Guitar Hero III: Legends of Rock/Walkthrough

Multiplayer
Face-off: Two players take turns during the song to achieve the best crowd level in the game. They can choose their own difficulty to satisfy their needs. Pro Face-off: This is similar but they must be on the same level and can be tougher to achieve the crowd level to succeed. Battle: This is like Face-off but this is a Mario Kart version of attacking each other. Also if they tied, sudden death ensues and only one person wins. The star power is replaced as weapon attack and can be saved up to three items.
