Description
The steamship SS Atlantica is bound for Boston in 1913, but something beneath the waves has followed it into the Atlantic. In Unfathomable, players work together to keep the ship afloat, fend off Deep Ones and manage dwindling resources—while hidden traitors quietly undermine the voyage from within.
Every player has a secret loyalty. Human passengers must cooperate to survive, while hybrids and cultists create crises, sabotage the ship and wait for the right moment to reveal themselves. Character abilities, tense choices and uncertain loyalties make every voyage play differently.
