Zubmariner launch trailer | Our next game revealed!

Firstly, you'll want to see Zubmariner's launch trailer

Now, if you caught our live panel from EGX, you will have heard the exciting news:

Our next game, the sequel to Sunless Sea, will be called Sunless Skies, and we’re doing a Kickstarter for it in February next year!

There’s very little we can say at this early stage, but to whet your appetites:

7 Facts about Sunless Skies

  • As with Sunless Sea, it’ll be rich with stories. The Victorian Empire in space – the High Wilderness – a “blistering, wonderful night” among the thrones and domains of the stars. The Empress has abandoned London and led an exodus to the High Wilderness, to carve out a new British Empire. With the Empire being increasingly authoritarian, bohemians, revolutionaries and outcasts – like you – are trying to make a life for themselves on its fringes.
  • It will elaborate on Sunless Sea. We’re enhancing the stuff we liked, and refining the experience. It will be a punishing game, but respectful of your time.
  • At full release, it will be available on the same platforms which Sunless Sea is available on now: Windows, Mac and Linux.
  • We will use Early Access again, taking on board all of the lessons we learned from Sunless Sea.
  • Why the name? The stars are dying. The stars are the Judgements: the inventors, arbiters and enforcers of the universe’s laws – but a revolution has begun, and the stars are being murdered.
  • Our influences include: the science fiction of H G Wells and C S Lewis, the planetary romances of Leigh Brackett, Art Nouveau, Event Horizon, trains.
  • We are running a Kickstarter for it in February! Stop the clocks, mark your diaries, save your pennies!
At the moment we are in pre-production: art concepts, topline story, weekly seminars looking at different aspects of Sunless Sea that we want to renew or update.

Hopefully you're as excited about it as we are!

Zubmariner comes out in 18 days! | Sunless Sea text and UI resizing now available

It’s only 18 days until Zubmariner comes out! That’s not long at all.

Between now and then we’ll be releasing the zee-plumbing, heart-pounding launch trailer, and discussing Zubmariner live from EGX. You can watch live on their twitch stream at 4pm BST on Saturday 24th September: www.twitch.tv/egx

(We’ll also be announcing our next game! We’re slightly beside ourselves even thinking about that!)

UI and Text Resizing

Sunless Sea was made in Unity 4, which had some limitations particularly around the way it handled text. As a pretty text-heavy game, we ended up with many players finding the game unplayable due to their screen resolution. Text was tiny or fuzzy. Not ideal!

Happily, in Unity 5 we’ve been able to do a lot more with the user interface, and have fixed the fuzzy/tiny text problems (with the help of everyone who opted into the Unity 5 beta - thanks!). Please enjoy fiddling with the size of your text and the gazetteer to your heart’s content.

“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.

Wait to play this game until you have quiet time where you can turn your headphones up and ignore life around you and you will feel the full effect of The Sunless Sea.

Is there a sea more sunless? This game is marketed as an immersive, story-driven, almost roguelike, nautically themed romp through alternate history London, circa 1890s. The people at Failbetter Games have created something both motivating and meaningful in their games surrounding Fallen London, utilizing hundreds of storylets that drive the player toward various choices and options.

At first playthrough, especially if you didn't play the precursor game Fallen London, you will find yourself immersed in a world that follows many of the rules and expectations of our own, but with many questions and concepts left unanswered. I went in without having played Fallen London (though I did go back and play it once I was hooked on Sunless Sea) and my mind immediately was grabbed by the implications of what was going on in the game world around me. I loved the content and the lore that the world seemed to be steeped in, and loved it even more for the fact that it didn't give up its secrets without its due. This game is primarily an exploration game with the pretense of combat and economics, though those are not the primary focus. That said, I very much enjoy the combat and trading aspect, but it does come easier as you get more established. It is the process of becoming established that I think turns so many initial players away.

The game starts you off with very blessed little to begin with, other than a book of tips that you can sell for some much needed cash. I very much felt like a struggling captain attempting to eke out a living and a place in an uncaring and darkened void. Again, this can easily be a turn off to players who are wanting a power play game or one in which the story is driven forward regardless of choices and actions. From the get-go, Sunless Sea made me work for what I wanted. To be honest, I wondered about whether I was doing the right thing or if I should start over from scratch. It was these hardships and questions that truly began to build my utter appreciation for the game. To reiterate: I felt like a helpless captain, questioning his choice to set sail. I struggled with how far to venture, especially as resources were scarce early on (a pivotal point of the game being resource management). I kept to certain routes and ports which I knew were safe. Eventually however, I came to a crossroads in which I had to choose to stagnate or press outwards. Obviously, I pressed on, and came to many new ports, stories, and struggles, each one a new opportunity for something engaging, thrilling, or even dangerous. It was this story-driven, choice-balancing, and ultimately life-imitating work of art that got its nets over me, hooks in me, and dragged me down to the depths.

