What shall I say Damn, thats just to cool. Amazing modeling by your team, decent framerate, well done level design. Can't wait to play a demo if there'll be one. Tell me, how did you do it? I don't think you made the level out of CSG, because that would probably have killed the framerate, so it must be models. Did you use baked textures for lightmapping? I love the screenshots, I think I'm gonna rate you 5 stars for that.
