Nah, it's been our of print for thirty years or more. Alien was the first in a short lived line of Heavy Metal "Illustrated Story" movie adaptations, which would be simultaneously serialized in the magazine and released in trade paperback. The second was an adaptation of Spielberg's 1941 by future Alan Moore collaborators Rick Veitch and Steve Bissette. (Needless to say, many liberties were taken with that adaptation, and the result was much more entertaining than the actual film.). There was a third adaptation, this time of Peter Hyams' Outland by Jim Stetanko, but I don't think there was any book version. This was clearly in response to the success of Marvel's movie tie-in comics like Star Wars, but whereas they were limited to family friendly films with sub-PG level dialogue, the HM versions were free to be as profane and gory as they pleased, with all the nudity and cussin'.

Incidentally, the Alien book was the first graphic novel to reach the NYT bestseller list. Why Dark Horse hasn't tried to secure the rights is beyond me.
