Hardware (1990) 1080p aka M A R K -13

In the desert wasteland of a post-apocalyptic future, a scavenger known as a "Zone Tripper" discovers some robotic remains which he sells on to a marine returning home from an off-world tour of duty. After failing to negotiate a decent price with a local junk dealer called Alvy, the marine, Mo, decides to give the dismantled robot to his girlfriend Jill as a Christmas present. But as she begins to use the wreckage in a sculpture she's been working on, a frantic call from Alvy brings Mo back to the junk yard, where he discovers that the robot is more than just a service droid; it is a MARK 13: a military robot suffering a major design fault that rendered it a deadly killing machine. But worse than that, the Mark 13 is capable of self-repair. With Jill trapped in her apartment, the terrifying fight for survival begins. Will any flesh be spared?
