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.
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.
Another modification of Waldo World. New textures, light switches, a control room, a teleporter maze... Not a bad job at all. (May need more players to be fun than Waldo World does, owing to its larger size.)
