Against the Storm - Keepers of the Stone is DLC for the city-building strategy game Against the Storm. It introduces the Frog species, who possess unique housing requirements and a proficiency in stone masonry. The add-on also includes two new biomes: the Coastal Grove, accessible via the Strider Port for underwater expeditions, and the Ashen Thicket, which contains Thunderblight Shards for use in the Cornerstone Forge. New buildings, orders, perks, and legendary Cornerstones are also present, alongside 28 new soundtrack tracks. Frogs become available at player level 9, and the new biomes appear on the world map after the current cycle concludes.
