Call of Duty: Black Ops II is a 2012 
first-person shooter video game developed by 
Treyarch and published by 
Activision. It was released for 
PlayStation 3, and 
Xbox 360 on
 November 12, 2012. Black Ops II is the first Call of Duty video game to
 feature branching storylines, in which the player's choice affects both
 the current mission and in turn, the overall course of the story. Known
 as "Strike Force missions", these branching storylines appear during 
the 2025 storyline and feature permanent death. The success or failure 
of these missions can have ramifications for the wider campaign 
storyline. Choosing one of the missions locks out the others unless the 
player begins a fresh campaign.Strike Force missions allow the player to
 control a number of different war assets, such as unmanned aerial 
vehicles, jet fighters and robots. If the player dies in a Strike Force 
mission, the campaign continues recording that loss, as opposed to 
letting the player load a previously saved checkpoint. The player's 
progress in the Strike Force missions may go on to change even the plans
 of the story's antagonist, Raul Menendez. By the end of the game, the 
player may have changed the results of the new Cold War.
