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

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.

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

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.

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.

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. Here is the link to research that my comments are based on: http://gaming.stackexchange.com/questions/174752/whats-the-most-efficient-way-to-travel-with-your-lamp-lit

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.

An interesting blend of exploration, puzzle solving and role playing in a top-down perspective. The location has a steampunk meets Discworld vibe that is oddly engaging. If you're looking for something a bit different, this is the game.

Its hard to write a coherent review of this game. The writing and the music are stand out hits, and I have literally dreamt of using the game engines from SubNautica or Dishonoured to build the locales in AAA space. Ive had discussions in bars with gamers and writers about the genius and the horror of Red Honey, about how difficult it is to write Cthulian-type horror without sounding hackneyed.

This really is an incredible game. Zubmariner added a lot to it. I know Ive racked up les than 40 hours, but those have been 2 hours followed by "I need to stop playing and get into this over a weekend" or getting close to completing one of the sub-storylines and something going horribly wrong and ragequitting for a week or two.

Cant recommend it enough.
