This [[Test Chamber]] is the nineteenth level of the game, and requires the player to utilize their knowledge of advanced [[Flinging]] techniques, momentum, [[High Energy Pellet]]s and [[Weighted Storage Cube]]s in order to proceed. [[Turrets]] are also present as an additional hazard.

== Hazards ==
* [[High Energy Pellet]]s
* [[Weighted Storage Cube|Cube Hazard]]
* [[Goo]]
* [[Turrets]]

== Walkthrough ==
{{Spoiler|block=yes|
*Walk to the end of the hallway. Turn around and fire a portal on the third panel above the hallway.
*Go back in the hall and the shoot a portal on the floor at the end of the hallway. Drop down through the portal.
*You should automatically drop through for the second time and then land on the other side of the Goo.
*Turn right and place a portal on the ceiling. Put the other portal on the wall above the goo and jump through it.
*Turn to face the platform above. Shoot a portal on the ceiling above it and the other one under yourself.
*Turn towards the door. Fire a portal on the same wall and put the other one near yourself and go through.
*Place a portal on the extended wallpanels near the ceiling. Shoot the other one on a platform below and jump through it.
*Walk to the [[switch]] and push it. Crouch and get to the second part of the chamber. Go to the left.
*Follow the aiming beam of the turret on the platform near you. Shoot a portal on the wall where the beam ends and the other one where the High Energy Pellet emitter is going to shoot next. Wait for the Pellet to knock the turret over.
*Do the same again for the turret aiming at the same wall and to the turret near you.
*At the back of the chamber there are extended walls facing the last turret. Put a portal there and the other one where the emitter is going to shoot next.
*You should have deactivated all of the four turrets. Go stand next to the switch and fire a portal on the extended walls on the other side of the chamber.
*Shoot a portal on the wall where the emitter is about to fire the next Pellet and wait for the Pellet to go through the portal.
*Quickly fire a portal on the wallpanels facing the switch and the other one on the wall near you. Enter through the portal and press the switch.
*Wait for the Pellet to reach the catcher and walk to the [[Unstationary Scaffold]].
*Get on the platform and wait for it to stop at the other end. Then drop down behind the switch.
*Shoot a portal above the glass on the other side and the other one on the wall next to you.
*Push the switch and go through the portal. When the panels are in the correct angle, put a portal on the panels and then turn left and go to the ledge.
*Shoot the other portal on the floor below and drop down through the portal.
*Pick up the [[Weighted Storage Cube|cube]] and wait for the Unstationary Scaffold to get near you. Then jump on the platform with the cube.
*Place the cube in front of the glass and place a portal above the glass. Turn around and go on the platform.
*Jump behind the switch again and put a portal on the wall.
*Push the switch and go through the portal. Pick up the cube and walk over to the first part of the chamber.
*Place the cube on the [[Heavy Duty Super-Colliding Super Button|button]] and fire a portal on the wall with the open door.
*Drop down on one of the platforms and fire a portal on the floor. Go through the portal.
*Go through the open door behind you and walk to the other end of the corridor and drop down.
*Shoot a portal on the platform further away. Turn to the left and fire the other portal on the floor there and drop down.
*When you have gone through the portal and are about to fall down again, place a portal on the platform beside you and go through the portal again.
*Do this two more times. You should then see angled panels somewhere. Shoot the portal there and you will reach the [[elevator]].

=== Alternative Solutions ===
{{Spoiler|block=yes|
Instead of activating the scaffold by directing the pellet into the catcher, you can simply fling yourself over to the cube if you're fast. When you step out into the room after deactivating all the turrets, immediately turn around and shoot a portal on the slanted platform, then jump down the ledge and shoot the other portal under you. You will fly and land in the room with the cube. At this point, the scaffold will activate without using the pellet at all.

