A sprawling grungy industrial environment suits the intertwining game flow and layers. The two floors are well spread out with good clean areas that are well sized for fighting.
Connections and game flow are great for a 4 player DM. The architecture is sweet and the octangular corridors give the level a touch of sci-fi aesthetic, nice. Bots play ok but seem to hang out by the Quad.
Very nice map, grab it!
