Gameplayer has gone live with a detailed look at the convoluted narrative of the Metal Gear Solid series, followed by an analysis of the new features coming the fourth and final game in the series.
"Series creator Hideo Kojima has stated on a number of occasions that it will be the last Metal Gear Solid game. He's also said it will be his last Metal Gear Solid game (a subtle distinction, but important nonetheless). Then again, he said MGS3 would be his last, so maybe he just likes toying with the fans. Either way, it seems that MGS4 will be Solid Snake's last appearance; to explain why, a little Metal Gear history may be needed."