This is all to say that I loved and continue to love this game. I eagerly await new stories and the expansion pack due out soon. That also said, this game isn't for everyone, and eventually, as with all things, it can get stale. I myself took a break from it for a few months, but eventually returned to continue on for some reason or another. The magical part is that, while I have seen what I would call the vast majority of the story content, upon my return to the game, I found myself experiencing just a few storylets I had *never* seen before.

If you are feeling particulary narrative hungry, while still challenging yourself to a harder-than-average starting learning curve, this game is most assuredly for you. Just be aware that this game is very much what you make of it. Put yourself into the game as the captain. Don't just play, experience.

*Edited for spelling.

This is a GREAT game. If you're ok with reading a bunch of text, and if you're a sucker for mysteries, this game is definitely for you.

Start with reading through the tutorial book. It might seem long after a couple pages, but keep reading and you'll want more. Way more. That's your ticket to Sunless Sea.

The game has a horror theme to it, and while it might generally not be scary (with a possible few exeptions, depending on the player), there's suspense, places that send chills down your spine, a generall creepiness and most importantly: the unknown.

There is a "Merciful" mode that lets you save and load manually, (the normal mode relies solely on auto-saves) but I would STRONGLY RECOMMEND AGAINST IT! It might be tempting, but ultimately it is a bad thing, in more ways than one. You might be thinking "If I mess up, that's a good thing, right?". NO! Because if you mess up (especially if it's your first couple of captains) you've probably messed up WAY before you noticed it, maybe even from the start.

The best way of playing this game is definitely in the standard mode. When (yes, when) your captain dies, your next captain inherits something from you previous one (you can choose what that is) and most importantly, even if the game seemingly starts over, the sea layout is re-randomized, and such, you still have a very important thing: Knowledge. Knowledge of what happend to your previous captain, what you discovered with him/her and how they perished, to name a few things. All of which are very important for making your next captain have a better journey, and get closer to his/her goal (the goal you set for your captain determines what you have to do to "win" the game and are exclusive to each captain, meaning new captain, start over). You may think that starting over like this would simply be like staring over any other game, such as making an alt character, but it's not. The game continues, in a sece, because of the above stated reasons.

Now, may you have fortune in your voyage at the unterzee.

Excellent story telling, and you begin utterly rubbish at staying alive but soon learn how to keep yourself and your crew from going utterly mad and eating one another. It is always a tight thing to survive and earn enough by gathering intelligence, and it is so atmospheric travelling around sunken london. The sound track is also brilliant.

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.

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

Sunless Sea is the game you play specifically for the adventure along the way, not for the end-goal. At least in my perspective, anyway. The stories that create this world as you expand it in your quest for new trading, jobs and what-not fill this world with the strange, mysterious and compelling depth that makes up the Unterzee. Whether it's bolstering my chosen side in the Pygmie/Rat war or climbing an ice tower full of pure horror to search for my character's True Name, I know that each zailor in my line will have a unique and satisfying outing until Mt. Nomad kills me... again.

Rogue-like. We hear it all the time. This game is truly of the genre and not "I make a decision and hope the next room is better", which isn't Rogue-like, but simply moving from one random encounter to another.

This game feels like a breath of fresh air to an old-school gamer like myself. It goes back to the days of 16-bit computing when saves were few, death was a real thing to try to not have happen, and the story and theme were at the forefront of the experience, because graphics were not the focus. It reminds me of games like Escape Velocity, Angband, Star Control 2, and many other classic games of that era. This game feels like there is an entire MMO or RPG setting behind it, and the onine community is great. What you get is a compelling and unique story that feels like it has real characters and a unique and dark atmosphere befitting a roguelike game. More than one time I've jumped in my seat or had those stressful moments of trying to figure out how to work out a solution. Not in a chess-like fashion, but more of a "it's going to eat me if I undock now..." Quite literally in a few cases. This is an odd and grim world and the Zee is vast and dark...

Yes, resources are hard to get at first. You will die. Quite a few times. There is no manual/training mode, so you have to figure things out yourself. You can play for hours and still not see the entire map or know half of the stories. And more keep being added, all slightly eery and definitely the result of a warped mind. But like all good games, it is very rewarding once you start to figure it out.

This is my #1 recommended game of the year on Steam. It says that I've played 9 hours online, but the game works better/syncs with the company's sever much better if you run it outside of Steam, where I have several hundred hours of play.

If you are running XP or Vista and can't get it to connect or start up, I wrote a FAQ as well on getting it to run. Check the forums.

Dark and creepy
Huge depth of play. A truly unique setting.
Experiment and die. Experiment some more. And die.
And eat your crew. But that's a secret you tell no one...

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.

Vast, Haunting, Terrifying.

Almost perfect.


Cons: there's no real aim, bigger boat, more crew, but all you do is absorb the world.

Probably in the Top 5 games I've ever played. My hours in it aren't the highest in any game by any means, and I bet you could get at least 10 times the amount that I put into the game and still find it fun, but I just got hooked on other games. The story is awesome and so is the art and music. Never will there be a game that surpasses Sunless Sea as a great story driven game
