Heavy Rain will receive a free patch on September 22 to support the Move peripheral. The PlayStation Blog notes the patch will download automatically when users start the game, adding actions that "mimic real-world motions" -- like knocking on doors (pictured). For those interested in experiencing this, you'll have to pick up the Move controller on September 19.
The PSN will also add a Heavy Rain Move demo on September 28, featuring two of the early levels in the game. As the update is all about adding Move support, don't expect a pronunciation patch for "ore-A-gammy killer."
