I got rid of my PS3 a few months ago in favor of the 360. This game runs and looks better on the mighty 360! Framerate and color vibrancy is key for a Hack and Slasher like this. Just do yourself a favor if you can, and buy the 360 version.)
They're built a lot better now, very quiet also. I had a PS3 for 3 years straight and that was the only system I had, so I know the system well. It's just not as good for cross platform games like the 360 is, and don't forget, they don't have HALO!
