Scooby-Doo! Unmasked Cheats
How to use these cheats
Button names refer to the Xbox controller — A, B, X, Y, the LB/RB bumpers, LT/RT triggers and the D-pad. Unless told otherwise, enter codes from the pause or options menu, or while playing. Some cheats disable achievements for that save — keep a separate save before you start.
Scooby-Doo! Unmasked on Xbox has very little in the way of cheats: one real button code for extra Mubber and a simple trick for the Bat costume.
100 extra Mubber: During gameplay hold L, then quickly press X, Y, X, A.
Bat costume: Fly as high as you can, then press B.
Mubber: Mubber is the game's currency for buying and upgrading Scooby's costumes, so repeat the code whenever you need a new suit for the next level's gimmicks.
