GodisaGeek: "It’s very rare for any franchise to wave farewell to it’s protagonist. This is true of all forms of media. It takes a creator with balls to pull the trigger, to draw a line and say, “That’s the end of that”. As of now, Hideo Kojima has done just that, with Solid Snake’s fate left open-ended in Metal Gear Solid 4: Guns of The Patriots.
Of course, this is the same videogame auteur who maintained for most of the series that he’d never do a new one (only to do just that, several times over). The very same person who, in many promotional trailers for Guns of The Patriots, showed an old, fatigued Snake contemplate the merits of inserting the barrel of his gun into his opened mouth, with the threat of pulling the trigger. While this scene doesn’t take place in the exact same way in the final game, this is one of many hints that this is the final chapter in Solid Snake’s story – or even in his life."
