Apparently, someone going through the art assets in S.T.A.L.K.E.R. discovered files from Doom3 and HL2. Some were modifed, but still retained the orignal filename(s).

I find it browsing through the comments section pretty fascinating. Seems like some people think the whole thing should be forgiven since S.T.A.L.K.E.R. was made by a small company. I'm curious as to how much money someone needs to make before opinons changes from "Awww, let the poor underdog small devteam use stuff from the big company's games!" to "Sue the crap out of the no-good, thieving, rich megacorp for theft!" :)
