Later today, the teams will be opening up the Titanfall Beta to all Xbox One owners. That means no code will be necessary to download and play the beta. We are really excited to get a good test on all of our systems before launch and encourage you to join in.
To download the beta, sign in to your Xbox One and head to the “New Game Demos” section of the Game Store and it will appear there. You can also say “Xbox Bing” then “Show me game demos”.
Note: It may take some time until all Xbox One’s can see the demo in the store. Some members may see it before others. Until then just relax and rest assured everyone will see it soon.
While you are waiting for it to appear on your console, here is some suggested reading to prepare you for battle:
