Dive into the world of Sunless Sea

Sunless Sea is an atmospheric exploration RPG with roguelike elements from Failbetter Games, the studio behind Fallen London. Set in a haunting Gothic universe, it sends you across a vast underground ocean known as the Unterzee, where every voyage is shadowed by danger and discovery.

Take command on the dark waters of the Unterzee

You captain a Victorian-era steamship and set out to chart the mysterious sea. Manage your fuel, supplies, and the sanity of your crew as you sail between strange ports. Linger too long in the dark and far worse than giant crabs may rise to meet you.

Recruit and trust your officers

Sign on a crew of distinctive officers, each with their own background, ambitions, and secrets. Earn their trust and they'll open up over time, revealing personal stories and quests that shape the course of your journey.

Darkness, fear, and madness

How long can you stay away from the light of port? Prolonged time in the abyss erodes morale and pushes your crew toward terror and madness. Be ready for hard choices that can change your fate forever.

A world full of mysteries and stories

With over 350,000 words of intricate writing, Sunless Sea offers countless tales and puzzles. Hunt for your father's bones, decide the fate of London, or dare to challenge the gods of the deep.

Build a legacy

Your captain is mortal, and death is rarely the end. Pass your wealth, ship, and hard-won traditions down to the next captain, and forge your own legend across the sunless sea.
