{{Spoiler|''Portal 2'' takes place an indeterminate amount of time 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|''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|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.

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.}} | ||

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.

==== The Potato Sack ==== | ==== 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 computer antagonist from Portal 2. The ARG's theme of potatoes is based on plot elements within Portal 2, specifically that for part of the game, GLaDOS's personality module is run off a potato battery. | 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.

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. | Large numbers of people participated in solving the puzzles within the ARG.

==== The First Update ==== | ==== 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. | On the release date of the Potato Sack bundle, players found the games within it had recently received updates.

==== Save/Load Abuse ==== | |||
'''Save/Load Abuse''' (SLA)<ref>https://rules.portal2.sr/#saveload-abuse-sla</ref> is defined as using any unnatural load or level transition (i.e. anything other than touching a changelevel trigger in the map) in order to affect the chance of some event occurring or make an event possible. For instance, saveload clipping is considered SLA, since it achieves an effect which would otherwise be impossible. Similarly, loading saves to retry lucky door skip in sp_a2_bridge_the_gap is SLA, as it affects the overall chance of successfully getting through the door. Exceptions are made to this rule for physics RNG specifically, so that loading saves and getting different physics RNG is not considered SLA, since this RNG is prevalant to the point of being unavoidable. | |||
==== Out of Bounds ==== | |||
We define the player themselves as being out of bounds<ref>https://rules.portal2.sr/#out-of-bounds-oob</ref> if a) the player's eye position goes out of bounds or b) all 8 vertices of the player's bounding box go out of bounds... | |||
The Source Engine has a strict technical definition of whether a point is "out of bounds" based on its BSP world system (a point is out of bounds if it is in a CONTENTS_SOLID leaf and not within a brush)... | |||
==== Pause Abuse ==== | |||
'''Pause Abuse'''<ref>https://rules.portal2.sr/#pause-abuse</ref> is defined as using game pauses (via the ESC key, gameui commands, or opening the developer console) to affect the chance of some event occurring, make an event possible, or otherwise contribute to the run. For instance, the Betsrighter jump in sp_a1_wakeup can be done far more consistently by console pausing as you land - as such, pausing at this moment in the run is considered pause abuse, as it affects your chances of getting the jump. More subtly, pausing while lining up a precise shot is also pause abuse, since the time you are paused can allow you time to read your coordinates and prepare to move your mouse correctly. | |||
