Title from disc surface

Set far in the future from the original Portal game, awake in the Aperture Science Labs as Chell, a former test subject trying to gain her freedom from the facility and GLaDOS, the AI controller of the facility. In escaping your initial confinement, GLaDOS is also reawakened. Set in the test chambers of the facility, your goal is to make your way through the game levels using your portal gun to create temporary passages through solid surfaces, allowing for creative platforming and multiple possible means of clearing a level. Puzzle solving at times is needed to clear sections of levels
