The future storyline of Call of Duty: Black Ops II is set in 2025.
The campaign uses two connected timelines. One follows Alex Mason and Frank Woods during the late 1980s, while the principal futuristic storyline follows Mason’s son, David “Section” Mason, in 2025. That later period imagines a new Cold War shaped by autonomous drones, cyberwarfare, and advanced military technology.
Raul Menendez is the central antagonist of the 2025 plot. His Cordis Die movement exploits global resentment and eventually attempts to seize control of the United States’ drone forces. The game’s branching missions and endings mean some details vary according to player choices, but the year of the future arc remains 2025.
A common mix-up is treating Black Ops II as entirely futuristic. Its campaign begins in the 1980s and repeatedly moves between that era and 2025; the question’s wording correctly identifies the future storyline rather than the whole campaign.
