Metal Gear Solid V: The Phantom Pain is a 2015 action-adventure stealth video game developed by Kojima Productions and published by Konami. Directed, written, and designed by Hideo Kojima, it is the ninth installment in the Metal Gear franchise, following Metal Gear Solid V: Ground Zeroes, a stand-alone prologue released the previous year. Set in 1984, nine years after the events of Ground Zeroes, the story follows mercenary leader Punished "Venom" Snake as he ventures into Soviet-occupied Afghanistan and the Angola–Zaire border region to exact revenge on those who destroyed his forces and came close to killing him during the climax of Ground Zeroes.

A stealth game is a type of video game in which the player primarily uses stealth to avoid or overcome opponents. Games in the genre typically allow the player to remain undetected by hiding, sneaking, or using disguises. Some games allow the player to choose between a stealthy approach or directly attacking antagonists, but rewarding the player for greater use of stealth. The genre has employed espionage, counter-terrorism, and rogue themes, with protagonists that are special forces operatives, special agents, secret agents, thieves, ninjas, or assassins. Some games have also combined stealth elements with other genres, such as first-person shooters and also platformers.
