Mortal Coil (
http://www.mobygames.com/game/dos/mo...n-intelligence) ? I saw it for the first time in the games magazine (december 1995) and then in 1996 as the demo in a computer shop. I liked it because I had too slow computer to run any other 3D FPS than Catacomb Abyss or Wolfenstein 3D that time, but reviews weren't so positive.
