There was a lot of speculation going around rather Robin will be a playable character in Batman: Arkham City.  He will, in fact, be a playable character in the game.  Best Buy teamed with Warner Bros for the perk if you pre-order the game.  However, for gamers who were dreaming of co-op with Batman and Robin; keep dreaming.  Robin will only be playable in two challenge maps.  Me personally, I don’t really like Robin, but I am interested to see how they will portray Robin.
