Hairless Adviser! The Neath's most adorable nation needs your wisdom once again!

Guide the feuding rats and cavies of Pigmote Isle to independence. Sabotage their ambitions for your own benefit. Help them flourish, or pick through the ruins of their doomed dream. London will never believe a b____dy word of it anyway.

This free story continues your adventures on Pigmote!

The Pirate Poet and the Merciless Modiste

The Pirate Poet and Merciless Modiste are now ready for you to meet!

The Pirate Poet is an exclusive character for Kickstarter backers at the Corsair level and higher, though all brave Captains can recruit the Modiste if they dare. We’ll be in touch via Kickstarter if you’re due to encounter the Pirate Poet! UPDATE to the UPDATE: Backers! The Pirate Poet code is now working. Enjoy!

This backer-exclusive content will be made available for purchase, further down the line.

Modding Constants

You can now include the 'Constants' folder as part of your mod, allowing you to adjust properties like ship speed and engine power.

Startup and connection issues: FIXED!

Sorry, all - we know that as of yesterday, a lot of new purchasers are seeing issues with a grey screen on startup. As of today, everyone is now seeing a 'Can't Connect' message for the Get New Stories button - which is a bigger problem, because Get New Stories was a workaround for the first issue.

We put out a patch yesterday, and also did some server migration work yesterday / today - this has caused two separate issues which are colliding in a nasty way.

We are working to fix this right now. Really sorry for the trouble. We're happy for you to request refunds from Steam in the meantime (even if you repurchase the game later).

About This Game


Take the helm of your steamship and set sail for the unknown! Sunless Sea is a game of discovery, loneliness and frequent death, set in the award-winning Victorian Gothic universe of Fallen London.

If the giant crabs, sentient icebergs and swarms of bats don’t get you, madness and cannibalism certainly will. But that old black ocean beckons, and there’s loot for the brave souls who dare to sail her.

Betray your crew, sell your soul to a Devil, marry your sweetheart. Survive long enough and you’ll achieve your life’s ambition.

You will die, but your legacy will live on…

Key features

  • A deep, compelling world packed with 200,000+ words of stories and secrets. Find your father’s bones. Determine London’s destiny. Defy the gods of the deep sea.
  • Beautiful, hand drawn art - castles of sparkling ice, prisons perched on lily pads, fog-shrouded lighthouses and the DAWN MACHINE.
  • Your captain will die. But you can pass on resources from one generation to the next. Acquire a family home and a hoard of heirlooms. Build up your own story across generations of zailors who braved the sea and lost - or won...
  • Real-time combat against ships and Zee-beasts, spider-crewed dreadnoughts and sentient icebergs.
  • Light and dark, terror and madness: stray too far from the gas-lamps of civilisation and your crew will grow fearful and eventually lose their sanity.
  • Upgrade your steamship with powerful engines, cannons and pneumatic torpedo guns. (Or buy a bigger, better ship.)
  • Hire unique officers like the Haunted Doctor and the Irrepressible Cannoneer. Each has a story to tell, if you can draw it out of them.
  • Choose a ship’s mascot: the Comatose Ferret, the Wretched Mog, the Elegiac Cockatoo, and more!
  • Trade or smuggle silk and souls, mushroom wine and hallucinogenic honey.

Here's an example why this game is awesome:

At the port I picked up a passenger.
Turns out he's a shapeshifting face-eating monster.
One by one he eats my crew and drops faceless bodies into the sea.
Several times I tried to catch him and failed.
At the end only me and my first mate are left alive.
There's a bunch of options how to deal with him like fight, talk, use this, use that...
There is also an option to admit that there is no monster and its been you all along.

How much greater can it get?

I want to like this, I really do. But the game's economics are so punishing, and the sheer amount of grinding, is so high, that I can't enjoy the wonderful world the writers have created. To have a chance to survive, you have to play boringly; if you seek out adventures, you'll die quickly. Even simply trying to make money, you stand an excellent chance of dying. And then it's a long slog back.

There is this fashion for extremely punishing games. But it really takes the fun out of it for me.

I want to recommended this game. I want to, but I can't.

