Bioshock was one of the biggest hits of 2007. In a year that saw the release of such great titles as Halo 3 and Call of Duty 4, this is no easy feat. Bioshock 2 has been announced, the trailer was first shown on the PS3 version of Bioshock. The new game, titled Sea of Dreams, is expected to be a prequel and a sequel at the same time. It is not being developed by 2K Boston and will instead be developed by 2K Marin. This is primarily because 2K Boston wants to develop something radically different. As if one sequel wasn’t enough, a second sequel has also been announced and is slated for release at roughly the same time as the Bioshock movie.
