Rage Against the Machine and Audioslave guitarist Tom Morello will appear as a boss character in Guitar Hero III: Legends of Rock, joining the previously announced Slash from Guns N' Roses and Velvet Revolver. Rumored earlier in the week by a German brochure (reportedly from publisher Activision), Morello's appearance was confirmed today via a Rolling Stone blog post, in which the guitarist admitted that his real-life skills don't necessarily carry over when he plays the game.
