Portal 2 Xbox 360 Microsoft Game Disc

Portal 2 takes place an indeterminate amount of time, somewhere between 50 and 50,000 years, after the events of Portal, which saw Chell destroying the sentient computer GLaDOS, and landing outside the facility, only to be dragged back inside of Aperture Science where she was ultimately placed in a Relaxation Chamber by Doug Rattmann for the indefinite future.

After considerable time has passed, Wheatley, a personality core, that has helped to maintain Aperture Science during the absence of GLaDOS arrives at the room of the awakening Chell. With a desire to flee the crumbling facility, Wheatley and Chell begin their quest to escape Aperture Science to return to the real world. After separating from Wheatley and completing a series of tests revisited from Portal, Chell reunites with Wheatley and head to what they believe will be escape. They must cross through the chamber of GLaDOS who lies broken and dismembered on the floor of her chamber, they enter the breaker room looking for a way out, and instead accidentally reactivate GLaDOS. They rise up through the floor just in time to witness GLaDOS pulling herself back together and taking over the facility again. Chell and GLaDOS quickly reunite, culminating with GLaDOS using a robotic arm to drop Chell into the incinerator, and guiding her back towards a new series of tests that GLaDOS intends to force Chell to run continuously until she dies.
