The Metal Fabricator is a small room off the right side of the south Arbitress hallway. In this room the android can be rebuilt by stepping on the red control circle with the Memory Card in your inventory. This then replaces the card with a remote control. The android can also come here to be upgraded into either the Surbeit Chassis or the Valkyrie Chassis by stepping on the pad at 22 minutes or 2000 EP.
