&lt;br /&gt;
== Overview (no spoilers) ==&lt;br /&gt;
&lt;br /&gt;
When activated, a Portal Spawner will spawn a [[Portals|portal]] inside of it. Each spawner is set to spawn a particular color portal. Spawners are sometimes activated as soon as you enter the [[Test Chambers|test chamber]]. Other times, they are activated by [[Pedestal Button|Pedestal Buttons]] or set on a timer. In the very beginning of each game, when the player has no [[Handheld Portal Device]], both blue and orange Portal Spawners can be found in the test chambers. Once the player has the Single Portal Device and can fire blue portals on their own, only orange Portal Spawners appear. When they have the Dual Portal Device, Portal Spawners (now irrelevant), disappear altogether.&lt;br /&gt;
&lt;br /&gt;
== Trivia ==&lt;br /&gt;
* An icon of a Portal Spawner can be found in the [[Puzzle Creator]]&#039;s files, despite it not being in the Puzzle Creator.&lt;br /&gt;

[https://www.digipen.edu/fileadmin/website_data/gallery/game_websites/NarbacularDrop/ &#039;&#039;&#039;Narbacular Drop&#039;&#039;&#039;] is a puzzle video game developed by Nuclear Monkey Software, and is the spiritual predecessor to &#039;&#039;[[Portal]]&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
== Plot synopsis ==&lt;br /&gt;
A princess, called No-Knees due to her inability to jump, was admired by her entire kingdom. A demon, imagining that her kidnapping would help in his quest to conquer the world, captures No-Knees. He then locks her inside a cage in his mountain lair, under patrol of his Impy minion. However, Wally, the spirit of the mountain, was mad at the Demon for creating his dungeon lair inside his home. He tells No-Knees he would assist her in escaping as long as she helped him to defeat the demon. To escape, Princess No-Knees is allowed to use Wally&#039;s magical power; she can look at any two flat surfaces and break reality, making an instant link between them using two portals. She must then use this to travel through five different chambers all the way to the final boss.&lt;br /&gt;
&lt;br /&gt;
== Development ==&lt;br /&gt;
&#039;&#039;Narbacular Drop&#039;&#039;&amp;lt;nowiki&amp;gt;&#039;&amp;lt;/nowiki&amp;gt;s main focus was to use the portal system, a technical mechanic that had emerged in a few games by that time, as the key feature in a game.&amp;lt;ref&amp;gt;[https://www.digipen.edu/fileadmin/website_data/gallery/game_websites/NarbacularDrop/ Narbacular Drop Overview]&amp;lt;/ref&amp;gt; With the addition of allowing the player, as well as other objects, to go through the portal, the game includes a wide range of gameplay possibilities.&lt;br /&gt;
&lt;br /&gt;
The game development had 4 &amp;quot;milestones&amp;quot;: Pre-Alpha, Alpha, Beta, and Final.&amp;lt;ref&amp;gt;[https://www.digipen.edu/fileadmin/website_data/gallery/game_websites/NarbacularDrop/documents/narbacular_drop_milestones.pdf Narbacular Drop Milestone List (PDF)]&amp;lt;/ref&amp;gt; Each version included mostly fixes and level coding.&lt;br /&gt;
&lt;br /&gt;
The final version of the game includes the model, animations, and textures for the final boss, the Demon; however, the final battle was never properly implemented, and even though the final credits appear, the game never actually ends. Consequently, Wally does not show himself and Princess No-Knees never escapes the dungeon.&lt;br /&gt;
&lt;br /&gt;
Jeep Barnett, a developer of the game and current employee at [[Valve Corporation|Valve]], stated on the now-defunct forums of Narbacular Drop, that the final chapter of the game, &#039;&#039;Fire with Fire&#039;&#039;, &amp;quot;was a hint as to how to beat the final boss who would [throw] fire balls at you that you need to redirect through a portal.&amp;quot; &amp;lt;ref&amp;gt;[http://web.archive.org/web/20071212110322/http://www.nuclearmonkeysoftware.com/forums/index.php?topic=123.msg451#msg451 Nuclear Monkey Software forums, archived]&amp;lt;/ref&amp;gt; {{Spoiler|The concept behind redirecting an enemy&#039;s attack would return in the climatic battle of &#039;&#039;Portal&#039;&#039;, between [[Chell]] and [[GLaDOS]].}}&lt;br /&gt;

