History NightmareFuel / MetalGearSolid3SnakeEater

* The very concept of the dense forest setting can be very unnerving for players, especially on higher difficulty with more aggressive AI and less supplies. You're crawling through the foliage, low on medical supplies, trying to avoid getting seen by some enemies just up ahead... when suddenly something starts beeping, and you realise it's your health, because something just bit you. Could be a snake, or a spider, or mabye a scorpion stung you. Either way, chances of finding it now are slim since it's probably scuttled / slithered / crawled away. Bottom line, you're going to die unless you scrape together enough supplies to fix it.

** The [[UncannyValley creepy and unnatural]] way the bosses move as well. The End even appears to still be (mostly) comatose, even in death.

** The one characteristic potentially dampening the horror of the Shagohod is its slow, ponderous movement. As long as you can put some distance between it and yourself, you should be in the clear, right? Cue the ‘’rocket engines!’’

* Snake Eater has what is the most unsettling GameOver screen in the series. Beyond the standard anguished screams of your allies ([[NightmareRetardant or Colonel Campbell deriding you for causing a time paradox if Ocelot or EVA dies]]), this screen's unsettling aspects come into play if you do nothing for a while. The words SNAKE/OCELOT/EVA IS DEAD slowly morph into TIME PARADOX while [[https://www.youtube.com/watch?v=EsmQdAdOzZY this chilling track]] plays in the background. Should the sentence fully transform (or if the Exit option is selected, which speeds up the process), there's a LastNoteNightmare followed by a gunshot, and then the colors invert, just for one final scare. No other Metal Gear title has a GameOver screen like this, which makes it all the more frightening.

** It gets to the point where Big Boss pisses himself from the electrical surges going through his body. Volgin is aroused by it... ''and so is Ocelot''. By this point, he's so obsessively attracted to Snake that seeing Snake being tortured is not only an arousing experience for him, but it makes him have an epiphany that torture is "the ultimate form of expression," and it leads to him becoming a world-renowned expert on the subject. The way in which he describes this viewpoint to Snake is incredibly unsettling, seeing as how his arrogance and his feelings for Snake had largely been played for comedy up to this point.

** While it's only referenced in a single conversation and has no in-game relevance, Snake returning to the field after a mere week would have put ''immense'' strain on his body, as Paramedic states. At a minimum, he suffered a dislocated elbow and two bone fractures, plus various deep cuts, during the Virtuous Mission. Bone fractures can take ''years'' to heal, and even then there's no guarantee they will regain their original functionality, not to mention the lasting effects of a dislocation (inflamed tendons) rendering his left arm compromised. Then there's what his already-weakened body [[ColdBloodedTorture is subjected to later.]]

** While it's only referenced in a single conversation and has no in-game relevance, Snake by all accounts ''should still have been in hospital'' instead of being dispatched for another mission. At a minimum, he suffered a dislocated elbow and two bone fractures, plus various deep cuts, during the Virtuous Mission. Bone fractures can potentially take ''years'' to heal, and even then there's no guarantee they will regain 100% function.
