We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
If you still need help you can either go to the marketplace and look up the game and you will find all the dlc, you can also go to the game from my games and then hit the x button to see game details then head to the extras section, Or you go to download
history from account settings on the dashboard.
