BioShock, one of the biggest contenders for the game of the year award, has surpassed the 2 million copies sold mark, a feat only the fewest games manage to reach. Take Two recently opened 2K Marin, which are rumored to be working on a sequel.

2K Boston, the original developers, are working on a completely new game, so it’s safe to say that the guys at 2K Marin are responsible for the sequel of one of the best shooters ever. Quite a challenge.
