Suggested MPAA Rating: "PG-13" for Prolonged Sequences of War-Related Action and Violence including Intense Sustained Gunfights and Explosives, and for Disturbing Moments and Some Bloody Images, Brief Strong Language, Innuendo, and Scenes of Crude Humor.
Like all the Metal Gear Solid games, the story is intense and features frightening, disturbing and violent characters.
The games atmosphere is dark and it's philosophical nature make this a game for 16 years and over.
Some of the shoot-outs are intense.
As well as the B&B boss cut-scenes.
The backstories of the B&B members may be disturbing to some. Namely:
Laughing Octopus: Her entire Scandinavian town was executed by an anonymous cult, and she was forced by the same cult to brutally massacre her family and friends, as well as to enjoy having to kill them by laughing.
Raging Raven: She was placed in a cage with other children by soldiers (presumably from Indonesia), and was regularly beaten to a pulp by the soldiers in their fury, and was later left to die. She was later left with the kids to become snacks for Ravens, but before they could feast on her, she tore them apart, and later tracked the soldiers down and at nightfall started killing the soldiers, even going as far as to kill the civilians that they captured, all the while cawing and screaming in an uncontrollable rage
Crying Wolf: Her family and friends were slaughtered by a faction in Africa due to ethnic cleansing, and left her and her baby brother the sole survivors, as well as refugees. she later accidentally smothers her baby brother to death when trying to keep him from crying and alerting soldiers to their presence. Afterwards, feeling immense guilt, she later hallucinates a wolf following beside her, and after getting to a government run camp, she starts being disturbed by the cries of children, and later starts believing that a wolf is killing the children (in reality, she was the one killing them).
Screaming Mantis:Probably the most disturbing backstory. After her home village was burned to the ground in a war, she ended up being separated from her family, and was being pursued by Death Squads in South America. She tried hiding inside the basement of a building, but soon discovers that the building was actually a homemade torture chamber, complete with corpses littered around the basement. She couldn't just leave due to the military presence of the building, and she later can't even leave the basement due to it being locked up. Because of this, she ends up being traumatized by the screams of tortured villagers day and night. She later began to hallucinate after drinking contaminated water, hallucinating of a Black Praying Mantis that taught her how to block her ears and then eat the male corpses, essentially commiting cannibalism to survive the weeks locked up in the building.
Snake, during the ending, attempts to commit suicide by placing a gun in his mouth and firing it, but is later revealed to have evaded the option at the last second. The idea of suicide may be distressing to some players
Major Zero and Big Boss's deaths maybe upsetting. Big Boss kills Zero by cutting off his life support, and then dies due to the effect of FOXDIE within Snake.
