Successfully complete the first mission. Pause the game, and select the "Input Code" option. Then, enter one of the following codes to activate the corresponding cheat function. Alternately, successfully complete the first mission. After gaining access to the Rogue Shadow, you will have the ability enable cheat codes. While on board your ship between missions, select "Extras", then the "Enter Code" option. Enter one of the following codes to activate the corresponding cheat function.
Note: Enabling a costume code may prevent some intermissions sequences from being viewed. The game cannot be saved and some achievements cannot be earned when non-costume codes are enabled. To bypass this, reach a checkpoint in a new area after enabling the code(s), then intentionally die, exit to the main menu, and select "Continue". Manually save your game, then quit to the Xbox 360 Dashboard. Continue your saved game to be able to manually save and earn achievements with the code(s) in effect.
Note: This must be done before finishing a level, otherwise your profile will be flagged as using cheat codes.
