게임은 첼이 안정실에서 깨어나며 시작하고, 글라도스의 목소리가 브리핑을 해 주고, 포털이 열리며 나가게 됩니다. 플레이어는 잠시 후, 휴대용 포털 장치를 얻게 되며 본격적인 테스트에 들어갑니다. 테스트를 치루면서 글라도스이 의도는 분명해집니다.이 시설은 인간의 삶을 결여시키고, 글라도스는 그것을 첼한테 실험하고 있습니다. 시설 전반에 걸쳐 "굴"이 있는데, 더그 랫맨이라는 살아남은 과학자는 글라도스를 피해다니며 첼을 위해 여러가지 낙서를 남겨 두었습니다. 실험이 끝나고 나면 케이크를 준다고 동기부여를 한 다음, 점점 어려워지는 테스트를 치룹니다. 테스트의 끝 부분에서, 첼은 아주 어려운 테스트를 풀어야 합니다.{{Spoiler|첼이 실험을 다 마치고 나자, 글라도스는 첼을 소각로로 보내 죽이려 합니다. 빠른 생각을 통해, 첼은 휴대용 포털 장치를 이용해 탈출한 다음, 자신만의 방법을 만들어 탈출하려고 합니다.

단계 2: 탈출

첼이 탈출하는 동안, 글라도스는 케이크가 있는 파티가 준비됨과 함께, 첼을 죽이려 했던 시도는 거짓임을 주장하였습니다. 글라도스는 첼이 탈출을 시도하면 케이크는 무산될 수 있다는 발언을 하며, 지속적으로 첼을 비꼬아 조롱합니다. 결국 첼은 마지막으로 글라도스의 '소굴'에 도달합니다. 글라도스는 치명적인 신경독을 사용해서 모두 살해한 적이 있었습니다. 글라도스는 첼에게 동일한 작업을 시도합니다. 포털 장치를 이용해서, 첼은 모든 글라도스의 코어를 긴급 지식 소각로로 데려갔고, 이로 인해 지붕에 큰 구멍이 생겨 글라도스와 첼은 딸려 올라갑니다. 첼은 시설의 주차장에서 잠깐 정신이 들고, 불타는 글라도스가 옆에 있었습니다. 2010년 3월 3일 패치 로 인해 첼은 파티 에스코트 봇에게 끌려가게 됩니다.

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 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 Enrichment Center. He is having a monologue about reality and how the mind sees it, and is shown to be psychotic, forced to take ziaprazidone [sic] to curb the effects of his schizophrenia. Through the story, he carries a 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 Test Chamber 19, 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 Einstein discovering relativity and NASA reaching the Moon. Rattmann expresses his doubts about GLaDOS' reliability, since she always attempts to kill everyone when being powered.

Back to reality, 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, 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, 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. Doug finds Chell in her Cryo-Chamber in the 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 GLaDOS has flooded the Enrichment Center with her neurotoxin. Rattmann, 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 Chell's file, declaring that she's "the one", then puts her on top of the Test Subject list.

Back to the present, 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 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 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. Harry, unaware of her malicious intentions, accepts, "as long as it's for science", thus sealing the employees' fate.

Doug regains consciousness, and his schizophrenia has returned. The Cube can talk again and asks about 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 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 was long dead before the events of Portal 2. 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.

1장: 의례적인 호출 / 2장: 콜드 부트

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 "Hello, you have been asleep for - NINE NINE NINE NINE NINE NINE NI - days."), 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 Personality Core who introduces himself as 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 almost destroying the room, all the while ranting about the huge responsibility of taking care of the test subjects. After successfully navigating the room to the main facility, Wheatley instructs Chell to go retrieve the Handheld Portal Device, 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. Navigating to 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 Handheld Portal Device, before guiding her back into the facility's test chambers. Fixing the broken down facility while Chell is once again put through testing, GLaDOS, bitter at her murder, informs Chell that her black box forced her to relive her own murder again and again for thirty millennia.

3장: 귀환 / 4장: 깜짝 선물

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.

5장: 탈출

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 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 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 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 deep into the depths of the facility.

6장: 추락

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 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.

7장: 재회

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.

8장: 욕구

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 logical paradox. It fails as he nonchalantly provides a false answer, apparently immune to its effect. 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 (P-body and Atlas) 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.

9장: 그가 당신을 죽이는 순간

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.
