  • Exactly the same problem as Danny above on PS4!!

    I have done 2 deletes and installs and same problem still!
    This is not accetable for a game thats costs £100 at launch with addons, we expect some bugs but not ones that completely stop you playing and losing weapons and items you have collected or XP and weapon XP you have earned.


    Happy New Year.
