Sunless Sea

[Mark-x]

 There's nowhere like the Unterzee. Sunless Sea's foreboding underground ocean is an abyss full of horrors and threats to the sanity of the crews that sail upon it. In your vulnerable little steamboat, you have to navigate these waters, trading, fighting and going on bizarre adventures on islands filled with giant mushrooms or rodents engaged in a civil war. 

It's often strikingly pretty, but text drives Sunless Sea. Like Failbetter Games' browser-based Fallen London, it's drenched in beautifully written quests, dialogue and descriptions. And it's not restricted to gothic horror, though there's plenty of it. Your journey across the black waters is just as likely to be whimsical and silly. Always, though, there's something sinister lurking nearby. Something not quite right.
