At the last half of the game... (SPOILERS)

[poop100]

GLaDOS went and killed almost everyone in the facility, Then why are there no corpses in the halls and rooms? Did GLaDOS clean them up somehow? And also you never meet anyone else. I guess you're the last human in the AS.

 

[Acepilotf14]

There are other people still in Stasis, as you were.
GLaDOS has been testing them.

 

[Yorick]

Yeah there could be other people in stasis too.

About the bodies, the facility might have some kind of cleaning robot that goes through the place or something.

 

[Hellrider]

How\why were you in stasis in the first place anyway ?

 

[poop100]

A theory sugests that you were a daughter in take your daughter to work day and glados got you.

You were'nt an employee because glados says that at one point.

 

[tetsuo2040]

She refers to you as a Test Subject all the time.

Never an employee.
