Tried it out for the first 2 levels. It's pretty good for its time. I was drawn into DOOM at the time, so I never had the chance to play it. I find the detail, although more grusome, more textured in DOOM.
But the addition of talking characters and animation was interesting. Not sure that would work for the original DOOM.
Kyle looks a bit like Hon, LOL. Only know the bearded guy from Jedi Knight.
