Opis w języku angielskim: From unfathomable depths, an ancient power stirs. The dark abyss, home to forgotten creatures, opens wide, releasing a threat that rises with the tide. The waves carry a chilling omen of destruction. Only those brave enough to face the unknown can push back the darkness and save the harbor from impending ruin. One Card Dungeon: Harbour Clash is a standalone adventure that follows the same setup and rules as the base game and the M’Guf-yn Returns expansion, with new features: a new Dungeon card, a new class, and the new Item module! —description from the publisher
