One of my personal qualms with Batman: Arkham Asylum was a lack of payoff for completing the lengthy Riddler challenges, with the game not offering a glimpse of the maniacal genius in his moment of capture. As of today, the Riddler's absence has been rectified.

While his role in Arkham City is still thickly veiled, a recent demo at GDC confirmed that Edward Nigma will play a larger, darker, and visible role in the game. Taking to the rooftops, we witnessed Batman use his cryptographic sequencer to pick up on a radio signal scrawled across a billboard. Tuning in on the numbers ushered in a cutscene in which E. Nigma gave us a peek into his unstable world. He taunted Batman incessantly over images of human captives, illustrating that he has upped the ante this round.

Yesterday we learned that the Riddler trophies will return, but with a catch. Now, instead of decoding riddles Batman will have to track down goons that have information on the item’s location. Many of the trophies will be booby trapped, too.
