Core Hub era GLaDOS

You were suddenly awakened from stasis as a test subject to pass the puzzle test chambers with buttons, cubes, lasers, energy balls, turrets, jump pads, light bridges and portals while listening to prerecorded messages, having a robotic feminine voice.

But the Aperture Science underground complex is completely uninhabited, with a decaying, industrial appearance devoid of heavy overgrowth. Now it is completely abandoned, the facility is in ruins and barely holding together, almost like its caretaker is missing.

Along the way, while following red wall marks, you find the Handheld Portal Device in ruins, which helps you navigate past obstacles to reach the central chamber belonging to GLaDOS, who hangs lifelessly as a carcass from the highest ceiling in a room that seems to float in a dark void with destroyed walls and equipment. Your attention is drawn to one of the surviving big screens at the top of her construction. It is playing unrelated, chaotic video fragments.

The only thing preventing her from turning on is a fuse missing a component, which conveniently lies right next to you. Will it be plugged back in?
