Cybernoid





 CHEAT MODE:



 Type in 'RAISTLIN' on the title screen and then hit the [Spacebar]

 for infinite lives. You can now also press [N] during the game to

 advance to the next level.



 If the above method fails to work then try the one below.

 Define your keys as Y X E S (sexy backwards) for unlimited lives.

Alternative Cheat:
Type "MELLIE" on the difficulty selection screen (1-3) - the screen will flash briefly to confirm. Play normally and when you die, answer the "play again?" prompt with N - the next level will load anyway.
