Nice, thanks for sharing the suff!
I think I haven't seen some of the
Shadow Wariror screenshots before, although most pre-view shots are collected at the RTCM website (which seems to have gotten down recently, as I've just found out). Some of the shots were featured on the Apogee website, I remember finding archived pages via the Wayback Machine and posting them
here.
[Edit] I've just posted links to the original zipped slideshow previews of Apogee/3D Realms games
here.
