Dead Rising Cheats

Start a new game and hang around the Entrance Plaza BEFORE the zombies break in. Wait for two real-life hours and you will unlock Indoorsman. Continue on with the game and let the zombies break into the mall. Go to the security room and save your game. Shut down your console and start up Dead Rising again. Load the save you just made and you will get a message saying you've unlocked Outdoorsman.
