Halo 5: Guardians Multiplayer Beta requires the Halo: The Master Chief Collection game disc.”
I THINK that bit is referring to halo: nightfall, so sorry to burst your bubble, but that really doesn’t look to me like they plan to give the halo 5 beta to PC.
Oh, I don’t really mind. I’m getting the Xbox One either way
