Metroid Prime Hunters/Stasis Bunker

This place is a fair sized arena and has good ammo and health pick-ups in different locations. The imperialist is located at the vent tower(where the UA expansion was located in single-player). The main strategy here is to hide behind the blue walls and snipe your enemies or go full out on close combat. Trace has a pretty big advantage in this arena because he can hide in many tricky locations due to corners and upper levels.
