Following the events of The City of Archives, your team of investigators find yourselves trapped deep in the of the Earth and the only way out is...down. Your mission to protect humanity continues, but the threats to your life increase with each level of the descent. There is no telling what monsters have grown in these dark caverns and now pursue your team, but you cannot look back, or you are surely lost.
This Mythos Pack features new player cards to customize your investigators' decks and treacherous encounter cards to immerse you in the peril of your investigation. This is not a standalone product. It requires a copy of Arkham Horror: The Card Game Core Set and The Forgotten Age deluxe expansion to play.
