Quoted from Biffbar:Hyperball is interesting, but really loud. There were noise complaints about Hyperball & Rapid Fire when the pair showed up at one of the old Allentown fire hall pinball conventions.
I have a hyperball, very noisy but fun and underrated game, takes some balls to bring it to a show to get used all day, not sure the original boards and shootercoil would hold up for a show, maybe add some more fans to keep it cooler
