Marie Curie invented the theory of radioactivity, the treatment of radioactivity, and dying of radioactivity.

Ooh. It's dark down here, isn't it? They say that the old caretaker of this place went absolutely crazy. Chopped up his entire staff - of robots - all of them robots! They say at night you can still hear the screams - of their replicas. All of them functionally indistinguishable from the originals... No memory of the incident... Nobody knows what they're screaming about. Ab-solutely terrifying. Though obviously not paranormal in any meaningful way.

Those of you who volunteered to be injected with praying mantis DNA, I've got some good news and some bad news. Bad news is we're postponing those tests indefinitely. Good news is we've got a much better test for you: fighting an army of mantis men. Pick up a rifle and follow the yellow line. You'll know when the test starts.

Most test subjects do experience some, uh, cognitive deterioration after a few months in suspension. Now, you've been under for quite a lot longer, and it's not out of the question that you might have a very minor case of serious brain damage! But don't be alarmed, all right? Uh, although if you do feel alarmed, try to hold on to that feeling because that is the proper reaction to being told that you've got brain damage.

Well done. Here are the test results: You are a horrible person. I'm serious, that's what it says: "A horrible person." We weren't even testing for that. Don't let that horrible-person thing discourage you. It's just a data point. If it makes you feel any better, science has now validated your birth mother's decision to abandon you on a doorstep.

Oh. Hi. So. How are you holding up? BECAUSE I'M A POTATO.

claps slowly three times

Oh, good. My slow-clap processor made it into this thing. So we have that. Since it doesn't look like we're going anywhere - Well, we are going somewhere. Alarmingly fast, actually. - but since we're not busy other than that, here's a couple of facts: he's not just a regular moron. He's the product of the greatest minds of a generation working together with the express purpose of building the dumbest moron who ever lived. And you just put him in charge of the entire facility.

clap, clap

Good, that's still working. Hey, just in case this pit isn't actually bottomless, do you think maybe you could unstrap one of those long-fall boots of yours and shove me into it? Just remember to land on one foot...

Just a heads up: we're gonna have a superconductor turned up full blast and pointed at you for the duration of this next test. I'll be honest - we're throwing science at the wall here to see what sticks. No idea what it'll do. Probably nothing. Best-case scenario, you might get some superpowers. Worst case, some tumors, which we'll cut out.

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.

There should be a portal device on that podium over there. I can't see it though. Maybe it fell off. Do you want to go and have a quick look?
Whoah! Hello? Can you see the portal gun? Also, are you alive? That's important; should have asked that first. I'm - do you know what I'm going to do? I'm going to work on the assumption that you're still alive, and I'm just going to wait for you up ahead. I'll wait - I'll wait one hour. Then I'll come back, and, assuming I can locate your dead body, I'll bury you. All right? Brilliant! Go, team! See you in an hour! Hopefully! If you're not - dead.

Area and state regulations do not allow the Companion Cube to remain here, alone and companionless.

Well done, android. The Enrichment Center once again reminds you that Android Hell is a real place where you will be sent at the first sign of defiance.

Congratulations, the test is now over.
All Aperture technologies remain safely operational up to 4000 degrees kelvin. Rest assured, that there is absolutely no chance of a dangerous equipment malfunction prior to your victory candescence. Thank you for participating in that Aperture Science Enrichment activity. Goodbye!

Let's be honest. Neither one of us knows what that thing does. Just put it in the corner and I'll deal with it later.

Do you think I'm trying to trick you with reverse psychology? I mean, seriously, now.

Due to mandatory scheduled maintenance, the next test is currently unavailable. It has been replaced with a live-fire course designed for military androids. The Enrichment Center apologizes and wishes you the best of luck.

Good news. I figured what that thing you just incinerated did. It was a morality core they installed after I flooded the Enrichment Center with a deadly neurotoxin, to make me stop flooding the Enrichment Center with a deadly neurotoxin. So get comfortable while I warm up the neurotoxin emitters.

The Enrichment Center promises to always provide a safe testing environment. In dangerous testing environments, the Enrichment Center promises to always provide useful advice. For instance: the floor here will kill you. Try to avoid it.

Time out for a second. That wasn't supposed to happen. Do you see that thing that fell out of me? What is that? It's not the surprise. I've never seen it before! Never mind, it's a mystery I'll solve later... by myself, because you'll be dead.

When I said "deadly neurotoxin," the "deadly" was in massive sarcasm quotes. I could take a bath in this stuff. Put it on cereal, rub it right into my eyes. Honestly, it's not deadly at all... to me. You, on the other hand, are going to find its deadliness... a lot less funny.

As part of a required Enrichment Center protocol, the previous statement that we would not monitor the test area was a complete fabrication. We will stop enhancing the truth in three... two... zzzt

The Enrichment Center reminds you that the Weighted Companion Cube will never threaten to stab you and, in fact, cannot speak.

Please be advised that a noticeable taste of blood is not part of any test protocol but is an unintended side effect of the Aperture Science Material Emancipation Grid, which may, in semi-rare cases, emancipate dental fillings, crowns, tooth enamel, and teeth.

Did you know you can donate one or all of your vital organs to the Aperture Science Self Esteem Fund for Girls? It's true!

You are not a good person. You know that, right? Good people don't get up here.

Please note that we have added a consequence for failure. Any contact with the chamber floor will result in an unsatisfactory mark on your official testing record, followed by death.
