Quite large, or so it seems. The package is so big because the author has included all development versions of the map, along with films for each version.

Three maps, 5 levels. One three-pack, normal. The other two are variations on the same map. They both require the textures from the Canyonlands package, and the second one was designed with the Dogs of Pfhor package, as well.

Very simple map. You're on the roof of a skyscraper, with lots and lots of weapons. Fall off, and die.

6 levels (The title level, and 5 bonus levels). Pretty well made, small but not simple. The bonus levels seem to be experiments... some work really well.

The very beginnings of a Doom port. (Currently listed as v0.5.) Wait and see...

Set between Arrival and Bigger Guns Nearby, this level expands on the Bungie storyline. Another strategy level-your only weapons are your pistol and your fist. Nice.

Four levels. Exactly what they sound like. Each level consists of a room with one or two specific types of aliens in it. The included physics model simulates a hydrogen-filled atmosphere-use your gun and die. The idea here is to get good at killing with just your fist, and to stay alive as long as possible. Just 20 minutes a day, 3 days a week, and you'll have a flatter tummy in no time.

Huge. Lots of juggernauts, hulks, etc. Had a few bad polys, which I fixed... comes with a film showing the creator and a buddy getting wasted by aliens.

A very simple map, but with a lot of potential. You start at the top, outside, and the only way to go is down and inside... very little room to maneuver, so he who shoots best wins.
