Guitar Hero is a music video game developed by Harmonix Music Systems and published by RedOctane for the PlayStation 2 video game console. It is the first entry in the Guitar Hero series. Guitar Hero was released on November 8, 2005 in North America, April 7, 2006 in Europe and June 15, 2006 in Australia. The game features a guitar-shaped peripheral (resembling a miniature Gibson SG) as the primary controller to simulate the playing of rock music.
Guitar Hero has won many awards from major video game publications, and its success spawned the 2006 sequel Guitar Hero II for both the PlayStation 2 and the Xbox 360 and Guitar Hero Encore: Rocks the 80s for PlayStation 2. A third full installment, Guitar Hero III: Legends of Rock, will be released for Xbox 360, PlayStation 3, Wii, PlayStation 2, PC, and Mac in late 2007.
