Cheats: On the main menu, edit the player name to be GOD (all in caps). Then either launch a new campaign or start a saved game. The saved games' player name must also be GOD. This cheat gives you invulnerability. The Player name must be changed to GOD each time the game is run. And a few command line parameter: Start the game with the parameter /KARMA => all weapons and equipment are made available /US => i don't know if this even does anything, but i found it in a list of switches and it's not on the help screen, so maybe.
