Guitar Hero 6 will not feature playable celebrity likenesses.

Maybe legal arguments with No Doubt and Courtney Love have swayed Activision.

The game will instead allow real-life legends like Metallica founder (and drummer) Lars Ulrich to be recruited in Quest mode, according to Official Xbox Magazine. Complete their songs and you'll unlock a uniquely-powered alter-ego. Character Warrior Lars has a maximum 6x multiplayer.

Kiss hero Gene Simmons will narrate the Quest mode.

Guitar Hero 6 aims to return to the series' foundations, reinstating the old characters and focusing more on Rock n' Roll.

Streakers, Momentum and Do or Die will be available in online modes, and all DLC will be carried over into the new game.

Glam rockers Queen, Kiss and Black Sabbath have been confirmed

Guitar Hero 6 hasn't been officially unveiled but has been talked about by Activision in financial reports gone by. Expect full word soon, especially with E3 around the corner. -eurogamer.com
