Hey there, this isn't a specific Battlefield 4 map. Think of it more like, we're returning to a zone from that era of Battlefield 3 and 4 (because it takes place in the same timeline). But in returning to that area, we're now seeing what it was like once time has taken hold, and change has begun to form.
As this game takes place from 2042 onwards, what would it be like to go back to an area from 2020? What does it look like now?
Really glad that folks are liking what they are seeing then, the team really is putting some passion into this one. Already shows that we're working on Season 5 things, even as we approach launch of Season 4!
