About SUNLESS SEA
LOSE YOUR MIND. EAT YOUR CREW. DIE.
Sunless Sea is a Gothic Horror RPG with a focus on exploration, exquisite storytelling and frequent death.
Captain a Victorian steamship on a vast underground sea
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.
Seek out intriguing individuals for your crew
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.
Stray from the gas-lamps of civilisation
Light and dark, terror and madness: spend too long on the wide, dark sea and your crew will grow fearful and eventually lose their sanity.
Carve a life for your captain in a cruel and unique world
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.
Your captain will die.
Pass on resources from one generation to the next. Acquire a family home and a hoard of heirlooms. Build a legacy of zailors who braved the sea and lost - or, occasionally, won.
Features
- Beautiful, hand drawn art - castles of sparkling ice, prisons perched on lily pads, fog-shrouded lighthouses and the DAWN MACHINE.
- Real-time combat against ships and Zee-beasts, spider-crewed dreadnoughts and sentient icebergs.
- Upgrade your steamship with powerful engines, cannons and pneumatic torpedo guns. (Or buy a bigger, better ship.)
- 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.
