Konami has revealed that sales of the Metal Gear franchise have managed to exceed 31 million, as of the 31st of December, 2011. This means that the figures exclude the recent Metal Gear Solid HD Collection.
Metal Gear Solid: Snake Eater 3D also just launched on the Nintendo 3DS, offering gamers the chance to play some Metal Gear Solid 3 on the go, with some nice 3D visuals..
Metal Gear, the game which started it all, appeared back in 1987 and offered similar gameplay to what we see today. It appeared first on the MSX2, followed by a release on the NES later that year in Japan.
Confusion then cropped up, as two games were made to follow this up. Snake's Revenge and Metal Gear 2: Solid Snake. Only the second was created by Hideo Kojima, with Snake's Revenge being developed specifically for the Western audiences.
The franchise hit the big time with the release of Metal Gear Solid on the PlayStation One, which paved the way for Metal Gear Solid 2: Sons of Liberty, to earn the plaudits when it released on the PlayStation 2.
