In the Aperture Science facility, player-character Chell wakes in a stasis chamber resembling a motel room. The complex has become dilapidated after what appears to be millennia of decay. Wheatley, a personality core, guides her through old test chambers from the first game in an attempt to escape the facility after its reserve power is depleted. They accidentally reactivate the dormant GLaDOS while attempting to restore power to the escape pods; she separates Chell from Wheatley and begins rebuilding the laboratory. GLaDOS subjects Chell to new tests until Wheatley helps her escape again.
Portal 2 is a first-person perspective puzzle game. The player takes the role of Chell in the single-player campaign, as one of two robots—Atlas and P-Body—in the cooperative campaign, or as a simplistic humanoid icon in community-developed puzzles. Characters can withstand limited damage but will die after sustained injury. The goal of both campaigns is to explore the Aperture Science Laboratory—a complicated, malleable mechanized maze. While some parts of the game takes place in modular test chambers with clearly defined entrances and exits, other parts occur in behind-the-scenes areas where the objective is less clear.
