I keep getting error code Hueneme discord on mw2 I can't even play the game I paid for.

Please try reinstalling the game from your library or remotely from here:

Standard: https://www.xbox.com/games/store/call-of-duty-m...

The game appears in your Microsoft account order history with status completed?

Also, just to confirm. If you played the beta in the past. Make sure that you are opening the base game and not the beta.
If you're not sure about this please try deleting the game(s) and install it from your library or remotely from here:

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 Noah

As a friendly reminder, Microsoft is not the developer. It's Activision.
Now, going back to the main topic and just to confirm, the game appears in your Microsoft account order history with status completed?

If yes, this can be a bit odd, but please try this in your console:

go to Settings > Network > Advanced Settings

Once you’re inside the Advanced Settings menu, go to DNS settings and select Manual from the list of available options.
When you get to the next screen, enter 8.8.8.8 in the box associated with the Primary DNS and 8.8.4.4 in the Secondary DNS box.

Once the default DNS addresses have been changed, restart your console and see if the issue has been resolved at the next console startup.

If that doesn't work use 1.1.1.1 as primary and 1.0.0.1 as secondary

It's actually ridiculous! I've been getting the error code for so long now and paid good money for a game I can't even play.

But I can't buy it at all, even for the full price. I just keep getting the error code.
