Add a Circuit to a Weapon

Most weapons can hold a minimum of one circuits depending on the frame used. Simply add the circuit to any weapon at the workbench to unlock this. The earliest opportunity is in Chapter 3, where youll come to the first operational Workbench in the game and be taught the basics of crafting. Facing the bench, look to the wall on your right at the door which you came through. Theres a blue box on the wall with a light (which looks identical to the boxes that used to contain Power Nodes in previous installments). Open it for a circuit, and attach it to any of your weapons at the workbench
