Cores and turrets of every stage
Wouldn't you like to escape this cage?

[Black Turrets]
Come to us and you'll be sure
You're not safe in Aperture

[White Turrets]
This is Aperture!
This is Aperture!

This is Aperture!
Everybody hit the floor
Take a seat 'til the neurotoxin makes you die!

[Black Turrets]

Maybe at the end I'll let you rest!

Portal here, portal there
Throw a turret in the air!
Watch for the bullets that'll graze your hair!

[White Turrets]
Everybody Run!
Everybody Run!
You're not safe in Aperture
I'm the bot with adorable face
Ready to shoot you in your place!

[Black Turrets]
I am the reject that gave you a scare!

[Recording]
I am the voice that you hear in there!

[Cave Johnson]
I am the head of this great place
And I just bought some rocks from space!
