If you have ever experienced a shooting game with a non modded contoller, then you will understand that it doesnât give you the speed that is needed to most enjoy a shooting game like HALO. Having a modded controller affects the speed that your weapons can be fired under. If you are firing an FAL in MW2 with your modded controller, your shooting will turn out to be the same as a submachine gun. It also makes semi-automatic guns shoot fully automatic. Rapid fire is one of the main features that you get when you use a modded controller with your shooting games.