A glitched way to complete the test is to retrieve the camera from the turret room and place it against the door, bypassing the need to get the cube as the camera holds the door open}}

Neurotoxin

2020-12-10T23:42:55Z

Luigi Main: added a peice of trivia

[[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 one section in either game where a [[portal]] can be moved on a surface is in the neurotoxin storgage room, where a portal is used to burn the tubes that dispense neurotoxin off via [[Thermal Discouragement Beam]]

Sentry Turret

2020-12-10T22:10:29Z

Luigi Main: It said you can only kill a turret via repulsion gel in the perpetual testing, there is multiple times in the main game where you cover them in the blue pudding.

[[File:Portal2_Turret_Standard.png|right|240px|Sentry Turret]]
{{Quotation|'''''GLaDOS''''', to '''''Chell'''''|"This next test involves turrets. You remember them, right? They're the pale, spherical things that are full of bullets. Oh wait, that's you in five seconds. Good luck."|sound = GLaDOS_turret_intro01.wav}}
'''Sentry Turrets''' are tripod robots that appear in every game in the ''Portal'' series. They are seen as incapable of independent movement, but can open each side of their chassis (their 'arms') horizontally in order to reveal two gatling guns. The central part of the chassis holds their red eye, which emits a targeting laser. Almost all of the space within the Turret is devoted to storing the ridiculously stacked ammo, explaining the nearly infinite supply of ammo when firing.

When test subjects are out of sight from the [[Turret]]'s presence, they will maintain a standby state and will remain motionless with their guns retracted. Moving into their angle of sight however, will cause Turrets to deploy their guns shortly after greeting the unlucky individual before opening fire. They will continue to fire until the target is dead or moves out of sight. If the latter occurs, Turrets will briefly search for the test subject (as indicated by the movement of the targeting laser), after which they will revert to a standby state.

[[Turret]]s can be avoided, disabled or destroyed in a number of ways. The most common method is knocking them over, causing them to flail and fire wildly before deactivating. This can be done by picking them up and dropping them, or using any object to tip them over. Additionally, the [[Thermal Discouragement Beam|Discouragement Beams]] or [[Material Emancipation Grill|Emancipation Grill]]s can be used to completely destroy them.

In ''[[Portal]]'', [[Turret]]s will shoot the glass when the player is on the other side. In ''[[Portal 2]]'', however, Turrets will only follow the player behind glass.

The Sentry Turrets are voiced by opera singer and voice actress {{W|Ellen McLain}}.

== Overview ==
*The Aperture Sentry Turret has a single red eye, sleek appearance, and predominately white color scheme common to most [[Aperture Science]] technology. Sentry Turrets are commonly seen serving as (rather ineffective) guards in the maintenance areas of the Enrichment Center, and during testing as an obstacle to the Test Subject.

*Sentry Turrets often speak in a sweet child-like, artificial voice similar to [[GLaDOS]] and a lavatory bowl within the Enrichment Center. They have a strangely polite demeanor, which is in direct contrast with their deadly behavior. They will even forgive [[Chell]] for knocking them over, suggesting they do not want to kill [[Chell]]. In one scene in [[Portal 2]], an [[Oracle Turret]] is seen stuck inside the Aperture Science Pipe Network, who attempts to get [[Chell]] and [[Wheatley]]'s attention. At [[Wheatley]]'s encouragement, [[Chell]] ignores it, but the Sentry Turret politely says "thanks anyway" with a hint of shattered hopes. It can later be seen and picked up in the incinerator room.

*The Sentry Turrets are armed with two dual machine guns, which can only be armed once a target comes within visual sight. Upon visual acquisition of the target, the Sentry Turret will come to full alert, and the machine guns will emerge. They will begin to fire at any visible targets (usually Test Subjects or intruders). When no targets are in visual range, the Sentry will scan the area in a sweeping motion with its laser targeting beam. Upon seeing that there are no more targets, the Sentry Turret will return to sleep mode after three seconds. These weapons, the machine guns, along with its antenna are normally hidden inside the body, during the Turret's "sleep mode".

*When passed through the material emancipation grill, they will emit a loud and long "oowowowowow" sound as it disintegrates, even if deactivated, suggesting they are only put in sleep mode when knocked over. The machine gun panels also close together in an erattic position if the turret is vaporised active.

