Oracle Turret

"I'm different..."

- Oracle Turret

The Oracle Turret is a malfunctioning Aperture Science Sentry Turret that must be saved from its 'redemption' (incineration) line in order to gain the achievement 'No Hard Feelings'. When saved from redemption, the turret spouts a variety of cryptic phrases, in a similar vein to the All-Knowing Vortigaunt. Some of these phrases reference Cave Johnson's 'Don't Make Lemonade' speech and mention Johnson's secretary and assistant, Caroline. Once saved, the Oracle Turret cannot accompany the player since the player must pass through an Aperture Science Material Emancipation Grill before continuing.

A phrase from the Oracle Turret that details the legend of the Greek titan Prometheus, seems to reference several features about both GLaDOS and Aperture Science itself. It is possible that the Oracle Turret holds some part of Cave Johnson's personality as evidenced by its quoting Johnson's speeches.

Quotes
In the order said, once held:
 * "Get mad!"
 * "Don't make lemonade!"
 * "Prometheus was punished by the gods for giving the gift of knowledge to man. He was cast into the bowels of the Earth and pecked by birds."
 * "It won't be enough."
 * "The answer lies beneath us."
 * "Her name is Caroline. Remember that."
 * "That's all I can say."

It remains silent after this. However, whenever picked up, it will say:
 * "Thank you."

Trivia

 * It is first seen in the video "Aperture Investment Opportunity #3 - Turrets" in which it is described as "desert" color and uses the "I'm different" voice sample.
 * Its first in-game appearance is when touring the facility with a disengaged Wheatley, right before entering GLaDOS's chamber for the first time. It is stuck in a disengaged portion of the Aperture Science Pipe Network, saying "Hello?" and "I'm different...", while Wheatley tells you not to make eye contact or respond, and telling it that you're not stopping.
 * It says "I'm different..." again when seen lying on a turret redemption line.
 * It speaks in a higher and slightly more off-tune and breaking voice than regular turrets.
 * Its laser sight blinks. If you spin fast enough while holding it, it won't sync up and float a bit to the side of it.
 * One of the structures at the beginning of The Fall is labeled "Tartaros 09", referring to Tartarus, also in Greek mythology.
 * The names of the turret's sound files begin with "different turret".
 * The statement about Prometheus may in fact be a reference to GLaDOS, in that she gave Chell knowledge, then falls into the bowels of Aperture Science, and is later pecked by a bird.
 * It could alternately be interpreted as when Chell (and GLaDOS, inadvertently) gave Wheatley "knowledge" and power.
 * The phrase "The answer lies beneath us" is likely a reference to the old abandoned Aperture Science Innovators complex contained below the newer Aperture Laboratories and the crucial part that the pre-registered voice messages play in restoring GLaDOS' "conscience".
 * The phrase "It won't be enough." likely refers to Doug Rattmann's opinion that the Morality Core will not be enough to control GLaDOS.
 * It could also refer to Wheatley's itch for testing and how in the end it isn't enough to satisfy him.
 * It could also refer to the turret's memory capacity not being large enough to hold a complete copy of Cave Johnson's personality (the turret references portion's of Cave's speeches, "Get mad" and "Don't make lemonade", indicating that it may hold Cave Johnson). Cave may have originally been in GLaDOS but then transferred into the turret, as Cave had instructed his staff to do this: "Hell, put her (Caroline) in my computer. I don't care."
