Intellivision Productions owns the prototype of this game. A description of the game from Mattel's 1983 CES press kit reads: 'Stuck on top of the Tower of Mystery, you must preserve your strength and protect the treasure as you attempt to escape.' An early working title was 'Dungeons and Dragons III'. This was to be one of the 16K Super Cartridges with 2K of onboard RAM, and having 8 different types of screens. A 1984 press release catalog stated this was under development for release in 1984. Unfortunately, Mattel Electronics closed in January 1984, one month before the scheduled completion of the game. The game was one of only six Atari titles officially still in development at the time of the closing. All that survives is the demo shown at the January 1984 CES in Las Vegas, and later at CGE99. Unfortunately, due to copyrights (TSR is now owned by Wizards of the Coast), the ROM for Tower of Mystery cannot be released to the public.
This game has been leaked on the Atari 50th anniversary game. For any future viewers

Jane: Your game looks incredible! Is there any chance you have a copy of the ROM or source code? If the name were changed, there'd be no trademark issues with Wizard of the Coast, just like was done with the Intellivsion version. Perhaps we could convince Tommy Tallarico (new owner of Intellivision) to release this and the Atari version of Treasure of Tarmin. Maybe you'd be interested in finished this the way you had originally wanted to?

I was the original programmer & also did all the graphics, before being laid off and then Mike finished it. I also have chips from before Mike worked on it. The dungeon layouts were my friend's intials. See http://www.intellivisionlives.com/bluesky/games/credits/atari3.shtml
