There are no loading screens, no lobbies, none of that traditional stuff. That means that while playing The Division, if you want to go do some pvp gaming, simply walk over to that part of the map to blast away. The coolest part of The Dark Zone is that it is right in the middle of Manhattan. This is the player versus player section of The Division.
So if there’s only one story quest, what else is there to do? The Dark Zone.
