For the third time, legendary agent Solid Snake destroyed the walking tank Metal Gear deep behind enemy lines and saved the world from Armageddon, this time from his old unit FOX-HOUND led by his newly-revealed twin brother Liquid Snake. Until then, Metal Gear Solid had been an action-packed bonanza told through expertly produced cinematics that rivaled Hollywood blockbusters. And then the story pivoted at its climax. What had been a politically charged narrative about terrorism and the threat of nuclear war changed into an examination on genetics, using the very technology and rendering techniques that brought the game to life to reinforce its deep and complex themes. With MGS, Hideo Kojima merged his narrative and gameplay abilities into a deep metaphor about biology, technology, and destiny.
