You woke up in the Aperture facility, you expected to hear GLaDOS but everything was oddly silent, you moved to the first test chamber and grabbed the cube to place on the button but then when you turned around a cube had already been placed on the button, you move on and after a few chambers you see a dead body laying in the chamber, you were a bit scared but moved on, but then you saw “I will stop the elevator” written on the wall in red, as the writing says the elevator stopped, you can jump down the elevator shaft and escape the facility, when you do a loud static is made and you’re teleported back, the elevator goes fully down
