Cheat: God Mode in Nightmare and Trauma Modes
Current Rating: Not Rated
To get god mode into the tougher modes, where cheats are not supposed to be activated, start a game on Insomnia or Daydream difficulty and enter "pkgod" to activate god mode. Then, in the menu, load any game you wish, and god mode will stay on. Also note that this will continue through levels, and will only need to be reactivated again when you quit the came and return.
Note: This cheat works up to v1.2; it has not been tested with higher versions.
