Our demo ended with Batman descending upon a rooftop as his Cyptogram device was picking up a strange signal. He stops in front of a large billboard, the words "Turn on and Tune in Before Someone Checks out - 275.00 325.00" crudely scrawled on its face. The Dark Knight jacks into that particular frequency and we're given our first glimpse at Arkham City's darker, twisted vision of Riddler.

How Riddler encounters and missions will play out is still very much an enigma itself; Ginn would only confirm that he'll be both physically threatening Batman and "the lives of innocent people." From the sounds of things, the critical narrative path will have you dealing with the likes of Two-Face and Joker. But Ginn was hesitant to call Riddler encounters "side missions."
