Phazon Harvesting is a large open room in the Pirate Mines of the Pirate Homeworld. It appears in Metroid Prime 3: Corruption. The room consists of many bridges that link to walkways at opposite ends of the room, over a deep pit of Phazon ore. Phazon Harvesting is exposed to the Acid Rain of the Space Pirate Homeworld. The metal on the bridges appears to be somewhat resistant to the rain.