*Aperture-Brand Resolution Pellets, the bullets for a Sentry Turret's guns, are simply dumped into its hollow body, called the Shell Redistribution Chamber; this allows for an unusually large supply of ammunition for such a small device. Aperture-Brand Resolution Pellets are the only type of ammunition that is recommended for use with a Sentry Turret. In addition, bullets are not "fired" in the traditional sense. They are propelled, shell and all, with a spring-loaded mechanism called the Projectile Acceleration Cylinder, which is guarded by the Aperture Turret External Barrel.

*The [[Personality Core]] of the Sentry Turret is located within the outer shell, right above the guns. It is fitted with a Fire/No Fire Incident Resolution Chip, presumably to help the [[Turret]] distinguish when or when not to fire, an Empathy Generator and an Empathy Suppressor. Apparently, the Empathy Suppressor is of greater influence, as simply standing near a Sentry Turret may cause its Empathy Suppressor to accidentally activate, greatly reducing the Sentry Turret's feelings of empathy toward its foe.

*The consumer version of the Sentry Turret is available in hundreds of different designer patterns and colors, including "Forest", "Desert", "Table", "Evening at the Improv", and "What Idiot Picked This?" (the latter three schemes being humorously named by Cave Johnson).

*Detailed in a ''[[Portal]]'' comic strip, the inception of the Sentry's strange disposition for singing and using melodious tones came from [[Aperture Science]] consumer product testers using the weapon as a possible use for protecting children from criminals. The test is a success but the baby begins to cry every time so they decide to include soft tones and lullabies. The second test is then deemed a success with the sleeping child.

== Tactics ==
*Sentry Turrets, when idle, conceal their weapons under the two plates on either side of their body. When they spot a target it takes a moment to deploy its weapons to fire. A Sentry Turret's weapons are very powerful and are able to kill a human, such as [[Chell]], after a few seconds of continuous fire. [[Atlas]] and [[P-body]], while sturdier than a human, still cannot endure lengthy sustained fire before falling apart. However, Sentry Turrets can be easily spotted by the visible laser beam emitted from their eye at all times, making it easier to avoid them. When knocked over Sentry Turrets fire frantically in all directions before permanently deactivating. Like all other objects within the Enrichment Center, the Sentry Turret will disintegrate (and produce an unusual sound) if it passes through a Material Emancipation Grill.

*In ''[[Portal]]'', the primary method of defeating the [[Turret]] is to disable it via knocking it over (echoing the method used in ''Half-Life 2''). This can be accomplished in various ways: by picking it up from behind and dropping it in an odd position, knocking it over with a weighted cube, hitting it with another object (including another turret), shooting a portal at its feet, or directing a [[High Energy Pellet]] into it (the Pellet will not destroy the turret on impact, but it will impart enough force to knock it over). [[Weighted Storage Cube|Weighted Storage Cubes]] are also bulletproof, and one can crouch behind them to be safe from their gunfire. They can also be destroyed by doing the same thing with a turret, however, this is difficult to do as the turret’s bullet spread is wider than a turret.

*''[[Portal 2]]'' introduces two new means for the player to disable the Turrets. One is to direct a [[Thermal Discouragement Beam]] onto it (usually via a portal and/or Weighted Pivot Cube), causing it to heat up and explode. Another is to cover it in [[Repulsion Gel]] causing it to bounce with increasing force until it either disables in midair, falls into the path of a [[Thermal Discouragement Beam]] or falls away into goo or a bottomless pit. [[Propulsion Gel]] makes a Turret quite slippery, making knocking it over easier, as it may lose its balance or knock against a wall.

== Trivia ==
[[File:Turret Boxed.png|right|thumb|Sentry Turret packaging|140px]]
*In contrast to ''[[Portal]]'', ''[[Portal 2]]'' Sentry Turrets will not attempt to shoot at enemies if glass is between them, although will still track the enemy with the laser pointer (They will, however, shoot at the player when 2 panes are between them and the player in some circumstances). A [[Hard Light Bridge]] will prevent the [[Turret]] from even detecting the enemy, making it go to sleep.

