GLaDOS (Genetic Lifeform and Disk Operating System) is a fictional artificially intelligent computer system found in the Valve Software video game Portal, voiced by Ellen McLain. She initially appears as a voice to guide and aid Chell, the player's character, through the game's chambers, but over time, her words and actions become increasingly malicious, and she makes multiple attempts to kill Chell. After a face-to-face confrontation with GLaDOS, Chell destroys her and escapes. GLaDOS was universally praised for her contributions to the quality of Portal's writing, winning multiple awards for best new character from GameSpy, GamePro, and X-Play.
At the end of "Portal," Ellen McLain performs again as GLaDOS in a song called "Still Alive" by Jonathan Coulton, which has become an internet hit, receiving praise from multiple outlets for the quality of its writing. It has been featured in multiple installments of the Rock Band series as free downloadable content. It is also available for purchase as a part of the Orange Box original soundtrack on iTunes.
This was a triumph.
I'm making a note here: HUGE SUCCESS.
It's hard to overstate my satisfaction.
We do what we must
because we can.
For the good of all of us.
Except the ones who are dead.
But there's no sense crying over every mistake.
You just keep on trying till you run out of cake.
And the Science gets done.
And you make a neat gun.
For the people who are still alive.
I'm not even angry.
I'm being so sincere right now.
Even though you broke my heart.
And killed me.
And tore me to pieces.
And threw every piece into a fire.
As they burned it hurt because I was so happy for you!
Now these points of data make a beautiful line.
And we're out of beta.
We're releasing on time.
So I'm GLaD. I got burned.
Think of all the things we learned
for the people who are still alive.
Go ahead and leave me.
I think I prefer to stay inside.
Maybe you'll find someone else to help you.
Maybe Black Mesa
THAT WAS A JOKE.
HAHA. FAT CHANCE.
Anyway, this cake is great.
It's so delicious and moist.
Look at me still talking
when there's Science to do.
When I look out there, it makes me GLaD I'm not you.
I've experiments to run.
There is research to be done.
On the people who are still alive.
And believe me I am still alive.
I'm doing Science and I'm still alive.
I feel FANTASTIC and I'm still alive.
While you're dying I'll be still alive.
And when you're dead I will be still alive.
