Snake: Big Boss... you're alive?!
Big Boss: Snake... Welcome to Zanzibar Land... I knew you'd come back to me.
Snake: I came to get rid of the nightmares I've been having for the past three years.
Big Boss: The nightmares? They never go away, Snake. Once you've been on the battlefield, tasted the exhilaration, the tension... it all becomes part of you. Once you've awakened the warrior within... it never sleeps again. You crave even bigger tensions, ever bigger thrills. As a mercenary, I'd think you would have realized that by now. You care nothing for power, or money, or even sex. The only thing that satisfies your cravings... is WAR! All I've done is give you a place for it. I've given you a reason to live.
Snake: I would never have made you for such a hypocrite, Big Boss...
Big Boss: You saw those children, didn't you? Every one is a victim of a war somewhere of the world. And they'll make fine soldiers in the next war. Start a war, for its flames, create victims... Then save them, train them... And feed them back onto the battlefield. It's a perfectly logical system. In this world of ours, conflict never ends. And neither does our purpose... our raison d'etre.
Snake: So there's plenty of job opportunities... Is that what you're trying to say?
Big Boss: On the battlefield, you and I are valuable commodities. But back "home", we're nothing but dead weight. If we're lucky, we might get the attention of some two-bit journalist from a cheap tabloid. You and I are doomed to remain here until we die like dogs on the battlefield.
Snake: ...I've only got one fight left. To free myself from your grip, to rid myself of these nightmares... Big Boss, I will defeat you!
Big Boss: It doesn't matter who wins here. Our fight will continue. The loser will be liberated from the battlefield, and the survivor will live out the rest of his days as a soldier.
Snake: It doesn't have to be that way. I'm not like you. I love life!
Big Boss: Very well, Snake. I'll release you from your suffering. As your former commander, I'll do you one last favor... and put you out of your misery.
Snake: I don't need any more favors from you!
Big Boss: Really?... And just how do you expect to beat me in your condition? With no weapon?
Snake: Never give up. Fight until the end. Always believe you will succeed, even when the odds are against you. ...Those are your words.
Big Boss: Even I make mistakes from time to time. Snake! This will be our final battle... Let's end this once and for all!
