Microsoft has confirmed the dates for the Halo 5: Guardians beta.
It will take place between Dec 29th and Jan 18th, and will be available to those who buy Halo: The Master Chief Collection on Xbox One.
The beta will focus on 4v4 combat in small arenas and will, according to developer 343, run at 60 frames per second on dedicated servers.
Some elements of the progress will be carried over into Halo 5: Guardians and there will be lots of dedicated programming on The Halo Channel.
