Captain a spacefaring steam locomotive as a new Victorian empire takes to the stars! Lead your hapless crew into trouble – and out of their minds. Smuggle souls. Barter for barrels of time. Stop for cricket (and a nice cup of tea).

Sunless Skies: Sovereign Edition is the complete and definitive version of Sunless Skies. It incorporates the many additions made since launch – including new officers, enemies, engines, stories, and mascots, as well as a completely reworked region, a full steam mode for long journeys and desperate escapes, and the much-requested horn – as well as dozens of quality of life improvements.

Create your past

Choose who you were before you became a skyfarer. An urchin? A priest? A revolutionary? What brought you here, and what are you hiding?

Each time your character advances, choose another facet of their history. Were they the Black Sheep of the family? Do they have a Lost Love?
The skies are cruel. Most of your captains will die. But each will leave their mark on the world, and an inheritance for those who follow – for better or worse.

Explore a beautiful, hostile universe

Discover more of the deep, dark, marvellous Fallen London Universe, as seen in our previous game, Sunless Sea. (But you don’t have to play that first! This is a totally new story, not a sequel.)

Improve your locomotive

Your locomotive is all that stands between you and the many dangers of the Heavens. Maintain and upgrade it with exotic weaponry and equipment, like a Pneumatic Mining Array, or the rapid-fire Brassraven. Learn how to craft exotic weapons like the Wrath of Heaven from your defeated enemies. And when you have enough funds, buy an entirely new one! Perhaps you would enjoy the capacity of the Pellinore-class Trader? Or the sleek malevolence of a Medea-class Destroyer?

Fight marauders, Her Majesty’s agents, and abominations of the skies

Face rival locomotives – anything from scrappy pirates to experimental warships of the imperial navy. Battle monsters like the nightmarish Undeparted, or swarms of irate Chorister-bees. Play different factions against each other, and learn the unique behaviours of each foe. Use Full Steam mode to evade trouble or chase down your quarry.

Survive starvation, madness and terror

Manage your crew’s morale and your captain’s own nightmares. Balance your fuel and supplies against your desire to explore new horizons, or pursue knowledge, or seize riches.
Beware: we are all changed by the dark.

Recruit variously helpful officers

Populate your ship with upgradeable officers, each with their own quest to fulfill: a repentant devil, an incognito princess, an entire brigade of rats, and – dear god! – your own Aunt?! How did she get out here?

The World

Unfettered by gravity, the Victorian Empire begins to reach across the skies. It has built a new sun. The Empress reigns from the Throne of Hours, which gives her control over time. Its ambition is vast; its mercy slim.
The High Wilderness is a wondrous, horrifying vision of space where the rules are not as we imagined. Winds howl through shattered celestial ruins. Fogs coil amidst stellar jungles. Industrial sprawl chokes the heavens with smog.
The stars are alive. They are the Judgements: vast intelligences that govern all things. But they are dying. One by one, something is snuffing them out, leaving their thrones empty.
Your captain must make their way in this impossible world as they trade, explore, fight and survive. Pick your side carefully, for you might be the thing that tips the balance of power – will you support Her Majesty's new empire, or the rebels who mean to throw off London's rule? Or perhaps you spurn such concerns, and intend to chart the narrow course between the two? Will you retire triumphant, or be lost to the dark?

  • Failbetter finally balances smart gameplay and ingenious prose in this poignant saga of mortality, writ large.

  • Sunless Skies' bleak pondering of cosmic horror and colonialism is probably one of the best game narratives of 2019, and one that deserves to be experienced.

  • A wonderfully refined sequel that takes everything that was great about the original and expands and improves upon it, making for a much more accessible experience for everyone.

  • Sunless Skies is an excellent game that rewards commitment to its steady pace and steep learning curve. A web of plots and places suggest the infinity of the heavens, but even infinity must end; in this case, it stretches across a million words or so and easily forty hours. The story doesn’t explore every nuance introduced, but that’s a running problem when writers seek to explain the ways of the heavens to mortals. Like many powerful, unique titles, Sunless Skies leaves the player with the desire for more, not because it’s lacking but because it appeals to the mania to solve every mystery, plumb every depth.

  • Failbetter’s strange brand of Victorian fantasy meshes with the game’s measured resource management and dangerous combat to define a truly rich role to play, one that inevitably gives way to moral compromise as you operate, with some struggle and no small amount of complicity, under capitalism.

  • Failbetter continues to revolutionise the RPG - not by burning it all down, but by slipping pages of prose into every crevice it can.

  • Over the couple dozen hours I’ve spent on my current adventure, I’ve made horrible deals with cunning people, lost crew members on woefully unprepared expeditions, and have generally huddled before my monitor waiting for the next calamity.

  • It is challenging, yes, but the sensations that it makes you feel are fantastic and they are a big image about the greatness of this adventure.

