I go with the flow and I'm patient if I have something to do while waiting. I'm also lazy but can be determined. Some of my favorite cartoons include Wallace and Gromit, My Little Pony: Friendship is Magic, Adventure Time, Gravity Falls, Arthur, and Garfield and Friends.

{{SpoilerHeavy}}
[[File:Portal Chell.png|thumb|right|150px|Chell, as seen in ''Portal'']]
Throughout the ''Portal'' series, you take on the role of [[Chell]], a young woman trapped within the [[Aperture Science]] facility. Chell is forced to solve tests of varying difficulty in [[Test Chamber|chambers]] designed by a psychopathic AI named [[GLaDOS]]. During the early stages of the testing, Chell is granted usage of the [[Aperture Science Handheld Portal Device]] (commonly referred to as the portal gun), a piece of equipment developed by Aperture Science that allows Chell to create [[portals]] that act as gates between each other, allowing Chell to quickly traverse areas or reach normally unreachable places.

== Portal ==
{{main|Portal}}

''Portal'' has two distinct parts, the test chambers and the escape.

=== {{anchor|Act 1}} Act 1: ''The Test Chambers'' ===
{{main|Test Chamber#Portal 1 Test Chambers|l1=Portal 1 Test Chambers}}
The game begins with Chell awakening in a [[Relaxation Vault]], where she is briefed by the voice of [[GLaDOS]] coming from speakers, before being released through a portal. The player is introduced to the testing process and mechanics, shortly thereafter obtaining the [[Handheld Portal Device|Aperture Science Handheld Portal Device]]. As Chell makes her way through test chambers, it becomes clear {{Spoiler|the facility is devoid of human life and GLaDOS is testing Chell for her own warped definition of 'science'. Throughout the facility are hidden dens, containing mad scribblings from an [[Doug Rattmann|unseen person]] warning others of GLaDOS.}} Motivated with the promise of [[cake]] at the end of the testing, Chell is put through tests of increasing complexity. {{Spoiler|When Chell is no longer of any use to GLaDOS, she attempts to kill Chell by lowering her into an incinerator. Quickly thinking, Chell escapes a fiery fate using the Handheld Portal Device, and she makes her way through the inner facility via maintenance shafts.}}

=== {{anchor|Act 2}} Act 2: {{Spoiler|''The Escape''}} ===
{{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]]. GLaDOS now attempts to do the same to Chell. Using the Portal Device, Chell defeats GLaDOS by removing her [[Cores|personality 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 awakens 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]].}}

== Portal: Still Alive ==
{{main|Portal: Still Alive}}
''Portal: Still Alive'' is an XBOX Live Arcade port of ''Portal'', containing additional content in the form of new advanced chambers, inspired by [[Portal: The Flash Version]], with no additional story material.

== Portal 2: Lab Rat ==
The Lab Rat comic bridges the gap between ''Portal'' and ''Portal 2'', which introduces us to [[Doug Rattmann]], a scientist at Aperture Science {{Spoiler|who survived the Neurotoxin after GLaDOS' first activation at the Bring Your Daughter to Work Day, which made her self-aware and initiated a lockdown on the facility, and killed most of the scientists with neurotoxin.}}
=== Part 1 ===
Part 1 follows Doug Rattmann as he is tracking [[Chell]] through the [[Aperture Science|Enrichment Center]]. He is having a monologue about reality and how the mind sees it, and is shown to be psychotic, forced to take [[Wikipedia:Ziprasidone|ziaprazidone]] [sic] to curb the effects of his schizophrenia. Through the story, he carries a [[Weighted Companion Cube|Companion Cube]] that he hears talking to him and giving him advice. The main story is also intersected with flashbacks of the period during which GLaDOS was still being built, showing Rattmann's involvement in the project.

Soon after discovering Chell, it appears he has not taken his medication for a while, and he takes his two final pills, against the Companion Cube's advice not to take them. A first flashback is shown, with a younger Rattmann overhearing two colleagues saying they put cameras in the cameras, something that an unidentified person is not to suspect. While he runs through the facility and makes another mural, Chell reaches [[Portal Test Chamber 19|Test Chamber 19]], {{Spoiler|and finally GLaDOS' chamber, where she destroys her.}}

Then another flashback set in GLaDOS' chamber is shown. There Rattmann is seen working with his colleague [[Henry]], who compares their breakthrough with GLaDOS to [[Wikipedia:Albert Einstein|Einstein]] discovering [[Wikipedia:General relativity|relativity]] and [[Wikipedia:NASA|NASA]] reaching the [[Wikipedia:Moon|Moon]]. Rattmann expresses his doubts about GLaDOS' reliability, {{Spoiler|since she always attempts to kill everyone when being powered.}}

