Left 4 Dead 2 Motion Control Video

Using a single transmitter with a six-foot radius range, Sixense TrueMotion can detect the position and gesture movement of controllers without a line-of-sight limitation. As long as the controllers are within the 12 foot diameter spherical magnetic field, it can detect their movement in space along six axes. This looks like a big fat pain in the ***, or magically cool, time will tell.
