Gordon Sargent: So you're in, big guy? Or are we gonna have to kill ya?
Niko Bellic: Well, since you put it that way... I'm in.

Elizabeta: Everyone's a rat!
Niko: Not me.

War is when the young and stupid are tricked by the old and bitter into killing each other.

Jimmy De Santa: Hey, let's bounce.
Michael De Santa: Bounce? We're bouncing now? Is that what we're doing? Jesus fucking Christ.

Dr. Isiah Friedlander: Your son, James. He's a good kid?
Michael De Santa: He's a good kid? A good kid? Why? Does he help the fucking poor? No. He sits on his ass all day, smoking dope and jerking off while he plays that fucking game. If that's our standard for goodness... then no wonder this country's screwed.

You can't shake no hands when ye fist be clenched.

Scientist: "Do you think we should appeal to the alien authorities?"
Scientist 2: "Absolutely not!"

Mister, if you can get the power on, that train will take us straight to the surface. I would try it myself, but it's a long way down the generator room, and there are... things, in the way...

Eli Vance: Ah, Gordon. Here you are. We just sent the sample down to the test chamber.
Scientist 2: We boosted the anti-mass spectrometer 105 percent. Bit of a gamble, but we need the extra resolution.
Scientist 3: The administrator is very concerned that we get a conclusive analysis of today's sample. I gather they went to some length to get it.
Eli Vance: They're waiting for you Gordon, in the test chamber.

Well, so much for the government, their idea of containment is to kill everyone associated with the project! Judging by your hazard suit I'd say you were part of what went wrong, isn't that right? Now look, if anyone can end this catastrophe it's the science team in the Lambda Complex at the opposite end of the base. With the transit system out I couldn't tell you how to get there, but there's an old decommissioned rail system somewhere through here, beyond the silo complex. If you can make it through the rocket test labs, you might be able to worm your way through the old tunnels to track down whatever's left of the Lambda team. You can trust them. You can trust all of us. Good luck.

Eli Vance: "Why didn't they listen? We tried to warn them."
Scientist 2: "I never thought I'd see a resonance cascade, let alone create one."
Eli Vance: "Gordon, you're alive! Thank God for that hazard suit. I'm afraid to move him and all our phones are out. Please get to the surface as soon as you can and let someone know we're stranded down here. You'll need me to access the retinal scanners. I'm sure the rest of the science team will gladly help you."

Come in, Cooper! Do you copy? Forget about Freeman, we're abandoning the base. If you have any last bomb targets, mark them on the tactical map. Otherwise, get the hell out of there! Repeat, we are pulling out and commencing airstrikes, give us targets or get below!

Gordon Freeman - it is you, isn't it? The Science Team has been tracking your progress with the Black Mesa security system. Unfortunately, so has the military. That suit of yours is full of tracking devices. Still, it's better than going naked in this place. It's cold in there, and you'll have to hurry. It could sap your suit power in a matter of moments! If you're bent on reaching the Lambda Complex, then you'll want to keep to the older, industrial areas where the security system is full of holes. It's worked for me, so far.

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

Eat this, you outer-space octopus!