Back to reality, {{Spoiler|Rattmann reaches for the surface, where he thinks Chell is. When he finds her, the [[Party Escort Bot]] is dragging her back into the facility.}}

Then a third flashback has Henry showing Rattmann the newly designed [[Morality Core]], {{Spoiler|which is supposed to dampen GLaDOS' urge to kill.}}

Again back to reality, the Cube tells Rattmann to run away while he is outside, but feeling he is responsible for the whole mess, he prefers to get back inside, {{Spoiler|and save her.}}

=== Part 2 ===
Part 2 opens with Doug Rattmann traversing the innards of the facility. The Companion Cube informs him that the anti-psychotic he took in Part 1 is starting to work, as the Cube slowly fades to silence. {{Spoiler|Doug finds Chell in her Cryo-Chamber in the [[Extended Relaxation Center|Relaxation Center]], where the Party Escort Bot has placed her. He decides to try to save her by getting to Cryo-Control, but the Sentry Turrets block his way. Finding a panel in the wall, he quickly realizes that GLaDOS' destruction blew the main power grid, and that all the Cryo-Chambers have gone offline as a result, including Chell's. Doug then attempts to run past the Turrets but is struck down. }}

Time for another flashback, this time set after {{Spoiler|GLaDOS has flooded the Enrichment Center with her neurotoxin.}} Rattmann, {{Spoiler|apparently the only survivor,}} is taunted by GLaDOS about his schizophrenia as he escapes from the main testing facility. While GLaDOS continues to taunt and manipulate him, Rattmann manages to reach the file room where he finds {{Spoiler|Chell's file, declaring that she's "the one", then puts her on top of the Test Subject list.}}

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

Another flashback begins, involving Henry having a conversation with GLaDOS. During the conversation, she tells him she {{Spoiler|has lost all interest in killing since she was fitted with a [[Morality Core]] and that she}} would like to perform a recreation of the [[Wikipedia:Schrödinger's cat|Schrödinger's cat]] experiment during "Bring Your Cat to Work Day". She says that, added to the boxes and the cats, she needs a little [[neurotoxin]]. Henry, {{Spoiler|unaware of her malicious intentions,}} accepts, "as long as it's for science", {{Spoiler|thus sealing the employees' fate.}}

Doug regains consciousness, and his schizophrenia has returned. The Cube can talk again and asks about {{Spoiler|Chell being "the one" and how Doug knew she is,}} to which he admits it was just a hunch. The Cube then tells Doug to {{Spoiler|patch Chell's Cryo-Unit in the reserve grid to restart her life support, which works but keeps Chell in an everlasting sleep until she is woken up, "both alive and dead, until someone opens the box".}}

Exhausted, Rattmann crawls into the bed of a [[Relaxation Vault]], and presumably falls asleep. It was later revealed by Valve that Rattmann {{Spoiler|was long dead before the events of Portal 2{{citation needed}}. On the floor, Chell's files scatter on the ground, showing that she should not be tested, as she is "abnormally stubborn and never ever gives up. Ever."}}

