A large level with a few open areas, a suicide room, and lots of passageways that look the same. The room with the fluctuating pool has some neat features, though...

Two huge rooms (lots and lots of smearing) filled to the brim with aliens, and bobs, and S'pht'Kr. No weapons... you're supposed to do your fighting with what you can pick up off the dead bobs... Frame rates below 5 fps on a Q800.

Two levels. One is a conversion of Bob World HQ (no credit to Mark Conahan, the original creator), using the alien textureset, and the other is a small insanely busy arena with a raised cross in the center.

An arena level with a large pool in the center. Half of the bottom rises and falls slowly, making a good high spot (or missile block). Teleporters speed up end-to-end travel, and light switches control who's visible and who isn't...

The net level included with the Infinity demo, for those of you unwilling or unable to download the 19 meg file yourself. The only change was Type code, so that M2 would recognize it. Otherwise, it's the same as the Infinity level.

A large map, broken into a few rooms. Lots of ledge shooting... and doors that look like walls. Should boil down to an arena map, with a few areas to take breathers in.

A large, two-level arena. The hill is elevated, and can be reached from walkways at all four points of the compass. Travel between the floor and the upper areas is well-facilitated, and in general, flow is quite nice. The hill's big enough that you can dodge almost anything coming at you... in order to knock someone off, it'll be necessary to get on it yourself. Update tweaks alignment and object placement.

A sequel to Operation: Exaggeration. 12 levels (or so... a couple don't really count, in terms of gameplay). This one's a winner. It's not the most visually stunning, or the hardest... but the AIs are very funny, the physics are brilliant, and the tributes are really, really well done. Don't miss this map-it'll give you ideas for your own maps. (And the sense of humor shown in the storyline is really refreshing, after all the 'save the universe'-type plots.)

The third installment in the Origin of Species series. Definitely up to the standard set by the first two chapters... with very nice term art, and some hellishly good level design, this one should satisfy the Tony Smith cravings induced by previous releases, at least for a little while...
