3 Maps. These work better (imo) as M2 maps, although they play faster, for some reason, as M1... The M2 version is called M2 Suicide 13.

An interesting remake of a great M1 level. This map won't play well on slower machines, but the original didn't either... great care has been taken to keep flow similar to the original, while making an interesting M2 map. Check it out!

2 maps. Modifications to House of Pain. One water map, one lava map.

A very cool concept. 6 existing net maps (7, if you count the one that's duplicated) are strung together with terminals. They're all small arenas (Pfhorever, Citadel of Antiquity, others of that type), and when one player accesses the terminal, all players jump to the next level, with all their weapons. This should keep you from getting bored with the scenery.

An interesting looking level... lots of elevations. Watch the landscape areas... they'll kill you in more than one way. (It's kind of satisfying to take out a Juggernaut that can't hurt you, though...) Update fixes a crashing bug.

Huge open spaces, surrounded by smaller rooms and even smaller passageways.

A convoluted map, with teleporters everywhere, lots o' baddies (or just some, depending on which version of the map you play), and the Gallerie de Despayre, where nasties fall on you unremittingly from out of the sky. Rain of Pfhorror, with the excess baddies, is great for solo practice, and Drizzle of Pfhorror holds an acceptable number for net play. Been sitting in my inbox for way too long now...

Three maps. These weren't submitted-I snagged them off their web page. They're simple-they were designed to play well on a passive-matrix powerbook-but they're fun. And they're quite small. The readme is simply the text of the web page.

Three levels, all quite a lot of fun. (Swiss Cheese, especially...)
