@ Kingshot: You could also use phong shading for smoothing the round walls. At the moment it somehow reminds me of the old Half-Life. (best SP game imo) When using patches it will become difficult to shape, normal brushes are way easier to use. But when you decide to use normal brushes you should flatten it more.
