Picks up where Encounter:Colony leaves off. Your job is to clean out a Pfhor ship with the help of some crack marines. Requires Enter the Marines shapes patch (included). Not all that hard, unfortunately...
Pretty big (looks like you'd need four or so for comfortable net play), but really well done. Some very nice features (polished crushers, e.g.). A little of everything...
Three maps, and a physics model that bumps up the aliens' skill without changing your abilities. Inspired by 20 Minutes of Hell, these are good for those times when you just need to waste some Pfhor...
Butch said he was done with these, but he lied. Three more levels, one modified bungie and two original. Pistol Parlor gets some nice action with pistols as the only weapon...
Another scenario by the creator of Luna West. This one has some pretty serious bugs... I almost didn't put it up, but I figured if enough folks emailed the author, they might get fixed. Worth a look, anyway... Non-linear.
