Portal 2 draws from the award-winning formula of innovative gameplay, story, and music that earned the original Portal over 70 industry accolades and created a cult following.

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.

3 comments by laakkone on Feb 1st, 2015

After Chell finished her turn going through 19 challenging tests surrounded by lethal testing
elements and crackpot AI GLaDOS, it is time for that again. This time a "few" years later.

"The Enrichment Center reminds you that the
Weighted Companion Cube will never threaten to
stab you and, in fact, cannot speak.

Test chamber 17 is originally from Portal 1. I decided to remake it into Portal 2 using elements of overgrown theme.

"In the event that the weighted companion cube does speak, the Enrichment Center urges you to disregard its advice." -GLaDOS

So hurry up and find your way to the Steam Workshop page and hit Subscribe to order ticket back to Test Chamber 17 !

I wish valve would at least create a map loading shortcut in the game so you don't have to remember the exact name of every map you have.
