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
With only hours away from the scheduled Nova 6 gas release in US cities, Hudson leads forces on a heli-borne assault on the Rusalka to stop the broadcast. First, Mason must pilot the Huey gunship to destroy the AA defenses on the ship. Once the air defenses are neutralized, Weaver's team is inserted from the aft heli-pad. As the team attempts to make their way into the ship via entrance at the Rusalka's bow section, Mason and Hudson must provide fire support for the team as they advance through the port side deck. Here, Mason will have to deal with a Mi-24A. The fight cripples Mason's Huey, forcing him to make a crash landing at the heli-pad. Mason and Hudson advance through the starboard deck, dealing with 2 Mi-8 HIPs before making it into the ship.

Once they fight their way to the lower deck, they find the Rusalka is just the surface section, the real Numbers Station is underwater. After ordering Weaver to leave the Rusalka and calling in the Navy to sink it, Hudson and Mason swim to the underwater station and shut off the numbers transmission. After they gruesomely fight their way to the command center, Mason accesses the control console to shut down the broadcast. Dragovich appears and is about to shoot Mason when Hudson distracts him, allowing Mason to pull him down a shaft and drown him.

With Dragovich finally dead, Mason and Hudson escape the crumbling underwater station by swimming to the surface, where they are greeted not only by Weaver but by a large US Navy surface contingent as well. The crisis is averted.

Ending cutscene
thumb|300px|right|The Video seen after the credits The game ends with Weaver exclaiming its over and then the view goes back to a woman recording numbers for transmission by the numbers station. 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. Mason then makes the conclusion that he never killed President Kennedy, as Dragovich commanded him to and implied he did. The next video shows the beginning cutscene of the map "Five"

Trivia

 * In the helicopter piloted by Mason, there is a peace symbol to the left of the players view, a common sign in the 1960's when the game takes place.
 * After the credits, there is a final cutscene showing JFK, Nixon, McNamara and Fidel Castro conversing about the Cuban Missile Crisis in the Pentagon. Zombies break through the closed doors (seen above) 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 during Kennedy's landing at the airport. or that he decided to go the place where he would've killed Kennedy if he was still under Dragovich control (as you can see a completely wide view where he would have made the shot) which, in mental case studies, would also be a reason why he continued to pursue leads leading to him being burnt.
 * The wounds on Mason's wrists that he sustained during his Interrogation are no longer visible, any wound would take more than 7 hours to heal completely.
 * this is one of the only levels where Juggernauts appear (and only time they are mentioned as Juggernauts) in the game


 * As the unlocked intel indicate, Mason didn't recover from his mental condition and by 1978, his decision to chase down a currently-unknown lead resulted in the higher-ups deciding that Mason is "burnt", mentally unstable and a threat to national security, and marked for termination.
 * There is a non-playable character in this mission named Sgt. Pepper. This is a reference to the song/album "Sgt. Pepper's Lonely Hearts Club Band" by The Beatles.
 * At the scene where Weaver says "It's over.", the closest ship on the left side with the hull classification number of "68" could possibly be BB-68 USS Ohio, a Montana-class battleship that would've been the one of the strongest in the world but was never put into production.
 * Jason Hudson's voice actor, Ed Harris, played a starring role in the 1989 film "The Abyss," which also happened to have an underwater base that communicated via a docked tanker ship.
 * Whilst descending to the undersea numbers station a tune very reminiscent to the soundtrack of "Bioshock" can be heard. This is probably a nod to the game as the approach angle is also very similar to the angle that the city of Rapture is first viewed from.
 * While swimming to the surface, the player can see the wreckage of the Rusalka sink to the bottom of the ocean.
 * In the Ending Cutscene,the book by JFK can be seen to the right of the woman saying the number sequences,it is although covered by a small black book but is still recognizable.
 * A Cpl. Lamia can be seen in this mission. He commonly wields a Famas. Mark Lamia is Treyarch's Studio Chief.
 * Near the end of the level, as the broadcast station's walls begin to rupture and leak, the player will encounter a Soviet soldier who charges down a narrow stairway, this soldier is immune to knifing as he runs down the stairs.
 * If you fire the machine gun on your helicopter until you fall out of it, you will keep hearing the noise of the machine gun even when you are under the water and while you are killing Dragovich.
 * On the Xbox version of this level sometimes when you rendezvous with Weaver the level will not continue as scripted. There are a few ways to fix this. Throw a grenade at Weaver and he will try to get away from it. Or just friendly fire someone. It can also occur on the PS3 version.
 * This is only mission that Hudson never wears his shades.
 * There is a weird PS3 glitch in this level where there will be a frozen standing character model near the end of the game.
 * There is a glitch where if you use the last Valkyrie Rockets, you will be stuck with it, forcing you to only be able to use your knife. When you take off your underwater suit off, you won't even be able to use your knife. If this glitch occurs, you can restart the mission, leave the mission, or turn off console.
 * At the end of the level, the player will swim to the surface of the ocean with Hudson, not wearing a mask. In reality, a person could not possibly swim to the surface of the ocean from a quarter - kilometer down. It would not only be an issue of hold breath duration, it would also be an issue of air pressure pushing down on the player.
 * The helicopter sequence at the beginning of this level is totally cut from the wii, starting from the point where Mason and Hudson jump out of the destroyed chopper.
