Zubmariner update: Unknown Depths

Hello, delicious zailors!

We present a further look into the depths of the Unterzee!

View this post with the images on our blog

Zubmariner will be the first major piece of DLC for Sunless Sea. Equip a zubmersible add-on to your ship of choice, and explore the profound darkness beneath the Sunless Sea.

Unterzee living

We're continuing work on concepts for cities and terrain on the Zee floor.

Dahut is a brightly coloured pastoral wonderland, populated by Drownies.

An exploration into the possibilities of Under-Unterzee housing.

Unknown Depths

Diving beneath the surface will never be safe, and you will never be certain what you will find down there. However, the rewards could be great...

One of the core concepts in Sunless Sea is venturing into unfamiliar waters. Closer to home, the locations are more fixed. Further out, you can’t be sure if that island you stopped off at to pick up much-needed supplies will be there. And out in the wilds, you can never be sure what you are going to find.

In Zubmariner far more of the layout will be unknown to you.

To achieve this, we’re using procedural generation to populate the areas beneath the surface. Whenever you start a captain with a new map, the game will furnish the seabed with random rocks, coral outcroppings, fissures and debris.

Some example terrain types

Each area of the Unterzee will have unique types of terrain that can appear within it, and the density of the terrain will vary from location to location.

We’re working on tools to help tweak these density values and ensure the right amount of coverage for all the different areas of the game. This will be coupled with a method for ensuring that terrain isn’t accidentally placed too close together, so we can be certain that players (and predators) can navigate down in the depths. You might end up with a nice, clear path to your destination, or have to tackle a network of subsurface obstacles.

In addition to the terrain, there will also be randomized enemies to fight, threats to avoid and treasures to retrieve down on the ocean floor.

We’re implementing new spawning methods to ensure we have toothsome opportunities waiting for you each time you dive. A Favorable current might speed you on your way or the skeletal remains of an extinct species may have been exposed, ready for you to examine it and bring your findings back to London.

Journeying on the surface is a fairly consistent experience once you have learned the routes between ports, but there’s never any certainty in what you will encounter on the Unterzee floor.

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?

This game is beautiful, but you do not play it for its beauty.

This game is hard, but you do not play it for its difficulty.

This game is sonorous, but you do not play it for its melody.

You play this game because its world has its tentacles in you, not just literally, but figuratively. Because you've seen some things that can't be unseen and even if the character that actually saw them is five generations distant, having fallen afoul of some mass of flesh, you can't sleep until those mysteries are resolved. Because you think this time, this time will be the time you do it right and you find out what it all means.

And you don't. And you die. Or worse.

But you saw some new things and you lost in a new way and those scrabbling bits of beautiful, crisp prose, evocative yet still economical, the work of someone who has been honing their hand at writing faux-Victorian video game text for the better part of a decade, those bits of prose unfold yet more of this wondrous world and feed your addiction and before you know it you've selected a legacy and rolled another character and oh, hell, here we go again. Yes, Admiral, I'd like another mission.

Buy this game. It'll make you eat your mind. It's very persuasive like that. And you'll have such a great time doing it.

You can grind if you want to
You can leave your friends behind
'Cause your friends don't grind and if they don't grind
Well they're...actually playing the game how it's supposed to be played...

Despite what every other negative review says, grinding is the absolute worst way to go about making money and upgrading your ship. The best way to actually upgrade your ship is to explore and complete stories (missions)...seriously, explore *everything*, take chances, complete stories, and you will end up with more money than you actually know what to do with.

Already been someplace? Good, go there again (and again); every time you dock somewhere, you have a chance of encountering a different story that you haven't encountered yet. If you are relying on grinding, then you are making a chore out of something in the most unnecessary manner possible.

TLDR (you probably have ADHD) - Do stories, make money, upgrade you ship, don't bother grinding.

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.

This is a bit of a challenging review to write. While I love the concept behind Sunless Sea a lot, and it definitely nails it when it comes to tone and atmosphere, but the game itself has some fundamental flaws that erode its fun factor a lot.

The good: Graphically, it is a rather beautiful game, depicting its underground sea in an almost painterly way. It captures the rich, dark, almost Lovecraftian tone of it's world perfectly; and the artwork it uses to represent the characters and creatures populating that world are great too. It's writing its fantastic, fo rthe most part, and make me wish there was a straightup novel I could buy that would let me dive more deeply into its mythos. The gameplay itself is a rather simple top-down view of your ship, but it is effective, fun, and evocative of older sailing titles from the 90's like Sid Meyer's Pirates.

The bad: The game is designed around perma-death, and while that is actually a feature that drew me to the title in the first place, it doesn't really work here. You are going to die... a lot... and unless you managed to advance to the point in the game where you can pass things along to an heir, which is NOT an easy task, that means you have to start all over again. By the fifth or sixth attempt, it grows really repetitive to have to re-find the same officers, have the same conversations, re-encounter at the same obstacles at the same ports, and re-read the same blocks of text (no matter how brilliantly written). In the end, after my ninth captain went down with his beautiful customized ship, I just didn't have it in me to start in a crappy little boat all over again.

The bottom line: I'm still recommending you buy this game, if you can get it on sale, so that you can experience the good stuff it does have to offer... but be aware that it does have some flaws that will become increasingly hard to overlook. 3 out of 5.
