Under Western Skies: Twilight Trails
This roleplaying game sets paranormal investigations against the backdrop of the American Old West, where cattle drives, shootouts, and posses conceal a secret war over humanity’s fate. Vampires, were-creatures, extraterrestrials, and other incomprehensible beings move through the frontier. Players take the roles of investigators who uncover occult threats and glimpse the larger conflict. The rules include a new Characteristic, additional Skills, guidance for the Referee, an overview of the campaign’s central mystery, and statistics for the major factions involved.
