We all know that the Riddler will have a much stronger, and more physical presence in Arkham City, and now you can see how that will be. In this very interesting, and disturbing trailer, we only see a few glimpses of the gameplay, some of which show the Riddler in his hologram form — the new way he contacts the Batman. The rest of the trailer consists of the Riddler’s voice, plus many, many equations for who knows what. But, according to the Arkham City Twitter feed, there a few riddles hidden within the trailer, so maybe solving, or identifying these equations may help us on the way.
Watch the video here, and see if you can solve, or spot any of the riddles.
