Update: official trailer released, and below, right at the very bottom of the post. First there was Batman: Arkham Macguyver, then there was Batman: Arkham A Bit Of City, then Batman: Arkham Oranges, and now there is Batman: Arkham Nighty-Night. Oh, alright, just Arkham Knight. But I'm only calling it that this once.And it has a driveable Batmobile! Jeez guys, why'd it take you four…
