Based on a Quake level (title and author unknown). Simple Gothic style large split level hall with ring corridors, launch pads across the third level and a red fog layer just beneath the ceiling. The corner bounce pads lift you to a narrow ledge running around the hall just below ceiling height hidden by the fog. Gameplay is best with 3 but it gets a bit crowded with more. Bots are fine until they find a corner bounce pad :[

OK for a short while.
