In documents filed in LA Superior Court this week, the Guns N' Roses rocker claimed that the company had violated a contract between the two which stipulated that no imagery of Slash was to be used in Guitar Hero III.
He claimed that the video game giant tricked him into authorising the usage of the band's hit 'Welcome To The Jungle' by agreeing to leave out any reference to Slash, said The Hollywood Reporter.
"[Activision] began spinning a web of lies and deception to conceal its true intentions to not only feature Slash and [new band Velvet Revolver] prominently in GH III but also promote the game by emphasising and reinforcing an association between Slash and Guns N' Roses and the band's song 'Welcome to the Jungle," the suit stated.
Rose also claimed that the company misused 'Sweet Child O' Mine' by featuring it in promotions for a game other than the one it was released for.
He is asking for $20 million in damages.
