Another variation on the Flame Pits theme. Also comes in an Infinity flavor.

The most complicated (and in some ways, the prettiest) of the Flame Pits levels. Very nice flow, once you get the hang of it... before that, it's easy to toast yourself running out a doorway on the outer ring. Also available in an Infinity flavor.

A large open area with 4 lava-filled pits. Switches on the outside edge control the lava height... and the aliens that can nail you. Best as KOTH, but playable as EMfH.

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 Evil flavor.
