Take the helm of your zubmarine and set sail for the unknown! Zubmariner is the first expansion to Sunless Sea: deeper, darker, and more marvellous than anything you’ve seen before.

All the powers of the Neath agree: there is Nothing of Consequence beneath the Zee. They are lying. You've heard there are fortunes to be made by those brave enough - or hungry enough - to dare the deeps.

Disturb the aberrant societies that flourish in the dark. Defy wreckers. Seduce a Drownie. Embrace or condemn the distinctly un-British customs of these cold, fathomless places.

You will definitely die. Will your next captain dive?

If you bought Sunless Sea in Early Access, you'll find Zubmariner has been automatically added to your game. Thank you for supporting us when we hadn't found our zee-legs.

Key features

  • More of the deep, compelling world of Sunless Sea and Fallen London, packed with stories and secrets. Dive into unplumbed abysses and claim their eerie blessings.

  • More beautiful, hand drawn art. Let your curiosity take you to what lies beneath the Sea of Statues, Mount Palmerston, and the dread Dawn Machine.

  • Convert your ship into a Zubmarine and dive anywhere in open water to discover new cities, zee-beasts and environments to terrify your crew and slake your hungers.

  • 11 new underzee ports, each with their own tales and opportunities for the enterprising Trespasser. Visit Dahut, the city of drowned delights. Brave Wrack, where a Fair King rules the unforgivable. Explore Anthe, and sharpen your tongue, your liver, and your spleen.

  • Seek immortality in a new ambition! Track down the Seven Against Nidah, who once came within reach of eternal life. Can you succeed where they failed?

  • New enemies to face, from the cunning Wreckship to the inexorable Constant Companion.

  • Discover the treasures the zee has claimed. Explore ancient wrecks, avoid hostile witherweed, discover the unexploded Unclear Bomb.

  • Sanity is scarcer. Death is closer. We warned you, Trespasser. You should not have come.

Zubmariner launches in 6 hours! | NEW, FREE content in Sunless Sea

We’re beginning the launch day celebrations for Zubmariner with a delicious piece of news for all owners of Sunless Sea: we’ve given you some chunky new quests in the base game! You don’t need to buy Zubmariner to enjoy them (though some will give you a little taste of what’s in store, down below).

New faces in London
Each time you create a captain, you’ll meet a passenger who wants to recruit you in London, and begin a unique quest. There are a total of four new passengers to meet, and all of these quests contain foreshadowing regarding Zubmariner.

Your old friend, the Blind Bruiser
When the Blind Bruiser asks you to carry cargo, you can now ask if there’s another task he’d like you to do instead. There are two different, new quests to discover, both to do with the Cheery Man…

Mutton Island: Apocalypses
After you’ve made a few trips to London, strange events will start happening on Mutton Island.

Rose Market, Revamped
Opportunities at the Rose Market are no longer randomly determined every time you visit London. Instead, they’ll stick around until you fulfill one, or until you ask for them to change. This means that Rose Market requests acts as mini-quests, and you can set zail knowing what items will fetch a good price.

What bounty! If all this whets your appetite for Zubmariner, you don’t have long to wait. Release is at 6pm BST / 10am PDT today.

“Sunless Sea's method of storytelling isn't unique, but it has never been realised with such impact and elegance.”
10/10 – Eurogamer

“Absolutely the best writing in any video game since, well, as long as I can remember.”
10/10 – PCGamesN

“a very compelling and satisfying adventure... The realm of possibilities seems endless, and every time I set sail I find something new.”
9/10 – Destructoid

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 350,000+ 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.

Sunless Sea came out of the blue last year and dominated my gaming time for months. 300+ hours and a dozen or so captains later, I've finished the game in every way possible, done every sidequest, went down every story branch I could find, fought off not one but two mutinies, and escorted hundreds of hapless zailors to hundreds of gristly deaths. The world is dark and wonderful. The writing is, without hyperbole, some of the best I've ever seen in games. Never in a hundred years would I have thought that a game consisting almost exclusively of fetch quests could be this engrossing.

I really like the grim worldbuilding in this. It extends the fun and memorable world of Failbetter Games' browser game Fallen London, and that's what brought me here in the first place.

