In confirming Xbox One as one of Battlefield 4's platforms, EA also took the time today to reveal the first expansion pack for the highly anticipated shooter.

Battlefield 4: China Rising will be available at launch and come free with any pre-order of the game. It contains four "massive" maps spanning across the "vast and majestic" China mainland. It also includes all-new vehicles and "high-tech military equipment." That's about all we know at this point.

Battlefield 4 is set to release on October 29 for Xbox 360, PS3, and PC. No release date was mentioned for the Xbox One or PS4 versions, debunking earlier rumors stemming from a tweet that suggested that both consoles could be released prior to that date.
