From the publisher's website:
A setting for different BASIC ROLEPLAYING genres. Includes information on life in the city during the cold war, key locations, and special organizations. Battle spies, assassins, cultists and the Dark Herald Kototh. A great back-drop for espionage adventures in the 1960s style, and silver age superhero action!
