Activision has revealed the lineup of launch week downloadable content for the upcoming Guitar Hero: World Tour. Available exclusively on Xbox LIVE Marketplace for the Xbox 360 for two weeks starting October 30th, the R.E.M. Track Pack features three songs, which can also be downloaded as singles, from the band's newest album, Accelerate, "Horse to Water," "Man-Sized Wreath" and "Supernatural Superserious."

Available at the launch of Guitar Hero: World Tour is the Classic Rock Track Pack that offers fans three rocking party anthems "Rock and Roll Band" by Boston, "Hot Blooded" by Foreigner and "Jessie's Girl" by Rick Springfield, also available for download individually. Created specifically for Guitar Hero World Tour, the Guitar Duels, original compositions by Ted Nugent and Zakk Wylde, will be available for free at launch to download and play outside of the Career.

Fans who have been shredding to Metallica's critically acclaimed Death Magnetic on Guitar Hero III: Legends of Rock since its release with the album need not purchase the album again as it is forward compatible and will integrate seamlessly with Guitar Hero World Tour. The Death Magnetic downloadable album, compatible with both Guitar Hero III: Legends of Rock and Guitar Hero World Tour, will continue to be available for download on Xbox LIVE Marketplace for Xbox 360 and in the PlayStation Store for the PlayStation 3.
