Could also be called 'lost in space'.  Tricky map good for 3-4 players with room & ammo enough for eight.  Eight sided center arena with stairs & passageways all over the joint, feeling of walking in space but walkway materializes as you go.  No rechargers or teleporters.  Elevators here & there and Pfhor for solo play.  Lots of running around, complex design for Arena play.
