Quote from BJAWow, that looks insanely good for Q1! really like the architecture and texture work. It's a multiplayer map, right?
Nope, it's a singleplayer map. I could convert it for MP rather easily though.

What you see is possible thanks to the awesome new compilers and the ambient occlusion that was introduced a couple of months ago.
