An extractor is a drop ship attachment used by the GFMC in Metroid Prime: Federation Force. After completing a mission, the Federation Force must proceed to a certain location of the area where this extractor will collect them. The extractor is an oddly-shaped apparatus that locks in Marines in a similar fashion to a seat belt, and then ascends into the Marines' ship. In missions where the Force is recovering cargo, the Extractor will be found inside a landed cargo ship, which they can use to lift the ship off once the cargo has been dropped off.
To strap into an extractor, the A button must be held down for a few seconds. In front of every "seat" is a light, which changes to the corresponding color of the Marine when they strap in.
