About this expansion

Dark Matter is a fan-made sci-fi-horror campaign for Arkham Horror: The Card Game, designed for 1–4 players with a listed play time of 120 minutes.

Your adventure begins in the future, as you awaken from cryo-sleep aboard a seemingly abandoned spaceship: The Tatterdemalion. What first appears to be an isolated awakening soon becomes a deep-space journey across the solar system.

In Dark Matter, the fate of humanity is at stake. Players are drawn into an attempt to prevent the extinction of the human race while confronting a future shaped by the mysteries of a vast and unknowable universe.

• A fan-made campaign for Arkham Horror: The Card Game

The campaign explores a potential glimpse of humanity’s future, bringing the investigative horror of Arkham Horror into a science-fiction setting. Its premise combines cryogenic sleep, an abandoned spaceship, deep space, and an existential threat to create a distinctive cosmic adventure.

Dark Matter is heavily inspired by the Call of Cthulhu supplements Ripples from Carcosa by Oscar Rios and End Time by Dr. Michael C. LaBossiere. Released in 2021, it offers a fan-created campaign for groups seeking an Arkham Horror experience shaped by science fiction, cosmic uncertainty, and the question of whether humanity can survive what lies beyond Earth.
