Portal 2 Sixense MotionPack DLC

The Portal 2 MotionPack (for PC) or Portal 2 In Motion (for PS3) is exclusive Portal 2 downloadable content available to owners of the Razer Hydra or the PlayStation Move. The DLC includes specific Singleplayer and Cooperation levels (created by Danny Woodall and Chip Sbrogna) and mechanics that make use of the controller's motion detection capabilities. Razer has discontinued to sell the Hydra via their own and Steam's online store due to Sixense's upcoming Wireless STEM System.
