Halo 5: Guardians is available for pre-orders for Xbox One with the release date set for October 27th, and there's a possibility that we may get to see Halo 5: Guardians make its way on the PC.
In a recent interview with Frank O'Connor, the director of the Halo 5 Guardians franchise, he was asked about the possibility of the game making an appearance on PC. He didn't deny the possibility but said that "there is plenty of chance that Halo 5 could appear on the PC." There's no official confirmation about its arrival but this should make things easier for Halo fans who are waiting for the game on other platforms. He did mention Windows 10 universal app experience, and said it won't be too difficult to port the game to PC as it was developed on an Intel platform.
Halo 5: Guardians franchise development director, Frank O’Connor said during an interview with Gamesradar (via Neowin),
“You know, Microsoft has made a huge commitment trying sort of… I think normalize the Windows experience across multiple platforms. You see the elements of Windows 10 are going to appear in Xbox and Cortana and stuff like that. There is plenty of chance that Halo 5 could appear on the PC. Nothing to announce at this point… you know, we developed the game on an Intel platform. It wouldn’t be the hardest thing in the world to move it to PC and take advantage of PC stuff. But nothing I announce today on this chat.”
There's no official confirmation from the folks over at 343 Industries about such possibility, but it would be interesting to see what they do. There are pros and cons of this decision, but let's see if it will launch on PC. We'll update you if any such thing happens.
