Today Eidos has detailed the upcoming Batman: Arkham Asylum DLC pack, "Insane Night."

On September 17th (on PS3, PC and 360), you'll be able to download the "Totally Insane" combat challenge, which pits the Dark Knight against escaped lunatics in Arkham's records facility, as well as the "Nocturnal Hunter" predator challenge, where you and Bats will rely on the shadows of the Arkham watchtowers to remain hidden.

Best of all, they'll both be available for the bargain price of nothing.