Sunless Sea is a very original and interesting game with a unique setting. In it, you choose who you are from a select few backgrounds and victory conditions, then you embark into the titular sea to explore and achieve whatever goal you set for yourself. Think FTL, but instead of jumping from event to event you actually steer your ship there and can sail around the map at your leisure.

All of this sounds good one paper, until you have to start managing your resources most of which cost money. the early game will see experienced players shooting back and forth between the main hub (London) and various select locations that can be farmed for money. Money will get you new ships and improvements like any other game, but the problem comes when this money farming grind starts to spill over into the mid game and even the end game. next thing you know ten hours have gone by and your still running sunlit mirror boxes back and forth for cash because your nice new ship consumes more fuel and supply. Only on occasion do you find the time to explore other parts of the map or continue a story line for one of your officers.

And then, when on your 20th journey to the money farm, you die. Why? No idea, because after 20 times you stop actually reading the text for the event.

Sunless Sea is a game I want to recommend, but the grind is pushing past the level of most japanese games. What I can say is that it's a game that needs a sequel, because there's a lot of great stuff going for it, and even more stuff that needs improvement.

We'd been at zee for a long time, running dark to conserve fuel and avoid the attention of the pirates and great beasts. Despite my best efforts -- spinning tales of comfort for my zailors, brazenly defying Nightmares, even initiating an affair with my engineer -- I'd managed to let my Terror get all the way to 100%. The achievement pops up; "Lose Your Mind". This doesn't bode well, but I'm a mere ship's length away from home port, and docking will reduce terror to 50%; a much more manageable level. Surely I can hold out just a little--

I'm instantly presented with a choice between murdering my entire crew (with 12% chance of success), or attempting to win them over (9%). Failing either one, I was told, would end my game. I did the only thing I could do, and somehow managed to kill everyone aboard, save two. We made harbor and, with a fresh batch of new faces, set out to zee once more.

Time passes.

An adventurer whom we've been running jobs for finally announces that he has all of the supplies he needs to make his final journey and I, having proven my capability, am his first choice of transport. There's just one problem...my trusty ship lacks the capacity to hold his cargo with room for food and fuel. We're going to need a bigger boat.

I buy a bigger boat and hire on twice again as many zailors as I already have. We load up and set sail, but not before I accept just one more smuggling job from my "friend" with the bad eye and the concealed knife. Corsair's Forest? I've been there a dozen times; consider it done.

It's not until we're two days out that I realize my new ship has half the speed of my old one, and my triple-size crew are a hungry bunch. We're running low on supplies before we've even reached our initial destination, but we make the drop and start to head home.

Then the realization strikes. If we dock in London now, before finishing that smuggling job, I'll have to cough up the fee plus a hefty chunk of interest, not to mention lose a valuable connection...but the nearest trading port is in the opposite direction.

It took every scrap of food we had, but we managed to reach Mount Palmerston without resorting to cannibalism...again. We traded with the devils for supplies and loaded up on coke freshly dug from Hell. On our way home we made port at Pigmote isle, where a civilization of guinea pigs threw a banquet in our honor -- their returning saviors, though this time we were the ones in need of saving.

After a harrowing encounter with a manic Jillyfleur brought hull integrity to 1%, and a misbehaving Clay Man took five lives before we subdued him, we were desperate for rest and repair. An ill-fortuned shore leave on Gaidur's Mourn pushed Terror to worrying levels, but we had our package. As we pulled out of the port, a straggling pirate ship fired one last shot across our bow -- but the shell missed by an arm's length and we were homeward bound. Two days later, limping into port with a skeleton crew, I breathed a sigh of relief that I'd narrowly escaped losing my mind for the second time in the space of a week. My sweetheart and child welcome me home. I say nothing of the suicides -- surely they were suicides? -- that only I had been privy to. I pass on an uncanny artifact to my son; someday he, too, will be a zee captain, with enough cares of his own. No need to trouble him with details.

My friend has another job for me, and the Admiralty has need of news from the outlying colonies. I take a loss on a purchase of a smaller ship, name her after the one I'd traded to begin with. Eighth of my house and 211 days at zee, I sail on.
