Arkham Horror RPG: The Thompson Files

Beneath the paper-thin skin of our reality lurk monsters whose horror defies imagining…

This supplement features Mandy’s collaborations with nine other famous investigators such as Silas Marsh, Trish Scarbrough, and “Ashcan” Pete as they research over 50 eldritch horrors; both infamous and hitherto unknown. In the collection of notes and documents you’ll also find each of these investigators’ own observations on these creatures’ habits, dangers, and weaknesses, as well as nine mini mysteries to help you incorporate these abominations directly into your game!
