Well looks like Rage Against the Machine is in Guitar Hero, according to Gametab.com. Definitely going to be a fun song to play if you ask me. This announcement will actually make me want to buy and play GH III just a little bit more, now I like about 15 songs.
"The game's new boss battles (that also includes Slash of Guns N' Roses fame) having gamers going head-to-head in an attempt to deplete the boss' "Rock Meter" before the boss starts shredding on their "Death Drain" solo. Once defeated, players continue on to their encore, which will be a master recording of a well-known track from said boss' respective band. In the case of Morello, players will jam on Rage Against the Machine's "Bulls on Parade.""