&lt;div&gt;[[Image:P-Body_Portals.png|350px|right|thumb|A curious [[P-body]] testing and playing with the Portal Gun.]]&lt;br /&gt;
{{Quotation|&#039;&#039;&#039;GLaDOS&#039;&#039;&#039;|Momentum, a function of mass and velocity, is conserved between portals. In layman&#039;s terms: Speedy-thing goes in, speedy-thing comes out.|sound=GLaDOS_06_part1_success_2-1.wav}}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Portals&#039;&#039;&#039; are the primary gameplay [[Mechanics|mechanic]] of the &#039;&#039;Portal&#039;&#039; 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.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
&lt;br /&gt;
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.&lt;br /&gt;
&lt;br /&gt;
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.&lt;br /&gt;
&lt;br /&gt;
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 &#039;&#039;[[Portal 2]]&#039;&#039;.}}&lt;br /&gt;
&lt;br /&gt;
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&lt;br /&gt;
&lt;br /&gt;
In &#039;&#039;[[Portal]]&#039;&#039; and the single-player campaign of &#039;&#039;[[Portal 2]]&#039;&#039;, protagonist and test subject [[Chell]] can create blue (primary) and orange (secondary) portals with her version of the Dual Portal Gun. In &#039;&#039;Portal 2&#039;&#039;&amp;lt;nowiki&amp;gt;&#039;&amp;lt;/nowiki&amp;gt;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.&lt;br /&gt;
&lt;br /&gt;
=== Pre-release designs ===&lt;br /&gt;
The portals have had several changes in design before the final release of &#039;&#039;Portal&#039;&#039; in October 10, 2007, as evident in some trailers and screenshots.&amp;lt;ref&amp;gt;[http://www.youtube.com/watch?v=TluRVBhmf8w portal orientation video 1] on YouTube.com&amp;lt;/ref&amp;gt; Even Earlier development screenshots from &#039;&#039;Portal&#039;&#039; 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]]&#039;s secondary-fire in &#039;&#039;Portal 2&#039;&#039;. At some point, the developers decided to maintain the blue and orange color schemes previously used as portals in &#039;&#039;[[Narbacular Drop]]&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
== Gameplay exploits==&lt;br /&gt;
* &#039;&#039;&#039;Reportalling&#039;&#039;&#039;: 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).&lt;br /&gt;
* &#039;&#039;&#039;Portal bumping&#039;&#039;&#039;: When placing a portal onto another portal, the other portal will get bumped to a position that is next to the first placed one. By using this glitch, players can skip some chambers in both games - [[Portal Test Chamber 16]] (just the first speech and the glass clip), [[Portal Test Chamber 17]] (all the way to the incinerator room), and in the second game the player can get into some observation rooms with this glitch (for example, the one in the first laser relay map).&lt;br /&gt;

At some point, the developers decided to maintain the blue and orange color schemes previously used as portals in &#039;&#039;[[Narbacular Drop]]&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
== Gameplay exploits==&lt;br /&gt;
* &#039;&#039;&#039;Reportalling&#039;&#039;&#039;: 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).&lt;br /&gt;
* &#039;&#039;&#039;Portal bumping&#039;&#039;&#039;: When placing a portal onto another portal, the other portal will get bumped to a position that is next to the first placed one. By using this glitch, players can skip some chambers in both games - [[Portal Test Chamber 16]] (just the first speech and the glass clip), [[Portal Test Chamber 17]] (all the way to the incinerator room), and in the second game the player can get into some observation rooms with this glitch (for example, the one in the first laser relay map).&lt;br /&gt;

This is the ninth level of the game, and takes place within a Test Chamber and the [[Incinerator]] Room. This level introduces the player to the dual-portal variant of the [[Aperture Science Handheld Portal Device]], and the way in which two linked player-created [[Portals]] can be used to avoid obstacles. This level advances the storyline, and does not contain any significant Portal-based puzzles or obstacles.

