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

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!

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

Gordon Freeman, in the flesh - or, rather, in the hazard suit. I took the liberty of relieving you of your weapons. Most of them were government property. As for the suit, I think you've earned it. The borderworld, Xen, is in our control, for the time being... thanks to you. Quite a nasty piece of work you managed over there; I am impressed. That's why I'm here, Mr. Freeman. I have recommended your services to my... employers, and they have authorized me to offer you a job. They agree with me that you have limitless potential. You've proved yourself a decisive man so I don't expect you'll have any trouble deciding what to do. If you're interested, just step into the portal and I will take that as a yes. Otherwise, well, I can offer you a battle you have no chance of winning... rather an anticlimax after what you've just survived. Time to choose...