*During ''Portal 2'''s chapter ''The Escape'', [[Chell]] passes through the production line for the commercial version of the Aperture Science Sentry Turret. The developer commentary states that originally, they would have had the Sentry Turret built and boxed, then passed into a machine directly below. This machine would unbox and disassemble it, then recycling the parts, meaning that the Sentry Turrets are never actually shipped. They also would have included a massive pile of all the unrecycled packaging material, giving Aperture the most inefficient recycling system possible.

*Some of the Sentry Turret's sounds were not used in the game, but can be found in Portal's Game Cache File, including "Hello" from ''Portal 2'' teaser trailer and "Your business is appreciated," played when flushing the lavatory bowl in the Relaxation Vault.

*Sentry Turrets will fire at rockets fired from a Rocket Sentry. This is not seen in-game, as they normally never encounter each other.

*''Portal 2'' features numerous [[Defective Turret]]s, either missing their casings or assembled incorrectly.

*The Sentry Turrets are powered by a compact fusion core. It can be seen on the caseless Defective Turrets, on their back.

*The turret box states that one of the blue turrets was bought on January 25, 2010 by a person with an unreadable name. The reference to Michael Jackson can be seen on the posters.

*In ''Portal 2'', turret boxes indicated that turrets inside are blue. However, the machines in Turret Manufacturing build and box white turrets.

*Though [[Frankenturret]]s are able to move about with their legs, normal [[Turret]]s do not seem to be able to. This would indicate a usage modification which ultimately failed on [[Wheatley]]'s part. However, turrets are able to fold their legs inside of themselves for storage. Frankenturrets, lacking the back leg, might be attempting this motion in a way that would drag themselves forward.

*In ''Portal'', turrets will stay in the position they were picked up in when held (i.e. picking up a turret upside-down would make you keep holding it that way). In ''Portal 2'' they automatically rotate to upright and facing away from the player.

*When turrets are knocked over, they spin around wildly firing in all directions, this will cause them to deactivate themselves. If you can pick them up quick enough they won't deactivate.

*Despite the fact that the bullets fired from the [[Aperture Science]] Turret are propelled using a spring, the guns produce a muzzle flash and a noise; this is unusual considering that there is no gunpowder, or explosive propellant being used.

*In the Turret commercial, Cave Johnson says that the bullets are rammed into the Turret to have maximum functionality.

*When [[GLaDOS]] attempts to kill Wheatley with a paradox in the beginning of Chapter 8: The Itch, every Frankenturret is fried, humorously implying that they are smarter than Wheatley.

*Pointing a turret at a Wheatley monitor will cause the turret to shoot at Wheatley's image, therefore implying they see him as a threat.

*Turrets have been seen to be female, as an unused turret line states "I never liked ''her'' anyway."

* The Sentry Turret appears alongside several other ''Portal 2'' characters in the ''Portal 2 Level Pack'' for [[LEGO Dimensions]].

* In ''Portal 2'', Sentry Turret gibs (when exploded with the Thermal Discouragement Beam) appear to use the ''Portal'' textures, as the eye's texture looks vastly unlike the ''Portal 2'' striped version.

Thermal Discouragement Beam

2020-12-08T17:19:15Z

Luigi Main: I added the fact that the Thermal Discouragement Beam was a replacement for the High Energy Pellet

[[File:Thermal Discouragement Beam.png|thumb|300px|A Thermal Discouragement Beam]]

{{Quotation|'''Turret'''|sound=Turret turretshotbylaser04.wav|It burns!}}
The '''Thermal Discouragement Beam''' (referred by [[GLaDOS]] as "'''deadly laser''',") is a Test Chamber [[Mechanics|mechanic]] introduced in ''[[Portal 2]]''.

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.

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.

The beam is a replacement for the [[High Energy Pellet]] from [[Portal]] as in the first test chamber in which you see it (a copy of [[Portal Test Chamber 06]]) an emitter of the pellet is replaced by an emitter for the Beam. The two can both: Destroy turrets,activate elements, and have the direction that they are moving in shifted.