{{main|Portal 2}}

=== Single-player ===

==== {{anchor|Chapter 1|Chapter 2}} Chapter 1: ''The Courtesy Call'' (Act 1) / Chapter 2: ''The Cold Boot'' (Act 2)====
{{Spoiler|Following the events of ''[[Portal 2: Lab Rat]]'', Chell is awoken 50 days later in her relaxation chamber, which has the appearance of a motel room, for a 'mandatory physical and mental wellness exercise'. After a brief 'exercise', Chell returns to her sleep. She is awoken an undetermined amount of time later (a pre-recorded message says "[[Media:Announcer openingcourtesy01.wav|Hello, you have been in suspension for - NINE NINE NINE NINE NINE NINE NI-]]"), to the room intercom warning of an imminent core explosion. Her room is in a state of disrepair, and soon, an unfamiliar voice greets her. Upon opening the door she finds herself face to face with a more modern-looking [[Personality Core]] whose name is later revealed to be [[Wheatley]], the jovial AI in charge of the test subjects storage facility. After warning Chell of the likelihood of her having serious brain damage, Wheatley moves her relaxation chamber through the storage facility, crashing several times and largely destroying the room in the process, all the while ranting about the huge responsibility of taking care of the test subjects. After successfully navigating the room to the main testing facility, Wheatley instructs Chell to go retrieve a "[[Handheld Portal Device|gun that makes holes]]," as it will be needed for their escape from the facility. Upon successfully acquiring the device, Wheatley and Chell make their way to GLaDOS' chamber where Wheatley claims an escape pod to the surface is located. They find the chamber partially destroyed, with overgrown wildlife everywhere, and in the middle of the chamber lies the lifeless body of GLaDOS. After reaching the breaker room under the chamber, Wheatley attempts to find the breaker for the lift. In the process, he inadvertently reboots GLaDOS. Bitter at the cause of her death, she crushes Wheatley and tosses him away before dropping Chell into the [[Emergency Intelligence Incinerator]], into the incinerator room. GLaDOS instructs Chell to retrieve the Dual-Portal Device, before guiding her back into the facility's test chambers by navigating backwards through [[Portal Test Chamber 19|Test Chamber 19]]. Fixing the broken down facility while Chell is once again put through testing, GLaDOS, bitter at her murder, informs Chell that her {{W|Flight recorder|black box}} forced her to relive her own murder again and again '''forever'''.}}

==== {{anchor|Chapter 3|Chapter 4}} Chapter 3: ''The Return'' / Chapter 4: ''The Surprise'' ====
{{Spoiler|When GLaDOS isn't watching, Wheatley pops out from behind a test chamber wall and reveals he survived their encounter with GLaDOS. He asks Chell to play along with the testing until he figures out a way for them to escape. GLaDOS' taunts become more vindictive, at one point pretending to reunite the 'orphan' Chell with her family. It becomes clear that Chell does not have much time left, as GLaDOS insinuates her usefulness is coming to an end. While in a test chamber, the power is cut out and Wheatley reveals himself from behind a wall panel, under the false impression GLaDOS cannot detect him. When she does, he and Chell make a run for it through the inner facility with GLaDOS attempting to halt their progress.}}

==== {{anchor|Chapter 5}} Chapter 5: ''The Escape'' ====
{{Spoiler|Along the way, they pass a 'potato power' exhibition, held on the ill-fated 'Bring Your Daughter to Work Day'. While making their way through the [[Turrets|Turret]] production facility, Wheatley reveals he plans to sabotage the Turrets and neurotoxin supply so that when they face GLaDOS she will be unarmed. They successfully carry out their plan by replacing the master Turret template with a [[Defective Turrets|Defective Turret]] and use [[portals]] to redirect a [[Thermal Discouragement Beam]] to cut off the neurotoxin supply lines. Hopeful, they make their way to GLaDOS' chamber once again for a showdown. GLaDOS, once again, attempts to kill Chell but is unsuccessful due to Wheatley's and Chell's sabotage. It is at this point that the [[Announcer]] informs them that the central core, GLaDOS, is 80% corrupt and because Wheatley is present, a core transfer is initialized. This requires both cores' approval, and when GLaDOS objects, a stalemate is reached. The Announcer informs them that a stalemate associate is required to press a stalemate resolution button for the core transfer to occur. GLaDOS desperately attempts to block Chell from doing so, but is unsuccessful, and the core transfer occurs. Wheatley is transferred into GLaDOS' body and she is removed from power. In jubilant mood, Wheatley sends Chell on her way to the surface. He begins laughing, but it becomes unusually powerful for Wheatley. He lowers Chell back down, going on about how he did it. GLaDOS taunts him, telling him that Chell did all the work, and in a fit of rage, he takes her core apart and places her in a potato battery. He tells Chell that he is the boss now, and that she can no longer order him around. PotatOS is then shown off; Wheatley's attempt is to humiliate her. It is at this point GLaDOS reveals that Wheatley was designed to be a moron, in order to dampen GLaDOS' brainpower so that she wouldn't attempt to murder everyone in the facility. Angered by this revelation, Wheatley throws her in the lift with Chell and in a fit of rage smashes the lift downwards, where the lift floor collapses, and they fall into the depths of the facility.}}

==== {{anchor|Chapter 6}} Chapter 6: ''The Fall'' (Act 3) ====
{{Spoiler|Falling several miles down, Chell awakens to find herself in the very bowels of Aperture and the ruins of the old facility. She witnesses the potato GLaDOS being abducted by a bird before making 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 enrichment 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 1950s as a curtain 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]]. In between 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 slowly runs the company into the ground. }}

