Turret factory

Now a turret's tale isn't quite as nice
As manufacture process that makes them fire twice
But a turret's easy once you get to know it
With the help of the magic of a ATR device

Let's delve deeper into Aperture's philosophy
Far beyond that of the cake mythology
It's easy to misjudge that massive underground testing city
With it's testing chambers and portal techology
But with all great things comes a great responsibility
That of Aperture's being product realibility
How, you ask, are they up to the task
To which the answer is in a simple facility

In the turret Factory, where turret fears and horrors come true
In the turret Factory, where not a single defective one gets through
