During the Metal Gear Solid V event at Gamescom today, Hideo Kojima confirmed that Metal Gear Solid V: Ground Zeroes and The Phantom Pain are coming to Steam.
The news followed a leak from the official Konami website which posted a headline and link to the announcement before quickly removing it.
The Steam pages for both The Phantom Pain and Ground Zeroes are now live, and while neither mention a release date, Kojima has confirmed that Ground Zeroes will be released first followed by The Phantom Pain.