==== {{anchor|Chapter 7}} Chapter 7: ''The Reunion'' ====
{{Spoiler|It is revealed that in a misguided move in the 1980s, Cave 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. While traveling 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, GLaDOS observes a poster about robot paradoxes and comes up with a plan to stop Wheatley when they face him.}}

==== {{anchor|Chapter 8}} Chapter 8: ''The Itch'' (Act 4)====
{{Spoiler|Chell and GLaDOS return to find the facility in chaos. Several core meltdowns are in progress while Wheatley has been busy modifying the test chambers to his liking, including constructing [[Frankenturrets]] - crudely made walking Turret/[[Weighted Storage Cube]] hybrids. They confront Wheatley and GLaDOS attempts to shut him down by presenting him with a {{W|logical paradox}}. It fails as he nonchalantly provides a false answer, apparently too stupid to understand it. The Frankenturrets, however, short-circuit, humorously indicating that they are smarter than Wheatley. Having Chell and GLaDOS back in his clutches, Wheatley forces them to carry out his tests, revealing the need to test is an 'itch' hardwired into the AI system. Initially Wheatley is satisfied with the testing but soon the euphoria of watching Chell and GLaDOS being tested wears off, as he builds up a resistance to the euphoric response. Growing frustrated with them, Wheatley hints he has found other test subjects ([[Atlas]] and [[P-body]]) and that he has a 'surprise to die for' coming soon. He unleashes his surprise early when Chell steps on a booby trapped [[Aerial Faith Plate]], which transports Chell and GLaDOS to a platform surrounded by spiked crushing plates.}}

==== {{anchor|Chapter 9}} Chapter 9: ''The Part Where {{spoiler|He Kills You}}'' ====
{{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, including Chell, but she 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 [[Atlas]] and [[P-body]] 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 surprises Chell by throwing out the Weighted Companion Cube she incinerated in ''Portal'' and the door down to the facility is closed shut.}}

{{Spoiler|The game ends with a wistful Wheatley floating aimlessly in space, admitting if he was able to go back, he would say he was sorry.}}

'''''Portal 2''''' is the sequel to the award winning and hugely successful ''[[Portal]]'' developed by [[Valve|Valve Corporation]]. It features a single-player story set after the events of ''Portal'''s story; and a brand-new [[Co-op]] game mode, featuring additional [[test chambers]] designed specifically for Co-operative play. ''Portal 2'' was released April 19, 2011 on the Steam platform. Retail release in North America started on April 19, 2011; and later, Europe and Australia on April 21, 2011.

== Plot ==
{{main|Story}}
{{Spoiler|''Portal 2'' takes place an indeterminate amount of time, somewhere between 50 and 50,000 years, after the events of ''Portal'', which saw [[Chell]] destroying the sentient computer [[GLaDOS]], and landing outside the facility, only to be dragged back inside of [[Aperture Science]] where she was ultimately placed in a [[Relaxation Chamber]] by [[Doug Rattmann]] for the indefinite future.}}

{{Spoiler|After considerable time has passed, [[Wheatley]], a [[personality core]], that has helped to maintain Aperture Science during the absence of GLaDOS arrives at the room of the awakening Chell. With a desire to flee the crumbling facility, Wheatley and Chell begin their quest to escape Aperture Science to return to the real world. After separating from Wheatley and completing a series of tests revisited from ''Portal'', Chell reunites with Wheatley and head to what they believe will be escape. They must cross through the chamber of GLaDOS who lies broken and dismembered on the floor of her chamber, they enter the breaker room looking for a way out, and instead accidentally reactivate GLaDOS. They rise up through the floor just in time to witness GLaDOS pulling herself back together and taking over the facility again. Chell and GLaDOS quickly reunite, culminating with GLaDOS using a robotic arm to drop Chell into the incinerator, and guiding her back towards a new series of tests that GLaDOS intends to force Chell to run continuously until she dies.}}

{{Spoiler|Meanwhile, Wheatley attempts to find a way to get out from under GLaDOS and continue their attempt to escape facility, with Chell's help, he intends to disable her turret production line, disable her [[Deadly Neurotoxin]] and then shut her down once again to facilitate their escape. He reunites with Chell and they escape through the bowels of the building. After achieving their goals and enter GLaDOS' now rebuilt chamber, the computer system detects an alternate core and begins the process of a core transfer, which GLaDOS promptly refuses, prompting the Stalemate Button to be activated. Chell works her way to the button, finally hitting it, which then swaps out the cores of GLaDOS and Wheatley. Wheatley, corrupt with the power from the entire facility of Aperture, quickly turns on Chell, and shoves GLaDOS into a potato battery as revenge. He knocks them down an elevator shaft where they fall to the remnants of the previous incarnation of the Aperture facility.}}

