, also known as or , is a first-person shooter developed by Treyarch and published by Activision. This is the ninth main installment for the franchise, and was released on November 13, 2012.
New Gameplay Features:Departing from the notorious linear campaign style of past Call of Duty games, Treyarch decided to take a non-linear and sandbox approach to Call of Duty: Black Ops II, (meaning no back-to-back missions with the same outcome every time replayed) instead the old linear style has been dropped in favor of "a more open ended campaign that relies heavily on player choice."
The game continues the story from Black Ops 1 , which saw the return of Alex Mason , Frank Woods , Jason Hudson and Viktor Reznov.
BO2 is set in two time periods 1986 and 2025.
