To beat Duo, the chips in your folder should run smoothly, not having too many codes, and you chips should be above ground attacks,such as wide shot or life sword. Gun Sol chips are extremely effective against Duo, adn you should have 3 or four Invis* chips. Duo has four main attacks, one is the big fist that covers 4 squares. The others are the Duo Laser, meteor fist and the giant Arm that covers 6 squares. The laser is easy to dodge, all you have to do is go to on of the side rows and dodge the rings by moving foward, then back and foward again. The giant arm covers 2 rows so you would stand in the first row and then move back because he's going to hit again. The meteor fist has no specific place that you can dodge::best way is Invis.
