LOSE YOUR MIND. EAT YOUR CREW. DIE. Failbetter’s award-winning PC game is now on iOS! 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. REVIEWS - “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) - “Sunless Sea's method of storytelling isn't unique, but it has never been realised with such impact and elegance.” (10/10 – Eurogamer)
