Not a standalone expansion. Arkham Horror: The Card Game Core Set and The Innsmouth Conspiracy deluxe expansion required to play.

The fishing hamlet of Innsmouth may soon be overwhelmed by rising tides and swarming deep ones—but in your fractured memory, you’re still putting together the pieces of your time in this mist-shrouded village. As you stare out at the ill-omened shoals and scattered islands of Devil Reef, you can feel a new piece of the puzzle falling into place. You were out there, among the islands, searching for evidence of the Esoteric Order of Dagon…

Within the Devil Reef Mythos Pack, you’ll find the next scenario of the tangled campaign unfolding around the events of The Innsmouth Conspiracy for Arkham Horror: The Card Game. You’ll flashback to your voyage out to Devil Reef three weeks prior—exploring the islands rumored to be haunted by terrible powers, and where you suspect the Esoteric Order of Dagon is hiding something. With the game’s first vehicle-driven scenario and an assortment of new player cards for every class, Devil Reef is a gripping next chapter in your unfolding tale of rising tides and encroaching madness.
