Menace


 CHEAT MODE:

 This one's a bit tricky. Type in 'XR31TURBONUTTERBASTARD' while the game
 is in progress. Try doing that without getting killed off!
 Now press keys [1] to [6] on the numeric keypad to go to the respective
 level, [Help] to replenish weapons and [Return] to go to the end of
 level guardian.
