Portal 2 In Motion is a new DLC pack dropping on PlayStation 3 later this year.
According to a Sony representative, In Motion contains some of the same levels that were previously available for Sixense's Razer Hydra controller. Players can rescale cubes, exhibit "one-to-one control of objects," and reorient set portals ("portal surfing") to solve puzzles.
In Motion features 20 test chambers and will use the PlayStation Move. Players can choose between Atlas and P-Body.
Sixense also plans to bring Move support to the regular Portal 2 experience on PS3.
