A elevated center tower connected to a outer ring. The paths to the ring are cool but the pits are filled with sewage. The flow at times seemed to be obsturcted with the ease of finding the teleporters in the pits. (Why it is a good king of the hill map--if you play it on EMFH, then the flow comment will make more sense) Will support king of hill great...The switches will also aide in this endeavor, although the film will not show it. Good construction and the use of one ambient sound just about blew me out of my room.....(if you use a subwoofer) Solo is possible---the readme explains the aliens that can be used.
