Important

There are a few important things to keep in mind regarding this Open Beta build:

  • Old saves are not supported anymore. This includes the saves from the Experimental branch, if you have played it recently. This build requires starting a new game.

  • Translations and new voice-overs are not ready on Open Beta. This build is available in English only.

  • As mentioned at the beginning, this build can be unstable. If you are after a polished, stable experience, it's recommended to wait until Major Update #6 is available on the Default branch.

  • Don't forget to share your feedback with us and send bug reports via the in-game Bug Reporter (available after pressing the ESC button). Bugs reported this way are 10x more useful to us, as we can load up your save and analyze what exactly went wrong.
