It's scheduled to kick off on August 31 for everyone on PlayStation 4, Xbox One, and PC.
You may be able to play earlier than that, however, as Battlefield Insiders can jump in a day early, starting August 30.
To be able to play early, you needed to have signed up for the free Insider program by August 21 and made a platform preference selection.
With the beta scheduled to begin tomorrow for Insiders, we'd expect codes to go out soon.
The Battlefield 1 beta takes players to the Sinai Desert map, which features horseback combat, a deadly armored train, planes, and more.
