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.

Didn't really like it. This is the first time a rougelike game wasn't enjoyable to me. The story, art, and ambiance are amazing. The game play is slow, tedious and boring. The first time you discover something its pretty neat but discoveries and random events seem few and far between. Combat is pretty bad and there are long gaps when you are doing nothing.

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

Do your first playthrough without Googling things. You may not live long, but it will be one hell of an experience.

Seas offers an interesting world with decent exploration but fails to offer sufficient trading opportunites or even vaguely rewarding combat. Seas really does appear to be half complete, offering little more than good writing and narrow, repetitive, shallow gameplay.

Ideally, Seas should have trimmed the thoughtless busywork leading to such tedium and offered a quicker, slimmer experience. Instead we have a game that is glacially slow and unrewarding, and generally only enjoyed by those following guides and walkthroughs, with saves enabled.

The story, art, and ambiance are amazing. The game play is slow, tedious and boring. The first time you discover something its pretty neat but discoveries and random events seem few and far between. Combat is pretty bad and there are long gaps when you are doing nothing. I realised I was iin for something thats not going to be my liking after my third captain when I was reading everything and knowticed it was all the exact same from the last two times. I think the biggest mistake I made was honistly tring to have fun on my first two captains and exploring without ever actally stocking up on fuel and stuff before I started really playing. When I say down and really started trying to play I felt like I had seen most everything from just exploring so all that was left as reading all the stroy and text. All the story and text of witch would always be the same every time I started the game.

I'll recommend the game, with one caveat. I wouldn't buy Zubmariner until they implement an easier path to access that content. The first time I did the missions to unlock my Zubmarine, it was enjoyable. I liked the fact that for one save I only had to do it once. Then my save file got corrupted and I needed to start a new game. It's a pain in the rear to unlock the zubmarine, especially after you've done it. Just now, I did all the required steps and was headed back to the port, when I was attacked and couldn't esacpe, meaning I have to start the entire process all over again.

I get it, it makes sense in the setting that it would be difficult to access a zubmarine, however, I feel that it is too tedious at this time, and unfun to do more than once.

This game just didn't gel with me. However I felt that it wasn't for me, rather than it wasn't good. My main issue was the game loop of travelling around picking up the same / similar stories got dull, and this stopped me getting past the early game, and I can't judge how it played beyond that. Definitely worth checking out, but do some research to see if it will be a game for you

As punishing as it is boring.

The start of the game is just ♥♥♥♥ing brutal. Your first task is to figure out a postive income stream because your ship is utterly beholden to everything with a bouyant profile. So you find some ♥♥♥♥ing mind numbing task which brings in cash and of course after 4 or 5 trips the game decides yeah, ♥♥♥♥ this guy, let's change up the once reliable narrative and complicate his pitiful exsistance even more. No more cash flow. And all the while you're parading back and forth, at the rate of a dog which has had it's legs cut off, you're getting ♥♥♥♥ed, front to back, with very little romance by the various "food fuel and terror" mechanics with which you have to make a Faustian bargain just to last another 5 god awful ♥♥♥♥ing minutes in this relentless and somehow boring hellscape. You wanna run without your ship lights to save fuel? ♥♥♥♥ you, terror is off the charts and now you're having a mental breakdown everytime you close your eyes. Enjoy paying off the interest on that decision, you ♥♥♥♥.

If you wanna play this game, have at it, I definitely reccomend shoving shards of glass down your urethera in order to relax in between sessions.

I loved sunless sea when i first got it. it had a challenge and i respected that. it had expensive ships and upgrades to look foward to getting. that being said, it didnt take long for me to realize that i was never going to afford the big fancy ships or the retirement mansion. nope. this game is hard, and unfortunately, i found myself making the same routes, in the same slow ship, just to make ends meet. nothing was getting done. i started disregarding all the special sidequests and witty dialogue eventually because "no, does it look like i have that special item on hand? i sold it already. just give me the port report and give me some goods to sell at london so i can afford some damn fuel". eventually, i came across the sunlight smuggling method and became invested on a whole new level. Oh Em Gee, im getting crazy money from this! i can finally afford a big fancy boat and the mansion, and with all the money problems out of the way, i can just focus on how great this game is and do all the sidequests! nope, i was wrong, because the devs nerfed it and i literally DIED from having sunlight on my ship. now, im upset, like CLEARLY upset. i thought there might have been an easy route, you know? wrong. i dont need this in my life. i just want to be happy, and this game doesnt make me happy. thanks anyway, though.

This is not a "deep RPG" or anything like it. It is a merchant game with some roguelike aspects, and very wierd quasi-victorian, vaguely lovecraftian, writing.
I had fun until i realized that my boat was never going to go all that much faster, and that the boredom of moving over the same paths, at that same slow speed, was going to drive me crazy.

There was true potential for greatness here, but despite initial impressions of excellent worldbuilding and difficulty, once you explore a bit further the game reveals itself to be a deal more shallow than it initially seems.

Most items that seem special and rare can actually be acquired easily and cheaply with the addition of new trading possibilities that come once you've spent a bit of time in the game, along with inexplicably cheap sources of items found in the expansion such as drowning pearls from a new port called Dahut.

This review would still have been a thumbs up, but as is often the case with good indie companies, the majority of their fanbase will never really criticise much of what they do, so it's left to the rest of us to try and push for improvement in areas that feel weak or problematic.

The game is worth your money, but is sadly quite flawed in some respects. I'm not sure whether this was done in an effort to broaden appeal, or was simply the decision of a dev at Failbetter who did not understand the world his colleagues have crafted.

I will probably be beaten to a pulp by the positive reviewers,

But what you are looking at here is pretty much Fallen London but with an extra top down 2d map where you pilot a very slow vessel tediously across a map of the Underground Sea.

The world itself is original but the gameplay elements that are the innovation I find tedious, and experience a lack of control for even basic needs like getting enough fuel and food.

For example:

Because of the rogue-like nature of the story, I can't simply just buy items in one port, ship them to another and then sell them.

Instead you get port reports, which you may or may not be able to use to trade for food or fuel (because there is still an element of luck).

Travelling from one location to another can take upto 30 minutes, in that time you have random encounters with sea-creatures and so forth. This would be okay, but I found the combat irritating as you need to stop and start your steamer and then hit them with the gun. The gun seems to be based on a skill roll so sometimes it will miss.

You get stuck in situations where you have 1-2 supplies and no way of getting more, what Captain would knowingly set out with starvation hours away?

The world
The narrative

Everything that makes it a "game"
