Rapture a psychopath's utopia.This is the city where BIOSHOCK is based.It is a very strange city not just because it is at the bottom of the Atlantic ocean but because it's population are not human at least not any more.They once were normal people until ADAM came along.ADAM is a chemical which rearranges your DNA normally given the subject super natural powers but some times some thing goes wrong.When a mistake happens the subject's DNA gets screwed up leaving him mentally and psychically mutated.
