Black Ops

Call of Duty: Black Ops is a series of Call of Duty games developed by Treyarch. The series began in 2008 with Call of Duty: World at War, which acted as a prologue to the series, and there have been a further five games since.  Along with the change in development studios, the Black Ops series also differentiates itself from the other Call of Duty games by having a separate timeline, different weapons, and covert operation missions.
