Times are dark and sinister agents move in the shadows. Can you stop the Elder Ones from awakening? In this 2-player asymmetrical card game, one player investigates several locations for indications of Cultist activity. Facing maddening dangers and grotesque specters, the Investigators duty is two-fold - find out what horrors lurk in the shadows and stop them. Be clever and investigate rumors to gather insight before the cult can awaken an Elder One. The Cultist sets perilous traps, summons fearful specters and casts reality warping spells to prevent the Investigator from discovering the secrets of the Elder Shadows. Each player is given a set amount of action during their turn to use as best they see fit. Will you draw cards or Investigate? Will you summon a Specter or set a trap? In a devious twist to standard card games, Elder Shadows implements a unique Sanity system making all cards more, or less, powerful based on the current Sanity level. Can you expose the Cult before they can open the gateway to unimaginable horror?
