Scooby-Doo: Mystery Mayhem 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.

Opening the bridge: On Episode 2 there are four switches controlling the bridge. Press switches 1, 2 and 4 to open it.
Weird Wild West safe code: The safe in the bank takes a three-digit code. Enter 1-3-7, which is written on the blackboard in the schoolhouse.
Busting Fred out of jail: In the alley opposite the jail, have Scooby crawl under the fence to grab the liquid soap, then use it on the gold cart blocking the hole in the jail wall so it slides away.
Hi-Tech Terror red access card: Clear the first three mists, then check the lockers until one opens with the red access card inside. Bring the robot over to the red card door to open it, then turn off all the knobs inside to clear the steam blocking your path.
