A large, open level with ledges leading to a central hill, all surrounded by lava moats. If you fall in, find an edge near the hill... you're not toast yet. Also available in an Evil flavor.

A cool idea, in concept... but we couldn't get it to work for us. The idea is that you've got a bunch of interlinked rooms... and monsters in a different part of the level will open and close connecting doors, seemingly at random. If it works, it's pretty cool... you'll never know if that grenade you shoot is gonna blow up in your face as the door closes. In practice, we only had a couple of doors open and close for us...

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.

A central building with some very confusing insides, and a few outer passageways. Hard to get used to.
