Batman: Arkham City's The Riddler Does His Very Best Jigsaw Impression.

Batman: Arkham City gives ol' Edward Nigma a bigger role — comparable to that of Jigsaw from the Saw movies. Here's the catch: Nigma's constantly setting Batman puzzles to solve. If you fail to complete them, a resident of Gotham dies. Sound familiar. Yup, it's Saw.

Despite us knowing about some secret showcase at Warner Bros' GDC panel, it sounds like the publisher are being tight with details. While major publications saw the Riddler in action a fortnight ago, they've decided not to supply us (or anyone else) with the trailer they saw. Boo. We've just got the screenshot above to share with you.
