''View flies through a canyon filled with pools of reactor coolant under the ''[[Truth and Reconciliation]]''. The {{Pattern|Ket|battlecruiser}} is resting on the top of the canyon, heavily damaged. The [[Flood]] and [[Covenant Empire|Covenant]] forces are fighting all throughout the region.''

*'''[[Cortana]]''': "The [[proselytization network|Covenant network]] is in absolute chaos! From what I've been able to piece together, [[Thel 'Vadam|their leadership]] ordered all ships to abandon [[Installation 04|Halo]] when they found the Flood, but they were too late. The Flood overwhelmed this cruiser and disabled it. The Covenant are terrified the Flood will repair the ship and use it to escape from Halo. They've sent in a strike team to neutralize the Flood and repair the ship for immediate departure. I've got a good lock on [[Captain (Navy)|Captain]] [[Jacob Keyes|Keyes]]' [[Command neural interface|CNI]] transponder signal! He's alive! And the implants are intact! There's some interference from the cruiser's damaged reactor. I'll bring us in as close as I can."

''A group of Sangheili hold the center of the shuttle bay, using a [[Mamua'uda-pattern Shade|Shade turret]] to provide supporting fire while a single [[Mgalekgolo]] and other Covenant troops fight the Flood in the corridors. The Chief ascends through the corridors and reaches the third floor.''

''She assigns another navigation point. A [[Dextro Xur-pattern Spirit|Spirit dropship]] enters the open shuttle bay doors and disperses a group of [[Covenant Special Operations|black-armored Covenant soldiers]] in the lowest area of the bay. The Chief battles through more Flood guarding the open door that the navigation point directs him to.  Killing all hostiles, the Chief follows the navigation point, venturing deeper into the chaotic hallways.''

''The Chief, after fighting through Covenant Special Operations troops and Flood forms, eventually reaches the lowest level of the shuttle bay and steals one of the Banshees. (Alternatively, the Chief can just jump off of the upper level and skip most of the fighting.)''

*It is possible skip the overwhelming majority of the level and get directly to the bridge where the Proto-Gravemind is via a trick commonly known as the "Shield Bump," or less commonly referred to as "the Plasma Wall Spawn glitch." It is performed by overloading the [[Covenant portable shield|portable shield]] in the beginning of the level and then standing on top of it; with perfect alignment the shield will bump the player up and out of bounds such that with careful movement they can make a few jumps and ultimately hop into the room. The level cannot be continued unless one backtracks towards the hallway that would normally come up from the hanger bay (right by the same hallway where the level starts and gets a checkpoint.)<ref>https://www.youtube.com/watch?v=rrLeov8tq5M</ref>

**Alternatively one can use a different glitch known as the "Flood Bump" to use a reviving combat form (ideally the one chasing the Grunt at the start) to push the player through the wall behind them at the very start of the level. Both of these glitches are utilized by speedrunners and can be used to net the Scuty Bump achievement.

*If analyzed, the route the Chief took in the beginning of the level is wrong. Since players can see the bridge through the grille in the beginning of the level, it indicates that the player is on the third floor. However, once the player reaches the hole created by coolant, they are located on first floor of the shuttle bay. The corridors that lead the player from the beginning of the level to the hole are obviously too short to travel such a high and long distance. This is obviously an oversight by [[Bungie]]'s mission designer.

**Both the actor Master Chief and the player can be killed by enemies during the cutscene. If the actor is killed he will die normally and drop all of of his weapons just like the player and most other AIs but the cutscene itself will still continue playing. A static "ghost" Chief with an assault rifle will appear as Cortana talks about how there are no human life signs detected which will change to an upright weaponless ghost during the portion where the Chief punches through Keyes' skull. The body dead body will remain even after the cutscene is over and the player can even pick up any of the weapons dropped. However if the actual player is killed during the cutscene, the game will revert to the last checkpoint mid cutscene. Unlike normal reverts the options to restart the level and revert to the last checkpoint will be missing from the pause menu and only be restored when the player triggers the cutscene again and it plays without the player dying. The other options such as "Save and quit" will still function as normal however.
