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?

We’ll certainly consider ports, but right now we’re in post-launch bugfixing and performance improvement mode.

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!

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!
