Arkham Asylum Collector's Edition Contents Announced - PC, PS3, Xbox 360

Atari have filled us in on what you'll get in the Collector's Edition of Batman: Arkham Asylum when it arrives in stores this Winter. We've also got a brand new trailer debuting Harley Quinn, which you can download below.

First, you get two discs - one is the game, obviously, while the other is a behind-the-scenes DVD. There's a code for the exclusive, downloadable 'Crime Alley' Challenge Map, an Arkham Doctor's forty-eight page journal of notes on the asylum's inmates, and a full-colour manual. The pièce de résistance, though, is a fourteen inch Batarang with stand that matches the weapon's in-game design. Check out the image below.
