EXO Flight Tests
EXO Flight Test (EFT), or commonly Public Test Realm (PTR), and previously the Experimental Build, is an opt-in test build of Astroneer that enables players to test and play the latest patch before it is fully released.

How To Join
Open Steam, right click on "Astroneer" in the library, and then click "Properties". Navigate to the "betas" tab and in the dropdown, there should be the branch "exo_flight_test". Click on it and press enter, and then Steam will begin downloading the EFT version of the game.
