Not a standalone product. A copy of the Arkham Horror: The Card Game core set is required to play.

In the shadowy, decrepit seaport of Innsmouth, a tangled scheme begins to unravel. A government agent goes missing. Strange creatures are sighted by the reef along the coastline. Celestial bodies align. And, caught in the center of it all, several outsiders awaken in a deadly pit with no memories of how they got there or how to escape.

In The Innsmouth Conspiracy Campaign Expansion, one to four investigators take search for their missing memories and the truth about the rumor-haunted town of Innsmouth. Flashbacks offer the investigators insight into past events, and may even influence the future…but do they really want to know the truth?

This expansion combines all of the campaign and scenario content from the original The Innsmouth Conspiracy cycle, which was the sixth cycle of expansions for Arkham Horror: The Card Game. Players only need a copy of the Arkham Horror: The Card Game Revised Core Set to dive into the story.
