User summary: Los Archivos Arkham presents a fairly generic Cthulhu Mythos setting adapted to the rules-light Carne Fresca game engine. The intent is to provide an easy-to-access and easy-to-play experience in the Cthulhu Mythos. Advanced familiarity with the Mythos is not required, and - as with all Carne Fresca scenarios - adventures are intended to be "one shot" sessions. The product is in Spanish.
