Wow! An abandoned Devlin Breeding Station, cool! A series of walkways over nests, & watch out, they tend to drop out from under you! This is great for solo play & author says leave aliens on for net.
Based on the author's house... really light on weapons and ammo, and with some nasty smearing once the place is flooded (weird liquid heights in neighboring polys).
Two levels, the first sort of a concept level. Very interesting architecture, but the switched doors get old after a while. If you're building sweeping spaces, download this map... you might get some very good ideas.
Two large levels, with lots of tunnels. (did I say tunnels?) If you are the type of net player that likes to fire it out head on, then these levels are for you.
