The player character smokes cigars, and can equip them during the game in the secondary slot. When equipped, the Cigar will gradually drain the player's health, and the smell of the smoke will potentially alert guards to your presence. However, the cigar can be used to illuminate dark places, drive away wasps and hornets, and burn off leeches in the SURVIVAL VIEWER. Aside from this, there are samples of experimental "Life Medicine" throughout the game, acting as the stand-in for Rations (since Rations now restore Stamina instead of Health). When consumed, this medicinal serum instantly restores the player's health a significant amount. Finally, there are the Fake Death and Revival pills. (Re: "Does someone die by suicide?")
During one of the cutscenes where Snake has disguised himself as Major Raikov, Volgin enters Sokolov's cell where Snake had been talking to him and manages to work out that 'Raikov' is someone in disguise by suddenly grabbing Snake's crotch to see how he reacts - Snake pushes his hand away. It probably isn't intended to be a joke and rather a shocking moment that reveals the relationship between Raikov and Volgin, but the suddenness of the crotch grab might unintentionally feel like a joke to some people.
The player has the option to slit an enemy’s throat while choke holding them. Later in the game the people who’s throats you slit come back as ghosts and scream about the pain of having their neck open
Using the CQC melee system, you can put enemy soldiers into a choke-hold, and choke them out to knock them unconscious and potentially snap their necks by choking them out too fast.
TECHNICALLY... there’s a part of the game where you’re confronted with the specters of everyone you’ve killed, and if you kill an enemy, who then gets eaten by a vulture, then you kill that vulture and eat it, that enemy will be in this sequence, and will point his finger at you and say “You ATE me!” But that hardly counts, right? I just know too much about this game!
Some of the Cobra Unit members veer into this: The Pain gets covered in hornets constantly and the few bits of his face we can see are either covered in sting-related bumps or represent cave parts of a nest, The Fear has a long tongue and can bend his arms backward in order to move and climb trees, The End can bulge an eye to have better view on his scope and The Fury is implied to be covered in third degree burns.
Basically no. If the player deals a killing blow to an enemy's crotch then it will be implied when their ghost shows up later. It's not likely to happen unintentionally.
You are guaranteed to suffer at least one broken bone at the end of the first act for the SURVIVAL VIEWER tutorial, and a second broken bone during the game's torture sequence. Depending on what you do over the course of your adventure you can end up breaking more.
The main character is taken prisoner.
Towards the end of the game there's mention of a character's newborn being taken away from her for government training purposes.
In the sequence where the supporting character The Sorrow shows you the total kills you have caused in your campaign up to that point, he will occasionally throw energy projectiles which result in a bright flash and a loud scream if hit.
Snake is thrown into a jail cell after being tortured, but this can quickly be escaped by tuning the radio to the frequency shown in the previous cutscene.
You can find multiple items called Life Medicine which is shown as a liquid in a syringe. It doesn't show any usage but there are the obvious implications.
The player is given a number of Fake Death Pills at the start of the mission, accessible from the secondary slot. When consumed, the character will enter into a comatose state and bringing up the game over screen. During this game over screen, the player can open the secondary slot menu again to consume a revival pill lodged in the character's tooth, but it must be consumed before the game over text fully transitions into "TIME PARADOX", at which point the player character is truly dead and will have to continue or load a previous save.
Every major boss character aside from Volgin and Ocelot has a bomb planted inside of them that triggers once they're defeated; this is explained in-game to prevent them from being captured.
While not a suicide, the Player Character euthanizes the final boss, after she requests him to do so to complete his mission.
In the 2006 special edition Subsistence, there is a secret "Blooper" Cutscene based on the moment where the final boss betrays the player character from the end of the first act. Instead of the swarm of bees attacking the player, they attack the final boss, who jumps off the bridge causing her bomb to explode.
More emphasised in the HD version due to being uncompressed, the villain's lightning bolts can cause this effect.
One of the cutscenes in the 2006 release's Secret Theatre also begins with rapidly flashing lights.
Mention is made of a traumatic cesarean section that one character underwent - a scar from this is shown, but the incident itself took place long before the game itself
There’s a camouflage Snake uses to paint his face completely black but this is purely used as a military tactic disguise to blend into dark areas to avoid detection by enemy soldiers. It’s not used as or even remotely comes across as Snake imitating a black person.
