Demon Destroyer Gunn

The Demon Destroyer Gunn is a PC controller created by TAC Systems, Inc., and originally released in  for a manufacturer's suggested retail price of $99.00. The controller's weapon-shaped profile is modeled after the chaingun from Doom, and evidence strongly suggests that TAC Systems originally intended to license the Doom brand from id Software for the product. That the license went unused may be due to the product's poor reception - it earned the number two place in the  list, "The 15 Worst Peripherals", in the magazine's November 1995 issue, citing unreliability, unusability, and poor appearance. Note that, despite the controller's gun-like design, it does not possess any motion sensing or light gun capabilities, and simply acts as a mundane analog two-axis, two-button PC game controller.

The controller included a CD-ROM with several shareware games, which included Doom and Heretic.

As the "DoomGunn"
Evidence abounds that the product was to originally be called the "DoomGunn". An H2HMud announcement on the Usenet group in August 1995 explains that TAC Systems had signed on as the first official sponsor of the then-upcoming H2HMud North American Deathmatch Tourney, and would provide a DoomGunn to each of the top twelve players in the tournament. In addition, contemporary articles in Computer Gaming World and Micromanía refer to the product directly by that name, or explain that its name had changed but that it was still the same product.

A Designer News forum post by Stuart McCoy, the designer of the controller's packaging, explained that the DoomGunn name was in use at the time of his work, and that his original design used lettering resembling the Doom logo, rather than the "faux metal texture" found on the final box.

Finally, early specimens of the controller actually retain the name, along with a dubious trademark stamp (no registration with the United States Patent and Trademark Office appears to have ever been successfully made for the mark), on a panel on the right side of the controller, which on later models is entirely missing the top line of text which only reads "DoomGunn".
