A picture sent to MP1st contains an alleged screenshot of a post on Battlefield 4's Spanish Facebook page. It states that the four multiplayer maps added by China Rising will be Taklamakan, Altai Range, Guilin Peaks, and Dragon Pass. Also to be added (that wasn't known before) are five new weapons and ten new assignments.
This comes after news that the achievements for the expansion revealed the dirt bikes and Air Superiority from Battlefield 3: End Game will make their return. There's not much to go on here outside of just names, but if my imagination is anything to be believed Dragon Pass is definitely something to look out for when China Rising releases in December.
