We knew it was coming, we've been able to get it pre-loaded, but now it's finally time. The Halo 5: Guardians multiplayer beta is now live for every single owner of the Halo: Master Chief Collection on Xbox One. You only get a couple of weeks to play it, so make the most of it while you can.
We'll be back with a first look soon, but what are you waiting for? Go get it!
