Activision's music game Guitar Hero World Tour is now available to purchase in stores and online. The Rock Band-like multiplayer Guitar Hero game adds a singer and drummer to the guitar play mix. Cameos from legendary musicians are included in the game and download tracks will be made available for purchase for all platforms including the Wii.

The initial track list has 86 tunes from bands like The Eagles, Van Halen, Ozzy Osbourne, and more. Guitar Hero fans wanting a more cooperative play environment that allows more friends to get into the action have waited for this game. It will be interesting to see if Rock Band 2 or Guitar Hero World Tour sells more this holiday season.

"Only Guitar Hero World Tour has the star power and brand recognition to bring family and friends together to rock this fall," said Dusty Welch, Head of Publishing for RedOctane. "With a massive on-disc set list and a host of downloadable content on the way, new high-quality controllers, including the drum kit controller and a redesigned guitar controller; multiple online and offline gameplay modes, plus the groundbreaking Music Studio music creator and GHTunes(SM), a revolutionary user-generated music hub, Guitar Hero has again set the standard in the music-based videogame genre."
