Plutos is an unreleased prototype game for the Atari 7800. The lack of official release means information on its gameplay, specific features, and developer is scarce.  The ‘Unknown’ and ‘Proto’ tags strongly suggest that this is an unfinished game discovered within the Atari 7800 game development archives, possibly representing early concepts that never made it to a full production stage.
