Guitar Hero III: Legends of Rock Codes (Wii)

The GH III Wii version of the game has several exclusive features, since a Wii Remote must be inserted into the guitar controller. The game utilizes the Wii Remote's wireless capabilities and accelerometer, but will also make use of the rumble feature and the internal speaker. The internal speaker on the Wii remote can also be optionally set to emit an effect when wrong notes are hit. While the Wii version has online play utilizing game-specific friend codes, downloadable content will not be available initially.

Guitar Hero III introduces Battle Mode, a competitive mode between two players either locally or over network play. The mode puts a twist on the Pro Face-off mode introduced in Guitar Hero II. Two players will face each other, trying to complete a song while successfully playing Star Power sequences to earn attacks that can be used against their opponents. Players will be able to store three attacks at a time and can activate them by tilting their guitars upward, but the attacks are only temporary. If neither player fails the song, they will face each other in a Sudden Death segment. (Wikipedia)
