[[File:Portal1 StorageCube.png|right|250px]]&lt;br /&gt;
&#039;&#039;&#039;Cubes&#039;&#039;&#039; are common testing elements throughout the &#039;&#039;Portal&#039;&#039; series that kill you in real life ffffff.&lt;br /&gt;

== Cubes ==&lt;br /&gt;
=== Weighted Storage Cube ===&lt;br /&gt;
[[File:Portal2 StorageCube.png|left|100px]]&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;&#039;Weighted Storage Cube&#039;&#039;&#039; was first introduced in &#039;&#039;Portal&#039;&#039;, and remains prevalent in &#039;&#039;Portal 2&#039;&#039;. In &#039;&#039;Portal 2&#039;&#039; however, the cube is given a blue ring in the center instead of a blue cross, and can turn yellow when placed upon a [[Heavy Duty Super-Colliding Super Button|Super Button]].&lt;br /&gt;

{{Main|Weighted Companion Cube}}&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;&#039;Weighted Companion Cube&#039;&#039;&#039; was first introduced in &#039;&#039;Portal&#039;&#039;, and remains prevalent in &#039;&#039;Portal 2&#039;&#039;. Similar to the Weighted Storage Cube, the Companion Cube possesses a different design in &#039;&#039;Portal 2&#039;&#039;. The Cube functions in the same way as a Weighted Storage Cube, being differentiated to encourage test subjects to feel attached to the Cube. {{spoiler|A feature to the new Companion Cube in &#039;&#039;Portal 2&#039;&#039; is that it is able to sing.}}&lt;br /&gt;

&lt;br /&gt;
=== Edgeless Safety Cube ===&lt;br /&gt;
[[File:ESC.png|left|100px]]&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;&#039;Edgeless Safety Cube&#039;&#039;&#039; was officially introduced in &#039;&#039;Portal 2&#039;&#039;, where it is used only in the [[Cooperative Testing Initiative|co-op]] campaign. However, it also appears once in the single-player campaign as garbage. The entire name is given out of irony, however it still retains the coloring scheme and patterns present in the designs of the other cubes.&lt;br /&gt;
&lt;br /&gt;
The Edgeless Safety Cube did have an appearance in a &#039;&#039;Portal&#039;&#039; Challenge Map, however it was unnamed and also did not have an accompanying receptacle, thus is not widely considered to have its first appearence until &#039;&#039;Portal 2&#039;&#039;.&lt;br /&gt;

{{Main|Discouragement Redirection Cube}}&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;&#039;Discouragement Redirection Cube&#039;&#039;&#039; was introduced in &#039;&#039;Portal 2&#039;&#039;. Its main purpose is to redirect the [[Thermal Discouragement Beam]] to other places or through [[portals]] if necessary. However, the cube has a second use as a Weighted Storage Cube, as it can be used to activate the Heavy-Duty Super Button.{{Clr}}&lt;br /&gt;
&lt;br /&gt;
=== Scalable Cube ===&lt;br /&gt;
[[File:Scalable_Cube.png|left|100px]]&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;&#039;Scalable Cube&#039;&#039;&#039; is exclusively featured in the [[Portal 2 Sixense MotionPack DLC|Portal 2 Sixense DLC]] Test Chambers. The only way to scale the Cube is with the [http://www.razerzone.com/minisite/hydra Razer Hydra] Controllers, a feature supported by the [[Handheld Portal Device|Portal Gun]] in the DLC. The size of the Cube changes simultaneously with its mass. The Scalable Cube can be used to build bridges between gaps or to crush [[Turrets]].&lt;br /&gt;
{{Clr}}&lt;br /&gt;
&lt;br /&gt;
=== Contraption Cube ===&lt;br /&gt;
[[File:Portal_2_-_Contraption_Cube.png|right|100px]]&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;&#039;Contraption Cube&#039;&#039;&#039; is exclusively featured in the [[Portal 2 - Education Version]] [[Puzzle Creator]]. It has adjustable mass, friction and elasticity. The minimum mass is 1kg, maximum mass is  85kg. There are 5 levels for friction: frictionless, slippery, normal, sticky and very sticky.  There are also 5 levels for elasticity: no rebound, slight rebound, normal, bouncy, very bouncy. The default feature is 40kg, frictionless and no rebound. Different feature will have different outlook.&lt;br /&gt;
{{Clr}}&lt;br /&gt;

&lt;br /&gt;
{{spoiler|&#039;&#039;&#039;Frankenturrets&#039;&#039;&#039; are bizarre [[Turrets#Sentry Turret|Sentry Turret]]-[[#Weighted Storage Cube|Weighted Storage Cube]] hybrids created by [[Wheatley]] in order to complete test chambers when he had no test subjects. They are present in the single-player chapters, &#039;&#039;The Itch&#039;&#039; and &#039;&#039;The Part Where He Kills You&#039;&#039;.}}&lt;br /&gt;
&lt;br /&gt;
{{spoiler|Frankenturrets do not speak, and instead emits incomprehensible chirping sounds. They act as Wheatley&#039;s replacement for Storage Cubes, their only difference being that Frankenturrets will hop around aimlessly while not placed on a button. When picked up by [[Chell]], they retract their legs inside their cubes. If they fall over on their sides or upside down, they will wave their legs trying to get up.}}&lt;br /&gt;

