Unidentified Artificial Mechanism 3 is an unknown model of turrets used by the Space Pirates. Encountered in the Scrapworks, it works by targeting objects that only move along certain sections of tract. Whether it is exclusive to the Space Pirate Homeworld is unknown. A similar design of turret is employed by the rogue Aurora Unit 313 during Samus' battle with the creature on Phaaze. However, this turret fires a different projectile.
