Set in 1972 New York City (five year's before the establishment of the graphic novel's Keene Act, which outlawed adventuring by costumed heroes and vigilantes), the video game explores the peak years of Rorschach and Nite Owl's partnership as a crime-fighting duo, fleshing out the backstory briefly touched upon in Alan Moore's original plot.
The game consists of six separate downloadable chapters that can be played solo, with an A.I. partner, or with a friend in splitscreen format (sorry, no co-op online play). Each chapter is built around events and situations referenced in the graphic novel and will include nemeses like Jimmy the Gimmick and Underboss.
