Cheat mode:
Type gabbagabbahey to enable cheat mode. Note: The 3Dfx version does not require this code; all cheats may be immediately entered. Type one of the following codes to activate the corresponding cheat function. Note: To prevent self-destruction, re-map the bomb key to avoid conflicts with code entry. Enabling cheat mode will reset your score to 0 unless a new game is started; and may not be used during a multiplayer game.
