Unfathomable

Unfathomable is a hidden-traitor game of suspicion, survival, and cosmic horror aboard the steamship SS Atlantica.

Three to six players work to keep the ship moving toward Boston while Deep Ones attack from the sea—but some players may secretly be hybrids sabotaging the voyage from within.
