you’ve been seeing products of aperture science, until you realize that you can take a tour of the facility. You’ve been touring for a while until you see GlaDOS “ oh, it’s another human touring the facility you got to the final part. This is where I show you some of the history. It started all with Cave Johnson, who found it. I miss him… he invented portals. he hates black Mesa. I do too. he started experimenting with putting a humans mind on a disk to put in a robot. which then he made me before he died he died of Moonrock poisoning really odd way to go out, but then the facility was run by a bunch of scientists until my dumb self fill the facility with neurotoxin they all died except one he’s still sleeping in a cryo- chamber and then she came… I’d rather not talk about her, but she’s the only reason why I don’t kill humans anymore. She changed my life. I don’t really wanna reveal that stuff and then Wheatley oh, I hate him thank God he got launched into space because of her anyways, that is basically the story of aperture. Now we can get. The observation of the test chambers, but is there anything you want to add?”
