The following codes have no effect until you complete both levels with a five star rank on the hardcore difficulty setting to unlock them. Each code has two parts, each of which are unlocked by a specific two levels (for example, completing levels 17 and 18 with a five star rank unlocks the "Invisibility" cheat). When this is done, one half of a code will appear at the bottom of the image that is now unlocked in the "Bonus Features" menu. Once both halves (images) are unlocked, enter one of the following codes at the main menu to activate the corresponding cheat function:
