Choose from the following list of manufacturers to see their plans and prototypes for unreleased laserdisc games.



Atomic Castle - Laserdisc Computer Systems (LDCS) originally intended for Atomic Castle to be released in 1983.  But after many delays, the game never made it into full production. The game was tested in local Massachusetts arcades but no known copies survive. The object of the game was to make your way through the castle, while fighting radiation orbs and undead monsters. Your ultimate goal was to disarm a doomsday device which was located inside the castle.  Below is a picture of the promotional flyer and a couple screenshots from the laserdisc (screenshots courtesy of

Eon and the Time Tunnel - This was the prototype / demonstration version of Atomic Castle.  This name appears in many arcade gaming articles from 1983 - 1984.  

Pitchman - A target shooting type game featuring Dr. Slye who roams thru rooms in a carnival-type scenario.

Michael Harris (technical director at LDCS), by way of Keith Smith:
The game was originally called Dr. Slye's Sideshow and later renamed Pitchman. We began leaning towards designing games with wider demographic appeal, and several of us were converted to (and still espouse) the "competitive not combative/action doesn’t mean violence" religion. Pitchman was our most elaborate (and IMHO successful) design in that direction. The live-action material starred Steve Sweeney, now a fixture in the national comedy club and B-movie world, in a well-done "carny from hell" role. Each phase of play was built around a different sideshow booth: a dart-throwing balloon board with prizes under some balloons, a pitch-the-baseball booth (hence the name) with constantly increasing numbers of bizarre moving targets, a roller coaster that tended to jump the track into different dimensions. Game play was very tricky. As was usual with our games it involved extremely tight interactive blending of high-res video on laser disc with low-res real-time computer graphics.

Unfortunately, the game was never completed. A single prototype was built with about 4 of the planned 15 or 16 booths working (and only a couple of those were completely finished) but by that time Stern had exited the video game business entirely and the project was cancelled.

Gold Medal w/ Bruce Jenner - Only two of these machines exist today.  These two cabinets were shown at a 1984 AMOA trade show, but Stern decided against the production of these games.  Below are pictures of the cabinets and some screenshots & video clips taken from the laserdisc.
