The game follows a robot named Glitch as he joins forces with the Droids in their fight against General Corrosive and his Milbots.

The Morbots are rumored to still inhabit Iron Star's core, where none of the surface dwellers venture for fear of deactivation and destruction.

Glitch aids in the defense of the city and pursues a Mil, Vlax, that got away, so he could not report the location of Droid Town to General Corrosive.

As Glitch searches for Zobby, he takes control of General Corrosive, and initiates the permanent shutdown of the Milbots.

Glitch is received as a hero for destroying the Milbots, while Exavolt, watching from his shuttle in orbit, vows revenge.

Metal Arms: Glitch in the System was developed by Swingin' Ape Studios and published by Vivendi Universal Games on November 18, 2003, in North America for the GameCube, PlayStation 2 and Xbox.
