Sign in gamer tag is changed when I open Call of duty warzone

Go into the COD Warzone Settings - Account section and see if you have enabled using Activision account. The Activision account can use a name that is totally different than your XBL account. I've never used that myself so I don't know if it's possible to turn it off again after enabling it the first time.

Good luck!

basically go to your cod account via the website and login, you can change your name to whatever you want inclusing your live name, you can change it upto 5 times per year.

I'm sorry, but this is thee Most misleading piece of advertising I have ever seen.

On the Store is clearly states

Call of Duty: Warzone

Includes:

Call of Duty: Modern Warfare II

Call of Duty: Modern Warfare II - Content Pack 4

When you download it requires campaign download. When you load up Warzone it takes you to an additional download page for Warzone and Modern Warfare II. Yet still requires you to pay.

Sorry but this needs correcting, at no point, anywhere does it state that all you get is Warzone. Why add, includes Call of Duty: Modern Warfare II if it doesn't. You need to either change this description to Call of Duty: Modern Warfare II - Warzone or your clearly in breach of false advertising.

Regards

Call of Duty: Warzone is coming to Xbox tomorrow

Hello,

This looks like it may be occurring in the game-and if it only occurring with Call of Duty, I am led to believe that it may be an in-game issue. Can you confirm if this is an error being given to you by the game itself or is this an error being given to you by the console.

For Call of Duty support:

• Call of Duty: Warzone | Activision Support
  
• Connecting to a Call of Duty Warzone Game
  
• Support Options | Activision Support
  

Thank you,
