The U-Force is a NES controller that you use your hands to control. There is also a flight stick with two shooting buttons for other games but not only for flight games. There is also another add on for Mike Tyson's Punch-Out!!, a power bar which enables punching the air in front of the controller to simulate punching in the game. This controller is often voted one of the top 10 worst gaming controllers in history because it was way ahead of it's time and it was too big and bulky. This article is a stub.
