Basically, two rooms, separated (and enclosed) by a wall wide enough to snipe from. There are also three lookout areas that don't seem to serve any purpose at all...

Three maps. A major Juggie in every one (well, at least one...). Despite that (does my bias against monsters in net levels show?), these are relatively playable... except for the first one. (DON'T leave the main arena...) The third one's actually quite intricate... Update adds a fourth level (pretty simple, but quite fun).

A sequel to Foreign Legion 2.0. One level, with the ending leaving an opening for one more level. Very heavy on the puzzles... very nicely constructed. Enormous. Author expressed concern that the bar keeps being raised for quality, but he needn't worry just yet... This is another winner.

Tycho didn't die when his ship crashed... and now he's back, and he's pissed. He wants you dead. The levels here are not easy, but they tend to be tough not because of good planning, but because of overwhelming numbers of baddies, and lack of ammo. 6 or 7 blue hunters at a time, e.g. Update adds much better term text, a new level, and some tweaks.

A pretty incredible 26-level scenario from a Danish mapmaker. Quite a bit of new art, as well as art "borrowed" (with credit) from other work... The storyline is conveyed in chapter screens-the terms you find simply contain the secret terms from the original Marathon, in case you missed them the first time around. Some unpleasant tricks are here (save whenever you get the chance, since there are more than a few dead ends), and some silly stuff (pictures of naked women in the marine jail cells, the bobs are now boobs (and pretty well done, too), that sort of thing)

5 levels. Very large, generally quite playable. Lots of symmetry, as well as a bit of carelessness (bad textures in places you don't go very often, etc). A couple are very pretty to look at, and a couple seem to use textures gratuitously (that is, there are texture changes that seem to be nothing more than an attempt to get another texture in).

11 pretty big maps. Generally very well-constructed, but using a huge variety of textures per map (adds to eye fatigue after a while). Flow is usually pretty good, and textures are nicely aligned. Worth a look if you have a group of 4 or more.

A pretty straightforward port of Mars Needs Women. Nice job, overall... The only additions are small, to take advantage of some of the improvements of the M2 engine. The intention was to create an M2 version that stayed truer to the original than most of the existing ports, both in feel and in playability. In that, it is a success.

A symmetrical map using water cannons for rapid movement. Clean, and easy to get the hang of... very fast-paced carnage.
