Redemption

Redemption is the final level in Call of Duty: Black Ops. It is set upon the ship, the Rusalka and sees Mason and Hudson attempt to stop Nova 6 from being unleashed in the USA.

Walkthrough
Redemption opens with a sequence during which the player is a helicopter gunner assisting Weaver's team as he tries to stop the broadcast before the Nova Gas goes off in the US. The Player cripples the ship until Mason's Huey is overwhelmed by three Mi-24, causing the huey to crash near the landing pad, leaving Mason almost off the ship. After climbing up, Mason and Hudson fight through the ship where they find at the bottom level of the Rusalka, learning the source of the numbers were under water, only acessable by a small pool of water surrounding the transmitter in the ship. The player then swims to the underwater station and shuts off the numbers transmission. After, Dragovich is about to shoot Mason when, Hudson distracts him, allowing Mason to pull him down a shaft and drown him.

Ending cutscene
The game ends with Weaver exclaiming its over and then the view goes back to a woman listening to numbers the credits then role depicting the last moments before President Kennedy's death. The view shifts to the crowd gathered around the president's vehicle. The camera zooms in and shows Alex Mason being a part of that crowd.

Trivia

 * After the credits, there is a final non-canon cutscene showing JFK, Nixon, McNamara and Fidel Castro conversing about the Cuban Missile Crisis in the Pentagon. Zombies break through the closed doors and the zombie level, Five, is unlocked.
 * It is heavily implied in this level that Mason killed JFK while Lee Harvey Oswald (historically labeled as JFK's killer) was scapegoated for the murder. During the final fight with Dragovich, Mason says, "You tried to make me kill my president!" To which Dragovich responds, "Tried?!" Also, the ending cutscene shows Mason as part of the crowd moments before the assassination of Kennedy.
