Konami has finally acknowledged the possibility of Metal Gear Solid 4 being part of an expected Metal Gear Solid: Master Collection Vol. 2.
Last year, the company released Master Collection Vol. 1, which includes the first three Metal Gear Solid games plus some extra classics.
However, a second volume is widely expected to continue the story with Metal Gear Solid 4, 5, and Peace Walker, with fans digging around on the Konami website and the first volume’s game files for details.