{{Spoiler|GLaDOS (in potato form), has now informed Chell that Wheatley was designed to make extremely poor decisions, in order to turn GLaDOS into somewhat of a moron in an effort to control and dampen her homicidal tendencies. She informs Chell that Wheatley's lack of stability is going to cause the destruction of Aperture Science killing everyone and everything inside the facility. Before Chell can decide whether or not to help, GLaDOS is swooped away by a bird and Chell heads off to attempt to find a way back into the primary facility.}}

{{Spoiler|Chell uncovers the remnants of a 1950's Aperture Science guided by the voice of the now deceased Aperture Science founder [[Cave Johnson]]. She enters a series of tests, often having to navigate between them in unconventional ways due to the deterioration of the lower facility. At this time we learn of Cave Johnson's secretary/assistant, [[Caroline]], of whom Cave is rather fond. Chell reunites with GLaDOS in the nest of the bird that took her. GLaDOS, insistent that she can't lie with only 1.1 volts of power, implores Chell to take her with her to put her back in her body and stop Wheatley from destroying the facility. Chell ultimately agrees and attaches GLaDOS to her [[Aperture Science Handheld Portal Device]] and they continue to try to find a path towards the upper facility.}}

{{Spoiler|As Chell continues to run through tests from the 1970's, and 1980's, GLaDOS becomes curious about Caroline and Cave who she keeps hearing in the recorded guidance in test chambers. She comes to a realization, that she chooses not to share with Chell, and they head towards the newer Aperture facility. In an effort to get back up, Chell must turn on pump stations Alpha, Beta, and Gamma which connect [[Repulsion Gel]], [[Propulsion Gel]], and [[Conversion Gel]] to the newer facility. Repulsion and Propulsion Gels were Apertures attempt at a dietary supplement, whereas Conversion Gel, made from crushed up moon rocks which ultimately lead to the death of Cave Johnson, is used as an ideal portal conductor. When painted on any surface, the ASHPD can be used as designed. They reach the newer facility where Wheatley has taken full control.}}

{{Spoiler|Wheatley, now in the body of GLaDOS which has a built in euphoric response to testing, forces Chell to begin a series of tests to fill Wheatley's new found insatiability for testing. These begin with a rather weak attempt by Wheatley to create a test chamber, but ultimately lead to test chambers stock piled by GLaDOS and shoved together crudely by Wheatley. Chell passes through these chambers, and once again finds her way out of the control of Wheatley and into the bowels of the facility. They arrive at Wheatley's test chamber which, he says, has been designed with the entire purpose of not allowing Chell to defeat him. Chell causes Wheatley to destroy a pipe containing Conversion Gel, allowing portals to be used in the chamber which ultimately leads to his destruction. With help from GLaDOS, Chell attaches corrupt personality cores to Wheatley.}}

{{Spoiler|Once the cores are attached to Wheatley, he becomes corrupt, initiating another core transfer. However, in one of the most intelligent premeditated moves Wheatley performs, he has booby trapped the stalemate button, launching Chell back into the chamber, a single portal laying under Wheatley's hanging body. Alive despite the explosion, Chell reaches for her Portal gun, and, remembering that moon dust creates an ideal portal surface, aims it through a hole in the ceiling at a full moon high in the sky. She fires, causing the space core, the adventure core, Chell, and Wheatley still attached to GLaDOS' body flying into space. GLaDOS quickly regains control of her body, knocks Wheatley into space, and pulls Chell back into the facility. GLaDOS monologues regarding no longer having the desire to kill Chell, and instead just wants her to leave the facility forever. She sends Chell up an elevator, past a chorus of turrets singing an opera directly to Chell, and out into a wheat field. Moments later the [[Companion Cube]], burnt and beaten, is thrown up after her and lands on the ground next to Chell.}}

{{Spoiler|Now in space, a remorseful Wheatley comprehends the choices he made, and what he might have done differently. Wishing he had, instead, helped Chell to escape rather than wind up in space.}}

{{Spoiler|The game concludes, yet again, with a song sung by GLaDOS surmising the events of the game. The song, [[Want You Gone]], written by Jonathan Coulton indicates that, despite claims that Caroline has been deleted, is still present inside GLaDOS, and that deleting Chell from her memory bank will make GLaDOS feel better. The song concludes with GLaDOS simply telling Chell she wants her gone.}}

Development on ''Portal 2'' begins shortly after ''[[Portal]]'' was released. It originally was planned to not include any portals in the game, utilizing a new mechanic called '''"F-STOP"'''. ''Portal 2'' was also planned to be set in [[Aperture Science]]'s earlier days, specifically during the 1950's era. When asked one of the members that worked on ''Portal 2'' that the game wasn't going to include portals, and how would the game be a sequel to ''Portal'', and more specifically, use the ''Portal'' title. He replied with, "We'll deal with it later.", hinting it was to focus on the game's mechanics first.

