Portal 2 has won over 70 industry awards and garnered a loyal fan base.

The single-player mode of Portal 2 introduces a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers.

Players will explore new areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion who guided them through the original game.

The two-player cooperative mode features its own entirely separate campaign with a unique story, test chambers, and two new player characters.

This new mode forces players to reconsider everything they thought they knew about portals.

Success will require them not only to act cooperatively but to think cooperatively.
