The Arockalypse features many guest-stars on its tracks: Dee Snider and Jay Jay French from Twisted Sister, Udo Dirkschneider from Accept and Bruce Kulick from KISS. Before the album was released in Finland, there were rumours about other possible guest-stars to feature on the album, including Sebastian Bach from Skid Row, Alice Cooper, King Diamond, Rob Zombie, and other members of Kiss, the latter being Lordi's greatest influence. In reality, only Sebastian Bach and Alice Cooper were ever asked to be guests on the album, but neither were able to make it.
