There is cheat on cheatfreak.com. they have unlimited life and health!!!!

I may not be doing this correctly, but absolutely ZERO of the cheats I have found work. To
hell with Touchstone for making such a linear game with no cheats. That makes for NO
replayability as far as I'm concerned, due to the fact that the game is so linear no real
changes will happen. I am going to try to find a way to manipulate the game through the
hard drive, and if that doesn't work, I may just sell this version and buy the PC version.

go to cheats at IGN it is really good wright back if you cant find anything
