Arkham Horror: The Card Game – The Innsmouth Conspiracy: Expansion*
The Innsmouth Conspiracy is the sixth Deluxe expansion for Arkham Horror: The Card Game. It adds a time-bending campaign, five new investigators and a deep stack of player cards. You need the Arkham Horror: The Card Game core set to play it.
What is it about?
Not far from Arkham, the weathered town of Innsmouth clings to the Atlantic coast. Decay hangs over everything: the eerie glowing windows of the Gilman House, the collapsing Fish Street bridge, half-flooded tidal tunnels beyond the town line. Nobody wants to learn what waits among the fish bones and rotting seaweed.
What's in the box?
The expansion opens the Innsmouth campaign and brings plenty besides:
- The first two scenarios of a campaign that continues across six Mythos packs
- Five new investigators with their own card pools
- A wave of new player cards for fresh deck types
- New tokens: keys, flood, blessings and curses
Who is it for?
Made for groups already comfortable with Arkham Horror who want a connected story. The flood mechanic adds pressure and new puzzles to solve. It is not a starting point for newcomers, since nothing here works without the core set.
Conclusion
If you love Arkham Horror and want its next big campaign, buy it. New players should pick up the core set first.
