G.I. Joe: The Rise of Cobra

Firefly Appears at the end of the 5th Desert Mission. I don't have any real strategy on beating him. I just kept hammering him with everything I had. After a few hits he Disappears then reappears on an upper platform and cuts the power to the Power Cells. Recharge the cells and take out a few more cobra troops that appear then he reappears again. Wash and repeat this process til two of the Cobra Remote Drones appear. Take out the drones, take out Firefly.. end the Mission. Yo Joe!
