About SUNLESS SEA
SUNLESS SEA is a dark exploration game from Failbetter Games, set in the gothic Victorian world of Fallen London. You captain a steamship on a vast underground sea, trading, exploring strange islands and managing fuel, food and your crew's sanity, with death never far away. The writing is the star, full of eerie stories. It is single player. It needs very little power, so any of our gaming PCs handles it easily.
What SUNLESS SEA needs
In plain words: to play at all it needs almost any graphics, even the graphics built into the processor, with at least 1GB of memory.

Will my computer play SUNLESS SEA?
On most computers we find the graphics card for you. Add your processor and memory, and we will tell you if it plays, and what to upgrade if not.
A low-spec PC or a high-spec PC?
This is a light game: almost any of our gaming PCs will run it comfortably.
On a PC that only just meets the minimum, the game will start and play, but on low settings: simpler shadows and textures, shorter view distances and fewer frames each second, so fast moments can feel less smooth. A 1080p screen is the sensible match.
On a PC that meets or beats the recommended spec, you can turn the settings up: sharper textures, proper shadows and lighting, more detail in the distance, and a smoother picture. A stronger PC also lets you use a sharper 1440p or high-refresh screen.