== Receptacles ==&lt;br /&gt;
=== Heavy Duty Super Button ===&lt;br /&gt;
[[File:Portal 2 Heavy Duty Super-Colliding Super Button.png|left|100px]]&lt;br /&gt;
{{Main|Heavy Duty Super-Colliding Super Button|l1=Super Button}}&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;&#039;Heavy Duty Super Button&#039;&#039;&#039; is a receptacle that can be triggered by the weights of player characters, [[#Weighted Storage Cube|Weighted Storage Cube]]s, [[#Edgeless Safety Cube|Edgeless Safety Cube]]s, and [[#Frankenturret|Frankenturret]]s. The button was introduced in &#039;&#039;Portal&#039;&#039; and remained prevalent in &#039;&#039;Portal 2&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
An older prototype variant from the 50-70s era of the Super Buttons can be seen in the &#039;&#039;Portal 2&#039;&#039; single-player chapters &#039;&#039;The Fall&#039;&#039; and &#039;&#039;The Reunion&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
=== Weighted Storage Cube Receptacle ===&lt;br /&gt;
[[File:Weighted Storage Cube Receptacle.png|right|100px]]&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Weighted Storage Cube Receptacles&#039;&#039;&#039;, as obvious by its name, serves as a receptacle only for the [[#Weighted Storage Cube|Weighted Storage Cube]]s. This receptacle is only present in the co-op campaign of &#039;&#039;Portal 2&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
The Storage Cube must be placed securely inside the receptacle in order for test subjects to proceed. Although its appearance is similar to the [[Heavy Duty Super-Colliding Super Button|Super Button]], it cannot be activated by the weight of test subjects or any other objects being placed upon it.&lt;br /&gt;
{{Clr}}&lt;br /&gt;

[[File:Edgeless Safety Cube Receptacle.png|left|100px]]&lt;br /&gt;
{{Main|Edgeless Safety Cube Receptacle}}&lt;br /&gt;
The Edgeless Safety Cube Receptacle is a receptacle for the [[#Edgeless Safety Cube|Edgeless Safety Cube]], introduced in &#039;&#039;Portal 2&#039;&#039;. The Cube must be placed securely inside the receptacle in order for the player to proceed.&lt;br /&gt;
&lt;br /&gt;
Edgeless Safety Cubes and their receptacles only appear as testing elements in the game&#039;s cooperative campaign.&lt;br /&gt;

&lt;br /&gt;
=== Contraption Cube Receptacle ===&lt;br /&gt;
[[File:Contraption_Cube_Receptacle.png|right|150px]]&lt;br /&gt;
&lt;br /&gt;
The Contraption Cube Receptacle is exclusively featured in the [[Portal 2 - Education Version|educational version of Portal 2]]. Even though it is designed for the [[Cube#Contraption Cube|Contraption Cube]], the Receptacle will not recognize the Contraption Cube and won&#039;t activate any puzzle elements which are connected with it. Additionally, it appears entirely black in-game, when the model itself has different colors.&lt;br /&gt;

