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's development was a result of collaboration between RedOctane and Harmonix to bring a GuitarFreaks-like game to America. The game features a guitar-shaped controller (resembling a miniature Gibson SG) that the player uses to simulate playing rock music. The gameplay is similar to GuitarFreaks, in that the player presses buttons on the guitar controller in time with musical notes that scroll on the game screen. The game features covers of 30 popular rock songs spanning five decades of rock, from the 1960s up through 2005, in addition to bonus tracks.
