Ninja Difficulty An elite difficulty level called Ninja is available for selection in the game once you have won every trophy and successfully completed each head-to-head race. Sounds easy huh? right!
All Cheats Although all of the cheats are listed here already, they can be unlocked for selection automatically when certain conditions are met in-game. First, you must achieve a first place finish in all of the global events, which will bring you to one last head-to-head race. After winning that race, all of the cheats will be unlocked in the same place where the cheats are otherwise inserted in the game.
