Activision’s Call of Duty: Black Ops Cold War seems to have some interesting ‘features’ that were never listed. It’s disconnect PS4 Dualshock controllers mid game, and some people can’t even download the PlayStation 5 version, it just gets stuck in their queue and/or downloads the PlayStation 4 version instead.
Let’s start with the PS5 download bug which unfortunately has one fix at the moment and you’re not going to like it. You need to do a full factory reset of the console, which will wipe any games and updates you have installed.
To perform a factory reset of your PlayStation 5, you must navigate to the gear icon on the top right of the home screen which takes you to the System Settings page. From there head to the System section, , select Reset Options and then Reset Your Console. At this point you will need to confirm you are going to wipe everything from your console.
As this is such a huge bug Activision should be fixing it very quickly so you may want to wait a day or two rather than have to reinstall all your PS5 games.
Moving on to PlayStation 4 players who have been reporting that the Dualshock controller starts flashing and disconnects. This seems to happen at the start of the third mission in the campaign but there are also reports of the fault occurring during multiplayer and zombies matches. There is a fix, but once again it’s not a good one, you need to hook the controller up to the console with a USB cable and play with it connected rather than wirelessly.
Insert the cable in to your controller, connect it to the PS4, then got to Settings > Devices > Controllers and from that menu choose Communication Method and change it to “Use USB Cable”. That should sort you out, again it’s a rather huge bug so hopefully Treyarch are on the case and will issue a fix soon.
