We are still waiting to find out what in the wide, wide world of sports Irrational Games plans to do for its next game project. For the moment, though, we will have to be content with the developer's official web site offering us some unreleased concepts from its last game, the original Bioshock.

These splicers are decidedly weird looking and have names like Yam Hand and Jelly Man. We especially like Monster Bug, described as a "huge insect slowly growing from within a human being and taking over the physical form." Supposedly this particular creature concept helped to sell Bioshock to prospective publishers but it never made it in the final game. Pity.
