2K has released the launch trailer for the first episode in the Burial at Sea DLC for Bioshock Infinite, which is now available for Xbox 360, PlayStation 3 and PC.
This is the first of a two part story DLC for Infinite, which takes players back the underwater city of Rapture from the original Bioshock. Booker and Elizabeth (our protagonists from Bioshock Infinite) also return, however they are noticeably different and both have alternate motivations from the characters we originally met in original Bioshock Infinite.
