Risen 2 - Dark Waters

Set several years after the events of the first Risen, raging Titans have devastated the world and pushed humanity to the brink of extinction. Monstrous creatures have risen from the watery depths and their attacks have brought all seafaring to a halt. The town of Caldera and the Fortress of Crystal — the last haven of the Inquisition and the Old Empire — survive only because two Titans have begun fighting each other. The hero, now a member of the Inquisition, is sent on a quest through a pirate-themed, Caribbean-style fantasy world to find a legendary treasure and discover a way to destroy the Titans, while pirates and a sea monster known as the Kraken disrupt every supply line.
