Move like controls isn't new for Portal 2 as there was a demo at various E3's at Razer's booth with the Hydra setup on the PC. It was pretty cool, but you know, the PlayStation 3 has the Move control set which the Hydra mimics.
Today, a DLC for Portal 2 launches that lets you finally use Move with the game. You can do a few more things with the setup as demonstrated by the video below over the traditional mouse and keyboard setup or a controller setup.
