Call of Duty: Black Ops is a 2010 first-person shooter game developed by Treyarch and published by Activision. The game is set in the Cold War era. Much of the Call of Duty: Black Ops 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. #CallOfDuty #BlackOps #Gameplay #Walkthrough
