'''Defective Turrets''', or '''Crap Turrets''' as they are referred to by Wheatley, are damaged, unfinished, or faultily assembled Aperture Science Sentry Turrets seen and used in the Aperture Science Enrichment Center|Enrichment Center during the events of ''Portal 2''.
==Overview==
*They lack the outer white shell of normal turrets, and their insides are visible. Additionally, their laser guide is off or broken, and their dialogue indicates they are blind, though they seem to notice Chell regardless. They also seem to be out of bullets, as when they fire, only a clicking sound is made. After a while, they bizarrely catch on fire and explode. Some even appear to have been assembled sideways, or are still in their boxes.
*In Portal 2 storyline|Chapter 5 of ''Portal 2'', Chell sabotages the Aperture Science turret assembly lines by replacing the template turret with a defective one, causing all the fully functional turrets to be thrown out. This does not prevent fully-functional turrets from Turret Opera|appearing later, so it's possible this problem was later rectified or did not affect the turrets which had already been built. It could also be that Wheatley shut off the template altogether, meaning that the system randomly chose which ones were used and which ones were tossed, since he probably lacked the intelligence needed to make the simple fix.
*When GLaDOS attempts to surround Chell with turrets, she instead uses these because of the earlier sabotage. They simply stand around and click, then explode.
*Wheatley later repeats this error when he plans a perfectly good ambush for Chell, but uses defective turrets instead of working ones, despite knowing of Chell's sabotage (although he may have decided to let the system choose randomly to determine which ones were functioning, as mentioned before, explaining why he made this obvious mistake). They simply stand around idle while Wheatley repeatedly asks Chell whether she is dead or not.
*They speak in a masculine voice rather than the feminine ones like the rest of the turrets. Their voices also seem to lack the robotic edge of the normal turrets.
*They sometimes will ask other turrets for bullets, try to speak in a higher voice to imitate non-defective ones, and humorously shout "Blam! Blam! Blam! I'm not defective!" in a vain attempt to not get tossed out.
*Certain defective turrets are in boxes. They do not shoot and blow up near instantly.
==Trivia==
FileTurret backwards.jpg|200px|thumb|Another type of defective Turret.
*These are not to be confused with the Oracle Turret|"different" turret, which is fully assembled but says different lines in a different voice.
*If the player grabs one before moving the template turret and switches them instantaneously, the template turret exploding will cause the defective turret to become slightly misaligned. Despite this, the system still functions correctly.
*Strangely, there seems to be many exact copies of the defective turret as many of them pass through without getting discarded.
*The turrets appearing in Course 5 of Cooperative Testing Initiative look like defective turrets but work and speak properly. This, possibly, means that defective turrets are built by broken 20th century machines, as Course 5 is set in the old Aperture Science Enrichment Center|Enrichment Center.
*Hacking a functioning turret into the game and placing it in the Master Turret Booth will cause it to change its model to a defective turret.{{YouTube|CKB6sfTProg|Portal 2 - Prometheus Turret On Production Line}}
*If the player brings two defective turrets into the turret control room before replacing the template, then they can take one of the defective turrets with them. However, due to the Portal 2 engine the turret will despawn when you hit the loading screen to go to the Neurotoxin generator. This is one of the few cases in the game where the player can make a forced despawn of an object happen, as usually Material emancipation grills would destroy any objects immediately before a transition point.
*It seems there can only be up to 4 defective turrets on the catwalks in the Turret Manufacturing plant. Any more and the turrets start exploding in the order they were caught with every additional turret.
*In the end of the Co-op campaign, the turret guarding the vault uses neither the normal turret or defective turret dialogues. Instead, it blurts out "Save the Humans!" in an entirely different voice just before opening fire.
==Co-oP Levels==
* Please note that in the Co-oP levels where you save the humans they may look defective but they shoot fine (despite having no ammo container) and talk in their normal voice.
*The defective turret appears in the co-op main story credits.
