Aliens TC is a total conversion based on the movie Aliens, created in 1994 by Justin Fisher. It was the first total conversion 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 to Doom II. The popularity of the TC even reached outside the Doom community, for instance providing inspiration for the 1998 Dreamworks game 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.
