All Working Descent Cheats - PC

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. The cheat status will also be included with any games saved and may not be disabled.
