Update 19 :: Welcome To The Workshop

Howdy Pioneers!

Update 19 is now live on Steam! A big thank you to those that helped test the new mod system. A special thank you to Ellmite for helping track down a lot of hard coded language strings and the first translation mod on the Steam Workshop.


Official Mod integration is here and supports translations and gameplay tweaks. The Steam Workshop has been integrated into the new Mod Manager interface. Mod creators can upload their mod to the workshop and users can subscribe to mods on the Workshop for use in their game.

Planet Map Display Modes

A new piece of equipment can be crafted and installed into the Map Table to to unlock display modes. The new display modes visualize data for discovered biomes, temperature, elevation, moisture and available resources.

Localization Support

Part of the focus of adding mod support is to enable the creation and usage of language translations. While the core game includes English, the Steam Workshop is available for players to create and use language mods for additional languages.

If using a language mod be sure to change the active language in settings after the mod is enabled in the Mod Manager. A German Translation of the game is available on the Workshop with more languages to follow.

If you’re interested in translating the game, please check out the Language Translation Guide.
