"The Official PlayStation Magazine U.K. may have revealed a few new features about Batman: Arkham City today, including a feature that had been talked about before.
According to their story, the game will be five times the size of the original game, and will give Batman a Grappling Boost to launch him long distances quickly. When asked about vehicles in the game, a Warner Bros. PR representative said that it's "something we'll cover at a later date."
As for multiplayer, it was described that Catwoman could use her whip the way Batman uses his grappling hook. When asked if she'd be controllable in co-op, game director Sefton Hill said he was "not allowed to comment on that."
