Oracle Turret


 * Not to be confused with the Defective Turret or the Prima Donna Turret.



The Oracle Turret is a friendly Sentry Turret that is encountered twice in Portal 2. Although the Oracle Turret is never named in-game, the name was revealed in an interview with Valve writers.

Like GLaDOS and the standard Sentry Turrets, the Oracle Turret is voiced by opera singer and voice actress.

Chapter 1
The player first encounters the Oracle Turret in Chapter 1 of Portal 2, where the Oracle Turret is stuck in a pneumatic transport tube. The Oracle Turret asks Chell to help it, and to take it with her; however the Oracle Turret is inaccessible and Wheatley advises Chell to move past and ignore it.

Chapter 5
The second encounter with the Oracle Turret is on the Turret Redemption Line. The player can pick the turret up from the Turret Redemption Line, at which point it says "Thank you" and an achievement (No Hard Feelings) is unlocked for saving it. If the player ignores it, the Oracle Turret will complete its journey along the Redemption Line and disappear, and will presumably be incinerated and destroyed. The player later has the option of sending the turret through a Material Emancipation Grill.

This quotation is in reference to the Portal 2 graphic novel, Lab Rat during Page 14 wherein Doug Ratmann informs Henry that a Morality Core will not be enough to stop GLaDOS as one can always ignore their conscience.
