Tight, almost claustrophobic corridors, lots of teleporters, and bobs everywhere. Easy to kill a few by accident (and then your friends aren't the only ones out to get you...).

A multilevel arena. With aliens on, you're gonna be spending most of your time fighting ticks.

A large level, with architecture reminiscent of the author's Alhambra. A bit darker, though... and with more indoor space. The author has suggested a somewhat unique solo method of play-see the readme for an URL with details.

A dark arena with some sniping areas around it. A straight port of the M2 version.

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.

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.

Modeled after the Math/Science building at UConn. Multi-level, open map, rather dark overall, but with plenty of bright areas. Flow is good, elevators are nice and fast, ammo is plentiful. Also available in an Evil flavor.

A lava-filled level with a physics model that enables flying. Controls take some getting used to-when the run key is pressed, there's gravity, when you let go, gravity is gone. You can use your fists to move around (left is backwards, right is forwards), and grab the goodies in various alcoves around the place. Expect to die a few times in the lava before figuring out the flying... we found it was the most common form of death in the beginning.