That said, I really wish this was turn-based. This game's setting is lethal no matter what, but it's a lot more lethal if realtime combat isn't your thing. And with that lethality in mind, I think the game's opening would benefit from some streamlining so that you can set sail again more quickly after a captain dies. As is, there's a lot of fixed, routine stuff to click on before you get going again, and that loses its novelty after your second run. A one-click randomized character generator would help, but even after character creation, there are a few repetitive tasks to complete before departing.

i understand its a sailing expedition story, so its meant to be a bit aimless
but i feel if goes a tad too far, dont need a hand holder, but some vague directives would help

also you better have your p&p handy, and fully read everything, cause there are no reminders in game
if you forget what or where you needed to do/be your outa luck
even though its clearly a reader oriented game, normally you wouldnt expect it to
be "read every word or you wont have any clue about anything, ever"

actually you might want to add into your notes aswell (fuel cost to port, heck draw the map really)

if your up for a tedious, slow grinder, and like reading (as in actual books not just lore pages as found in some games)
then yes, this game is nicely written, drawn, and the controls are relatively smooth (spinning about for combat sux)

im all for investing many hours into a game (like final fantasy style titles)
but expect this one to be very slow paced (artificialy)
and be comprised mostly of desperatly hoping port to port for fuel and supplies

theres more than enough content (and reading) to be had to rack up the hours
there is no reason to falsely slow the game down with fuel consumption, speed restrictions
and over priced upgrades (and some invincible monsters but that might be a bug)

if your expecting a CYOA story about sailing, then you should look elsewhere

my reasons for quitting are
lack of direction,
artificially made extra slow and grindy via high upgrade price to earnings ratio
nesesscity of note taking (quest log is barely existant and has no relevent details)

no freedom of exploration, you MUST hop port to port or youll run outa fuel, and if your going to do that
you might as well try to do the quests you pickup, which usually are half the map away
which is why you better take notes, cause by the time you get to a destination
you wont know why or what your even there for

great game imo, but poorly thought out execution
(some direct target audience probably opted out or gave up)

not recomended cause its a small niche of gamers who will be able to fully and whole heartedly enjoy
what otherwise would be nearly a masterpiece

Day 153
The crew feels we have been away from London for too long. I am starting to feel the same. Harry says our food stocks are running low. Johnson says the same for our fuel. Gilbert says we will get an extra two days of travel if we turn off the lights, but this far away from land, it would cause serious concerns. Eric is keeping the engine well-maintained, at least, and Patricia says our stock of rum will keep the crew happy for now. Sly, Moist, Carrot and Tom are growing nervous, however, looking out over the gunwales, eyes following invisible beings out of sight. Will continue looking for land, and take advantage of the nearest port.
As captain, it is my responsibility to get all 10 of us home.

Day 155
Tom spotted lights on the horizon, a shoreline! We are heading for them with all haste. If it is a habitable port, we will stock up and put aside time for shore leave.

Day 156
It was a port, but no town nearby. We still took advantage of shore leave to relax and stock up on food, finding much fruit. We had to throw away the berries though, as upon tasting them, Sly turned purple and fell to the ground in spasms. Patricia kept us from losing him, but only just barely. He is recovering in his bunk now. This still does not solve our problem of fuel, but a note near the port hints at a dock due west by southwest.

Day 157
Our Zubat spotted the dock. Abandoned, no people, or animals, or anything in sight. Still, there were drums out by the dock, some half full. Enough for three days' travel. Sly has recovered enough to work again, much to the improved morale of the crew. We will continue due south.

Day 163
First sighting of land in days. Heading east.

Day 164
I will recommend avoiding this land in the future. Sly led Tom and Moist ashore searching for supplies and trade goods. Only Moist returned. While he carried some artifacts that will be useful for trade in London, he was covered in scratches and bites, raving about rats. Some rats. The only other words he said were "Down to the bone" again and again.

Day 167
Better luck. We landed in a port. Ashore we learned that the artifacts were greatly valued by locals on a nearby island. The people in port gladly traded us the artifacts for enough food and rum to get us home. No fuel though....

Day 168
Out of port. Out of sight of land. Out of fuel. Out of that food the ♥♥♥♥♥♥♥s gave us. Or might as well be. We opened the crates to find nothing but pickled mushrooms. At least the rum is good, though.

