Worthplaying has posted a collection of new screenshots from Valve Software's upcoming first person action puzzler, Portal 2. The sequel is due to launch on Mac, Playstation 3, Xbox 360, and Windows later this year.

Portal 2 will see players introduced to a host of fresh puzzles, devious new test chambers in never-before-seen areas of Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion from the original Portal.

Features single and multiplayer co-op modes. The single-player portion 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 never-before-seen areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion who guided them through the original game. The game's 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 to not just act cooperatively, but to think cooperatively.
