Following the release of the latest update for Battlefield 4 on PC some players appear to have acquired the weapons and gadgets that are due to be deployed in the China Rising DLC.
China Rising is set for release on December 3rd for Battlefield premium members and two weeks later for non-premium players but you can check out two videos below showing what you'll be getting with the expansion.
The new weapons you're seeing in the videos are the the L96A1 sniper rifle, MTAR-21 carbine, MP7 personal defense weapon, RPK-74M light machine gun, and the L85A2 assault rifle, as well as two new gadgets; the SUAV and the UCAV.
DICE has also detailed the latest server update on the Battlelog:
“We are seeing a lot of server crashes at the moment. These are being solved by rolling out a new server patch on PC (Server Update R10). It will take a few hours for this new server version to propagate, but it should be with most servers in a matter of a couple of hours.
"If you are getting error messages referring to the China Rising expansion pack when trying to join a multiplayer server, please try another server. This error will only appear if a server has not yet updated from server version R9 to R10.”
Presumably the update, R10, is intended to patch the problems presented when users gained early access to China Rising.
