- Colonel: I hear it's amazing when the famous purple stuffed worm in flap-jaw space with the tuning fork does a raw blink on Hara-Kiri Rock. I need scissors! 61!
- Solid Snake: Find something to believe in, and find it for yourself. When you do, pass it on to the future.
- Raiden: Believe in what?
- Solid Snake: That's your problem.
- Solid Snake: Life isn't just about passing on your genes. We can leave behind much more than just DNA. Through speech, music, literature and movies... what we've seen, heard, felt... anger, joy and sorrow... these are the things I will pass on. That's what I live for. We need to pass the torch, and let our children read our messy and sad history by its light. We have all the magic of the digital age to do that with. The human race will probably come to an end some time, and new species may rule over this planet. Earth may not be forever, but we still have the responsibility to leave what traces of life we can. Building the future and keeping the past alive are one and the same thing.
- [When the player equips a cardboard box]
- Iroquois Pliskin: The cardboard box that you have is ideal for fooling your enemies. It's a very important tool for infiltration missions.
- Raiden: Really?
- Iroquois Pliskin: Of course. I can't begin to count the number of agents whose lives were saved by a cardboard box...
- Raiden: You mean everyone's using them?
- Iroquois Pliskin: Look, I'm not exaggerating when I say the success of your mission hinges on how you use that cardboard box. But in the end, a cardboard box is only made of paper. Handle it with care or it won't be of much use to you. Don't think of it as just another box. Treat it with love... Don't be rough. Okay?
- Solid Snake: We can tell other people about - having faith. What we had faith in. What we found important enough to fight for. It's not whether you were right or wrong, but how much faith you were willing to have, that decides the future.
- Colonel: Actually, I am in really bad shape financially. I pay money to my ex-wife as part of our divorce settlement, among other bills... I just had no choice but to make you pay for lunch the other day. I'm really sorry.
- Solidus Snake: Jack, listen to me. We're all born with an expiration date. No one lasts forever. Life is nothing but a grace period - for turning our genetic material into the next generation. The data of life is transferred from parent to child. That's how it works. But we have no heirs, no legacy. Cloned from our father, with the ability to reproduce conveniently engineered out. What is our legacy if we cannot pass the torch? Proof of our existence - a mark of some sort. When the torch is passed on from parent to child... it extends beyond DNA; information is imparted as well. All I want is to be remembered. By other people, by history.
- Solid Snake: If you run out of ammo, you can have mine.
- Raiden: You got enough?
- Solid Snake: [points to his bandanna] Absolutely. Infinite ammo.
- Otacon: Another Chinese proverb: "Those who look to the Heavens prosper, those who defy it are no more." Do you know this one? The meaning here is - hold on a sec - that you can only survive as long as you're a part of the natural order of things. You remember pre-ripped jeans? Manufacturers thought that just because people loved old, broken-in jeans, they would want to buy new jeans that looked old. So they purposefully...
- Solid Snake: What do jeans have to do with nature and order?
- Solid Snake: [reciting Grey Fox's last words] "We're not tools of the government, or anyone else. Fighting was the only thing I was good at, but at least I fought for what I believe in."
- Colonel: To begin with, we're not what you'd call "human." Over the past 200 years, a consciousness appeared layer by layer at the crucible of the White House. It's not unlike life started in the oceans four billion years ago. The White House was our primordial soup, a base of evolution. We are formless. We are the very discipline and morality that Americans invoke so often. How can anyone hope to eliminate us? As long as this nation exists, so will we.
- Raiden: Cut the crap! If you're immortal, why would you take away individual freedoms and censor the Net?
- Rose: Jack, don't be silly.
- Colonel: Don't you know that our plans have your interests - not ours - in mind?
- [Solid Snake hides in a locker]
- Solid Snake: This reminds me of when we first met.
- Otacon: I was the one inside the locker that time. We're equal now, huh?
- Solid Snake: Not unless I wet my pants.
- Otacon: That's a low blow, Snake.
- [Raiden loses all of his gear and is forced to sneak around in the nude]
- Colonel: Raiden, you won't be able to Hang, throw, or chokehold anyone in your current state.
