The adaptation has never been collected or reprinted.
Alien3 was published concurrently with Dark Horse's adaptation of the second Alien film, Aliens: Newt's Tale (June-July 1992), and was followed by Renegade (Aug.-Sept. 1992) and Aliens: Horror Show (Oct.-Dec. 1992).
The story of the comics adaptation exactly followed the plot of the film Alien3, scripted by David Giler, Walter Hill and Larry Ferguson. In it, Ellen Ripley crash lands on the prison planet of Fury 161 and must face an alien with the few remaining inmates on the planet.
