Please help!! Looking for sci-fi horror movie

Hi, im looking for a Sci-fi movie... i dont know what it is called, i only vagely remember some scenes, i was like 5 yrs old when i saw it. the movie, as far as i remeber, takes place on a moon-like planet, we follow 3 persons a woman and 2 men.

The first scene that i remeber takes place in a tent, the woman and one of the men is in it, they have lost the 3 guy. All of the suddent, the lost guy rips through the tent, hes transformed into this half man/Half robot.

Another scene: the man and the lady walks into this big room, filled with tall cylinders, that contains human-parts

Its not much, but i really hope that you guys can help me
