It's not particularly pretty, sorry!
Quick map to try out some gameplay I wanted to see more of.. has a fairly compact but open, circular layout with interesting up/down fights. Instead of the usual RA/YA it has YA with 2x (MH+GA) for some more, err, dynamic gameplay. Lava to be shot into. Splashable ceilings. Low ammo count (2x small LG, 2x small rocket packs), but easy SSG/SNG from some spawns to hopefully get some surprise kills. 1 tele, 1 lift, 1 air tunnel.

This being "b12" not sure how many more versions there will be, I still have some ideas for improvements, but this is likely largely it.
