Into the Maelstrom is the sixth expansion in The Inssmouth Conspiracy campaign for Arkham Horror: The Card Game.

During your Innsmouth explorations you've ventured into tide-hollowed caverns and dripping tunnels - but these watery caverns are but the antechamber to the Deep Ones' domain. A hidden city lies beneath the choppy waves of the North Atlantic Ocean, dormant at the bottom of the ocean. If you want to protect the world from the same fate as Innsmouth, you must venture into the heart of the storm.

In this Mythos pack you'll find the final scenario of The Innsmouth Conspiracy cycle, inviting you and your fellow investigators to delve into the darkness beneath the waves and confront the Deep Ones in their own city - ending it forever meets this threat. Combined with the addition of new player cards to upgrade your decks, Into the Maelstrom is a perfect capstone to a cycle of danger and mystery.
