"Remember that NSF prisoner I was interrogating back on Liberty Island? Guess you were bitten by the same bug. There's only one cure, you know, once you've caught the disease..."

"I'm the more advanced model, Denton. It's time for you to retire."

"What an expensive mistake you turned out to be. I've ordered the troops to kill you, because quite frankly I don't have the patience to wait for one of those damn killswitches to work."

"You will confess, by the way. I don't like to dirty my hands with that sort of thing, but you will confess."

"You take another step forward and here I am again, like your own reflection repeated in a hall of mirrors."

"You can't run, Denton. Even if you escape, your killswitch is counting down. You'll be dead in twenty-three hours. Another fifty billion dollars down the drain."

"One must admire a man who can keep a secret, because he has value. What you know more than others makes money, and gives you a measure of power."

"Once the bug bites, you've already lost the patient."

"Oh my God, JC! A bomb!"

"One thing the Air Force never understood: I'm dependable. No matter what, I'm dependable."

"What am I? A bum? You think I'm gonna drink anything you find lying around?"

"Listen to your brother, JC. Respect his experience. Let's leave it at that."

"Area 51. You heard of it, right?"

"[if the player attacks him once] Someone should knock you upside the head a few times, punk. Dismissed."

"There's a time and a place for security, but the legislature has to stay vigilant, or there will be abuses."

"Let's get one thing straight: we've got our share of crooked bureaucrats -- fact -- but this is still UNATCO, and by and large the people in this building are twenty-four carat gold."

"My unit killed a bunch of Afghans one time, but we weren't proud of it. In fact, our liaison at the UN went to the funeral."

"Direct intervention is always part of the game. In my day, we were just more civilized about it."

"I guess it's not surprising to find a few crooks in a place protected by security procedures. The shadow of secrecy; it protects indiscriminately."

"A pistol is more than adequate. Hell, I dispatched a whole platoon one time with a pocket knife."

"Try to remember: people have rights. Don't just shoot everything that moves."

"In my day, international peacekeepers were citizens first and soldiers second. You can forget about that extra ammo. I'm only going to give you the multitools; I think you should concentrate more on mission objectives and less on the enemy body count."

"Being a soldier isn't just following orders, it's following those orders in the service of a higher cause. When that cause is betrayed, we're not soldiers anymore, just pieces on a chess board dying for the wrong reason."

"Some say concentrated power leads to abuse, but I believe that if an institution has a solid foundation it can survive the narrow aspirations of the people it employs."

"I'll make you a deal. Leave now and you will be made comfortable under the new world order."

"No! Don't listen to Everett. He and the Illuminati have been afraid from the beginning, afraid of US, afraid of nano-augmentation. Consider your powers, your strength, your intelligence. You've only had a small taste. Let me finish the project! Let me bring infinite power to the human body! You will not be left behind..."

"Go ahead! Blow this place sky-high... You might get rid of ME, but you'll take down Aquinas, the power grid, the whole electronic infrastructure - is that what you want?! Are you completely nuts?!"

"No! You fool!... Helios will destroy you. I'm the only one who can merge and take control. Wait for ME! I promise you will have a place in the new order..."

"Soon I will leave this body and death will have no meaning."

"Look at you: You're nothing but a little man... a little man still living inside a body. Lose your body and what are you? Nothing! You vanish! You die..."

"A moment more, and I will be like nothing you've ever seen; a new life-form, everywhere and nowhere, like air or radiation, redundant, self-replicating, always evolving..."

"What do you want? Money? You can have VersaLife, the whole damn company. Power? I'll get you on Mead's cabinet! I'm serious, just forget about that last reactor!"

"All right. I get the picture. You want a piece of the pie, or you're going to toss the whole pie out the window. Fair enough. You can have anything you want. How about Europe? Your own continent. Just let me complete my preparations..."

"A cure? A cure!? Do you have any idea how easy it will be for me to make a new virus? All I have to do is find a very large prime number and multiply."

"I'm always pleased to see one of my experiments perform so well. You aren't even afraid, are you? We got a lot of things right when we made you Denton, but don't worry -- I know your weaknesses."

"What's the rush? Take a look around. This facility is where you were born. I've arranged an appropriate fate for you through the hallway to the north. A poetic death, just a few yards away from where you were created."

"I will be the one to merge! The one to see and know everything, to rule, to rule everything..."

"[if JC kills the man who killed his parents] Barely a scratch. You're a little faster on your feet than your daddy was."

"One can be too self-sufficient, I'm coming to believe."

"I'm like the Russian researcher who contracted his own virus. They want to study the way I die."

"This isn't a training exercise, JC. Your targets will be human beings. Keep that in mind."

"Do what you think's right, JC. Only listen to your own conscience."

"I'm not going to stand here and listen to you badmouth the greatest democracy the world has ever known."

"I'm not big into books."

"A forgotten virtue like honesty is worth at least twenty credits."

"What a shame. [said after NPC Gilbert Renton dies. JC says this even if he caused Renton's death]"

"You've got ten seconds to beat it before I add you to the list of NSF casualties."

"What good's an honest soldier if he can be ordered to behave like a terrorist?"

"Every war is the result of a difference of opinion. Maybe the biggest questions can only be answered by the greatest of conflicts."

"Human beings may not be perfect, but a computer program with language synthesis is hardly the answer to the world's problems."
