Yes I know what you’re thinking, Metal Gear Solid?? EVERYONE KNOWS ABOUT THAT GAME.
But I’m not referring to the Playstation game at all.
No what I’m referring to is the Gameboy color game.
In Japan it was released under the title Metal Gear: Ghost Babel. The story is not continuous with any of the Metal Gear Solid story lines, but it is an alternate timeline that takes place 8 years after the events of Outer Heaven.
