Arkham Horror (Third Edition): Under Dark Waves

About this expansion

Arkham Horror (Third Edition): Under Dark Waves is a large-box expansion for 1–6 players, with an approximately 180-minute play time. It takes investigations beyond Arkham and into the ill-fated Massachusetts towns of Kingsport and Innsmouth.

Cold salt waves, thick coastal fog, and disturbing disappearances set the stage for four entirely new scenarios. Strange lights move beneath the Atlantic, dark things creep along the shoreline, and the pallid villagers of small fishing hamlets go missing with disturbing regularity.

Two new double-sided tiles bring Kingsport and Innsmouth to life, expanding the locations available for your investigations. Eight new investigators join the party, including the drifter “Ashcan” Pete and the letter carrier Stella Clark.

• Two double-sided tiles featuring Kingsport and Innsmouth
• Eight new investigators
• Four entirely new scenarios
• Over 150 encounter and event cards
• New assets, monsters, conditions, and the terror mechanic

Under Dark Waves adds a broad collection of new content to Arkham Horror (Third Edition), drawing on compelling tales from the Cthulhu Mythos. Its encounter and event cards, new investigators, and coastal locations create fresh challenges as the horrors beneath the ocean waves rise into focus.

Whether your investigations lead through the fog of Kingsport or along the troubled shoreline of Innsmouth, Arkham Horror (Third Edition): Under Dark Waves offers a vast undersea treasure trove of scenarios, characters, and supernatural threats.
