Map??

map i played like last year forgot the name completeley have since deleted it and all screenshots but it was like old russian or east european place with really orange sky and setting all the buildings were in ruins and on each border of the map they had like a checkpoint with a tank btr maybe blocking the road, there was a school and all the buildings were walkable, and there was an underground sewer system you could crawl thru. Also a big square with a statue of lenin possibly? Could someone help me thanks
