BioShock promises an environment where almost anything can be turned into a weapon. Players can also biologically modify their bodies to experiment with different battle techniques, explore unique underwater deco with realistic water effects, and make mature moral decisions within the game according to Take-Two.

We've got our eye on BioShock as an early Game of the Year candidate. Everything about the game -- from the horrifying atmosphere to the taut RPG customizations -- is top of the line. Even the graphics are stunning, possibly the best yet seen on the Xbox 360. Needless to say, BioShock has all the markings of a triple-A game, and should be a top consideration this fall for all first-person shooter fans.
