The Guitar Hero series is known for its generous cheat codes that help
you reach your true rock star potential, so it's no surprise the
PlayStation 3 version of Guitar Hero III: Legends of Rock has
cheats that improve your score and accuracy. There's even a code to
unlock every instrument, song, and secret character in the game.
Note: These cheats are for the PS3 version.
How to Enter Cheats in Guitar Hero 3 for PS3
Instead of using the PS3 controller to enter cheat codes, input codes
with the guitar-shaped controller that comes with the game. Select Options from the main menu, then select Cheats > Enter New Cheat. Once a cheat is unlocked, you can toggle it on and off from the Cheats menu by pressing the Green button.
Guitar Hero 3 Cheat Codes
The codes below refer to colored buttons on the guitar:
- B = Blue
- Y = Yellow
- G = Green
- R = Red
- O = Orange
You should hear the actual chord as you play it; however, no sound is emitted when you hold down four buttons at once. When you enter a code correctly, you'll receive a confirmation message that a cheat has been unlocked.
Note: Activating some cheats will disable achievements.
