"'Ground Zeroes' is a prologue of MGSV," Kojima said. "9 years after that event will be 'The Phantom Pain.'" Metal Gear Solid 5 comprises these two parts, much like Metal Gear Solid 2 opened with the Tanker chapter, then moved onto the Plant portion starring Raiden. "The game play demo I presented today is the opening of [The Phantom Pain] which is tutorial that starts from crawling." [Update: Contrary to what Kojima said during the GDC panel today, Konami has confirmed with Joystiq that Metal Gear Solid: Ground Zeroes and Metal Gear Solid V: The Phantom Pain are indeed separate games.]
Wow, what is this feeling? Is it ... understanding a Metal Gear game?
