The windows and Linux ports of this now feature Hi-res textures as well as 3D models. It would be nice to see such features for MorphOS and OS4 machines as they obviously should have the power to pull that off.
As for the basic incarnation, I can't believe it is running as crappy as people are reporting. That is just sad!!! This is one of the best and most innovative FPS games ever, right next to DOOM, System Shock, and Shadow Warrior. I'd LOVE to see a quality port to the Amiga, and from the sounds of it, I shall avoid the current edition available on Aminet.
