"This is for the record. History is written by the victor. History is filled with liars. If he lives, and we die, his truth becomes written - and ours is lost. Shepherd will be a hero, 'cause all you need to change the world is one good lie and a river of blood. He's about to complete the greatest trick a liar ever played on history. His truth will be the truth. But only if he lives, and we die."
— Captain Price

"The more things change, the more they stay the same. Boundaries shift, new players step in; but power always finds a place to rest its head. We fought and bled alongside the Russians; we should've known they’d hate us for it. History is written by the victor, and here I am, thinking we'd won. But you bring down one enemy and they find someone even worse to replace him. Locations change, the rationale, the objective. Yesterday's enemies are today’s recruits. Train them to fight alongside you and pray they don’t eventually decide to hate you for it, too."
— General Shepard

"As we express our gratitude, we must never forget that the highest appreciation is not to utter words,

[Cortanna] Thanks for the tank, HE never gets me anything. [Johnson] Oh I know what the ladies like.

"Dear humanity, we regret being alien bastards, we regret coming to earth, and we most definitely regret that the Corps just blew up our raggedy ass fleet!" - Sgt. Johnson
