as good as a mouse and keyboard may sound for console only shooters, this wont be very good. Console only games tend to have button combinations and sensitivity movements that arent well played on mouse and keyboard. I remember playing splinter Cell 1 on pc, and changing walking speed didnt feel right at all(speed was controlled by the scroll). For some games a controller works better, because pc may have precision on the aim, but consoles have more comfortable precision on movement.
And button mapping on this would just be a drag.
