Experimental Build

How to Join (Steam)
In your Steam library:

Right Click on Astroneer > Properties > Betas tab > From the drop down select, "experimental - Latest untested builds" > Hit 'Close'

Steam should automatically grab that build. Once it's done, run the game. You're now running the Experimental build of Astroneer. When you want to go back to the MAIN build, repeat these steps but choose "NONE" from the drop down list in 'Betas' tab.
 * NOTE: Your save games will not be compatible with the Experimental build of the game. When we push this update to the main build of the game your save games will (should?) still be compatible. You will be starting a fresh game whenever playing a new Experimental build.
