It can get pretty frustrating when you’re fully immersed in a game like Black Ops Cold War and your controller gives out on you. Users are complaining on Reddit and yes, a bug that should have been fixed back in the beta is still crippling gameplay before players can even reach Mission 3 (Fracture Jaw).
HOW TO FIX THE COLD WAR PS4 CONTROLLER BUG
If your PS4 controller becomes loose and the R2 button no longer works during Mission 3, you're not alone.
Be careful, this bug can break your HD. I tried reloading Fractured Jaw 2 more times and it disconnects your controllers and blocks your R2 button. Then you have to hard power down and reboot and get a HD error. It happens to a lot of us, sounds like blackopscoldwar
