Character: "Solid Snake" / "Old Snake" / David
Chapter 1: Liquid Sun Part 5
The reunion was short, but there are party crashers that needs some wiping out, so Snake, Meryl & her team including the stomachache guy, Akiba, had to fight their way out. This is really the game that reunites all characters in the whole MGS series.
