Gray Matter Interactive Studios, who have developed Castle Wolfenstein are not the same as the Amiga Gray Matter company.
GMIS ( http://www.gmistudios.com
) are based in California and were created from old employees of xatrix entertainment.
Gray Matter was a Toronto based developer, headed by Chris Gray. The graphics guy seems to have been Nick Gray, so there was probably a family connection there, as well as the origin of the Gray Matter company name. They also did Fiendish Freddy's Big Top O'Fun, The Ultimate Ride/Superbike Simulator, Cyber Empires, Motor Massacre, Road Raider.
The question is, who did the Amiga version of Techncop - Gray Matter or Imagexcel? And who were Imagexcel? They also seem to have done a game called Quantantine on the PC.
