Only works with Ultimate Doom, is compatible with GZDoom, Skulltag, Zandronum, and ZDoom
Im just uploading the mod here so people can find it easily.
Here is some intresting information from Wikipedia:
Aliens TC by Justin Fisher, based on the movie Aliens, was the first total conversion for doom (infact the first total conversion for any game) and is one of the most famous. in the week following the release of Doom II, there was more discussion in the Doom newsgroups related to Aliens TC than Doom II. The popularity of the Aliens TC even reached outside the Doom community, for instance providing inspiration for the 1998 Dreamworks game Jurassic Park: Trespasser. Fisher was offered employment by various game developers (including Dreamworks for the team that would later make Trespasser), but declined in order to finish his university degree.
