On Xbox I Have Modern Warfare 2 but I got the cross gen edition a couple weeks ago how can...

There is a message on the store in the Vault Edition that says: "Existing Modern Warfare 2 digital Cross Gen Bundle can upgrade to the Vault Edition as a part of a limited time offer"

But I don't see anywhere in the store the update or any instructions regarding how that works.

Hello, welcome to Microsoft Answers Community.

Yes. You will need a Microsoft Account to download games from Microsoft Store or Xbox, and play them in Online mode.

However, neither the Vault Edition nor the Cross-Gen Bundle of Call of Duty®: Modern Warfare® II is included with Xbox Game Pass. Therefore, you do not need an XGP membership.

*For Call of Duty®: Modern Warfare® II - Vault Edition, please visit Buy Call of Duty®: Modern Warfare® II - Vault Edition | Xbox;
*For Call of Duty®: Modern Warfare® II - Cross-Gen Bundle, please visit Buy Call of Duty®: Modern Warfare® II - Cross-Gen Bundle | Xbox

*For the official page of Call od Duty: Modern Warfare II, please visit https://www.xbox.com/en-US/games/call-of-duty-modern-warfare-ii.

Hi, I found that strange… what edition was the one that you purchased?
Vault or Cross-gen?

In the meantime tell me, if you go here and sign in with the account that owns the game. Are you able to see an “install” button? Or just “buy”?

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Cole

I'm starting to see some reports from other players about this.
It seems that right now there is a bug with this upgrade to vault edition option offered to the cross gen bundle players (the system ask to pay the full game instead of the $30 difference)

Please report this problem to both Activision and Xbox
Hopefully a fix is going to be released as soon as possible