&lt;div&gt;[[File:Thermal Discouragement Beam.png|thumb|300px|A Thermal Discouragement Beam]]&lt;br /&gt;
&lt;br /&gt;
{{Quotation|&#039;&#039;&#039;Turret&#039;&#039;&#039;|sound=Turret turretshotbylaser04.wav|It burns!}}&lt;br /&gt;
The &#039;&#039;&#039;Thermal Discouragement Beam&#039;&#039;&#039; (referred to as the &amp;quot;&#039;&#039;&#039;deadly laser&#039;&#039;&#039;&amp;quot; by [[GLaDOS]],) is a Test Chamber [[Mechanics|mechanic]] introduced in &#039;&#039;[[Portal 2]]&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
The Beam is fired in a straight line from an immovable device built into the wall or ceiling of a Test Chamber. Each Beam is usually coupled with one Receptacle, though multiple Beams and/or multiple Receptacles may be present within a single Test Chamber. Directing the Beam into the Receptacle will activate certain mechanics that are crucial in reaching the chamber exit. The Beam can also be used in conjunction with Relays, which are small nodes built into the floor of some Test Chambers. Relays are activated when the Thermal Discouragement Beam passes through them, and multiple Relays must often be activated using a single Beam. Once all Relays are activated, specific Test Chamber mechanics will be triggered, similarly to the activation of a Receptacle.&lt;br /&gt;
&lt;br /&gt;
Thermal Discouragement Beams can be angled in certain directions with the use of the [[Discouragement Redirection Cube]] and [[portals]]. Additionally, the beam holds the ability to travel through transparent objects such as glass. They can also be used as a weapon, as they cause [[Turret]]s to heat up and violently explode. Touching the beam while on the ground will make a “sizzle” sound and push the player away, as well as deal a small amount of damage. Prolonged, repeated exposure to the Beam will result in death.&lt;br /&gt;
&lt;br /&gt;
The beam appears to be a replacement for the [[High Energy Pellet]] from [[Portal]] as in the first test chamber in which you see it (a copy of the original [[Portal Test Chamber 06]]) a destroyed pellet launcher is replaced by an emitter for the Beam. Additionally, the two can both destroy turrets, and activate dedicated receptacles.&lt;br /&gt;

