"The Endless broke us when they broke themselves. Now we are few and many that remain are of little use. Yet our purpose still drives us; even death cannot be allowed to stop us. We must find new converts, new servants, who will help us fulfill the great oaths we took so long ago. They will not only be our hands and our eyes, they will be the sword and the shield of our armies that will bring the Eternal End. First upon Auriga, and then across the universe."

"They are weak. They are soft. They writhe in supposed discomfort at minor penances that the faithful would not even notice. Their sloth will be their undoing; without the pain, they cannot touch the power. Use your eyes! Or I will remove them in atonement. See that Auriga herself writhes in anguish -- as we all should. Join me in contrition and mortification such as Auriga has never seen. Together we will embrace the agony, and make it our servant."

"I am many things, I have been many things. Warm and green, cold and gray. Devastated and dying. Now I am alive again, but I fear my new children imitate the old ones. Some claim the mountains or the forests, or build fortresses on the plains. They begin to mistrust, and prepare for war. Still, I love them as as only a mother can. And now I fear for them. I feel the winds of change begin to blow... And this time it may be an all-out storm. I pray that my children will weather this tempest; for nothing is immortal, and one day they may have to survive without me."

"The colony was everything. They were born as one, they fought as one and they died as one... driven by their hunger. But I hunted for something more... I stole the sentience of an ancient power and saw a greater purpose. For we were the first; Auriga is our planet. And I will turn our hunger against those trespassers who would take it from us. One day, we will reign supreme on Auriga. And we will gaze up at the stars, still hungry..."

"We were different, once. We fought, drank, an loved as mortal beings. But our world changed and we faced a stark choice: Alter our bodies, or perish. Yet "survival" is not the same as "life". Now we are prisoners of the armor that binds us and the Dust that sustains us. We must drain Dust, drain energy, or die... Where is our honor now, Lords of the Amber Plains? And what matters more -- to reclaim our honor, or sustain our bodies?"

"It's coming... I am convinced. Now, I must convince the others. We have seen the longer winters... We have felt the limits of the Sharing. Our planet is changing, we must change with it. We must leave the forest, start again, explore and reach out. We must find new ways. Adapt. Learn. For if not... we will perish. And that will not happen while I wear the crown."

"Our legend spoke of a great journey beneath the stars. Safe in our holes and mines we ignored these old tales. But then the Great Quake creaked our holes open revealing ancient secrets and relics. Those unknown relics carried our patterns, our images, hints of a hidden past. We took them and fled the destruction seeking a new life on the surface. Now the legends and relics of our past show the way to our future. The journey will be dangerous, sometimes deadly, but we go forth without fear or ignorance, for "courage" and "knowledge" are the bywords of the Vaulters."

"It is said that the worst way to die is to burn."

"A gift to the gods, an Appeasement of Agony to pay for our sins of weakness."

"The insatiability was agonizing rather than merely annoying, and drove it to constant foraging or constant battle in order to feed. Driven to eat its own young, that act - forbidden except in times of urgent desperation - made it an outcast from its hive."

"His rage burned brighter and brighter, until one day in its incandescence he struck out of his birthplace, seeking vengeance."

"Though not in the least a religious man, he is known to recite some sort of phrase or prayer at the end of each successful battle - a mystery whose secret even his closest lieutenants have not unraveled."

"Marines do not fear the cold, the dark, or the enemy."

"Its Us! He's carrying the fuel cell!"

"Why is the right place always so terrifying?"

"Welcome to the last safe City on Earth -- the only place the Traveler can still protect. It took centuries to build. Now... we're counting every day it stands."

"Another one of these hardened military systems... And a few centuries of entropy working against me."

"All ends are beginnings."

"It's a day for pretty speeches and medals. But we know the real fight takes place out there."

"Ah, yes. The Awoken. Out there, wavering between the Light and the Dark. A side should always be taken, little light. Even if it's the wrong side."

"My path's my own."

"I was not forged in light. But I believe where our paths cross, ground...could break."

"Evil so dark it despises other evil."

"I don't even have time to explain why I don't have time to explain."

