Also turns out they tried to rectify the whole "can't sell game in Germany cuz shooting humans is bad there" thing by doing a "Probotector" as I call it (basically for the Europe versions of the early Contra games, Konami turned all human characters to robots and renamed the game), seems like it would was a bit too much trouble and they dropped that idea.
The skin itself seems to have floated around sites for a while but seeing as no readme was there, the author got lost.
This is actually one of the skins I made for the German version of UT which is a modification of the Raw Steel guys. I had to make them into robots because you can't have people killing people in Germany for some reason, I bet they loved DOOM . I thought why not post it for the US guys to use. If you want to use it just place the SoldierSkins_OverKill.int in the system directory and place the SoldierSkins_OverKill.utx in the textures directory, and thats it.
