Should have been named MGSV: Retcon everything. So yeah, the game's story is awful. Kojima really went out of his way to show how awful he is at storytelling. Language killing parasites? And the story's twist? All garbage. Skull face was a waste. Mother Base a waste, everything was just a waste. Except the gameplay, which was the only redeeming factor for this game. Even then, it's not perfect, with iffy hit boxes, poor mission system, and tons of repetition and grinding. But man, that stealth gameplay is fantastic.
