Battlefield Insider players get the first shot at the open beta, and EA wants players signed up by August 21. You can head over to the Battlefield Insider page to join the party. If you already have a Battlefield Insider account, you still need to head over to the page in order to set your platform preference.
The open beta will focus on the Sinai Desert map, with two gameplay modes.
"The Battlefield 1 Open Beta will include the Sinai Desert map, a scorching hot battlefield located just East of El-Jifar," explained EA in the announcement post. "From infantry skirmishes in the narrow streets of the village of Bir el Mazar to dogfights above the majestic cliffs, you'll need to make tactical use of the dunes as you engage in explosive battles."
The first mode will be Conquest, a 64-player skimish where two sides are fighting for control of various map points. Conquest also includes one of the game's Behemoth class vehicles, the fearsome Armored Train. The second mode is Rush, a 24-player mode that has attackers taking out the defending army's Telegraph Posts. This mode is reminiscent of Star Wars: Battlefront's Walker Assault, where the defending army can use the telegraph posts to call in artillery strikes.
EA DICE has yet to release the PC system requirements for Battlefield 1.
