Eidos and Warner Bros. are teaming up to create a collector’s edition for the upcoming Batman: Arkham Asylum PS3 and Xbox 360 videogame. The collector’s edition will include a 14” Batarang (complete with stand) that matches the in-game design, an “Arkham Doctor’s Journal” with 48 pages of notes on Arkham’s inmates that comes in a leather dust jacket, and a Behind-the-scenes DVD—along with the game of course. The map will also come with a code for a special downloadable challenge map, entitled “Crime Alley.” We’re not sure if the doctor’s journal will actually contain helpful information for dealing with in-game characters, but considering the style of the game’s art, it should be pretty cool either play—plus we can add information on all of our crazy co-workers to it as well!

Batman: Arkham Asylum is scheduled to be released back into the general population on June.
