When Fallout 76’s B.E.T.A. (Break-It Early Test Application) arrives in October, it will be the full game and any progress made will carry over into the launch version.
Revealed in the Fallout 76 B.E.T.A FAQ, Bethesda states that the “current plan for the B.E.T.A. is it will be the full game and all your progress is saved for launch.”
The FAQ also notes that there will be no NDA so players will be able to discuss, post screenshots, stream, etc. when they begin playing.
A couple weeks ago, community administrator Jurassica revealed that the B.E.T.A. would begin in October and Bethesda would be “selecting people who have pre-ordered the game from a participating retailer.” She also confirmed that they would “start small and grow over time.”
