A pressure plate is a door mechanism that appears prominently in Metroid Prime: Federation Force. They are usually set before an important area in a mission, and in a set of at up to 4 depending on how many Federation Force soldiers are deployed. Pressure plates are connected to a door and must be stepped on in order to open the door. A distinctive jingle is heard when the door unlocks. If 4 soldiers are in play, 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.
