It looks like PC players are going to have to wait a little bit longer for their taste of Metal Gear Solid V than console players will. While the console version will launch on September 1, the PC version was recently confirmed by Konami UK to be launching on September 15. No reason was given for this delay.
That being said, the PC is still shaping up to be the “console” of choice this year, if you are OK with waiting a little bit for your releases. It has gotten every console exclusive release with the exception of a few Nippon Ichi and Atlus games so far.