"Whether we wanted it or not, we've stepped into a war with the Cabal on Mars. So let's get to taking out their command, one by one. Valus Ta'aurc. From what I can gather he commands the Siege Dancers from an Imperial Land Tank outside of Rubicon. He's well protected, but with the right team, we can punch through those defenses, take this beast out, and break their grip on Freehold."

"And that was the end of everything. But it was also a beginning."

"For centuries we feared the forces of Darkness massing against us. We sought to hide and cower beneath a broken god. No more. These Guardians show us what we are, what we have always been and what we will be again. We are what remains of the Light and we will not be stamped out."

"There are many tales, told throughout the City to frighten children. Lately those tales have stopped. Now... the children are frightened anyway."

"Taniks has no House. He kneels before no banner, owes allegiance to no Kell. He is a murderer, and very good at what he does. I have been tracking him since Wolves broke their chains, yes? Now Taniks works for Wolf Pack, but not for long."

"Sylok, the Defiled, thirsts for your Light."

"Often, when we guess at others' motives, we reveal only our own."

"Access key? I don't need an access key. is more complicated."

"[last lines, in a letter left on his wife’s grave] I lived through the Blitz, Pearl — and the fall of Rapture. They took my memory, my voice — everything that made me a man. But nothing ever scared me so much as saying goodbye. I wanted to save you. I couldn’t resist trying to bring you back the only way I knew how. But... You didn’t want that — I know it now. And I think I’m finally ready... To let you go your way. I stand here with sun on my face... And it’s almost like I can feel you smiling. Goodbye, Pearl. I love you more than I’ve got words for. —Milton"

"You're in The Thinker's Core. The code printer is upstairs, in the control booth. Top-level access only: You'll need to confirm your genetic identity to start the printing process."

"So far, so good. I can feel the sunlight already. Now we just print out the mainframe code from The Thinker's central processor so I can take it to the surface and start to rebuild. Computer Core access is at the end of Ops."

"I've got a bathysphere at my lab that should be able to get us the hell out of Rapture, but we can't leave just yet: first, we'll need to reprogram a signal beacon. That nutcase Lamb's got the city on lockdown, but a hacked beacon should keep her torpedoes at bay. See what you can find."

"Wahl's become obsessed with perfecting his "predictive equation." The Thinker can do plenty, but tell the future? No... The splicing drove him mad. Wahl can rot here in Rapture for all I care. We'll make a copy of the Thinker and return it to the land of the living."

"The Lancer is the most technologically advanced Big Daddy that Rapture ever produced. Now it stands between you and the Little Sisters... And if there's anywhere you'll need ADAM to get by, it's Minerva's Den."

"Wahl. He was a brilliant engineer — we saw eye-to-eye once, long ago. But the splicing made him paranoid, delusional. He'd murder us both to keep the Thinker here."

"Sorry I can't be there to meet you in person — you've seen the state of the Den these days. It's the Thinker that's important now, though. I need you to get to the Computer Core and print out a hard copy of The Thinker's machine code."

"Reed Wahl... He and I founded Rapture Central Computing together, but the greedy bastard pushed me out years ago. The Splicers, the security... He pulls the strings in Minerva's Den now."

"Minerva's Den has been cut off from the rest of Rapture for some time... But not cut off from splicing. Don't let your guard down. The Den's gone dark, but if you can reset the local power relay I'll be able to get the juice flowing from here."

"Hello? Mister... Sigma? Can you hear me? The name's Porter, Charles Milton Porter. Doc Tenenbaum tells me you're here to help us get the Thinker out of Rapture. It's not going to be easy, but nothing worth doing ever is. You should be able to get inside through an airlock."

"[from trailer] I dreamed of a computer that could think for itself... And using Rapture's technology, I made that dream reality: A machine that can actually think — reason — for itself!"

"A bleedin' golf club? Who'd have thought? I'm never havin' kids."

"Sander Cohen. There was a man! Sharp suit, good mustache, took no guff!"

"Doctor Lamb says to embrace the man in the mirror. How bloody queer is that?"

"I'm an 'ard man, mate. That's how it is down here: survival of the 'ardest man. Huh…"

"Some thoughts are just wrong. Nasty thoughts. Gotta stomp them thoughts right out!"

"Don't need no one. I got the ADAM, now I got it all; brawn, brains, the whole bleedin' package!"
