3 maps. Nearly impossible solo (too many aliens, not enough hiding places), but some nice flow mechanisms for net play.
7 levels. Quality really varies. Some are quite fun, though... Quag's Keep was very enjoyable, and the last level is just about impossible at normal.
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.
