This is Aperture

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

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

[Turrets]
This is Aperture!
This is Aperture!
Test subjects die once they're in sight
This is Aperture!
Everybody hit the floor
Take a seat 'til the neurotoxin makes you die!

[Defective Turrets]
It's not safe! We are sure
You're not safe in Aperture

[Wheatley]
I am the one that's keeping you alive
Because, y'know, it's bloody hard to survive!

[GlaDOS]
I am the one that wants to test
Maybe at the end I'll let you rest!

[Turrets]
This is Aperture!
This is Aperture!

[Defective Turrets]
You're not safe, in this place
All of us warn you of the big white face!

[GlaDOS]
You are safe, don't you struggle now
Don't you want your nice big cake?

[Defective Turrets]
Down that corridor, running to the exit door
She is waiting there to grab and kill you!

[Turrets]
Run!

[Defective Turrets]
This is Aperture!

[Turrets]
White and grey...

[Wheatley]
...and slightly blue!

[GlaDOS]
Want some cake?

[Turrets]
Well, none for you!

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

[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!

[Defective 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!

[Turrets]
This is Aperture!
This is Aperture!

[Recording]
Testing subject usually die
Science isn't fun without cyanide

[Other Recording]
That's the drill and you may die
As you're not safe in Aperture!

[GlaDOS]
You are safe, don't you struggle now
Don't you want your nice big cake?

[Wheatley]
GlaDOS the giant may fill your room with neurotoxin!

[Turrets]
Shoot you with a rocket-turret - turn you into burning mush!
This is Aperture!
Everybody RUN!

[Defective Turrets]
You better escape to a much safer place!

[Turrets]
Our dear Chell is master of the portal-gun!
Everybody help her in her flight!

[Wheatley]
