Cultistorm is a Cooperative Weird Fiction and Cosmic Horror Board Game in the universe of H. P. Lovecraft.

Cultistorm is the expression of our respect and love for H. P. Lovecraft. It is more than just an ordinary board game – this is a Lovecraftian gaming experience with literary and musical dimensions. Our theme choice was motivated by a deep commitment to the work and heritage of H. P. Lovecraft. We want to create an excellent board game for those who know and love Lovecraft, and we would like to make Lovecraft’s work known to those who are board game fans.

Each round of Cultistorm consists of 6 phases where players combat cultists and try to close 5 portals. The game is lost if any of the following happens:
● Any investigator goes insane.
● Any Great Old One reaches a location card.
● The number of cultists exceeds the cultist threshold.
● The investigators do not manage to seal all the locations before they defeat every Great Old One
after the activation of the Final Act card.

Additional expnsions include:
- Narrative Expansion and Script Book: the true jewel of Cultistorm is a hardcover book containing 500+ pieces of high quality weird fiction, illustrated with colourful full-page artwork. The Narrative Expansion is a story-driven game mode in which the stories impact the game itself.
- Solo Expansion for those solitary detectives who wish take up the fight on their own.
- Campaign Expansion: seven connected and increasingly challenging scenarios introducing new game mechanics.
- Overlord Expansion: this adds a sixth player who takes on the role of Lovecraft himself. As a puppet master, this player controls the cultists, and thus the whole game.
- Nine minor expansion modules: each of these introduces new game mechanics, increasing the replayability and difficulty of Cultistorm. Most modules can be played simultaneously.
- Game Night Expansion (as add-on): this unique and innovative expansion provides the possibility of combining up to six separate Cultistorm games into one epic story. A common fight, in which the choices of the different teams can impact each other. This expansion was developed specifically for clubs who organise board gaming events.
