The Guns N' Roses frontman has just filed a $20 million lawsuit against "Guitar Hero" maker Activision claiming its use of the GNR song "Welcome to the Jungle" violated a deal not to include any imagery of ex-guitarist Saul Hudson (aka Slash) in the popular game.

In an amusing lawsuit filed in Los Angeles Superior Court on Tuesday, Rose and his Black Frog Music claim Activision Blizzard fraudulently induced Rose into authorizing "Jungle" for use in "Guitar Hero III" by telling him during negotiations that it wouldn't feature any reference to the former GNR member or his subsequent band Velvet Revolver.

" began spinning a web of lies and deception to conceal its true intentions to not only feature Slash and VR prominently in 'GH III,' but also promote the game by emphasizing and reinforcing an association between Slash and Guns N Roses and the band's song 'Welcome to the Jungle,'" the complaint states.

When Rose found out that a Slash-like character and Velvet Revolver songs would be included in "GHII," he said he immediately rescinded the authorization for "Jungle," but Activision allegedly lied and told him the inclusion was just for the purposes of a trade show.

Then "GHIII" came out and its box cover featured "an animated depiction of Slash, with his signature black top hat, long dark curly hair, dark sunglasses and nose-piercing," according to the complaint. In short, the former GNR guitarist was all over "GH III," enraging Rose.

Rose also claims that the GNR song "Sweet Child 'O Mine" was used in an online promotion for "GHIII" despite only being licensed for "GHII." He wants $20 million in damages from sales of the popular game.

"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," says Rose lawyer Skip Miller, "The relief we are seeking is disgorgement of profits and compensatory and punitive damages."

Activision has not yet responded to the complaint. -reuters.com
