I was over at the new UT3 portion of the official U.S. Playstation forums and a forum member named Scott84 posted a link to a new map. I tried it out and thought you may wish to as well. It works and is a fun little map for a death match. I played it versus some bots and enjoyed it.
I did not make it or discover it and do not claim any responsibility or liability for it.
