The latest update for Overwatch is out on the PlayStation 4 and it includes a new escort map called Junkertown. This new map is associated with the Junkers, Junkrat and Roadhog, who recently both received an animated short and a comic detailing parts of their history at Junkertown.
The update also brings with it some major changes for both D. Va and Mercy. D. Va has been given a whole new ability called Micro Missiles, allowing her to blast away foes with ease, while Mercy has had a complete overhaul, with a redesign of the majority of her kit. You can check out all of the changes through here.
