Did You Know?


The PC version of Portal 2 has a classical secret. If you are playing fan made levels released to the Steam Workshop, most of the time, the background music that plays is an electric remix of Prelude in C Major No. 1 by Johann Sebastian Bach. See more »

Crazy Credits

The game menus change via a spinning tile effect, identical to the spinning tiles Wheatley and GLaDOS use in the game to create mosaic patterns and words on the walls of the test chambers. See more »

User Reviews

23 April 2011 | by (Nuremberg, Germany) – See all my reviews

Years ago, when Valve launched Portal as a fun Half-Life 2 mod, everybody was thrilled with the concept of the game. Portal 2 didn't just live up to the expectations I had, it slammed them harder into the ground, than I could have ever imagined. If this is no game of the year, I don't know what is... Portal 2's plot reaches much deeper into the history of Aperture Science, revealing new characters and shining a light on the events of Portal 1. Of course the humor most certainly made it to Portal 2 and I want to say, this game is even funnier than its predecessor. The new characters and the deeper plot make this game a must-buy, but that's not good enough for Aperture Science, I mean Valve: A co-op mode was the only thing missing from Portal 1, and they included it in this gem of video games. Challenging test chambers and hours of brain explosions await you and your partner in the Aperture Science Co-Operative Testing Initiative. If you liked Portal, you'll love Portal 2. And if you've never played Portal... do it now!
