Sources are claiming the Halo: The Master Chief Collection will be making its way to PC with Windows 10, alongside Sunset Overdrive. This announcement is claimed to be occurring at the next big event for Microsoft — Gamescom.
Microsoft has already teased new announcements for Windows 10 and Xbox One when they revealed that their E3 line-up was "jam-packed." The tease was sidled alongside the announcement that Quantum Break, Scalebound, and Crackdown have been scheduled to appear at Gamescom, but the announcement had a tease specifically for new game reveals at Gamescom.
The individual who shared this information is known as MTW, who was apparently the same individual who leaked Halo 4 multiplayer footage prior to its release.
Sources for this rumor have not been revealed and the individual who was told does not feel "confident enough in it to say publicly" when the PC version of Halo: Master Chief Collection will release. If this rumor proves to be true, the Master Chief Collection will have Azure-powered user-controlled dedicated servers, 4K resolution support, will be controller only and "more."
Gamescom will be taking place on August 6 to 9, 2015.
