It won countless awards for its accomplishments in gameplay innovation and narrative. It resonated with gamers from all across the spectrum of Hardcore and Casual.

When Valve announced a Portal sequel, they set down a gauntlet of expectation with one simple phrase, “Portal 1 was a test bed, and Portal 2 is the game.” With the bar set higher than ever, does Portal 2 exceed the standard that its predecessor redefined?"