''Portal 2'' was also conceptualized as set after the events of ''Portal'', and [[GLaDOS]] would test the new subject, named [[Mel]], similarly to how it was with [[Chell]]. After playtesters were disappointed after GLaDOS didn't recognize the player as the one who killed her in the first game, Mel was rejected as a result.

Mel also appeared alongside Chell in the co-op mode of ''Portal 2'' for a while before both being ultimately replaced by [[Atlas]] and [[P-body]].

There was also going to be a fourth [[Gel]] planned for the game. Also inspired by "Tag: The Power of Paint", the fourth Gel was named [[Adhesion Gel]]. Bearing a purple texture, it originally allowed Chell to walk up walls. It was canceled due to playtesters became too disoriented and often had motion sickness while trying to pass a [[Test Chamber]] with Adhesion Gel. The coding (although it does not have any texture and bestows no effects on the surface it was painted on), is left in the game files.

=== ARG ===
{{See also|Portal 2 ARG}}
==== The Potato Sack ====
The Potato Sack is the name of an alternate reality game (ARG) created by the Valve Corporation and the developers of thirteen independent video games to promote the release of Valve's title, Portal 2, in April 2011. Valve president Gabe Newell envisioned the game as a "Cross Game Design Event" in December 2010, and allowed the developers a free rein to design the game using Valve's Portal intellectual property. The game, requiring players to find and solve a number of puzzles hidden within updates of the thirteen games, ultimately led to the opportunity for players to release Portal 2 about 10 hours earlier than its planned release by playing games under the pretense of powering up GLaDOS, the sentient {{Spoiler|computer antagonist from Portal 2. The ARG's theme of}} potatoes is based on plot elements {{Spoiler|within Portal 2, specifically that for part of the game, GLaDOS's personality module}} is run off a potato battery.

Large numbers of people participated in solving the puzzles within the ARG. Reaction from players and journalists was mixed; some saw the ARG as a show of strong support and commitment by Valve for independent game development, while others thought the ultimate conclusion was of limited benefit to justify buying the games to begin with.

==== The First Update ====
On the release date of the Potato Sack bundle, players found the games within it had recently received updates. Most provided an immediate cosmetic change by replacing or adding assets that referred to potatoes. When players started looking deeper into these new assets, they discovered a series of glyphs that referred to other games associated with specific letters, as well as nonsense sentences that lead to specific cyphers. Other hints were less direct, using online services such as Twitter and YouTube to embed clues. In the case of Toki Tori, sections of new levels included braille code that referred to latitude and longitude coordinates of Two Tribes' headquarters. One player, "Jake_R", traveled to Two Tribes, where he discovered the glyphs and cyphers posted outside their headquarters. Several of Two Tribes' developers, upon learning of his presence, began filming him from a barbershop across the street. They would later use this footage of him climbing a pole to find these clues as part of another clue during the second phase.
==== The Second Update ====
On April 7, each of the games in the Potato Sack received a second major update. Players found that by completing certain tasks in the game, they would be presented with login screens for the fictional Aperture Science corporation within the Steam interface. Other tasks and clues led to passwords that could be used to log into these Aperture Science screens. These provided players with compressed archives of pictures that consisted of Portal 2 artwork, including photographs from around Seattle (where Valve is based) embedded in their alpha channels.

{{main|Portal 2 - Education Version}}
During a keynote presentation at the {{w|Games for Change|Games For Change}} festival in 2011, Valve director Gabe Newell mentioned that the company was beginning to work with schools to build curricula around ''Portal 2'', looking into "how to teach attraction, repulsion... [they] need to be clear on what their metrics are... what the outcome is, what they're optimizing for".<ref>[http://kotaku.com/5814405/ Kotaku: "Liveblogging Whatever Smart Stuff Gabe Newell Has to Say Today"].</ref>
