Guitar Hero 3 Hyperspeed is a specific cheat code that makes the Guitar Hero 3 gameplay faster. This can be used on any difficulty setting, from Easy to Expert.

So you say you've beaten every song that Guitar Hero 3 has to offer on Expert mode? Bored? Need a new challenge? Try Hyperspeed. With five different speed settings, hyperspeed offers the ultimate challenge to any rockers skilled enough to take it on. Though Xbox 360 offers no acheivements for this and none of the other versions record your feat, beating the game in expert mode at the highest hyperspeed (level 5) gets you one thing that no one else can offer you: sweet, sweet bragging rights.
