|Guitar Hero III: Legends of Rock is a music rhythm game, the third main installment in the Guitar Hero series, and the fourth title overall. The game was published by Activision and distributed by RedOctane. It is the first game in the series to be developed by Neversoft after Activision's acquisition of RedOctane and MTV Games' purchase of Harmonix, the previous development studio for the series. The game was released worldwide for the PlayStation 2, PlayStation 3, Wii and Xbox 360 in October 2007, with Budcat Creations assisting Neversoft on developing the PlayStation 2 port and Vicarious Visions solely developing on the Wii port respectively. Aspyr Media published the Microsoft Windows and Mac OS X versions of the game, releasing them later in 2007.
Guitar Hero III: Legends of Rock retains the basic gameplay from previous games in the Guitar Hero series, where the player uses a guitar-shaped controller to simulate the playing of lead, bass, and rhythm guitar parts in rock songs by playing in time to scrolling notes on-screen.
