This maps is a duplicate of Evac that is a multiplayer map in Call of Duty: Black Ops 3. It functions an evacuation center which is centered on pinnacle of a huge complicated building. The complete structure is overgrown and looks very publish-apocalyptic. This is a ported map (and not using a shadow bugs) and you could use it for anything from hide and are seeking to a PvP war arena.
