"Top Line", a.k.a "Alien Terminator" (1988), with Franco Nero
Full movie is on Youtube here:
Right at the end of the movie, ca. at 1:26:26 you can see the natives in the jungle with the small, clay spaceship, and the spaceship is shown as the end credits roll. And near the end of the movie, Franco Nero fights with the cyborg dude. At ca. 1:12:26 there is a close-up shot of the cyborg's face, half of it damaged, like Arnold's face in The Terminator. The scene where the sexy woman transforms into the alien creature near the end of the movie starts ca. at 1:20:00. The movie is set, and was shot, in Colombia.
