Defective Turret

Defective Turrets, or Crap Turrets as they are referred to by Wheatley, are damaged, unfinished, or faultily assembled turrets seen and used in Aperture Laboratories 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 and POTaDOS. 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.


 * In 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.


 * When GLaDOS attempts to surround Chell with turrets, she instead uses these because of the earlier sabotage. They simply stand around and click, and explode.


 * 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 humorously shout "Ummm... Blam! Blam! Blam! I'm not defective!" in a vain attempt to not get tossed out. They will also sometimes ask other turrets for bullets and pretend to be a regular turret so they don't get tossed out.

Trivia

 * These are not to be confused with the "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 slightly misaligned the defective one. Despite this, the system functions as it did.


 * The model for the defective turret is used in the final chamber of course 5 in the Cooperative Testing Initiative. Contrary to their appearance, however, the turrets are perfectly functional. They are merely reskinned normal turrets.
