"War... has changed. It's no longer about nations, ideologies, or ethnicity. It's an endless series of proxy battles fought by mercenaries and machines. War, and its consumption of life, has become a well-oiled machine. War has changed. ID-tagged soldiers carry ID-tagged weapons, use ID-tagged gear. Nano-machines inside their bodies enhance and regulate their abilities. Genetic control, information control, emotion control... battlefield control. Everything is monitored and kept under control. War - has changed. The age of deterrence has become the age of control. All in the name of averting catastrophe from Weapons of Mass Destruction. And he who controls the battlefield, controls history. War has changed... When the battlefield is under total control, war becomes routine."

Meryl Silverburgh: So, what do you think? Is your age of heroes finally over?
"Old" Snake: ... Huh. I'm no hero. Never was. Never will be... I'm just an old killer, hired to do some wet work.
Vamp: You too... Immortal?
Raiden: No... I just don't fear death.
Snake: Liquid, you're planning to recreate the Patriots?
Liquid Ocelot: Snake, we were created by the Patriots. We're not men. We're shadows in the shape of men. We're freaks who never should have existed! We're a system... insurance that future generations never prosper. The Patriots saw fit to create us, and in doing so became our only raison d'étre! I won't fight my fate any longer. I'll kill Zero and Big Boss, and become a Patriot myself.
"Free from FOXDIE... free from the System... free from ID control. Our minds free from their prisons. That is the haven I've yearned for."

"War has changed. Our time has ended. Our war is over. But there's one more thing I must do... one last punishment I must endure. Erase my genes... wipe this meme from the face of the Earth. This... is my final mission."

"Snake... had a hard life. He needs some time to rest."
"...this is good...isn't it...?"
