sentinel Aggressors appear and fire at him. As he arrives at the room containing the third generator, Aggressors with energy shielding appear. He eliminates the Aggressors and disables the final generator.''

*About halfway through the level, one will come across a room where when one first opens the door and a dead Sangheili Ultra and a dead Minor Unggoy with Pod infectors on them can be seen. If the player fires his/her weapon near them, they will jump from the bodies and start attacking the player.

===Easter eggs===

*In ''Halo: Combat Evolved Anniversary'', the eighth [[Terminal (Halo: Combat Evolved Anniversary)|terminal]] can be found in the Control Room, directly across from the central console.

*The [[Halo: Combat Evolved Anniversary skulls#Piñata skull|Piñata skull]] in ''Anniversary'' can be found over the tunnel's entrance, which is directly opposite of the platform that leads to the third generator.

*In the beginning cutscene, Master Chief is holding an MA5B Assault Rifle, but when the gameplay begins, the player instead will start with an M90 shotgun and a Plasma Pistol.

*One can snipe the [[Zurdo-pattern Wraith|Wraith]] driver at the beginning of the level. When the [[Rock Anthem for Saving the World|soundtrack]] starts, aim at the Wraith and one will see a Sangheili. The player still can't drive the Wraith, but this trick can help favourably in Legendary.

*There are a few upturned vehicles scattered around that have dead Flood combat forms beside them, implying that they drove them, even though they cannot drive vehicles in ''[[Halo: Combat Evolved]]''.

*In ''Anniversary'' graphics, all Unggoy Majors in this level who wield fuel rod guns wear red-colored Special Operations Unggoy masks.

*In the ''[[Halo 2]]'' level ''[[The Heretic]]'' [[Unidentified master gunnery sergeant|an unnamed gunnery sergeant]] discusses the damage done to the Master Chief's old armor as he equips the Master Chief with a new one. Included is damage to the power supply. In the ending of this level and the accompanying scene in ''[[Halo: The Flood]]'', [[Cortana]] mentions possible damage to the suit from using it to power a teleport jump. This level is thus likely where that damage occurred.

*Like ''[[Assault on the Control Room]]'', this level has playable Banshees. However, unlike ''Assault on the Control Room'', using the Banshees is not optional as they are required to reach the mission objectives.

* In the final room of the structures connected to the second pair of bridges, there are nothing but Human Combat Forms roaming the room. It is theorized that Fireteam Zulu, who were stationed in the same vicinity for evacuation, were infected by the Flood in between the events of "Assault on the Control Room" and "The Library".
