It’s been the desire of a lot of PC gamers to have Halo, one of the most popular first-person shooter franchises in history, on the PC. Halo 2 Vista and Halo: Combat Evolved were both the last games in the series that were put on PC, but now, according to Kotaku (based on their soruce), all new Halo games will also be ported to Windows 10 PCs in addition to being released on the Xbox One.
This is only a short time after Microsoft announced that Halo 5’s Forge would now be available to use on the PC.
The porting of new Halo games or existing ones to the PC has already been implied before, months ago, back when Halo 5: Guardians first launched.
Halo 2 Vista, as the PC version of Halo 2 was known, was released in 2006 for much the same reason as this decision likely is: to push sales of Windows 10. It could also be made to run on Windows XP through a third-party unlicensed patch.
The game was originally ported to Windows Vista by a small team at Microsoft that worked closely with Bungie, while Halo was still under their ownership. This Windows port also added two exclusive multiplayer maps, called District and Uplift.
Halo: Combat Evolved for the PC was released in 2003 on Mac OS and Windows, and had a number of other exclusive editions added such as the Rocket Hog and other multiplayer maps.
However, many more new Halo games there are going to be remains to be seen, considering that Halo 5: Guardians is the second in a newly planned trilogy. Thus the plot with Cortana and her new Created faction will most likely be wrapping up in Halo 6, unless a new trilogy comes out.
The addition of new Halo games to the PC is part of a concentrated effort for Microsoft to begin putting out new and existing IPs onto both Xbox One and PC in order to increase the sales of both.
This began (with a rocky start) with Quantum Break, which was originally announced to be an Xbox One exclusive before it was also announced to be on Windows PC, which caused a great deal of division among Microsoft fans.
