"During a routine flight, two veteran space shuttle pilots discover an alien artifact and bring it back to earth. It soon turns out to be an extraterristial war robot, which is able to recycle any biological or technical material for its own deadly use. The two astronauts are sent to the moon where Nasa expects to uncover the mystery of the alien robot's origin. They discover an ancient humanoid culture and battle the ultimate threat of the war machines heading earth."
Sci-fi horror from 1989 starring Walter Koenig (Chekov from Star Trek and Besther from Babylon 5) and Bruce Campbell (!). It's a VHS rip, because as far as I know, this movie has never been released on DVD.
