The first-person shooter video game has been played by in excess of 21 million as of June, according to EA, the American publisher.
Andrew Wilson, the CEO of EA, said: "In 'Battlefield 1', our community has grown to 21 million unique players experiencing an extensive live service, with monthly updates, in-game events and missions, and the largest expansion packs in franchise history."
Wilson also teased that fans will hear about a new offering at Gamescom next month, promising it will "bring the richest 'Battlefield 1' experience yet".
He explained: "At Gamescom, we will detail our plans for a new offering that will bring the richest 'Battlefield 1' experience yet - including the all-out warfare, epic multiplayer battles and War Stories campaign that have defined the game, plus new maps, deeper progression, and additional fan-favourite game modes, all in a single package."
What's more, EA plans to reveal a new eSports mode, based on fan feedback, at Gamescom.
Wilson said: "We'll debut a new way to play 'Battlefield 1' built for competition and designed with direct input from our 'Battlefield' community.
"Through a growing portfolio of digital and traditional broadcast deals, our spectator reach will continue to expand, with major brands set to engage this high-value audience through global sponsorships."
