Anybody heard of the XIM3? They have two newer versions out, number 4 and some other doo hicky. Anyway it's an input converter that translates the movements of a mouse to the xbox 360, so you can use a mouse and keyboard to play. It won't turn you invincible but it's a major advantage. I justify the use by saying that I still rape train people with a regular controller, but lemme tell you it's awesome. You may now throw your hate messages at me for "semi-cheating"
