Clone
Photos of this prototype game were discovered inside the Orbitor 1 prototype game. This game was a similar design to Orbitor 1 with an irregular plastic surface for the playfield and extruded 3D backbox artwork.
It is currently unknown whether or not this game still exists, or if there was more than one constructed.
