They trapped me inside of Aperture Science  
Where chatty AI’s are lacking compliance  
Been napping a while, the lab is so quiet  
GLaDOS is yapping but I am happily silent  
I question if I should ask her for guidance  
As I grab a device, a crafty appliance  
I’ll get through hazardous trials, deadly assignments  
I’ve been traveling like a dimensional pilot  
Bye gravity, I would rather defy it  
Why think inside of the box? I’m stepping outside it  
I was promised cake, but I’m back on a diet  
And I’ve yet to decide if GLaDOS is lyin’  
She’s acting all nice, she’s actually violent  
Her cameras are live, she’ll laugh as you’re dying  
Like the mass homicide of Aperture Science  
“What happened to my morality? Fried it”  
That’s it, GLaDOS, I quit
 
As one door closes  
Another opens  
But there are no keys  
See, I control them  
My test has begun  
Now that you’ve woken  
Your dreams of freedom  
Keep you in motion
 
If I can’t find a door to get through  
A portal will do, just connect orange and blue  
Ignore personality cores who try to be cordial  
A moral code ain’t what that normally use  
I might have side effects of isolation  
I spied somebody and then I tried to chase em  
But all I’m finding is myself, I’m kinda shaken  
Feels like a paradox that I might be makin’  
Am I flying down or falling up  
Cuz the guide I had has gone corrupt, yup  
The writing on the wall’s enough  
To find all her lies, and call her bluff  
My companion cube - I’m not forgetting you  
Remember all the times that you helped get me through  
Rest In Peace my friend, but your death’s avengable  
When I make GLaDOS a sentient vegetable  
Forget the cake - now that she’s edible
 
As one door closes  
Another opens  
Live hands me lemons  
But I don’t hold them  
I’m keeping secrets  
Can you decode them?  
I had a conscience  
But it was broken
 
Another test, I can pass that  
Impossible? I think I’ll have a crack at  
Too bad that it took me this long to see  
GLaDOS snapped, and I’m nothing but her lab rat  
Fact - never mess with Aperture Science  
Accept death, cuz they’ll never ask for your silence  
“We do what we must because we can”  
So just lock ‘em up, and run tests on them  
Black Mesa - no competition  
It’s in the name - Aperture got the vision  
Bring your daughter to work if you want her missin’  
It’ll become her grave, if it’s not her prison  
This is a half-life that I can’t live anymore in  
Just forming portals - wormholes I’m borin’  
But let me test out your turret performance  
As you send me off with an uplifting chorus
 
As one door closes  
Another opens  
You will have no friends  
Because you smoked them  
We all have secrets  
Now we can show them  
I know you well chell  
I’ll let you go then  
I’ll stay behind I like it inside  
More tests to run down here, and besides  
You’ve overcome all odds to survive  
We’ll see how long you make it outside
 
Surprised you’re still alive  
It’s time for you to die  
And I’ll still be alive  
And I’ll still be alive  
And I’ll still be alive  
And I’ll still be alive  
And I’ll still be alive

That’s my cube
