'''Portals''' are the primary gameplay [[Mechanics|mechanic]] of the ''Portal'' series. Portals can only be placed on white, stationary (except for one occasion in [[Portal 2|Portal 2]]), flat surfaces by an [[Aperture Science Handheld Portal Device]] (simply referred to as a Portal Gun), and works in pairs thereby allowing two-way movement through each portal.

== Overview ==

Portals in a pair act as a direct link between one another. Anything that goes into one portal comes instantly out the other. Objects going at high speed into a portal (such as falling into one from great height) will maintain their speed when coming out of the other, giving the player the ability to launch themselves or other objects through the air. Portals are also capable of continuing any sort of beam, specifically the [[Excursion Funnel]]s, [[Thermal Discouragement Beam]]s, and [[Hard Light Bridge]]s. If only one portal in a pair exists at the moment, the existing portal is an oval completely filled in with color. When attempting to enter an unpaired portal, it will act as a solid wall. When both portals in a pair exist, they will appear to be like windows. When looking through one portal, you can see directly out the other. When a portal is linked, you can identify which portal it is by looking at its colored border.

Once the player obtains the Portal Device, they can create a portal on a surface by aiming at the spot they want to put the portal and pressing the primary or secondary fire key. If the player has only acquired the Single Portal Device, both fire keys produce the primary portal color. If they have acquired the Dual Portal Device, the primary fire key produces the primary color and the secondary fire key produces the secondary color. Portals cannot be placed on surfaces that are not made of the appropriate material (white walls usually indicate this material), moving, not flat, or not large enough for a portal to fit onto it. Portals also cannot be placed while looking through currently existing portals.

Portals is very likely moving at the [[Wikipedia:Speed of light|speed of light]]{{Spoiler|, this is proved by the time to shoot a portal to the moon in the finale of ''[[Portal 2]]''.}}

Portals transmit matters and light, this is proved by {{Tooltip|Excursion Funnels, Thermal Discouragement Beams and Hard Light Bridges|GLaDOS claimed that these matters are made from pure light}} can pass through portals

In ''[[Portal]]'' and the single-player campaign of ''[[Portal 2]]'', protagonist and test subject [[Chell]] can create blue (primary) and orange (secondary) portals with her version of the Dual Portal Gun. In ''Portal 2''<nowiki>'</nowiki>s [[co-op]] campaign, each robot test subject possesses individual portal colors in order to differentiate them; [[Atlas]] creates cyan (primary) and indigo (secondary) portals, whereas [[P-body]] creates yellow (primary) and red (secondary) portals.

=== Pre-release designs ===
The portals have had several changes in design before the final release of ''Portal'' in October 10, 2007, as evident in some trailers and screenshots.<ref>[http://www.youtube.com/watch?v=TluRVBhmf8w portal orientation video 1] on YouTube.com</ref> Even Earlier development screenshots from ''Portal'' revealed that the original colors for the portals were light blue (primary-fire) and purple (secondary-fire), with the portals more resembling like rifts ripped into a dimension than the simpler oval designs in the current series. Later, the purple color was replaced with red, akin to [[P-Body]]'s secondary-fire in ''Portal 2''. At some point, the developers decided to maintain the blue and orange color schemes previously used as portals in ''[[Narbacular Drop]]''.

== Gameplay exploits==
* '''Reportalling''': With some movements, the player is able to boost their momentum when traveling through two portals placed on the floor by using their primary or secondary fire key as they exit the portal they are going through, respectively. This is caused by the portals giving a push to the player from a portal if the portal is re-placed somewhere else (or in this case, in the same place).

Neurotoxin

[[File:Neurotoxin Storage Tank Catwalk Front.png|thumb|300px|The Neurotoxin Production Facility's main storage tank]]
{{Quotation|''GLaDOS'''|sound=GLaDOS_jailbreak06.wav|Do you hear that? That's the sound of the neurotoxin emitters emitting neurotoxin.}}

'''Neurotoxin''', comically referred to as '''Deadly Neurotoxin''' by [[GLaDOS]], is a gaseous chemical agent that appears in ''[[Portal]]'' and in ''[[Portal 2]]'s'' single-player campaign. Manufactured in the Neurotoxin Production Facility, {{W|neurotoxin}} can be ventiled into any part of [[Aperture Science]] Enrichment Center and is pumped through a series of emitters.

== Overview ==
Neurotoxin is not an environmental hazard in the traditional sense of gameplay, as it only appears during specific, scripted events in the ''Portal'' series, mostly at the game's climax. In the ''[[Portal 2: Lab Rat|Lab Rat]]'' comic, it is confirmed that [[GLaDOS]] ventilated neurotoxin as a means of killing all [[Aperture Science]] personnel prior to [[Chell]]'s awakening in ''Portal'', and is frequently used as an attempt to kill her. {{spoiler|Later on in the single-player campaign of ''Portal 2'', Wheatley also attempts to kill [[Chell]] with it.}}

The entirety of these gases are stored and manufactured in a reinforced tank, located in the bowels of the Enrichment Center. Eight main hoses allow the gas to be transferred to any location within the facility. {{spoiler|During the chapter ''The Escape'', Chell sabotages the system by cutting the eight primary hoses, thereby destroying the generator.}}

The variety of neurotoxin used within the Aperture Science facilty is unusual in that a certain concentration is required before it becomes lethal. Until the saturation level has been reached, the gas is not lethal and is presumed to be merely toxic. {{Spoiler|It is this delay that provides Chell with the opportunity to defeat GLaDOS in ''Portal'' and later, Wheatley in ''Portal 2''.}}

==Trivia==
* Despite the [[Portal 2 Chapter 5 Neurotoxin Generator|neurotoxin generator]] being {{Spoiler|completely destroyed by Chell and Wheatley early on in the game, Wheatley is still able to use neurotoxin in the final battle.}}
* The [[Announcer]] is known to pronounce "neurotoxin" in two different ways: {{Spoiler|During the chapter ''The Escape'' and at the beginning of the final boss fight in "The Part Where He Kills You", he pronounces it as "ne-oo-rotoxin". However, later on in the same boss fight, he pronounces it way faster, as "nürotoxin"}}
* The Neurotoxin Storage room is the only room in both Portal and Portal 2 that allows the player to place portals on a moving surface, where a portal is used to burn the tubes that dispense neurotoxin off via [[Thermal Discouragement Beam]].
