Publisher Valve's sleeper hit of 2007 returns with a new single-player story mode, two-player cooperative action, and new physics-based challenges to overcome. As in the original game, Portal 2 involves figuring out a way through a series of rooms within Aperture Science Labs, a futuristic facility that exists within the Half-Life universe. You'll fire a portal gun to create openings and exits within each area, allowing you to traverse the environment and manipulate objects in unusual ways.
