so in my constant learning curve of MP .... i have recently uncovered the world of modded controllers which range anywhere from a controller with a fancy paint job to a controller that has 20 modes built into it ... ranging from faster shooting, auto-aim, drop shot, faster reload, etc. anyway what i am wondering is do these "modded" controllers really help the FPS MP games ?..... how do they work? ..... are they legal? ..... i know they ain't cheap ....... has anyone ever tried them?
