This suggests that the Oracle Turret was one of the original sentry turrets seen behind Rattmann in the Aperture laboratory where he was working on the Portal Gun. ' It won't be enough.': Referencing Doug Rattmann in Portal 2: Lab Rat when observing the morality core intended for GLaDOS.Tartarus is the underworld in Ancient Greek myth, which was ruled over by Hades relating back to the oracle turret's statement of Greek myth. In fact, if one stands on the platform directly outside the abandoned sector's entrance, a massive steel pillar can be seen with the words 'Tartaros 09' painted on it. He was cast into the bowels of the Earth and pecked by birds.': The oracle turret refers to GLaDOS as 'Prometheus', who is trapped in a potato by Wheatley and thrown into the abandoned sector of the Aperture Science Innovators laboratories. ' Prometheus was punished by the gods for giving the gift of knowledge to man.' Don't make lemonade!': Another reference to the same recording.' Get mad!': A reference to Cave Johnson's raging intercom speech after his bankruptcy.Once saved, the Oracle Turret cannot accompany the player since the player must pass through an Emancipation Grill before continuing. Some of these phrases reference Cave Johnson's 'Don't Make Lemonade' speech and mentions Johnson's secretary and assistant, Caroline. When Chell chooses to save it from 'redemption', the Turret spouts a variety of cryptic phrases, in a similar vein to the All-Knowing Vortigaunt from Half-Life 2. The Turret, now referred to as the Oracle Turret for its wisdom, is seen for the last time in the chapter The Escape, where it is seen heading towards incineration (referred to as 'redemption' by the Announcer) on a conveyor belt consisting of broken Turrets, as seen in the Turret Manufacturing department. There is no way to get the turret out of the pipes, even if Chell continues to focus on it. This neglect finally causes the Turret to mention 'I'm different.' as the two abandon it. The Turret, desperate to be saved from the tube, tries to alert Chell for help by asking 'Hello?', however Wheatley directs Chell to divert her attention away from the Turret and generally neglecting it. The aforementioned tube is layered beside a catwalk leading to a hallway nearing the ruined Central AI Chamber. This Turret made its first appearance during The Courtesy Call chapter, in which it has been seen by Chell and a newly-disengaged Wheatley, lying in a powerless Aperture Science Pipe Network for many years since the Enrichment Center's destruction.
