Well, mostly released anyways. Batman: Arkham City’s official website has put up a smidgen of information regarding pre-order offers for anyone who wants to pick up the game in the United States. Of course they didn’t put any pictures alongside these announcements nor go into full detail about which one will contain at least.
But some news is better than no news and GameStop will be offering the Joker’s Carnival challenge map which sounds like the standard challenge maps that Arkham Asylum had, while Best Buy will have something they are calling the combo pack. Exactly what the combo pack will entail is still unknown. Though there isn’t anything stated underneath their logos, Walmart and Amazon are also shown on the pre-order page so expect more news in the future.
