Portal 2 is an acclaimed puzzle video game that expands upon the innovative gameplay and story of its predecessor. Players return to Aperture Science Labs, encountering familiar faces like GLaDOS and navigating a vast array of challenging test chambers filled with new puzzles and mechanics. A unique cooperative mode introduces two new characters and a separate campaign requiring players to work together strategically to solve puzzles. Portal 2 features cutting-edge physics, an original soundtrack, and advanced editing tools for creating custom content.
