Another of Nick's so many aliens I can't even play solo Maps! A Pfhor Water Reclamation Plant, not too large an area but supports up to 8 players (may be a bit crowded) with KOTH, Ball and of course, Carnage.
A very large arena level. The inner hall or area is the main arena and the outer areas are the killing zones. Some very unique design and you will need a large group or it will be slow. Supports EmfH and would be playable with smaller groups on KoTh.
