A large, concentrically built map, with rings of passageways around a central force-fielded square. Comes in two flavors, with the second map being an expanded version of the first. Nice construction, and good flow all around...
Arena play doesn't get more straightforward than this map. Ledges for sniper shots, what appears to be a crusher in the middle but no luck in activating. No rechargers, no frills.
Large inner circle with surrounding stairs leading off to four corner rooms/areas where weapons & ammo can be picked up. Stairs for ammo also. Central area of circle continually raised Compilers upon entering, only alien to be seen. 2x canister. Probably would work as KOTH or tag.
This map is very claustrophobic. Lava pit but you can walk on it. Elevators to no particular place. Corridors with no straight shots to be had. You might like it if you like suddenly rounding corners to . . . . Blam!