- Raiden: Why not?
- Colonel: Is it really necessary to ask? It's just not a good idea to perform those maneuvers. There could be... complications.
- Rose: Oh really, Jack. Do we have to spell it out for you? Really!
- [Examining Emma's Policenauts poster]
- Raiden: What kind of a dork brings all this stuff to work? Must be a super freak!
- Pliskin: Fatman. Supposedly he's nicknamed after an atomic bomb, but to me he's just a Fat Man. Something straight out of a sideshow.
- Revolver Ocelot: Excellent speech my friend! Gift of the silver tongue. They say it's the mark of a good officer... and of a liar! Americans are too in love with the sound of their own voice to speak the truth!
- Otacon: What are you doing? How can you shoot someone who's unconscious? What are you, some kind of monster?
- Otacon: As for the equipment... Hey! Snake! Cigarettes? What's wrong with you?
- Solid Snake: It's kind of a lucky charm.
- Solidus Snake: The data of life is transferred from parent to child. That's how it works. But we have no heirs, no legacy. Cloned from our father, with the ability to reproduce conveniently engineered out. What is our legacy if we cannot pass the torch?
- Solid Snake: We don't use guns to take people down, and we're not here to help some politician either.
- Raiden: What are you and Otacon fighting for?
- Solid Snake: A future.
- Raiden: Snake, have you ever enjoyed killing someone?
- Solid Snake: Diminished sense of reality, huh? VR Training will do that.
- Olga: I grew up on the battlefield. Conflict and Victory were my parents. The unit is my Life, my Family. I have no one except the unit.
- Solid Snake: Freeze-dried, the rations are easy to carry and keep well. It ain't home cookin', but it'll satisfy your nutritional needs.
- Raiden: Hmmm.
- Solid Snake: What's on your mind?
- Raiden: Well, just between you and me?
- Solid Snake: Sure. What is it?
- Raiden: I prefer rations over Rose's home cooking...
- Solid Snake: That bad, huh?
- Liquid Snake: [to Solid Snake] The price of physical prodigy, two more years and you'll be another dead clone of the old man. Our raw materials are vintage, brother! Big Boss was in his late-fifties when they started making copies!
- Otacon: [Post-credits conversation] Snake, you there? It's me. I've finished going over that disc.
- Solid Snake: Did you find the Patriots' list?
- Otacon: Of course. It contains the personal data of twelve people. There was a name on it - Snake, it was one of our biggest contributors.
- Solid Snake: What's going on around here?
- Otacon: I don't know...
- Solid Snake: Anyway, where are they?
- Otacon: Well, we were right about them being on Manhattan, but...
- Solid Snake: But what?
- Otacon: They're already dead. All twelve of them.
- Solid Snake: When did it happen?
- Otacon: Well, ah... about a hundred years ago.
- Solid Snake: ...What the hell?
- Colonel: I was a North American Fall Webworm in my past life. Those were the good old days... What were you in your former life?
- [Vamp comes back to life in Fortune's arms]
- Vamp: There's no need for sorrow, Queen. I died once already. I can't die twice.
- [to Snake and Solidus]
- Liquid Snake: But before I go, I have a family matter to settle with both of you.
- Raiden: Snake, you're a legend!
- Solid Snake: A legend is usually bad news. Someone tells it, someone else remembers, everybody passes it on.
- Raiden: People will remember only the good part, the right part about what you did.
- Solid Snake: There's nothing right part in murder, not ever.
- Solidus Snake: Jack, those days during the civil war were as real as they come, split between life and death. You ran from it! And now you've been led back to war by something less than real.
- Raiden: All you want is power, at any cost.
- Solidus Snake: Jack, it's not power I want. What I want to take back from the Patriots are things like... freedom, civil rights, opportunities. The founding principles of this country. Everything that's about to be wiped out by their digital censorship.
- Solid Snake: This is Snake. Do you read me, Otacon?
- Otacon: Loud and clear, Snake.
- Solid Snake: Kept you waiting, huh? I'm at the sneak-point.
