Are you a Hardrock Newbie, Hardrock Rookie, Hardrock Pro, Hardrock Boss or a Hardrock Meister? Fortress developed a special Facebook app for the Hard Rock Cafe.
By answering 11 questions, users can find out what kind of Rock type they are. The questions are all linked to the Hard Rock Calling Festival. The app was placed on several local Hard Rock Cafe Facebook fan pages, like London, Amsterdam and Berlin.
