For any new peripheral to succeed in the market, it needs a killer app. Seems like Razer found one -- at Intel's press conference at CES 2011, it got to demowith its Sixense motion controller. We were on hand to see it in action, and it looks like the game's tailor-made to take advantage of your precision arm-waving; moving the right stick controls a tractor beam that emanates from the Portal Gun, such that your protagonist can reach though those game-twisting wormholes without sticking her neck out. But don't take our word for it -- see for yourself after the break!
