Oracle 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.

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 the player to help it, and to take it with her; however the Oracle Turret is inaccessible and Wheatley instructs the player 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 is says "Thank you" and an achievement is unlocked for saving it.

If the player ignores it, the Oracle Turret will reach the end of the Redemption Line and disappear, presumaly being incinerated and destroyed.