  • In the end, what Sunless Skies does do best is harness curiosity. I often found myself travelling to small hubs for specific quests, only to leave with a whole new set of stories, well beyond what I had expected. Each location is so lovingly crafted that even the darkest of places shines. With the combination of incredibly skilled and extensive writing and haunting and varied artwork, Sunless Skies has to be one of the most atmospheric game worlds I’ve ever played within.

  • Edge Magazine

    This is a game about stories that has a knack of producing really good ones - when you're doing well, and especially when you're doing badly. [March 2019, p.120]

  • With impeccable world-building and compelling exploration, Sunless Skies is a haunting journey that is worth traversing time and time again.

  • Sunless Skies delivers in ways you don't even expect it to. The atmosphere is incredible, and the stories almost addictive. The world is beautiful and the danger is tantalizing. It might be deadly, but it's well worth the trip.

  • If you like expansive RPGs with engaging combat, a beautiful setting, and near-limitless roleplay potential, then Sunless Skies is definitely for you. For just $25, this is one of the best games you can get on PC right now.

  • The sharpest writing around, wrapped inside a surprising adventure that’s tough but rarely unfair. Failbetter’s finest hour.

  • If you like well written stories and an atmospheric world, the follow-up to Sunless Seas might just be the game you want.

  • Sunless Skies is a strange amalgamation of genres with even stranger stories to tell, but the weird world and nightmarish encounters come together to create something special. Combat and repetition may weigh down the Homeric adventure, but the overall journey is well worth the ticket.

  • Anything with this much text is going to feel slow-paced, and that is for the best. Despite being loads more forgiving than the first brutal installment, Sunless Skies is wicked hard. I’ve only seen half of the games star systems, I’ve botched major quests and started again, and died a dozen times in an hour. But every setback is a learning experience. Some games you play until you get stuck or bored and you quit. Not so with Sunless Skies. Even if I don’t boot it up for a while, I know I’ll be jonesing to captain my locomotive again many, many times.

  • Sunless Skies is a refined and more organic successor to Sunless Sea. The skies above London are full of intriguing events and charming characters depicted through a fancy, sharp and magnetic writing. The hybrid gameplay which mixes “choose your own adventure” elements with a classic RPG/roguelite scheme works well and offer a deep and satisfying experience. If you don’t mind read walls of text and embrace the rhythm of the slow gaming, Sunless Skies is one of the best games around.

  • It's an amazing journey — clever, spectacular and exciting. Fire up your furnaces, ladies and gentlemen, but don't forget how treacherous those twinkling stars can be.

  • Sunless Skies is another well-written story from Failbetter Games. The story and setting carry the game, but the combat mechanics can take some getting used to and may feel limiting. If you like your stories thick in the dark and strange ways of things like H.P. Lovecraft than this could very well be your cup of maddening tea. And you do like tea, don’t you? Of course you do, the Queen wouldn’t allow it to be otherwise and She is watching, always watching.

  • Just like the other two titles developed by Failbetter, Sunless Skies is not a game for everybody. It has a very slow rhythm and demands that you read a lot in order to understand the story. So if you are not into reading or patient enough, you'll probably get bored in the first few hours. But if you give it time and get along with its rhythm, you'll definitely have a wonderful experience.

  • Sunless Skies is an amazing surprise. It is a very solid RPG and strategy game, and its narrative is one of the best we’ve seen in years.

  • The roguelike Sunless Skies is more accessible than its predecessor and thrilling like a good book through its exciting stories.

  • Sunless Skies is a worthy sequel to Sunless Seas, which maintains the main features by improving certain aspects such as the user interface and the combat system.

  • At times serene and at times unnerving, Sunless Skies epitomizes an atmospheric narrative-driven exploration into strange and unknown locales, only marred by the tedium that grows as the novelty eventually wears off after a few hours.

  • Sunless Skies doesn’t paint an entirely convincing picture of interplanetary travel. Your locomotive, for instance, sails between points on a flat surface, giving it the feel of seafaring with a cosmic paint job. But better to compromise there than in style, imagination and atmosphere. Sunless Skies has that in spades.

  • At its best, Sunless Skies is a triumph. Its writers have crafted a world of endless wonder where seemingly anything is possible. At heart, it's a text adventure that conjures the imagination to send you on a journey as spectacular and memorable as any big-budget graphical blockbuster.

  • With its captivating prose, Sunless Skies will certainly scratch the narrative itch of its niche audience, but the lack of innovation in the gameplay department threatens to prevent new fans from being drawn in. Too often the rudimentary gameplay and masterful plot find each other at odds, and in both cases the player ends up being the victim.

  • A jewel made of words - beautiful, bewitching words. When you’re reading its stories, everything seems great, but then the game lets itself down with low difficulty and monotonous activities.

  • Sunless Skies is a real "interactive book". In the new game of Failbetter Games there are texts of a really rare quality for a video game, like a good sci-fi novel. Too bad that the strength of Sunless Skies is also its greatest limit: there are often long sequences of readings a bit too verbose and ends in themselves.
