I didn't sign on for this shit. Monsters, sure, but civilians? Who ordered this operation anyway?

I have seen worlds bathed in the Makers' flames. Their denizens fading without so much as a whimper. Entire planetary systems born and raised in the time that it takes your mortal hearts to beat once. Yet all throughout, my own heart, devoid of emotion... of empathy. I... have... felt... nothing! A million, million lives wasted. Had they all held within them your tenacity? Had they all loved life as you do?

Chinese people – who wants to get killed in our movie?

You reap what you sow, Artyom: force answers force, war breeds war, and death only brings death. To break this vicious circle one must do more than act without any thought or doubt.

Eat this, you outer-space octopus!

You are not prepared!

Dr. Freeman, you really shouldn't be out there. At the moment of synapse, as I teleport, this chamber will be bathed in deadly particles that have yet to be named by human science. Perhaps when I have the leisure to do the work myself, I'll name one after you. That way you won't be completely forgotten.
When the singularity collapses, I will be far away from here. In another universe, as a matter of fact! You, on the other hand, will be destroyed in every way it is possible to be destroyed - and even in some which are essentially impossible!

I'd like to take a moment to address you directly, Dr. Freeman. Yes. I'm talking to you, the so-called One Free Man. I have a question for you. How could you have thrown it all away? It staggers the mind. A man of science, with the ability to sway reactionary and fearful minds toward the truth, choosing instead to embark on a path of ignorance and decay. Make no mistake, Dr. Freeman. This is not a scientific revolution you have sparked... this is death and finality. You have plunged humanity into freefall. Even if you offered your surrender now, I cannot guarantee that our benefactors would accept it. At the moment, I fear they have begun to look upon even me with suspicion. So much for serving as humanity's representative. Help me win back their trust, Dr. Freeman. Surrender while you still can. Help ensure that humanity's trust in you is not misguided. Do what is right, Dr. Freeman. Serve mankind.

I am the Swarm. Armies will be shattered. Worlds will burn. Now at last, on this world, vengeance shall be mine. For I am the Queen of Blades.

Did you know you can donate one or all of your vital organs to the Aperture Science Self Esteem Fund for Girls? It's true!

What is better -- to be born good, or to overcome your evil nature through great effort?

You are not a good person. You know that, right? Good people don't get up here.

Well, Gordon, I see your HEV Suit still fits you like a glove. At least, the glove parts do.

Tell my wife, I had another wife.

It was crazy as hell. He must've been tweaking. I know I am. You got a washing machine I could take apart?
