RedOctane's follow-up to the critically acclaimed rhythm game. Guitar Hero II features a brand-new and expanded track list, more venues and new play modes, and aims to rock longer and harder than its predecessor. RedOctane has once again teamed up with veteran music game developer Harmonix for the sequel, and is using famed recording studio WaveGroup for its music production, who also recorded the covers for the licensed tracks in the original Guitar Hero. The Xbox 360 version also adds 10 new songs, downloadable content features, leaderboards and online features, plus support for the Guitar Hero X-Plorer guitar controller.
