Normally news of a Portal 2 DLC would be accompanied by the cheering of fans.  Not so much with the MotionPack, which is exclusively bundled with the Razer Hydra motion controller.  The controller sells for $140 but includes a copy of Portal 2 and the MotionPack DLC, which includes 6 new test chambers.  The new levels feature new gameplay mechanics—stretching objects and sliding portal locations around the wall—that take advantage of the motion controller technology.  The Razer Hydra is compatible with 125 other games and is the first piece of hardware for sale on the Steam platform, which could become a trend if it proves successful.  Don’t fret too much if you’re not willing to spend $140 for more Portal 2 levels, as a free DLC is on its way for the summer.
