The Elder Gods greet and invite you to participate in trying to save your wretched existence. The stars are aligning soon and only those who have dared to piece together the clues from the mythos know what's coming.

Do you and your fellow investigators have what it takes to save everything? I think not...



You cooperatively work with fellow players (1-6 players) as Investigators to banish the Elder God and his minions by using Moxie (force of character, determination, or nerve) to reduce their health to zero. If you banish the Elder God before he reduces all of the Investigators health to zero you win the game.


Deck building games are card games with a core mechanic that involves acquiring cards and adding them to your deck (your stack of cards). When your deck runs out you shuffle together your discard pile and your newly acquired cards are now part of your deck. Everything you need to play the game is included in the box.


An American author who achieved posthumous fame through his influential works of horror fiction. Virtually unknown and only published in pulp magazines before he died in poverty, he is now regarded as one of the most significant 20th-century authors in his genre. Among his most celebrated tales are "The Call of Cthulhu", canonical to the Cthulhu Mythos.




There are two phases of the game, a planning and combat phase.

  1. In the planning phase, the Investigators activate cards in their hand, research new cards at the Miskatonic University and then ready themselves for final preparation.

  2. In the combat phase, the Elder God and his minions attack the Investigators' health and sanity. Investigators may go crazy or die out right, however, they have a chance to fight back. The Investigators use Moxie to push back the waves of the occult and supernatural.

Building your personal library by researching in the Miskatonic University makes you stronger and is your only hope against the Elders. Keep in mind, every bit of resource used to research is a bit not used to fight off the Mythos. It is a balance you must solve to defeat the Elder Gods.

Good luck...




The following are clarification on specific cards or card combinations not covered in the Instruction Journal.

For questions not covered here please join us in our official forum over on BoardGameGeek.

  1. When directed to "Draw a Card", is that always from the Personal Library, rather than the General Library?

    Yes it always refers to the personal library

  2. The boxer says to double the effectiveness of Action cards, does that mean double all numbers? Or only beneficial numbers?

    All numbers, beneficial and detrimenal

  3. When the Librarian borrows from the Miskatonic Library, do you only refill it to 4 after she goes to account for this?

    That is correct. She returns the card to the library during clean up.

  4. At the end of the round, the rules suggest discarding unwanted cards from the Miskatonic Library, is this actually whatever cards the players don't want to obtain in the future, leaving whatever is desired?

    That is correct, you would basically destroy them and then replace them with new cards.

  5. It would seem that if both Cthugha and the Voodoo Doll are in play there would be an infinite loop.

    It does not create an infinite loop. The damage done to the Investigator will also be done to the Elder Gods. If Cthugha is one of the Elder Gods that damage is also done back to the Investigator. That damage is NOT reflected back again.

  6. Mystic Binding lets me take control of Minion so they fight for me, but how exactly do they do that?

    In the text of the Minion replace the word "Investigator" with "Elder God." The captured Minion activates when the minions activate.

  7. Incorporeal Daemon reduces the cards I get to draw in the planning phase. If there are five of them active is my game effectively over?

    In this case the Investigators always get to draw a minimum of one card despite their effect.

  8. For the Doctor Investigator, what are considered bladed implements for my special ability?

    The bladed implements are considered the following library cards: Katto, Dagger, and Shank.

  9. The Unholy Abomination indicates half of the damage is reflected back to the Investigators in Sanity damage. What if I do an odd amount of damage?

    Always round up. For example, if you attack the Abomination with 3 moxie, he takes 2 Health damage and 2 Sanity damage is reflected back to the Investigator.

  10. For the card R'lyeh do all Investigators get the +2 Moxie and -2 Sanity or only the Investigator playing the card?

    An Investigator will gain 2 Moxie and lose 2 Sanity for each card they played. It wasn't intended to go to everyone.

  11. When a card calls for a source to declare to avoid damage, what are the sources I can declare?

    You can declare: Elder God, Mythos, or Minions as your source. This applies to all of the cards played of that type in that round.


The following are corrections to the cards and instruction journal for the 1st printing of the game. These have been corrected in the 2nd printing.

  1. Consume

    The description reads, "Spawn 1 Beh'moth the Devourer."
    It should read, "If not already active spawn 1 Beh'moth the Devourer."

  2. Necronomicon

    Has a cost of 5. It should be a cost of 8.

  3. Time Traveler

    The Time Traveler has a special ability that reads, "Gains a +1 effectiveness on all Starter cards" This should read, "Gains +1 Moxie on all Starter cards."

  4. Loathing

    This card should be treated as "Permanent."

  5. Green Jade Amulet

    This card should be treated as "Permanent." The text on the card should read, "Each Investigator loses their Special Abilities.

  6. End of Days

    The description on this card reads, "The next Elder God activates and both are active at one time."
    It should read, "Another Elder God is activated. This Elder God must also be defeated to win."

  7. Investigator Healing

    In the Instruction Journal page 10 under the section labeled Healing it reads, "All Investigators have the power to heal both Health or Sanity during the Preparation phase. Investigators may use two Moxie to heal one Health or Sanity."
    It should instead read, "All Investigators have the power to heal both Health or Sanity during any phase. Investigators may use two Moxie to heal one Health or Sanity."
