I've checked out all of the wads Eric (Reb) made that I've been able to find (available for download here). I used Doom 95 with a Doom2.wad, on Windows 98. I played UAC Labs many times and never beat it: I didn't used cheats and without them, it's virtually impossible to defeat the hordes of enemies Eric throws at you. While touring them, I took some screenshots of the deathmatch levels that Eric created. You can find links to each wad's screenshot pages below.
