The Halo Infinite beta (or technical test) is live now and running this weekend, giving you the chance to try out the game's new weapons and systems if you happened to get an invitation. However, the process for playing doesn't end with getting an invitation. You also have to install the Halo Infinite beta client, and that varies depending on where you're playing the game. Here's how to do it and get playing. Were it so easy? It's not that easy, but you can install it fairly quickly by following these steps.
From here, you should see a "Manage" prompt, after which you'll need to go through some terms and conditions before you can install the beta build. Once it's installed, you'll be able to access and run it just like you would any other game via the My Games & Apps section of the Xbox UI.
Start the game and when prompted, make sure you use the same Xbox Live account you used when you registered for the beta. Once that's done, you're ready to play.
Halo Infinite will release this holiday season for Xbox One, Xbox Series X|S, and PC. It features new accessibility settings that should make it easier to play for those with colorblindness.
