Rock legend Sting and progressive metal pioneers Tool are making their video game debuts, contributing more than just music, in Activision's Guitar Hero World Tour.

In what will be the largest collection of artists ever to appear in a Guitar Hero game, singer-songwriter, actor, author, activist and lead singer/bassist of The Police, Sting will add his voice and likeness as an in-game character. Aspiring frontmen can take the stage as Sting throughout their vocal career or play alongside him as he performs one of The Police classics, Demolition Man.

Hugely popular alternative metal band Tool, known for their epic, intense musical arrangements and killer visual arts, will also be making an appearance in the upcoming Guitar Hero World Tour. Fans will be able to rock out to Parabola and Grammy-award winning Schism from Tool's critically-acclaimed 2001 album Lateralus in addition to Vicarious from their 2006 Grammy-award winning album 10,000 Days.

The game will also feature an all-new venue designed in collaboration with the band and highlighting the art style that has become a staple in their music videos, live shows and album artwork.

Guitar Hero World Tour is being developed for the Xbox 360, PS3, Wii, and PS2, and is set for a winter release.
