Hints & Tips

Walking corpse
Enter the Health refill code to enable the "Health" on the options menu. Pause the game immediately after dying, and before regenerating. Use the "Health" option to refill the life bar. Your character can now move around as a splattered corpse, totally invulnerable to enemies. However, since your own actions are limited, this trick is of limited value. However, it is an interesting thing to try on level 6 or during a two player game.
