Grab your raincoat and hold your lantern tight, because the investigation in Arkham has just gained a new and sinister horizon! In 'Under Dark Waves', the fog isn't just rolling through the city streets; it's descending from the mountains and rising from the depths of the Atlantic to swallow everything in its path. If you thought the town of Arkham was the only place where the supernatural knocked on the door, get ready for a shock: we are expanding the map to neighboring Massachusetts towns, bringing the decaying charm of Kingsport and the unsettling atmosphere of Innsmouth straight to your table.

This large-box expansion is a true feast for cosmic horror enthusiasts. You won't just be exploring new territories with double-sided tiles; you'll also have new faces to trust (or not!) in your crew. Eight new investigators join the fray, ranging from the drifter 'Ashcan' Pete to the dedicated letter carrier Stella Clark, each bringing unique skills to manage the chaos. And don't think the danger is strictly land-based; with four brand-new scenarios, the horror now arrives accompanied by dark waves and undersea mysteries that will make anyone question their own sanity.

The content is massive: over 150 new encounter and event cards, along with a flood of new assets, monsters, conditions, and items. A major highlight is the introduction of the terror mechanic, which cranks the tension up to an almost unbearable level. If you're already a fan of the third edition, this expansion is the essential fuel to keep your game nights filled with adrenaline and despair. Just remember: the ocean holds secrets that humanity was never meant to unearth, and in Under Dark Waves, the tides don't just bring salt—they bring the end!
