Metal Maniax

A demolition derby-style game.  The game comes in a twin sit-down cabinet that is truly massive.  The seats move with the action and slide around when hit.  There are two speakers mounted on each seat plus the rumble sound of a subwoofer under your seat.  There are speakers in the top of the cabinet giving you four points of audio, creating a 3-D surround effect.  Interestingly enough, the name Carmageddon is written on the side art, but this prototype was developed quite a while before the hugely successful PC game of the same name.  The machines were linkable.  There was an extra stand that went in between the linked machines (four drivers total) which had massive starter lights (like a drag racing 'Christmas tree').  These units were simply comprised of lights in a tall box molded to the shape of the cabinets..
