The Milbots , commonly referred to as Mils, are a race of robots and the primary antagonists in the game Metal Arms: Glitch in the System. They were created by General Corrosive, and by extension, Dr. Exavolt to conquer the planet of Iron Star. The entire culture of the Mils is based on combat and aggressive expansion, and by the time of Metal Arms they have nearly completely wiped out the peaceful native Droids of Iron Star.
