This expansion introduces six new investigators, each featuring distinct abilities, decks, and playstyles to enhance your battle against Cthulhu. It includes Specialist Cards, a new card type designed for investigators with specific traits, offering deeper deck-building strategy. The gameplay encourages cooperative decision-making with fresh mechanics that challenge players to adapt. Compatible with The Drowned City Campaign Expansion, it extends the Arkham Horror narrative, allowing players to explore the alien city of R’lyeh. Note that the Arkham Horror: The Card Game core set is required, as this expansion provides additional player cards, investigators, and deck-building options.
