Moments: Gray Fox's Hallway
The first Metal Gear Solid is responsible for far more than one memorable gaming moment. Tricking guards by sitting in a cardboard box. Silently snapping a neck as you sneak to your next objective. Switching your controller port to confuse Psycho Mantis. Hideo Kojima's 1998 classic is remembered by many as the first game that featured production values and cinematics that put it on par with a Hollywood movie. One point in the game did a fantastic job of simultaneously filling the player with dread and making them wonder what was coming up next.
By the time you enter the hallway prior to the Gray Fox fight, you've briefly encountered him after your battle with Revolver Ocelot. Stepping into the hall, Solid Snake sees several bloodied bodies strewn about on the floor. The level of violence on display isn't consistent with bullet wounds, so the cyborg ninja is the obvious culprit. While the Twin Snakes remake (seen above) shows the actual massacre, the PSone original leaves it to the player's imagination. Something terrible happened here, and odds are, you're going to have to face it head-on.
Snake makes his way down the hall, and a bleeding guard crawls around the corner saying "It's...a ghost!". The camera pans around to reveal a body being suspended in mid-air by some unknown force. Turning off his optic camouflage, Gray Fox reveals himself as he holds the body up on the blade of his sword. He walks into the next room, and the player knows he's in for a fight.
Take a look at the scene below, starting at 5:35.
