Heavily inspired by What Goes Up (M1). There is some texture alignment needed, and the bobs can be seriously annoying in net play, but this is a pretty well thought-out map. Most areas are vulnerable from multiple directions, and there are very few (if any) resting places. Keep an eye out for secrets... some of them can make inter-area travel much easier. Update aligns most of the misaligned textures.

An extremely playable variegated arena. Lots of platforms, but jumping distances have been planned quite well, and the alert player can use pillars and tunnels as missile blocks quite effectively. The teleporters on the bottom bring you up to sniping positions on the outside pillars... anyone trying to stay on the low hill should keep a sharp eye out above.

If you think you've found all the secrets in this level, you haven't played it long enough. Lots of doors that don't look like doors, but there are some very nice navigation tools, fun lighting... and more than enough ammo to keep your whole group dying.

A 2-level solo map. Wow-this one's pretty impressive. The terms leave a little to be desired, but the author is Japanese, so be gentle. (They're at least understandable.) The level design, however... very, very nice. The last room will keep you busy for quite a while, unless you're a very adroit sidestepper. Classy use of solid transparent walls... If at any point, you feel lost, go back and check a previously sealed door, or broken switch. Also available from its own web page.
