Bethesda has confirmed a public test server for Fallout 76 is slated to roll out next year.
“A Public Test Server (PTS) is currently in the works with the hope to get it up and running in 2020,” Bethesda said in a brief update on its official blog. “Once we’ve figured out all (or most of) the kinks, we will be able to provide more details on our PTS and how you can participate.”
The update gave no specific window on when the PTS might be available, so it’s probably better to expect it later rather than sooner.
