Guitar Hero: Warriors of Rock is a 2010 rhythm game developed by Neversoft and published by Activision. It is the sixth main installment and the eleventh overall installment in the Guitar Hero series. The game was released in September 2010 for PlayStation 3, Wii, and Xbox 360. Similar to previous entries in the series it is geared towards playing in a four-person band experience, including lead and bass guitar, drums, and vocals. The game is available as a standalone title, allowing players to use existing compatible instrument controllers, and as a bundle that provides these controllers.

Guitar Hero is a series of rhythm games first released in 2005, in which players use a guitar-shaped game controller to simulate playing primarily lead, bass, and rhythm guitar across numerous songs. Players match notes that scroll on-screen to colored fret buttons on the controller, strumming the controller in time to the music in order to score points, and keep the virtual audience excited. The games attempt to mimic many features of playing a real guitar, including the use of fast-fingering hammer-ons and pull-offs and the use of the whammy bar to alter the pitch of notes. Most games support single player modes, typically a Career mode to play through all the songs in the game, as well as competitive and cooperative multiplayer modes. With the introduction of Guitar Hero World Tour in 2008, the game includes support for a four-player band including vocals and drums. The series initially used mostly cover versions of songs created by WaveGroup Sound, but most recent titles feature soundtracks that are fully master recordings, and in some cases, special re-recordings, of the songs. Later titles in the series feature support for downloadable content in the form of new songs.
