Unfathomable - From the Abyss

Unfathomable: From the Abyss is an expansion that pushes the hidden-traitor voyage into darker waters with fresh threats, tools, and twists.

You’ll fold new options into every journey—expect additional characters to crew the steamship, more monsters from the deep to stalk the hull, and modular cards and scenarios that ratchet up suspicion and tension. The new content slots cleanly into setup, giving loyal humans and treacherous hybrids fresh ways to bluff, scheme, and survive as the ship battles the unknown. Requires the Unfathomable core game to play. Available now at Boarding School Games—gear up and play.
