If you want to be Batman and beat up skeletons, you might want to take into account pre-ordering Batman: Arkham Asylum with GameStop.

Those who pre-purchase the game with the retail will receive access to an exclusive Scarecrow “Challenge Map,” called “Dem Bones.” It’s there that Batman will get to beat up skeletons. Because skeletons are evil. We also have to take GameStop’s word that the level will be one of the most difficult Challenge levels in the game, “in true core gamer fashion.” Core gamers do like beating up skeletons; I know this because it’s true.
