This morning at Gamescom, Microsoft and 343 Industries talked a little about the multiplayer beta for Halo 5: Guardians. The beta will run from December 29th to January 18th.
343 Industries said that having a beta this early in development is “crucial,” since it allows the development team to react to feedback from players. The beta will focus on 4-on-4 arena matches and will run at 60 frames-per-second.
The Halo 5: Guardians multiplayer beta will come with Halo: The Master Chief Collection, which will be released for Xbox One on November 11th, 2014.
