Call Of Duty: Black Ops: Declassified (PS Vita)
Before the future could be won, history had to be written. Exposing that story exclusively on PlayStation Vita, Call of Duty: Black Ops Declassified explores original fiction in the Call of Duty Black Ops universe with an all-new campaign of Special Ops missions. Optimized for gamers on-the-go, Call of Duty Black Ops: Declassified delivers the most intense handheld Call of Duty experience to date, including both Special Ops Story mode and Multiplayer combat tailored for the PS Vita.
