Naw, it'll be Metal Gear Gear!
Snake's brain has been implanted into a Metal Gear stage 1 robot. He'll have to destroy every instance of a Metal Gear, and plans for one.
Just as we near the end we see Liquid snake holding a mirror. He tells us what he's done and that to truly kill every Metal Gear, we must destroy ourselves....
The end has Snake debating on whether or not to sink the ship he's on, thus killing him and everyone that he hasn't already killed.
In the end he gets to the deck and fires two rockets into the hull as we escape uninjured for the millionth bloody time....
Kojima will dub it a master-piece and everyone who's played it will call it utter shite!
I figured to get the full picture of how the series has been done to death, you have to see the FULL picture.
