Circles inside of circles inside of circles inside of... Lots of staircases. A central (small) courtyard. Be sure to collect your weapons and ammo before going in...
A central covered arena, with a surrounding lava moat and a second arena above. Judicious use of 5D space to supply a nice quantity of carnage space. Also available in an Infinity flavor.
A huge, wide-open, nicely-built killing area. Weapons and ammo come in clumps... so if you want a particular weapon, you also get lots of ammo for it. Also comes in Evil and Tempus Irae flavors.

A simple, square arena enclosed by a wall. Access to the wall is gained by climbing the water towers... but the towers can be enclosed in solid columns. Careful if you're going up, and someone's near the switch! Also available in an Evil flavor.
