Microsoft announced during their E3 2014 conference that the Halo: Master Chief Collection would include access to the Halo 5: Guardians multiplayer beta and now the exact date has been revealed. Owners of the collection will be able to start playing the Halo 5: Guardians beta on December 27th of this year. It is scheduled to end on January 22nd, 2015. 343 also did say that these start and end dates aren’t final, so don’t obsess over them quite yet. Also, the Halo: Master Chief Collection disc will be required to play the beta, so it won’t be code access.
The Halo: Master Chief Collection will be available on November 11th, 2014 exclusively on the Xbox One.
