Battlefield 4: China Rising is now available to download to all Premium members on all platforms.

The expansion pack introduces 4 new 'massive' maps - Silk Road, Altai Range, Guilin Peaks, and Dragon Pass - and 2 new vehicles - Battlefield 3: End Game's dirt bike and a brand new bomber.

In addition, the DLC includes an Unmanned Combat Aerial Vehicle for the Support class, a Small Unmanned Aerial Vehicle for the Recon class, Air Superiority mode, 5 new weapons and 10 new assignments.

The DLC will be available exclusively to Premium members for 2 weeks, after which it will be available for purchase to non-Premium members. If you received a code for China Rising with your copy of Battlefield 4, you'll be able to download the DLC in 2 weeks' time.

China Rising is the second expansion pack to launch for Battlefield 4, but the first available outside of Xbox One.

Battlefield 4: Second Assault, which launched exclusively to Xbox One Premium members on November 22, is also available to download to all Xbox One players today.

The expansion includes four Battlefield 3 maps remade for Battlefield 4, including Operation Metro, Caspian Border, Gulf of Oman and Operation Firestorm.
