Q.U.A.L.K.E.R is a S.T.A.L.K.E.R conversion for Quake 1.
Surprisingly functional and fun. Really odd and intriguing to explore. Fascinating... I never suspected such things could be.
I'm gonna go with a 7/10
This is super neat and bizarre and that immediately makes it way higher of a rating.
In terms of actually playing it as a game? It's completely broken (first alpha release of something SUPER outlandish so that's expected)..
I absolutely look forward to seeing what you make of this, and I'll edit this if things become more refined.
