Story: Difference between revisions

{{Spoiler|While Chell is making her way through the facility, GLaDOS attempts to lure her back with promises of cake and a party, and claims the attempted murder of the player was a misunderstanding. When she realizes her attempts are in vain, GLaDOS resorts to taunting Chell while continuing her efforts to kill her. Eventually Chell reaches GLaDOS' lair, where she finally comes face to face with the rogue AI. It is revealed that GLaDOS had murdered everyone in the facility using deadly [[neurotoxin]]s. GLaDOS now attempts to do the same to Chell. Using the Handheld Portal Device, Chell defeats GLaDOS by removing her AI cores and depositing them in a nearby [[Emergency Intelligence Incinerator]], resulting in a large explosion that blows a hole in the roof dragging both Chell and GLaDOS upwards. Chell awakes to find herself above ground in the parking lot of the facility, with the burning remains of GLaDOS surrounding her. The [[March 3, 2010 Patch (Portal)|March 3, 2010 Patch]] modified the ending so that Chell is dragged back into the facility by the unseen [[Party Escort Bot]].}}

Back to the present, Rattmann is lying on the floor, wounded by the Turrets, reaches out to his Companion Cube but loses consciousness.

{{Spoiler|Falling several miles down, Chell awakens to find herself in the very bowels of Aperture and the ruins of the old facility, before witnessing the potato GLaDOS being abducted by a bird. Chell makes her way through the ruins and enters through a closed off area to find the old Aperture Science facility. A voice recording plays, welcoming the visitor to Aperture. The speaker introduces himself as [[Cave Johnson]], founder and CEO of Aperture, and introduces his secretary, [[Caroline]]. As Chell makes her way through the old facility via testing spheres, Cave Johnson guides the player through the tests while gradually revealing the history behind Aperture. It is discovered that Cave Johnson founded the company in the 1950's as a curtains manufacturer, becoming a self-made billionaire, before expanding into a science research company. He built the facility in large salt mines beneath {{W|Michigan}} with the intention of competing with [[Black Mesa]]. Inbetween lawsuits against his company for various mishaps and his personal rivalry with Black Mesa, who he claims stole much of his company's research, Cave Johnson slowly runs the company into the ground. It is revealed that in a misguided move in the 1980's, he bought $70 million worth of Moon rocks to grind up. The resulting [[gel]] was toxic, and Cave Johnson falls gravely ill. Chell is reunited with the potato GLaDOS, found in a bird's nest, and GLaDOS insists they need to stop the corrupted Wheatley before his actions cause the destruction of the facility.}}

{{Spoiler|While travelling with Chell, GLaDOS comes across a portrait of Cave Johnson and Caroline, whom she finds vaguely familiar. She then finds herself unwittingly parroting a conversation between Caroline and Cave Johnson. Highly stressed, she manages to overload her battery and shuts off temporarily. Cave Johnson's voice on the recordings now sounds frail and it is clear his health is quickly deteriorating. In a last ditch attempt to survive, he instructs his engineers to start research into artificial intelligence, so that his mind can be transferred into a computer. Angry at the state of affairs, he instructs his employees that if he dies before the AI is complete, Caroline is to take charge of the facility, against her wishes. He also informs them that she can take his place in the AI. No more recordings are made, but it becomes clear that Caroline's mind was inserted into the AI, and is now a part of GLaDOS. Learning this, GLaDOS' attitude slowly changes. She begins praising Chell's progress, and claims to have turned a new leaf. While making their way back up to the facility, and Wheatley, GLaDOS observes a poster about robot paradoxes and comes up with a plan to stop Wheatley when they face him.}}

{{Spoiler|Escaping the trap, Chell and GLaDOS make their escape through the inner facility, avoiding Wheatley's attempts to kill them. They come across a room containing rejected corrupted cores and GLaDOS formulates a plan. She stays behind to carry it out while Chell makes her way to Wheatley's lair for the final confrontation, where he reveals the facility will self destruct in six minutes. They do battle and during its course, Chell manages to attach 3 corrupted cores onto Wheatley. This results in a core corruption of 100% and the Announcer intervenes to initiate a core transfer. GLaDOS inserts herself as the substitute core and hurries Chell to press the stalemate resolution button. Wheatley, anticipating this outcome, has booby trapped the button and it explodes as Chell attempts to press it. She survives the explosion, to the disdain of Wheatley. With the last of her strength, she grabs the Handheld Portal Device and shoots a portal at the Moon's surface. The resulting portals cause everything in the room to be sucked into the vacuum of space, but Chell manages to hang on by grabbing hold of the panicking Wheatley. GLaDOS uses a mechanical arm to detach Wheatley from his body, who is then sucked into space, and pulls Chell back through before closing the portal. Chell wakes up later to find a worried [[P-body]] and [[Atlas]] watching over her and GLaDOS back in her body and back in charge of the facility. She thanks Chell for helping her find the Caroline inside her, before promptly deleting all traces of her. She reveals she has become weary of trying to kill Chell, and that the best course of solution is to give Chell what she wants. Her freedom. She sends Chell on her way to the surface, where along the way she is serenaded by a Turret opera. Reaching the top a door opens, and Chell steps out into a picturesque sunny cornfield where the door promptly shuts behind her. Taking in her freedom, GLaDOS has one last surprise. The Weighted Companion Cube she incinerated in ''Portal'' is thrown outside with her and the door down to the facility is closed shut.}}