Day 170
The crew is getting desperate. How desperate? We are considering eating the pickled mushrooms. Patricia has advised against it, but with no food, we can't get any other provisions. For Sly, Carrot, and Johnson though, any food is good enough.
That said, me too.

Day ???
My shoes are too big for my hands. The fish colonize the north tobacco inlands. Pretty colors are dancing in the sky. Language fails to convey meaning. I count my fingers to stay sane. I stopped at 1250.

Day 178?
Patricia tells me the mushrooms have worn off. I was the last one to recover. Not surprising considering how hungry I was. I ask Patricia how the crew faired this storm, but she only continued with her downcast eyes. Harry, Gilbert, Johnson, everyone was silent about how they maintained sanity and staved off hunger during the long nights. Carrot and Eric weren't so much silent as unavailable for comment. A small ceremony was held.

Day 187
My right hand still looks bigger than my left, but things are progressing normally. Or rather, not progressing normally.
I have come to terms with how we survived my week under the influence of the mushrooms. We have since banned all fungi from the menu. Plenty of meat lately, though. Blue tells me there is nothing to worry about. Patricia too.

Day 190
We decided to try some fishing. Just took some of the meat left over that was causing a stink, and dropped it on lines into the zee. We dragged up a great blind eel, hoping for a whale to get more fuel from. The meat is too poisonous to eat, so one problem will remain unsolved. The crew is trying to render the fat from the meat into a usable fuel now.

Day 191
Patricia says that we are ready to test now. A quick prayer to Salt, and the hope for the blessings of Eric. The fuel is a mixture of eel fat and rum. Hopefully this time tomorrow, our food and fuel problems will both be solved.

Day 192
The fire was tremendous. On second thought from what Eric had told me in the past, the engine relies on a very specific mixture of fuel that when off can lead to massive explosions, or massive fires. Luckily, we only lost Carrot when the engine room caught fire.
Tonight's meat ration was sweeter than I expected.

Day 197
Pirates! Glorious Pirates! We sat in the water until they though our ship completely empty, then overpowered them as they boarded. We lost Patricia... Poor Patricia.
Rather, poor us. With one woman on board before, we all had a chance for relief. Now, our best hope is... something no one will discuss.
For now though, food and fuel!

Day 206
East was not the right direction. We are turning around.

Day 217
The eye! An evil eye follows me every night! I can't sleep with it watching me!

Day 220
The eye is gone! I saw it in my dreams. Suddenly, my mouth opened as if my head were on a hinge, snapping shut over the eye. And then, the dreams disappeared.
Gilbert turns away everytime I walk on deck now, but Blue and Fluffy say not to worry. Harry cooked another great dish tonight.

Day 222
Times are desperate. Harry and I carved oars so we would get some movement through the zee. Gilbert remains silent. Sly puts in his time aloft now, only. Blue, Fluffy and Rascal say not to worry.

Day 240
We are moving slowly to home. No engine, no food. Just our arms, and our hope for rescue or salvation. We checked on Sly today, Yeltzen and I. He was still in his seat aloft, but not moving, not breathing. Gilbert dislikes Harry's cooking now.

Day 256
We can just barely make out the lights of home now. If we push though the night, we just might make it. I tell Blue, Fluffy, Rascal and Yeltzen to stay below decks to work on the engine. Meanwhile, Gilbert, Harry and I row like the devil's on our tail.

Day 257
Damned rats! No closer to home, and they take Gilbert from us too! Well, we still have Gilbert with us. Just not living.
I guess he will live in me, Harry, Fluffy, Blue, Rascal, Yeltzen and Ivan now.

Day 264
A lucky break! Charging down on us, a crab met the quick wits, and much quicker guns of me and Fluffy. Harry and Blue dragged it aboard and cooked it up. A great feast was enjoyed, with much smoked for later. Unsure how long it will last, though, with three weeks' travel at least by oar between us and London. At least we still have some mushroom left, Yeltzen reminds me.

Day 279
Harry tells me that the crab is gone. We are halfway to home, running on muscle power, and out of fuel. Food too. Same thing. Blue is getting anxious. He and Yeltzen, Fluffy and Ivan, and Rascal too. They tell me we must go on, but we need food most. Cathy reminds me of the mushrooms. I mention this to Harry, and he agrees that as long as half the crew refrains from eating them at a time, they should be able to control the other half. It is our only chance.

