Good tip.
As far as I know this is the first mouselook game. Also one of the first to have had actual 3D enemies, including humanoids. Also the amazing intro theme, and in general the atmosphere was pretty good.
I remember the oppressive mood, especially in some of the indoor areas. Those damn missile turrets hit hard like it was going out of style.
Looking at some gameplay now, it’s more freeform/open world than I remember. The Daggerfall xngine roots are clearly visible.
