The Phazon Processing Center is a large room in the Phazon Mines in the game Metroid Prime. This room, as its name implies, contains a lot of Phazon in the lower level. The center is full of Trooper Pirates and, in the PAL and Wii versions, after the Omega Pirate has been defeated, Fission Metroids appear. The main purpose of this room is to provide a shortcut to the Magmoor Caverns.
