A pressure pad is a door mechanism that appears prominently in Metroid Prime: Federation Force. They are usually set before an important area in a mission, and with a set of four pads, which must be stepped on to open the door. A distinctive jingle and click is heard when the door unlocks. If 4 Federation Force soldiers are in deployed, all 4 plates will need to be activated before they can proceed; this number lowers if there are 3 or less soldiers. This is for balancing purposes. It also makes them similar to the Extractor that is deployed at the end of a mission. Pressure plates are present on all three planets in the Bermuda System, in most of the game's missions.
