The Phantom Pain is a game rife with politics and dystopia. For starters, you play as Big Boss, a legendary soldier turned leader of the mercenary outfit Militaires Sans Frontieres (Military Without Borders). You and your men are willing to fight for anyone and anything, as long as the price is right.
The game has a number of controversial topics within it such as child soldiers, blood diamonds, nuclear armament, and unethical human testing. There is also a number of flashbacks to moments of extreme violence from Big Boss' past that breach the topic of PTSD in those who experience the harsh realities of war.
