If the dark creatures of the sea don’t get you, the madness will. Sunless Sea is a rogue-like exploration RPG where you play the captain of a ship traveling through the enormous and perilous underground ocean known as the Unterzee. Featuring real-time combat, beautiful hand-drawn art, and unforgettable storytelling, Sunless Sea will drag you deep into its black and merciless world.
Explore a strange, Gothic, Lovecraft-inspired world far from the reach of the sun, filled with vile creatures such as enormous bats, deadly sentient icebergs, and tentacled monstrosities.
Trade with far-flung lands and make your name as a captain. Every port bears its own dangers, but also the promise of riches.
Manage your fuel and food. The last thing you want is to run out of fuel in the middle of the cavernous darkness. Run out of food at a crucial time, and your crew may end up on the menu.
Upgrade your ship with better cannons and engines. All the better to outfight or outrun whatever is stalking you in the deep.
Gather a motley crew to help you on your journey. Each crew member has a story to tell if you can convince them to share it.
Pass on your ship and riches to the next generation. Your captain is mortal but their name and fame may last beyond one lifetime.
Beware when the Zee-fever catches you; each return to its cold embrace may be your last.
