Guitar Hero II is a music video game developed by Harmonix and distributed by RedOctane, and is a sequel to Guitar Hero. The game was released first to PlayStation 2 in 2006 but later released for the Xbox 360 in 2007. Guitar Hero II challenges players to recreate the lead guitar portions of many rock music songs using a specially designed guitar-shaped controller, based on either a Gibson SG for the PlayStation 2 version, a Gibson Explorer for the Xbox 360 version, or else a standard console controller.

Successfully hitting notes improves the player's performance in the game and also raises their score, whi
