there are 2 versions of the game the first one which you cant buy in the stores anymore is way better/bloodier. the original got pulled from the shelves only 7 hours after its release because of parents going apeshit when they saw the game. they re-releaed an edited version for retail stores like two weeks later and from what i understand you can still get the original online if you can find it. one of my friends got the original the only day it was out, it is fucken badass.
