BioShock takes place in the early 1960's where your player character finds himself in the middle of the ocean, the victim of an apparent airplane crash. Through a series of events your character finds himself going underwater and finding an undersea complex called Rapture, which was set up in the 1940s as a kind of utopian complex that failed. BioShock takes place mostly in Rapture as you deal with and fight with its citizens, and the RPG aspect comes into play as your character has abilities upgraded by Plasmids, including upgrades to weapons, psi powers and even a crafting system where the player can create new weapons and items.. The game is due out for the PC and Xbox 360 (and maybe the PS3) in 2007.
