Rose claims that Activision broke their agreement by including both Slash and the band's hit song "Welcome to the Jungle". He states that in purchasing the rights to the song, Activision agreed not to make reference to Slash or his new band, Velvet Revolver; however, Rose later found a character on the cover of the game that resembles Slash with his signature black top hat, long curly hair, sunglasses and nose piercing.
In addition to including Slash, Activision also used the Guns N' Roses song, "Sweet Child O' Mine" in an online advertisement for Guitar Hero III, while only purchasing a license for Guitar Hero II.
"This lawsuit is about protecting Guns N' Roses and 'Welcome to the Jungle,' and is about holding Activision accountable for its misuse of these incredibly valuable assets," Rose's lawyer Skip Miller said. "The relief we are seeking is disgorgement of profits and compensatory and punitive damages."
Rose is seeking $20 million from Activision for their alleged negligence.
