The game is expected to see a simultaneous launch on PC, Xbox 360 and PlayStation 3 platforms, but Take-Two's own documentation continues to list the SKUs as “TBA,” leading to speculation that a timed-exclusivity announcement may be on the way. Take-Two was reluctant to comment on this, however, adding only that these dates are considered “tentative” and subject to change.
BioShock 2 is set ten years after the events of the original game and places gamers in the shoes of a Big Daddy – the very first Big Daddy ever made in fact. New enemies arrive in the form of other Big Daddies as well as Big Sisters, and a multiplayer mode will be available for the first time, adding to the game's overall narrative with a prequel set during the fall of Rapture. You can see some of the first gameplay footage of the game here.
