Black Ops 2 Campaign Mission Odysseus Gameplay

"Menendez, successfully captured during the Yemen assault, is brought on board the USS Barack Obama for immediate interrogation."
— Mission description

"Odysseus" is the ninth mission in Call of Duty: Black Ops II that takes place on the U.S.S. Barack Obama. After capturing Raul Menendez, the ship comes under attack.

The level is preceded by a short cutscene on the deck of the Obama between Admiral Briggs and David Petraeus. The direction of this cutscene depends on the player's actions in the Strike Force missions. If they were all successfully completed (with the exception of Second Chance), the two will converse fondly about the recently developed alliance between China and the U.S. If the Strike Force missions were not all completed, then the conversation will be more sour and the Secretary of Defence will order DEFCON 3 due to China now being armed against the U.S. Regardless, the cutscene will end with the arrival of Mason and the captured Menendez.

Odyessus opens with Menendez being interrogated by Salazar, before requesting to speak only with Mason, who then enters the interrogation room. The two converse briefly but Briggs interrupts Mason with news that the Obama is under attack by enemy drones. This leads to Menendez holding Salazar hostage and knocking Mason unconscious.

Mason is awoken by Salazar, who informs him that Menendez has escaped. Mason then fights his way throughout the contested Obama, fighting against invading mercenaries and the ship's own automated defense system, whilst communicating with Briggs, who suggests rebooting the ship's system. Salazar moves to Briggs' location, while Mason finds out that rebooting will allow Menendez access to the server room, but is unable to inform Briggs before the Admiral allows the operation to happen. If Harper's alive, he'll inform Section of the Jet Wings assault on the Obama and clear some PMCs using Jet Wings to board the Obama. He'll also take control of auto turrets to assist Section while proceeding to the bridge.

Server Room confrontation
At this point, several potential outcomes can happen as a result of the player's action in the previous missions Karma, Achilles' Veil and potentially Second Chance.

The player shifts control from Mason to Menendez, standing outside the server room with DeFalco, if he survived the events of Karma, or a random mercenary if he did not. Menendez enters the server room and takes Briggs hostage. Salazar, who is revealed to have been working with Menendez then opens fire on the sailors and potentially others depending the player's actions:
