The storyline of Call of Duty: Black Ops - Cold War is a stand-alone story that does not require knowledge of the previous games. However, the game features characters familiar to fans of the series, such as Mason, Woods, and Hudson, and joined by a previously unknown CIA agent, Russel Adler.
As the title suggests, the game is set in the Cold War era; during the game, we'll face an enigmatic KGB agent known by the code name Perseus. Interestingly, the game has several endings – which one we actually see at the end depends on the decisions we make during the course of the game.
