Plot
The mission begins with Menendez being interrogated, while speaking to David Mason. As the interrogation continues, Admiral Briggs reports that enemy drones are attacking the Obama. Menendez is freed by Salazar (without David knowing), knocks out David and Salazar, and then escapes. The player must make his way through the level, at a part of the mission, into the security room. Believing that there is only one option left, Admiral Briggs reboots the sytem, which unfortunately shuts down the security, allowing Menendez to break through. The player then plays as Menendez and goes into the server room, and holds Briggs hostage. As he walks into the control room, threatening the soldiers that he will kill Briggs if his demands are not followed. As Briggs tells the soldiers and Salazar to shoot Menendez, Salazar then betrays them by killing the two soldiers, and either Chloe (Karma) or Farid (depending on the choice in the previous mission). If DeFalco is still alive he will grab Chloe and slit her throat. Then Menendez must make the choice as to whether to shoot Briggs in the head or leg. Menendez then hacks the U.S. command network and takes control of the entire U.S. miltary drone fleet. If Admrial Briggs is killed then he cannot reactivate the ships' defences, leaving them to sink. If he lives, the ships' defences will come back online and the ship is saved. After Section breaks in through the vent, he will check on the wounded and see what Menendez has done. Mason alerts the ship crew that Salazar is a traitor and soon he is captured by friendly forces. After Mason catches up he will interrogate Salazar and when finished will either be taken prisoner or if Harper is still alive, executed. Then, as Mason and Harper reach the upper deck, they run into more enemy forces, and eventually get into one of their jets, where Crosby is waiting. As they take off, Crosby is shot in the arm by a Merc soldier, who is killed by Harper. (If he survived Achillie's Veil. If not the merc will be killed by Section.)

Trivia

 * This mission can have various outcomes (as well as having the most out of any other mission).
 * This mission is the only mission where the player won't start with the weapons they picked/customized prior to it, but these weapons are available in a weapons cache.
 * If the player decided to kill Harper in "Achilles' Veil", Farid will appear on the Obama, but will still be killed. The way Farid is killed depends on whether Karma was rescued or not and how she was rescued. If she was rescued in "Karma", Salazar will try to shoot Karma, but Farid jumps in front of her to take the shot, Karma will then attempt to disarm Salazar, who in return knocks her unconscious, but not kill her. If Karma was rescued in "Second Chance", after Salazar kills the two soldiers, DeFalco will knock Karma unconscious. Farid will then take his own gun out and kill DeFalco by shooting him from behind, Salazar will then kill Farid. If Karma wasn't rescued in either "Karma" or "Second Chance", DeFalco will live and appear on the Obama. After Salazar kills the two soldiers, Farid will quickly take his gun and shoot DeFalco, who kills Farid just before his own death. DeFalco will only appear if he wasn't killed in "Karma"
 * Karma's fate depends on whether she was rescued or not, as well as whether Farid was alive or not. Karma may only live if Farid survived "Achille's Veil". If she was rescued in "Karma", but Farid was killed in "Achille's Veil", after Salazar kills the two soldiers, he will aim his gun at Karma, who surrenders herself, but Salazar still decides to kill her. If Karma was rescued in "Second Chance", after Salazar kills the two soldiers, DeFalco will grab Karma from behind then slice her throat open with a knife, killing her. If Karma is not rescued in "Karma" and "Second Chance", she will remain in captivity. She will survive but will not appear again in campaign.
 * Salazar's Fate depends on whether or not Harper was killed in "Achille's Veil", if Harper was killed, then Salazar is simply taken into custody. If Harper wasn't killed, he will execute Salazar.
 * If Salazar was executed by Harper, aiming the crosshair on his body will display his name as if he was still alive. Shooting or knifing Salazar's body will result in mission failure, ironically displaying "Friendly fire will not be tolerated!".
 * Another outcome in this mission is the alliance with the US and China. If all the Strike Force missions were completed before this mission, then the SDC will ally with JSOC and assist in the protecting the Obama. However, in order to prevent the Obama from being destroyed, Briggs must be wounded, not killed.
 * If Harper executes Salazar, an M27 will appear hovering in the air just to the player's left once the scene has concluded.
 * Just during the beginning of the mission, the player can go into the right hallway and open the first door into Mason's room. Inside, there is a small piece of paper, which has the poem Ulysses written on it, lying on the table. Grabbing the paper will complete a challenge. The poem may have been written by and given to Mason from Menendez
 * If DeFalco is killed earlier in the game, a Mercenary will take his place and proceed in the same role.
 * If DeFalco is in this mission, the line that he says will be in subtitles. However, if Mercenary is instead of DeFalco, and while he speaks, the line will not be in subtitles.
 * The Mercenary's rank may vary. The lowest rank seems to be Private.
 * The briefing room seen during the Strike Force mission cutscenes can be found in this level.
 * During the opening cutscene, when Menendez gets out of the VTOL, "Chasing a Ghost", a track from Black Ops II OST, can be heard.
