The pride of a Soldier (Metal Gear Solid: Portable Ops)

(Snake draws his pistol at Cunningham)

Cunningham: What do you think you're doing, Snake? Are you still blinded by your loyalty to the CIA? What has the CIA ever done for us in FOX? They sent us on the most brutal missions. And when I came back wounded, they shuffled me to a desk job. They did the same to you, too. They cast your mentor - the mother of our Special Forces - out into a foreign land and left her there to die!

(Snake's aim is unwavering)

Cunningham: Don't tell me you're doing it for the Russian soldiers here. Pathetic fool. Go to the heliport, Snake. I'm not letting you through. Go back.

(A still frame of Jonathan, Roy Campbell, and Elisa)

Snake: I can't let you use Metal Gear. I'm doing this out of loyalty to myself. I'm not going to live my life the way The Boss did!

(Cunningham laughs)

Cunningham: Have it your way. Now you're a real traitor!

Soldiers without a name (Metal Gear Solid)

Solid Snake: Who are you?

Gray Fox: I am like you. I have no name.

Love in the battlefield (Metal Gear Solid)

Otacon: Have you ever... loved someone?

Solid Snake: That's what you came to ask?

Otacon: No, I was wondering if even soldiers fall in love.

Solid Snake: What are you trying to say?

Otacon: I want to ask you. Do you think love can bloom even on a battlefield?

Solid Snake: Yeah. I do. I think at any time, any place, people can fall in love with each other. But if you love someone, you have to be able to protect them.

The siblings (Metal Gear Solid)

Trecho do diálogo entre Solid Snake e Liquid Snake no topo da torre de comunicações

[Liquid suddenly appears in the Hind]

Liquid Snake: So the Snake's finally come out of his hole? Are you ready now... my brother?

Solid Snake: Why are you calling me brother? Who the hell are you?

Liquid Snake: I'm YOU. I'm your shadow.

Solid Snake: What?

Liquid Snake: Ask the father that you killed. I'll send you to hell to meet him.

The Boss' end (Metal Gear Solid 3: Snake Eater)

Trecho do discurso de The Boss antes da última batalha com Naked Snake

The Boss: "I raised you, and loved you, I've given you weapons, taught you techniques, endowed you with knowledge. There's nothing more for me to give you. All that's left for you to take is my life."
