Only started playing a week ago, but I love the direction the game is headed. New content is starting to look like a flushed out mmo more and more, and it’s super exciting!
I seem to be having trouble figuring out how to sign up for the test versions on steam however, is it possible anyone could shed some light on this for me? 
In your steam library, right click boundless, click properties.
Go to the beta tab and use the drop down arrow to select the test version.
The game will do a quick update and then you can start it like normal and you will begin the test version.
Do the same thing to change it back to the live version.
I like the look of these small structures I can see that exploring the world will become much more fun if there were locations where I could stumble upon something like that
