Our American Cousins
This roleplaying sourcebook explores American intelligence operations during the turbulent 1970s, covering the final years of the Vietnam War, domestic extremism, foreign revolutions, terrorism, and congressional scrutiny.

The book includes 1970s setting material, characters, plot hooks, Mythos threats and Fortean events, information on American intelligence agencies, useful non-player characters, and the complete Cold War Europe adventure “Brocken Spectre.”
