Call of Duty: Black Ops 2 (commonly abbreviated as Black Ops 2) is a first-person shooter video game developed by Treyarch and published by Activision. It was released on November 12, 2012, for Microsoft Windows, PlayStation 3, Wii U, and Xbox 360. The game is the ninth installment in the Call of Duty series and the sequel to 2010’s Call of Duty: Black Ops. Black Ops 2 is set in 2025, ten years after the events of Black Ops, and follows a group of characters as they fight against a terrorist organization known as Cordis Die.
The game’s campaign mode features multiple endings, depending on the player’s choices throughout the game. The best ending is achieved by completing all of the game’s missions on the hardest difficulty setting, and by making all of the “good” choices throughout the game. This ending results in the defeat of Cordis Die and the prevention of a nuclear war.
