"When spaceship Remus crash-lands on planet Morganthus, the Planet Master of Xerces sends the spacecraft Quest to rescue them, but it crash-lands, too. Baelon leads the away team, comprising himself, his rival Cabren, psi-sensitive Alluma, medic Dameia, martial arts fighter Quuhod and jittery rookie Cos. Finding only brutally murdered bodies aboard the Remus, Quest personal start getting brutally slaughtered, one-by-one, themselves. With their ship still damaged, the team investigates a nearby, lifeless alien pyramid, not realizing its using their own personal fears to hunt them down and kill them."
I think I heard the production designer went on to do some stuff...

@Anorack So yes, this is a cash grab piggybacking off Alien (and maybe a bit of Battlestar Galactica), but IMO it's a pretty respectable pulp sci-fi film that transcends its limitations and is enjoyable on its own terms. Sid Haig turns in a respectable performance, Ray Walston is terrific, and the ending is pretty great.
Also, James Cameron (yes, THAT James Cameron) was production designer and second unit director.
And: what an amazing poster.
