Battlefield 1 will have an open beta test soon, actually sooner than we think. According to EA and DICE, Battlefield 1 Open Beta will start on August 31st for Xbox One, PlayStation 4, and Origin for PC and Sinai Desert Map will be included.
There are two game modes which Battlefield 1 Open Beta will support: Conquest and Rush.
RushA 24-player mode where the Attacking force must find and destroy the Defending force's Telegraph Posts, which can be used to call in artillery strikes. The Defenders can deny the Attackers their mission by disarming explosives they plant on the telegraph positions. Should the Telegraph Posts be destroyed, the Defenders must fall back to the next sector and protect the Telegraph Posts there.
ConquestAn all-time fan favorite of Battlefield players, Conquest is a large-scale game mode with up to 64 players fighting for the control of key objectives. With large armies on foot or behind the wheel and the addition of fearsome Behemoths, Conquest brings together all the elements of the signature Battlefield All-Out War.
If you are a Battlefield Insider, you get early access and if you sign up by August 21, you can be a Battlefield Insider member and experience the Open Beta.
