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.'. I figured out what that thing you just incinerated did. When this piece is dropped into the incinerator, GLaDOS's voice becomes darker and more ominous and she tells Chell 'Good news. GLaDOS claims she 'has no clue what it is'. After a short conversation, a piece of her falls out (the Morality Core). Once Chell leaves the approved course, she eventually finds the main chamber where GLaDOS' chassis is.

When a player finally incinerates it (they can't move on in the game if they don't), GLaDOS congratulates Chell on the fact that she incinerated her companion cube 'faster than any other test subject on record'. Many players get very, very attached to this cube. One example of this is found in the infamous 'companion cube' incident, where she says the Companion Cube must be 'euthanized', which is a very helpful object that Chell takes with her throughout the 17th test chamber, characterized by the pink heart design on its sides. She also psychologically abuses Chell in many cases. As the game progresses, she increasingly becomes more and more violent trying to kill Chell many times by means of a fire pit and putting her in a 'live fire course, designed for military androids' because the current testing room was undergoing 'maintenance'. GLaDOS works to see how experimental technology is handled at the hands of test subjects. Since the core had been installed, it can be assumed that the release happened as the core was being installed, forcing the scientists (at least, those who survived) to abandon the facility. There are no clear speakers or units which create GLaDOS's voice, though it is present throughout the facility.Дuring the final battle, GLaDOS reveals it is the source of the facility's abandoned state she flooded the Enrichment Center with a deadly neurotoxin, presumably killing many scientists, just before her Morality Core was installed. The core swings continuously, dislodging one of the modules in the final level. The core hangs from the ceiling surrounded by video screens that show random and irrelevant images.

GLaDOS' core is mounted in a large, sealed chamber alongside control consoles and an incinerator. However, GLaDOS is much more than what she was originally intended for the AI is installed as the Enrichment Center's central control computer. GLaDOS is described as not only being a fuel line de-icer but being fully functional and 'arguably alive'. as a method of de-icing fuel lines in direct competition with a similar project by Black Mesa Research. An abandoned slideshow presentation in a meeting room shows GLaDOS was developed by Aperture Science Laboratories Inc. GLaDOS's origins are gradually revealed in the later stages of the games.
