According to GameBlog.fr, there is possibly more to the ending for Metal Gear Solid 4. Rumor has it that six months after leaving the game, something will trigger in the game and spawn a “last minute surprise.”
This sounds like an awesome idea, but is it really possible? I know that technology is advanced and we can probably guess that the PS3 would be able to tell six months after you beat the game, but.. could it really? =/ This is a rumor that would be cool if it was true, but I have a strong feeling that it is just that. A rumor.
