Hey guys, I've been looking into the XCM XFPS 360, but I need a Mouse/Keyboard device which properly matches the orientation of the regular movements. In other words, I need the character in the game to move as fast or as slow as I move the mouse, not at a fixed pace. Is there anything you guys would recommend?

Yes its called a controller.

Not to be smart, but you dont have much of a choice of using anything but a controller as from what I have seen the XFPS 360 is not that good and very inaccurate and thats the only device of its type out there
