No specific date was given at Sony’s press conference this evening at E3 2017, but we did get a trailer for the surprise announcement. Many thought that the title would not receive any DLC- something a lot of players were content with- but The Frozen Wildlands looks like it could add a decent amount to the already vast open-world of the popular game. We will provide more information on the DLC as it is released, hopefully this week before E3 is over.
