How to enter Cheats codes
Button cheats are available on all platforms. You must enter the cheat codes on the gamepad, much like classic GTA games. Use the D-pad to enter the directional commands (LEFT, RIGHT etc.). These codes must be executed fairly quickly. A small confirmation will appear above the map. Entering cheat codes disables Achievements and Trophies, but only for the current play session. Reset your game and your Achievement/Trophy ability will return.
