Arkham Horror LCG: In Too Deep je prvé rozširenie v novom cykle The Innsmouth Conspiracy. Na hranie budete potrebovať základnú hru Arkham Horror: The Card Game.  Toto rozšírenie spoločenskej hry Arkham Horror: The Card Game je v angličtine a tento jazyk je na jeho hranie potrebný, preto aj popis ďalej uvádzame v anglickom jazyku: Since awakening in a dank and dismal pit on the Atlantic coast, your memories of your time in Innsmouth have been scattered and difficult to piece together. Why did you come to the town of Innsmouth? What exactly transpired between your arrival and your nightmarish experience in the tidal tunnels? What is the connection between the Esoteric Order of Dagon and the swarming deep ones? These questions and more will have to wait—Innsmouth may already be slipping beneath the waves! Within In Too Deep, the first Mythos Pack in The Innsmouth Conspiracy cycle for Arkham Horror: The Card Game, you’ll find the next chapter of the story, drawing you deeper into the tangled web surrounding your visit to Innsmouth. It’s not just a new scenario, however—you’ll find new player cards to support every class, including powerful new Covenants that center on the bless and curse tokens introduced in The Innsmouth Conspiracy deluxe expansion. This is not a standalone product. A copy of the Arkham Horror: The Card Game Core Set and The Innsmouth Conspiracy deluxe expansion are required to play.
