Halo: The Master Chief Collection is expected to be coming to Windows 10 PCs. You will need the Windows 10 OS to access and play it. If that's a problem, then I suggest you dual-boot W10 to a seperate drive.
>How to play Halo with Yea Forums
1. Make sure you have the Windows 10 OS on your PC

the MCC contains every Halo campaign level, map, and game type from Halo 1, 2, 3, and 4. Also included is the ODST campaign. Halo Reach is rumored to be revealed alongside a PC port that will have cross-platform support. The reveal is expected today. The actual W10 version launch could be today or later in May.
