Over the weekend, Xbox One Preview Members were treated to a sneak peek of Halo 5: Guardians' upcoming multiplayer beta. The two-day Early Access period offered members one game mode, Slayer, on two different maps, Empire and Truth. It gave players a chance to go hands-on with the changes incoming with Halo 5, but more importantly it gave 343 Industries a chance to receive feedback. And apparently, more previews like the one offered with Halo 5: Guardians are on the way, according to Xbox Head Phil Spencer.