&lt;div&gt;[[File:Thermal Discouragement Beam.png|thumb|300px|A Thermal Discouragement Beam]]&lt;br /&gt;
&lt;br /&gt;
{{Quotation|&#039;&#039;&#039;Turret&#039;&#039;&#039;|sound=Turret turretshotbylaser04.wav|It burns!}}&lt;br /&gt;
The &#039;&#039;&#039;Thermal Discouragement Beam&#039;&#039;&#039; (referred to by [[GLaDOS]] as &amp;quot;&#039;&#039;&#039;deadly laser&#039;&#039;&#039;,&amp;quot;) is a Test Chamber [[Mechanics|mechanic]] introduced in &#039;&#039;[[Portal 2]]&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
The Beam is fired in a straight line from an immovable device built into the wall or ceiling of a Test Chamber. Each Beam is usually coupled with one Receptacle, and multiple Beams with multiple Receptacles may be present within a single Test Chamber. Directing the Beam into the Receptacle will activate certain mechanics that are crucial in reaching the chamber exit. The Beam can also be used in conjunction with Relays, which are small nodes built into the floor of some Test Chambers. Relays are activated when the Thermal Discouragement Beam passes through them, and multiple Relays must often be activated using a single Beam. Once all Relays are activated, specific Test Chamber mechanics will be triggered, similarly to the activation of a Receptacle.&lt;br /&gt;
&lt;br /&gt;
Thermal Discouragement Beams can be angled in certain directions with the use of the [[Discouragement Redirection Cube]] and [[portals]]. Additionally, the beam holds the ability to travel through transparent objects such as glass. They can also be used as a weapon, as they cause [[Turret]]s, with their large ammunition loads, to heat up and explode. Touching the beam while on the ground will push the player away, as well as deal a small amount of damage. Prolonged exposure will result in death.&lt;br /&gt;
&lt;br /&gt;
The beam appears to be a replacement for the [[High Energy Pellet]] from [[Portal]] as in the first test chamber in which you see it (a copy of the original [[Portal Test Chamber 06]]) a destroyed pellet launcher is replaced by an emitter for the Beam. Additionally, the two can both destroy turrets, and activate dedicated receptacles.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{Stub|Needed: screenshots of it being used in-game redirected through portals, or used as shield, or as platform for gels}}&lt;br /&gt;
[[File:Hard-Light Bridge.png|right|300px|thumb|The Hard-Light Bridge as it appears in &#039;&#039;Portal 2&#039;&#039;.]]&lt;br /&gt;
{{Quotation|&#039;&#039;&#039;GLaDOS&#039;&#039;&#039;|These bridges are made from natural light that I pump in from the surface. If you rubbed your cheek on one, it would be like standing outside with the sun shining on your face. It would also set your hair on fire, so don&#039;t actually do it.|sound=GLaDOS_sp_a2_bridge_intro01.wav}}&lt;br /&gt;
&lt;br /&gt;
A &#039;&#039;&#039;Hard-Light Bridge&#039;&#039;&#039; (simply known as a &#039;&#039;&#039;Light Bridge&#039;&#039;&#039;,) is a semi-translucent solid made from natural sunlight beamed in from the Earth&#039;s surface. It can act as a bridge for the player, a shield against turrets and other hazards, or even a wall for more complex puzzles the player encounters later on. Light Bridges first appeared in the [[Portal: The Flash Version MapPack|Flash Version MapPack]] and then in [[Portal: Still Alive]], but were more formally introduced in [[Portal 2]]. The bridges span an infinite length or until stopped by another solid. Although the bridge is made of light, if one portion of the bridge is stopped by a solid object the rest will not continue as a beam of light normally would. Also, portals need to be in center with the bridge if trying to get it to another place, otherwise it won&#039;t pass through.&lt;br /&gt;
&lt;br /&gt;
Hard-Light Bridges can also be covered in [[Gels|Mobility Gels]], allowing the player to use the gels in places where it normally would just fall through. Gels placed on Hard-Light Bridges are not permanent and disappears the moment the bridge dissipates or moves to a different location. (This can only be seen in custom-made maps, as the Bridges and gels do not co-exist in the main Portal 2 game.)&lt;br /&gt;

== Trivia ==&lt;br /&gt;
* The Hard Light Bridge was originally referred to as &amp;quot;Blue Plasma Wall&amp;quot; in [[Portal: The Flash Version]]&lt;br /&gt;
* Despite GLaDOS warning the player that the Hard Light Bridge would [[Media:GLaDOS_sp_a2_bridge_intro01.wav|set their hair on fire if they rubbed their cheek on one]], rubbing any body part on the bridge actually does not cause any harm to the player.&lt;br /&gt;

[[File:Vital Apparatus Vent Portal 2.png|right|225px|thumb|A Vital Apparatus Vent in &#039;&#039;Portal 2&#039;&#039;.]]&lt;br /&gt;
{{Quotation|&#039;&#039;&#039;GLaDOS&#039;&#039;&#039;|The Vital Apparatus Vent will deliver a Weighted Companion Cube in three, two, one.|sound=GLaDOS 13_part1_entry-1.wav}}&lt;br /&gt;
The &#039;&#039;&#039;Vital Apparatus Vent&#039;&#039;&#039; (or more simply a “cube dropper”) is the final component in the [[Tubes|vacuum tube]] network that delivers testing apparatus when activated, either by buttons or automatic replenishing.&lt;br /&gt;
&lt;br /&gt;
In the &#039;&#039;Portal&#039;&#039; series, test subjects can shoot a portal underneath the cube dropper so that the dropped object&#039;s momentum may be used to launch it. In the event of the object delivered by the vent being destroyed in any way (incinerated, dropped in goo etc.), the vent will usually deliver a replacement. In most cases, when activated a second time the object previously delivered will be fizzled.&lt;br /&gt;
&lt;br /&gt;
Vital Apparatus Vents drop the following items throughout the &#039;&#039;Portal&#039;&#039; series, always cubes:&lt;br /&gt;
* [[Weighted Storage Cube]]&lt;br /&gt;
* [[Weighted Companion Cube]]&lt;br /&gt;
* [[Discouragement Redirection Cube]]&lt;br /&gt;
* [[Edgeless Safety Cube]]&lt;br /&gt;
