Without Warning 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.
Without Warning has a single cheat that opens up a hidden pause-menu toolkit.
Cheat mode: Press X, Y, B, L, Left, Up, Right, R at the main menu. A sound confirms correct entry, and pausing during play then reveals an FMV viewer, level selection and level skip options.
