Tube Chase

This later became Tunnel Hunt.  After the vector hardware was cost-reduced a few times, it was changed to raster graphics, renamed Vertigo, and sent to Exidy (likely some time in 1980 or early 1981).  Exidy tested it for a short time and then decided not to buy/license it and sent it back to Atari.  Atari renamed it Tunnel Hunt and licensed it to Centuri in 1981, who released it in 1982.  So Tunnel Hunt was the exact same version Exidy originally had.  Atari (with Owen's help) designed the Tunnel Hunt cabinet.
