Portal 2 spoilers ahoy. This doesn't seem likely. GLaDOS later reveals that Wheatley was an intelligence dampening core, designed to slow her down by feeding her a constant stream of bad ideas which she would have to process before rejecting. Wheatley's personality does appear to change once he takes over from GLaDOS, but this I suspect is a natural ...

Black Mesa and Aperture Science, the two focal science companies of the Half-life and Portal series exist in the same in-game biverse and, at one point vied for research funding. The Borealis (containing some Aperture Science portal technology) is sought out by the resistance (remnants of Black Mesa and newly freed citizens) for various means. If you wander ...

Chell's backstory has to be inferred from content in the game, as very little is made explicit. We know from Valve's pre Portal 2 Comic "Lab Rat" that Doug Ratmann placed her at the top of the testing queue because GladOS had previously rejected her as being unsuitable for testing due to excessive tenacity, but this tells us little about her origins. ...

This is explained in Portal 2: Lab Rat comic book. Despite the name, it also explain some of the event prior to the first Portal game. Here a quote from her article on half-life.wikia. According to the psychological profile in her personnel file, Chell is "abnormally stubborn" and refuses to ever give up, no matter how daunting the challenge. Originally, ...

First, I made a quick search and found this image here (nothing interesting about the length of a portal on this site, but the image is interesting). Then I made my own tests on Portal 2 (the first image come from the first game, according to Chell's outfit), the result vary as the surface and others factor change, but here are the 2 extremes I found. This ...

She was shut down and disconnected from the world (hence she keeps claiming that Chell "murdered her"), but she wasn't completely offline So in other words - no, she wasn't dead. It was much, much worse...

Speculation, but it seems like it would be safe to assume there has been interaction with GLaDOS or a human before the game begins, and there would have been initial greetings then. You start out in the relaxation chamber; you had to get into there somehow, and I doubt that you could wander into there with no interaction whatsoever. "Hello and again ...

I have a theory!

No, using the portal isn't the same as teleportation. Using portal, you create Quantum Tunnels. While these seem to function like wormholes, they don't bend space-time. The exact working has never been shown in the game. The original name of the Portal device was Aperture Science Portable Quantum Tunnelling Device (Source: Portal 2). It was later known by ...

It’s also noteworthy and forgive me if I didn’t catch this on my way down to the answer box but I believe GLaDOS has a line where she explains what happens when hooked up to the main computer. GLaDOS: The body he’s squatting in - MY body - has a built-in euphoric response to testing. Eventually you build up a resistance to it, and it can get a little… ...

My impression is that other materials also worked. There's a brief extro in Portal 2 where Cave speaks about his experimentation with Moon Dust: "The bean counters told me we literally could not afford to buy seven dollars worth of moon rocks, much less seventy million. Bought 'em anyway. Ground 'em up, mixed em into a gel." "And guess what? ...

I think the intent was just to immediately establish GLaDOS's strangeness; people from Valve claim to have never heard of the "repeated cloning" theory, which is the obvious explanation that would make it actually mean something.

Moon rock can't have been required, because Aperture built the first Aperture Science Portable Quantum Tunneling Devices in the 1950s, before moon rock was available. I think this image is not canonical, but the small graphic in its lower right corner is based on ones that appear in the game (see 2nd picture). This image appears in the 1950s area of the ...

The personality cores were attached to GLaDOS in an attempt to control her, or at least provide some protection against her plans to fill the facility with neurotoxin. The fact that there was an entire bin of failed cores suggests that they tried many variations before finally settling on the ones that were stuck to her in Portal 1 - including the morality ...

As for Caroline, the the song that the turrets sing at the very end of Portal 2 begins with the words (translated from Italian, emphasis mine): Dear beautiful, my beautiful darling! My child, oh Chell! For I hold her in esteem… For I hold her in esteem. Farewell to my dear! As GLaDOS was clearly affected by Caroline's personality, ...

I imagine that if it has a thickness and it's going to be small (really tiny) then you should get your hand cut in two. Even more so if it has no thickness. But the game (at leas the first one) has a feature (switchable in the settings, but on by default) that "nudges" you into a portal if you're moving (falling) towards it but aren't aligned perfectly and ...

The power corrupted him! As you notice, GLaDOS is much more likable when attached to the potato, because she has no power. Similarly, Wheatley became corrupted through the power of being in control over the facility. The crack in his eye was mere coincidence (or maybe a hint to his change) which was caused by GLaDOS grabbing him.

Wheatley is just incompetent at the beginning, but also kind (he tried to help Chell escape). He, and the others like him, were designed to impede/control GLaDOS with their bad ideas. After he plugged into the larger AI, he was strongly compelled to perform scientific experiments which he clearly and quickly became addicted to. Remember; he tried moving the ...

We will probably know more when the next Half-Life episode is released. In the end of Episode 2, they mention a strong connection between the Borealis (which will probably be a fundamental part of Episode 3) and Aperture Science. It is safe to speculate that we will learn more about the connection between both companies in the next instalment. So far we have ...

I wouldn't say they happen at the same time. The events of HL1 and HL2 are 20 years apart. At the beginning of P2 you're in a bed and wake up periodically, but something happens and you're stuck for more time than the clock can track (hence in not rolling over). It can be assumed that you've slept for way over 20 years. Somewhere during P2 GLaDOS states that ...

GLaDOS was created because Apeture was behind on Black Mesa, it was the final challenge to create the superior Disk Operating System. GLaDOS was designed specifically to be victorious against the Black Mesa contract so then it is unlikely that she had any respect for her rival. Furthermore, we know she was turned on on Bring your daughter to work day, and ...

The link between the Portal series and Half-Life series is that both series are in the same world. As in that they have direct relation to each other. In Portal 2, you see in an Easter Egg of the Borealis, from Half-Life 2 being built. We probably will learn more in the next few games, as bitmask has pointed out. But right now you can see that the two ...

Aperture Science is an underground science facility while Black Mesa on the surface. C. Johnson always mentioned about his investor. In Half Life, however, there were not a lot of people who were in a state to invest so we can say that the events of Portal 2 may be in parallel to Half Life, but at the time when Johnson was alive Black Mesa was just a ...
