Okay, almost there. On the other side of that wall is one of the old testing tracks. There's a piece of equipment in there we're gonna need to get out of here. I think this is a docking station. Get ready...

Good news: that is NOT a docking station. So there's one mystery solved. I'm going to attempt a manual override on this wall. Could get a bit technical! Hold on!

Cave Johnson: Greetings, friend. I'm Cave Johnson, CEO of Aperture Science. You might know us as a vital participant in the 1968 senate hearings on missing astronauts. And you've most likely used one of the many products we invented - but that other people have somehow managed to steal from us. Black Mesa can eat my bankrupt-...

Caroline: Sir, the testing?

Cave Johnson: Right. Now, you might be asking yourself, "Cave, just how difficult are these tests? What was in that phonebook of a contract I signed? Am I in danger?" Let me answer those questions with a question. Who wants to make sixty dollars? Cash. You can also feel free to relax for up to twenty minutes in the waiting room, which is a damn sight more comfortable than the park benches most of you were sleeping on when we found you. So! Welcome to Aperture. You're here because we want the best, and you're it. Nope. Couldn't keep a straight face.

Good work getting this far, future-starter! That said, if you are simple-minded, old, or irradiated in such a way that the future should not start with you, please return to your primitive tribe and send back someone better-qualified for testing.

This next test is very dangerous. To help you remain tranquil in the face of almost certain death, smooth jazz will be deployed, in three, two, one.

Some emergency testing may require prolonged interaction with lethal military androids. Rest assured that all lethal military androids have been taught to read and provided with one copy of the Laws of Robotics. To share.
