Black Ops takes place between 1961 and 1968 during the Cold War, 16 years after the events of World at War. It portrays a secret history of CIA clandestine black operations carried out behind enemy lines. Much of the campaign is told through the eyes of SOG and CIA operative Alex Mason, primarily through flashbacks. Mason awakens strapped to a chair in a room filled with monitors, bombarded with questions by two unknown interrogators about a numbers broadcast. Mason then recalls several events from the past in an attempt to answer their questions, setting up the missions of the game.
