Released in November 1992 in Japan.
This game was released as a conversion kit for Time Traveler since the laser disc players in the original games turned out to be unreliable.
This is the only game other than Time Traveller to use the hi-tech hologram theater cabinet created by Sega. Indeed, Holosseum was written to convince arcade owners that it was worth investing in the expensive cabinet. The Winners Don't use Drugs message distorts in the real cabinet, as it was programmed incorrectly, beyond the range of the projection mirror. The theater works because of a concave mirror inside the cabinet, which reflects a specially framed image produced on a standard monitor. Because of the nature of a concave mirror, the focussed image appears as if it is floating in mid-air, provided that the interior of the cabinet is painted black to absorb any excess reflection (Note the pure black background on both of these games). Also, the image focus may appear to change across the screen, this is due to having to take into account the thickness of the mirror at different points, known as spherical aberration).
