From publisher blurb:
Sunken is an RPG of nautical horror based on the Trophy system. The stories we tell are often not of gallant survivors but of the hard-pressed, star-crossed crestfallen. They are the poetry of the broken and the inhuman breakers: haunting things, deep and dark and bellowing things, unfathomable things that consume all that edges to their precipice.Sunken is a tabletop roleplaying game about these things. It is a tabletop roleplaying game about these things and the sea. It is a tabletop roleplaying game about how your characters find their doom among these things while at sea. Sunken shifts the focus of the world of Trophy onto – and below – the vast and treacherous Salt Sea, expanding "That Silent Howl" from Codex: Void into a full stand alone system that remains rooted in the mechanics of Trophy Dark.
