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 [[Covenant battle 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 {{Class|CCS|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.

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.''

''Two Betrayals'' was primarily designed by [[Bungie]] designer [[Dan Orzulak]] but it was eventually given to fellow designer [[Tyson Green]].{{Ref/YouTube|Id=IGN|9ndZbg8Mr-Q|IGN|Halo: Combat Evolved Devs React to Speedrun (Martin O’Donnell, Marcus Lehto)}} ''Two Betrayals'' shares most of its level geometry with ''[[Assault on the Control Room]]'', albeit adding the phase pulse generator rooms and skipping the opening section of ''Assault on the Control Room'': from where ''[[Echo 419]]'' deploys John-117 to where he first finds members of [[Fireteam Zulu]].
{{Main|Development of Halo: Combat Evolved}}
''Two Betrayals'' was primarily designed by [[Bungie]] designer [[Dan Orzulak]].{{Ref/YouTube|Id=IGN|9ndZbg8Mr-Q|IGN|Halo: Combat Evolved Devs React to Speedrun (Martin O’Donnell, Marcus Lehto)}} ''Two Betrayals'' shares most of its level geometry with ''[[Assault on the Control Room]]'', albeit adding the phase pulse generator rooms and skipping the opening section of ''Assault on the Control Room'': from where ''[[Echo 419]]'' deploys John-117 to where he first finds members of [[Fireteam Zulu]]. The other main differences from ''Assault on the Control Room'' are that John-117 works "backwards" through the level (aside from his detours in Banshees), and it occurs at night.


Cortana says British phrases like 'sod off' and 'toady about' in the opening cinematic of the level, because [[Jason Jones]] originally wanted Cortana to have a British accent. Cortana's voice actress [[Jen Taylor]] had already recorded the lines in her natural American accent when [[Joseph Staten]] raised the issue to Audio Director [[Martin O'Donnell]]. The dialogue and American accent were kept in the final release due to time constraints.{{Ref/Film|Id=Commentary|[[Halo 3 Legendary Edition|''Halo 3'' Legendary Edition]], Halo: Combat Evolved developer commentary}} In ''[[Halo: The Flood]]'', Cortana says "piss off" rather than "sod off".
In an early story draft, John-117 returned to the Control Room to find Cortana had gone mad with power and now wanted to take over the universe. This plot point was cut for unspecified reasons. Cortana says British phrases like 'sod off' and 'toady about' in the opening cinematic of the level, because [[Jason Jones]] originally wanted Cortana to have a British accent.

343 Guilty Spark's dialogue "''Last time you asked me if it were my choice, would I do it?''" was a mystery for 12 years until the release of the novel ''[[Halo: Silentium]]'', which reveals that 343 Guilty Spark was referring to a question asked by the [[IsoDidact]] before 343 Guilty Spark was assigned to Installation 04, which was: "''Tell me [[Chakas]], if it was your choice, after all we have seen and survived... would you fire the rings?''"{{Ref/Novel|Halo: Silentium|Page=314}} This revelation provides context for many of 343 Guilty Spark's cryptic comments to John-117, in which he addresses the Master Chief as if they had met before and presumes the Spartan to be fully aware of protocol; it can be inferred that Spark somehow believed John to be the IsoDidact.
343 Guilty Spark's dialogue "''Last time you asked me if it were my choice, would I do it?''" was a mystery for 12 years until the release of the novel ''[[Halo: Silentium]]'', the third and final novel of the [[The Forerunner Saga]], which reveals that 343 Guilty Spark was referring to a question asked by the [[IsoDidact]] before 343 Guilty Spark was assigned to Installation 04, which was: "''Tell me [[Chakas]], if it was your choice, after all we have seen and survived... would you fire the rings?''"{{Ref/Novel|Halo: Silentium|Page=314}} This revelation provides context for many of 343 Guilty Spark's cryptic comments to John-117, in which he addresses the Master Chief as if they had met before and presumes the Spartan to be fully aware of protocol; it can be inferred that Spark somehow believed John to be the IsoDidact.


The events of this level occurs concurrently with the ''[[Halo: Fireteam Raven]]'' level ''[[Ice Canyon]]'', which at one point take places at the canyon where John-117 finds the Banshee to reach the final phase pulse generator. John-117 makes a brief cameo on ''Ice Canyon'', in which he uses an M90 shotgun to kill a [[Flood tank form]] that was charging at [[Fireteam Raven]]. He then nods at the ODSTs before leaving them.

Line 297: Line 300:
*After the player takes out the third generator, any remaining Sentinels in the room will be destroyed. However, in rare instances that the generator is destroyed and the Aggressors are left alive, they will begin attacking the Master Chief and, despite being in a scripted custom animation, the Chief's shields will fall and he will die. The dialogue continues regardless.

* In the PC version of the game, Cortana does not shift colors during the beginning cinematic, instead she only appears green. Due to ''Halo: Combat Evolved Anniversary'' being built using the PC version, this error is retained in the game's original graphics.

* It's possible to soft lock the mission if the player manages to bring either a Ghost or Banshee with them into the large room just before heading towards the final generator. This can be done if the player, with enough practice, manages to jam either vessel through the semi-operational blastdoor used to enter the room. As a result, the 'Final Run' chapter won't activate, as well as any waves of Covenant or Flood that were meant to spawn.

*Cortana says she can't "even begin to calculate the pulse's range," however, 343 Guilty Spark already stated that Halo's maximum range is 25,000 light years. It is possible that she just means she can't confirm the Monitor's statement.

*One can snipe the [[Type-26 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.

*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.

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".
