Sequel to the acclaimed Portal (2007), Portal 2 pits the protagonist of the original game, Chell, and her new robot friend, Wheatley, against more puzzles conceived by GLaDOS, an A.I. with the sole purpose of testing the Portal Gun's mechanics and taking revenge on Chell for the events of Portal. As a result of several interactions and revelations, Chell once again pushes to escape Aperture Science Labs.

Waking up in a seemingly empty laboratory, the player is made to complete various physics-based puzzle challenges through numerous test chambers in order to test out the new Aperture Science Handheld Portal Device, without an explanation as to how, why or by whom.

Portal: Still Alive is a retooled version of the original smash hit first-person puzzle game, with additional levels and challenges.

Featuring a darkly comic story that weaves adventure with brain-bending puzzles; 'Portal: Still Alive' also introduces 14 brand new bonus puzzles to challenge even the most skilled test subjects.
