Looks like the update just now added an new valve-made map called CP_5Gorge; it'll be interesting to see what it looks like. Any chance we'll change one of the servers to it (at least for a while?).
Different sections of the map are good for different classes I noticed. The middle parts are heaven for spies and scouts. I had quite a good time sniping too. It's not too often that indoor areas are good for sniping. I liked it and look forward to playing on it some more!
