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.

Arena play, no, it's linear. Perhaps tag. Not KOTH. This is a very complex map, supports solo play (whacko Bob's again) and is full of passageways, elevators, 1x, all connected by spacious outer perimeter encircling entire area with interior sewage passageways. Doors for this, doors for that. Very fast in the running department. Read Me is in a terminal within the game. Clever

Arena play; 2x available, cramped for 6 players but could be done, few fighters to distract and a Crusher for fun. Ammo is somewhat scarce, on purpose. One secret.
