GUNVALKYRIE 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.
GUNVALKYRIE has no button cheats or passwords on Xbox. Its one real unlockable is Challenge Mode.
Challenge Mode: Complete the game once to unlock Challenge Mode, which lets you replay any level you have already cleared.
