About Portal 2
Portal 2 is a puzzle game with a single-player campaign and a separate two-player co-op campaign. You explore Aperture Science Labs, solve test chambers using portals and encounter GLaDOS, the occasionally murderous computer companion from the original Portal.
Single-player campaign
The campaign introduces new characters, puzzle elements and a much larger set of test chambers. You explore areas of Aperture Science Labs that have not been seen before and reunite with GLaDOS.
Two-player co-op
Co-op has its own story, test chambers, gameplay and two player characters. To succeed, you must both act and think cooperatively, reconsidering what you know about portals.
Puzzles and tools
The game's physics allow for a wider range of challenges, making for a larger game without making it harder. Portal 2 also includes original music and editing tools.
