Portal 2 expanded upon that perfect formula of portal 1 into something even greater. The gameplay is silky-smooth and intuitive, and the feeling of freedom in solving problems is both satisfying and very rewarding.

The way the game introduces and teaches you to master the new mechanics, like the propulsion and repulsion gels, is brilliant, layering each concept naturally into the puzzles without ever feeling overwhelming.

In this game especially, the story, voice acting, and atmosphere take center stage, masterfully binding it all into a perfect experience of humor, wit, and innovation.

and it has alot of content both a great single player mode and the co-op mode i have yet to experience it again as i've played the co-op mode before on console. and how can we forget about the great community of portal 2 workshop.

Portal 2 is not just a game; this is a timeless work of art. i 100% recommend this game also worth the price.

please make more single player games valve

Definition of a perfect game. Beaten it twice now and it makes me emotional every time
