Guns N’ Roses frontman Axl Rose filed a $20 million lawsuit Tuesday against Guitar Hero III: Legends of Rock publisher Activision, according to Variety. The singer alleges that the videogame publisher broke a contractual promise by featuring former Guns N’ Roses guitarist Slash in the 2007 game. According to the suit, which was filed in Los Angeles Superior Court, Activision obtained the song rights for “Welcome to the Jungle” from Rose under the condition that Slash would not be featured in the game. However, the suit says Guitar Hero III “prominently features Slash imagery in direct connection with the use of ‘Welcome to the Jungle,’ exploits the prior association between Slash and Guns N’ Roses, promotes Slash’s and [his band] Velvet Revolver’s separate interests, and includes Velvet Revolver tracks as available downloads, all of which was directly contrary to the contractual obligations” of Activision.