&#039;&#039;&#039;&#039;&#039;Portal&#039;&#039;&#039;&#039;&#039; is the original game of the &#039;&#039;Portal&#039;&#039; series.  It is a single-player puzzle-based video game developed by [[Valve]] and released as part of [[The Orange Box]] on October 9, 2007 for Microsoft Windows and Xbox 360; the PlayStation 3 version released at the later date of December 11, 2007.  &#039;&#039;Portal&#039;&#039; was also re-released as part of the launch of Mac OS X support for Steam on May 12, 2010; to celebrate it was given away for free until May 24, 2010 to Steam users on a promotional page on the Steam website. Further to this, Portal has been made available for free again for a limited duration as part of the [[Learn With Portals]] project in 2011.&lt;br /&gt;
&lt;br /&gt;
== Synopsis ==&lt;br /&gt;
{{main|Story}}&lt;br /&gt;
{{spoiler text|Portal&#039;s plot is revealed to the player via audio messages from [[GLaDOS]] and side rooms found in the later levels. According to The Final Hours of [[Portal 2]], the year is established to be &amp;quot;somewhere in 2010&amp;quot; — twelve years after its abandonment. The game begins with protagonist [[Chell]] waking up from a stasis bed and hearing instructions and warnings from GLaDOS about the upcoming test experience. This part of the game involves distinct test chambers that, in sequence, introduce players to the game&#039;s mechanics. GLaDOS&#039;s announcements serve not only to instruct Chell and help her progress through the game, but also to create atmosphere and develop the AI as a character. Chell is promised cake and grief counseling as her reward if she manages to complete all the test chambers.}}&lt;br /&gt;
&lt;br /&gt;
{{spoiler text|Chell proceeds through the empty Enrichment Center, interacting only with GLaDOS. Over the course of the game, GLaDOS&#039;s motives are hinted to be more sinister than her helpful demeanor suggests. Although she is designed to appear helpful and encouraging, GLaDOS&#039;s actions and speech suggest insincerity and callous disregard for the safety and well-being of the test subjects. The test chambers become increasingly dangerous as Chell proceeds, and GLaDOS even directs Chell through a live-fire course designed for military androids as a result of &amp;quot;mandatory scheduled maintenance&amp;quot; in the regular test chamber. In another chamber, GLaDOS boasts about the fidelity and importance of the Weighted Companion Cube, a waist-high crate with a single large pink heart on each face, for helping Chell to complete the chamber. However, GLaDOS then declares that it &amp;quot;unfortunately must be euthanized&amp;quot; in an &amp;quot;emergency intelligence incinerator&amp;quot; before Chell can continue. Some of the later chambers include automated turrets with child-like voices that fire at Chell, only to sympathize with her after being disabled (&amp;quot;I don&#039;t blame you&amp;quot; and &amp;quot;No hard feelings&amp;quot;). }}&lt;br /&gt;
&lt;br /&gt;
{{spoiler text|After Chell completes the final test chamber, GLaDOS congratulates her and prepares her &amp;quot;victory candescence&amp;quot;, maneuvering Chell into a pit of fire. As GLaDOS assures her that &amp;quot;all Aperture technologies remain safely operational up to 4,000 degrees [sic] kelvin&amp;quot;, Chell escapes with the use of the portal gun and makes her way through the maintenance areas within the Enrichment Center. Throughout this section, GLaDOS still sends messages to Chell and it becomes clear that she has become corrupt and may have killed everyone else in the center. Chell makes her way through the maintenance areas and empty office spaces behind the chambers, sometimes following graffiti messages which point in the right direction. These backstage areas, which are in an extremely dilapidated state, stand in stark contrast to the pristine test chambers. The graffiti includes statements such as &amp;quot;the cake is a lie&amp;quot; and pastiches of Emily Dickinson&#039;s poem &amp;quot;The Chariot,&amp;quot; Henry Wadsworth Longfellow&#039;s &amp;quot;The Reaper and the Flowers,&amp;quot; and Emily Brontë&#039;s &amp;quot;No Coward Soul Is Mine,&amp;quot; mourning the death of the Companion Cube.&lt;br /&gt;
GLaDOS attempts to dissuade Chell with threats of physical harm and misleading statements claiming that she is going the wrong way as Chell makes her way deeper into the maintenance areas. Eventually, Chell reaches a large chamber where GLaDOS&#039;s hardware hangs overhead. GLaDOS continues to plead with Chell, but during the exchange one of GLaDOS&#039; personality core spheres falls off; Chell drops it in an incinerator. GLaDOS reveals that Chell has just destroyed the morality core, which the Aperture Science employees allegedly installed after GLaDOS flooded the enrichment center with a deadly neurotoxin, and goes on to state that now there is nothing to prevent her from doing so once again. A six-minute countdown starts as Chell dislodges and incinerates more pieces of GLaDOS, while GLaDOS attempts to discourage her both verbally with a series of taunts and increasingly juvenile insults and physically by firing rockets at Chell. After she has destroyed the final piece, a portal malfunction tears the room apart and transports everything to the surface. Chell is then seen lying outside the facility&#039;s gates amid the remains of GLaDOS. One of the final scenes is changed through a patch of the PC version that was made available a few days before Portal 2&#039;s announcement; in this retroactive continuity, Chell is dragged away from the scene by an unseen entity speaking in a robotic voice, thanking her for assuming the party escort submission position (a reference to GLaDOS&#039;s request that she assume this position after escaping).&lt;br /&gt;
The final scene, after a long and speedy zoom through the bowels of the facility, shows a mix of shelves surrounding a Black Forest cake and the Weighted Companion Cube. The shelves contain dozens of other personality cores, some of which begin to light up before a robotic arm descends and extinguishes the candle on the cake. As the credits roll, GLaDOS delivers a concluding report: the song &amp;quot;Still Alive&amp;quot;, considering the experiment to be a huge success.}}&lt;br /&gt;
&lt;br /&gt;
== Development ==&lt;br /&gt;
Portal is Valve&#039;s professionally-developed spiritual successor to the freeware Narbacular Drop, the 2005 independent game released by students of the DigiPen; the original Drop team were employed at Valve. Certain elements, like the orange/blue system of identifying the two different portal ends a player can have open at a time (one connecting to the other), have been retained. The key difference in the signature portal mechanic between the two games is that in Narbacular Drop the player can place a portal on a wall visible through another portal, whereas in Portal, the HPD cannot fire a portal shot through a portal; however, the HPD can fire a portal shot while the player is standing in a portal.&lt;br /&gt;
