11 Facts You Never Knew About The Development Of Metal Gear Solid

5. The Developers Literally Haunt The Code Of The Original Game

There's plenty of reasons to revisit the original Metal Gear Solid; from infinite ammo to an invisible sneaking suit, the game's sheer amount of secrets means that every single play-through can be tackled in surprisingly different ways. However, perhaps the most compelling reason to boot up the original after all these years is to hunt down the 42 ghosts that haunt the corridors of the original game. If you're lucky enough to snap the right locations with the camera you'll be treated to haunting images of the title's developers scattered around Shadow Moses, with Kojima himself providing a particularly creepy image right next to a poster of Policenauts.
