Here's how to link and merge accounts to enable cross-progression in MW2 & Warzone 2.
To enable cross-progression in Modern Warfare 2 & Warzone 2, players will have to link and merge their gaming account with their Activision profile. By doing this you won’t have to replay the game when you start on a new console/PC, and you can continue using your favorite weapons, attachments, and more in MW2 or Warzone 2.0. If you are not sure how to do it, this guide will come to the rescue. Here’s how to merge accounts in MW2 for PS4, PS5, Xbox, and PC users.
You may need to do this if you linked your Activision account to the wrong Battle.net account. Do keep in mind that games that have cross-progression will store the game progress on your Activision account and not your platform account. This is how the progress and content will carry over.
Another important thing to note is that you may unlink individual platform accounts from an Activision account once every 12 months. So do it wisely.
