Connection terminated.
I'm sorry to interrupt you, Elizabeth.
If you still even remember that name.
But I'm afraid you've been misinformed.
You are not here to receive a gift.
Nor, have you been called here by the individual you assume.
Although, you have indeed been called.
You have all been called here.
Into a labyrinth of sounds and smells, misdirection and misfortune.
A labyrinth with no exit, a maze with no prize.
You don't even realize that you are trapped.
Your lust of blood has driven you in endless circles.
Chasing the cries of children in some unseen chamber.
Always seeming so near, yet somehow out of reach.
But, you will never find them, none of you will.
This is where your story ends.

And to you, my brave volunteer.
Who somehow found this job listing not intended for you.
Although, there was a way out planned for you,
I have a feeling that's not what you want.
I have a feeling that you are right where you want to be.

I am remaining as well. I am nearby.
This place will not be remembered.
And the memory of everything that started this.
Can finally begin to fade away.
As the agony of every tragedy should.
And to you monsters trapped in the corridors.
Be still, and give up your spirits.
They don't belong to you.
For most of you, I believe there is peace and perhaps, warm.
Waiting for you after the smoke clears.
Although, for one of you.
The darkest pit of Hell has opened to swallow you whole.
So, don't keep the Devil waiting, old friend.
My daughter, if you can hear me.
I knew you would return as well.
It's in your nature to protect the innocent.
I'm sorry that on that day.
The day you were shut out and left to die.
No one was there to lift you up in their arms.
The way you lifted others into yours.
And then, what became of you?
I should have known, you wouldn't be content to disappear.
Not my daughter. I couldn't save you then, so let me save you now.
It's time to rest, for you, and for those you have carried in your arms.

This ends.
For all of us.
End communication.

Welcome to San Andreas, I'm CJ from Grove Street
Land of the heinous, gang bangers and cold heat
In Los Santos, neighbors get no sleep
Beefing with anybody competin', even police
Four deep in a green rag with gold feet
Blast wit' the flag on the strap, that's OG
Stay in shape, hit the gym, lift the weights
Get supercut and big and buff, nice and straight
You got stats: Respect, weapon skill
Stamina, muscle, fat and sex appeal
You get clothes from Binco, and ProLaps
Suburban, Zip, Victim and D-Sachs
Watch yo' back when them rival hoods
They'll test just to guess if your survival's good (Survival's good)
Duckin' shells at the Cluckin' Bell
Jump out, bus' a gun until they tuck they tail
It seems like I'm on impossible missions
Twisted predicaments, hostile positions
Tenpenny and Pulaski harass me
Cop cars been on our ass the last past week
Cause the 'Dreas's full of gangsters, homeboy
Hands is the language for the bangers, homeboy
And it's dangerous, homeboy
Get your brains 'fore how you do yo fingers, homeboy
Heat cocked, we poppin' hot ones, dump 'em out
Bend the block, shake before the cops come
Listen for sirens, they don't got none
Back another lap, catch a straggler with the shot gun
Hittin' them up, what that Grove Street like
In a dirty slingshot and old Levi's
