Cave Johnson: Cave Johnson here.
[An animated scene fades in where many turrets are dropped into view and activated.]
Cave Johnson: Introducing the consumer version of our most popular military grade product;
[Turrets chattering: "Hello?". The view zooms past the turrets as another turret fades in.]
Cave Johnson: The Turret.
[The turret is pulled apart in a cutaway, revealing many bullets stored inside.]
Cave Johnson: How do we get so many bullets in 'em? Like this.
[In a diagram on the side, bullets are poured into the middle of the cutaway turret, marked "Shell Redistribution Chamber". The turret parts begin to fall, leaving the side gun mechanism in place. Zoom in to a cutaway of the gun mechanism.]
Cave Johnson: Plus, we fire the whole bullet. That's 65% more bullet, per bullet.
[Cut to a pre-rendered scene. Three turrets guarding a co-op exit activate, and shoot at Atlas and P-body, who run away from the turrets.]
Cave Johnson: This is the same technology we've been using on robots for decades. Scares the hell out of them.
[A display is shown of different turret styles.]

Turret: I'm different.

[Static cut to a turret assembly machine. The turret retracts its gun arms and legs and is stored into a "Sentry Turret" box.]
Cave Johnson: Then we box 'em up, and ship 'em straight to your doorstep.
[The box falls into an animated diagram of a bedroom in front of a blue sky background. Upon landing, the box packaging breaks open, and the turret unfolds. Two stick figures, representing parents, are shown waving.]
Cave Johnson: So you can protect the things that matter most.
[The scene changes to nighttime, and the turret's red light turns on.]
Turret: Good night.
[The Portal 2 logo appears.]
Cave Johnson: Just try and get close to that baby. Hah! Your funeral. Cave Johnson. We're done here
