BioShock 2 is a first-person shooter video game developed by 2K Marin and Irrational Games for the Xbox 360 and PlayStation 3 video game consoles, and the Windows (Microsoft Windows) operating system. It is the sequel to the 2007 video game BioShock. The game was released worldwide on February 9, 2010.

The game is set in fictional dystopian city Rapture, in a biopunk, steampunk alternate history 1968, eight years after the events of BioShock. The protagonist and player-controlled character is a Big Daddy (Big Daddy (BioShock)), a being that has had its organs and skin grafted into an atmospheric diving suit. Among the first of its kind, the player-controlled Big Daddy reactivates with no recollection of the past decades events, and scours the city in an attempt to relocate the Little Sister that he was paired with. When it becomes obvious that Raptures leader Sofia Lamb will become responsible for the citys destruction, the Big Daddy attempts to overthrow Lamb and her army of Big Sisters.
