When was Sunless Skies released?

It was released on 31st January 2019 for Steam or GOG, after being in early access.

What kind of game is Sunless Skies?

Sunless Skies is a gothic horror roleplay game with a focus on exploration and exquisite storytelling for PC, Mac and Linux.

You can purchase the game either on Steam or GOG.

I found a bug! / I have feedback! Where do I send it?

Sunless Skies now has an in-game feedback and bug reporting tool which is accessible by pressing F8, or via the Give Feedback button on the pause menu. Once open you should select an appropriate category from the dropdown list (Feedback, Narrative Issue, or Other Issue) before entering a description. The more information you can give us about the steps you took before encountering an issue the better.

If you cannot launch the game in order to access the bug reporter, then please see our official Troubleshooting Guide. This comprehensive guide covers crashes, black screens, and all manner of start-up issues, including details on how to repair your save files if they become corrupt.

If you’d like to join more general discussions about the game or its gameplay, you can visit any of our forums: Steam, GOG, Reddit, Discord or the Failbetter Sunless Skies forum.

 What controls are currently available? / What about accessibility features?

Sunless Skies currently supports keyboard and mouse and wired controllers. The UI is better and more readable than the UI in Sunless Sea. There’s a setting to increase the font size. There are also settings which allow you to alter the challenge level to your preference:

  • Aiming Assistance – determines how many player weapons arc towards targets and how aggressively they do so.
  • Enemy Projectile Speed – determines the speed of enemy bullets making them easier to dodge.
  • Supply Consumption – determines how long Fuel and Supplies last.

 Will it be coming out on Switch / PS4 / mobile etc?

Yes! The highly polished and perfected Sunless Skies: Sovereign Edition will be coming out on PC, Nintendo Switch, PS4 and Xbox One. More on that here.

 Will the Sovereign Edition be compatible with older save files?

Yes. Please note: once you load an old save in the Sovereign Edition you won’t then be able to load that save in an older version of the game.

 Will you release a translation into Russian/Chinese/Spanish?

While we’d love to localise Sunless Skies into all sorts of languages, we’re only releasing the game in English. When you consider the word count (almost 800,000 words), our distinct Failbetter style, the admin burden and the technical challenges involved, localisation isn’t a straightforward option for us. We’d like to explore localisation for future projects!

 Will you support modding for Sunless Skies?

Unfortunately not. The game wasn’t really built to support modding, and we’ve reluctantly concluded it would be a very large amount of work to do so at this stage. In future, we intend to give more consideration to the ramifications of our development choices on the possibility of mod support, so that we can hopefully provide it in games for which there might be community modding interest.

 I want to record a let’s play or a first impressions video of your game. Is it okay for me to stream or upload footage?

Yes, please do! You’re also welcome to monetise the videos for any of our games. We’d appreciate a link to our Steam page, if you’re able!
