I have downloaded and played the map. There is some very interesting SOCcing that I myself would probably never have thought of. However, the music does not seem very fitting.
I suppose I do not have much room to criticize, considering that I have never really played CTF other than with bots. However, I think that the map’s main flaw is the placement of the ring weapons. I am not saying that the rings should be difficult to get, but in that map, it is a bit too easy to get several types of rings in a small span of time. Due to the wide-open spacing, I would recommend leaving out the rail ring.
Though, I suppose you should take my advice with a grain of salt. Once again, my experience with CTF is not as extensive as many of the others on this board.
