Green Lantern Blu-ray includes Batman: Arkham City costume

Sometimes, DLC can pop up in the strangest of places. Purchasers of the upcoming Green Lantern Blu-ray will receive a rare costume for use in Batman: Arkham City. Green Lantern is coming to Blu-ray on October 14th, just a few days before the release of Arkham City. In addition to an extended version of the film, the disc will unlock the "Sinestro Corp" skin for Batman. "The skin will give users the ability to fight crime with the help of the yellow power of fear, giving Batman a unique yellow costume in the story campaign and in the challenge maps," Warner Bros. explained to IGN.

The DVD release will not feature this extra, making this a PS3-exclusive bonus. It's not the Joker, but it's something, right?
