Phazon Harvester Drone
A Phazon Harvester Drone is a heavy duty mining device that is apparently used by the Space Pirates to obtain Phazon. If it spots an intruder, it will fire large burst of Phazon. Its main Sensor Array is vulnerable to attack, but this will only temporarily stun it. When Samus first encounters one, the Anti-Aircraft shield is up, so she cannot destroy it. Once the shield is down, Samus can return and use her ship to destroy it for a Friend Voucher.
- "Man-portable weaponry cannot penetrate the thick hull of the Phazon Harvester. The anti-air weapon system is vulnerable, but overloading it with weapon fire will only disable the drone temporarily. The Pirates converted several Gloiath-class heavy assault drones into Phazon-collecting units. The drone can use its Harvesting Beam Cannon for defense, and is equipped with an anti-aircraft missile defense system." — Logbook "Phazon Harvester Drone" (Metroid Prime 3: Corruption)