Day 432
After several months in hospital, the doctors tell me I can return. To the zee, no, but to my family, yes. I dare not tell my boy what happened to Uncle Harry and Carrot, nor anyone else. It will all be a secret between me and Ivan.

What will your story be?

This game is quite different from the trailer, but it is still a great experience. The world and lore is phenomenal, but extremely unforgiving. It takes a vast amount of time and restarts to be able to survive long enough to do anything. Stray monsters or ships will destroy you in the blink of an eye by sheer chance but its far more likely youll run out of necessities. The main focus of this game is to keep your ship afloat long enough to explore. you will have to manage money, fuel, and supplies in a world where they are difficult to aquire. you cant just grind for money, you mostly get it by completing the story so you have to take risky judgements and hope there isnt a dreadnought ship on your way to the next dock. 25 hours in and i was far from ending anything by the time i got tired. BE AWARE that the first 20 hours of that was merely figurig out the subtleties on the story so my next captains could survive and do it right, i kept a notebook of what each dock sells at what price. i strongly recommend recording info because you will definately be doing what you just did several more times hours later.

This game is incredeibly buggy on mac. I am using a new Retina iMac so hardware is not the issues.
Never the less the game constantly drops frames even at a lower resoloution. Worse still the game will not save my resoloution changes and continues to play with a ton of lag. When ever you go into combat the missles or whatever will never strike the creatures and you will invariably die to a swarm of bats or a mollusk. Needlerss to say i have better things to do with my time than waste it on this tripe.

I would highly recomend saving your money and giving it to a reputable vendor. I feel completely ripped off and would never buy or support one of FAILBETTER games (least they got thier name right) ALso if your looking for more opinions check out thier game Fallen London on the app store you will see it has a 1-2 star average and does not work at all.

Avoid at all costs.

I really like Sunless Sea, however my recommendation comes with an asterisk. I do not think this game is for everyone. The most traditional game part would probably be the naval combat and that mostly takes a backseat to the rest of the game. The main focus of the game is the stories, the narrative of the Unterzee; Sunless sea is heavy on text content.

The game is rogue-lite, islands in the zee move around between playthroughs (or "Captains") and you can leave some of your progress to your next Captain upon your death or retirement. The islands and ports function like a "Choose your own Adventure" where you can follow different storylets to help out some devils or talk to people who only speak in questions or perhaps sell your soul to some monkeys. All of this is set in some alternate universe victorian era fantasy Earth where London was taken a mile below the earth by some bats and space pterodactyls.

If you're unsure about this game try Fallen London, it's a browser game with the same style and athmosphere that focuses on Fallen London itself rather than the vast Unterzee beside it.

Nice writing but the game machanics are broken up to a point that I regret engaging in this game. Here is why:

If you die(and is a struggle not to), you are supposed to remember all the chocices because you wont read all stories again, right? So after I first died after a longer playthrough I was not sure If I wanted to give it a second chance.

Lots of mechanics are not logical* (look at the bottom for justification) or player is not informed about the outcome of major decisions which frequentily is fatal for the run that is usually quite long (10, 20 or 30 hours).

You really need to be playing with wiki if you want to have chances to get further and I don't think this is desirable.

Also the oxford-english is damaging the experience greatly for people who are not A-level speakers.

Althought the first two or three playthroughts were fun(10 hours), later attempts to beating the game brought strong frustration. (Yes I had fun for many hours, but i disregard that if I cant have satisfaction from finishing the game!)
Writing is great but the game design is substantialy flawed. The text novel mixed with a rouge-like game is a misconception for me.

Designers should think twice before releasing a thing that is engaging but not rewarding. This is acutally harming the people playing the game.

*Example: Fuel consumption does not depend on the ship speed but on type of the engine. AND better engine makes you actually less efficient (money/distance) altough a little bit (imo way too small bit) faster.

Fantastic game. Reminds me of fantastic board games like Eldritch and Arkham Horror, with a more action-oriented thing at its core. Probably my favorite exploration AND survival game out there right now.
