Someone better get ready to catch Elliott when he faints because Fantasy Flight Games has announced a surprise for Gen Con attendees: a previously undisclosed Mansions of Madness expansion. The expansion is entitled The Silver Tablet and there isn’t much info to be gathered just yet but we do know the expansion will be available for sale at the convention and will make it’s way to stores soon after. Game Salute has an image of the expansion box if you’d like to take a quick peek.
