User blog comment:Conqueror of all Zombies/What would you like to see in Battlefield 3?/@comment-28584497-20110808004647

If it's truly a sequel to BF2, then what happened following the global war with the PLA and MEC could be anyone's guess. However, considering that the U.S. is in the middle east, it seems likely that the MEC -- and their allies, the PLA -- were defeated.
