Black Ops 1 Story
Campaign spoilers ahead. Six short beats covering the original 2010 story and its ending.

The numbers in Mason’s head
In 1968, CIA operative Alex Mason wakes strapped to an interrogation chair. His questioners demand the meaning of a mysterious numbers broadcast. The campaign follows his fractured memories, gradually revealing why the numbers matter and who is questioning him.

Cuba, capture and Vorkuta
A 1961 mission to assassinate Fidel Castro kills a double. Mason is captured and handed to Soviet general Nikita Dragovich. In Vorkuta prison, he befriends Viktor Reznov. They lead an uprising; Mason escapes in 1963, but Reznov stays behind.

Nova 6 and an old betrayal
Reznov’s 1945 flashback explains his vendetta: Dragovich, Kravchenko and scientist Friedrich Steiner tested the deadly Nova 6 gas on Soviet soldiers, killing his friend Dimitri Petrenko. Years later, Dragovich plans to use Nova 6 against the United States.

The hunt across Vietnam
Mason, Frank Woods and Joseph Bowman pursue Dragovich’s network through Vietnam and Laos. Bowman is killed; Woods disappears while fighting Kravchenko. Meanwhile, CIA agents Hudson and Weaver trace Nova 6 to Rebirth Island, where Steiner could expose the plot.

The truth about Reznov
Hudson reveals that Mason himself killed Steiner. The Reznov accompanying him after Vorkuta was a hallucination. Dragovich’s brainwashing targeted Kennedy, but Reznov redirected Mason toward revenge on Dragovich, Kravchenko and Steiner. Hudson’s interrogation finally helps Mason identify the broadcast source.

Rusalka and the final question
Mason and Hudson assault the Rusalka and its underwater station. They stop the numbers transmission that would activate Soviet sleeper agents to release Nova 6, and Mason drowns Dragovich. The final Kennedy footage hints at Mason’s involvement in the assassination, without conclusively resolving his role.
