'Criminal Intent' is the book on villains for Silver Age Sentinels. It features dual stats for both d20 and Tri-Stat Systems. As the definitive handbook for villains, it explores the facets of playing an anti-hero, from the qualities of the dastardly to the formation of dark cabals. It covers a villain's methods, including dealing with other villains, disposing of heroes, and undermining with the law. Everything is tied together in a discussion of archetypes, with new character examples from the world of Empire City.
