Awesome game, awesome voice acting, awesome storyline.
11/10

I've bought this game a month ago and I started playing it last week and I'm SAD...

...sad that I didn't start to play it immediately when I bought it
...sad that I didn't buy it earlier - A LOT EARLIER

Portal is one of the best physics based puzzler games I've played. Not only are the puzzles challenging, but the game itself has been made a lot of fun as well with those 2 robotic personalities.

If this game was a potato, It would be a very good potato.

Portal was sort of a little experiment of a huge company. That’s why success of the first part of the Portal was a surprise even for the VALVE. Therefore seriously question arose about the Portal 2. And what we got? Let's see.

　STILL ALIVE?

　　The game begins with the fact that Chell along with her new partner, personality module Wheatley, is trying to escape from an abandoned Aperture Science laboratory. Throughout the game, the plot makes a interesting twists. Individual deserves compliments perfect finale, after which there remain only a warm feeling. In Portal 2 no epic stories, huge explosions, incredible action, or the salvation of humanity. Instead, there is a charismatic characters, intelligent humor and interesting puzzles.

　ONE IS GOOD, BUT TWO IS BETTER

　　One of the achievements of the new Portal has been the emergence of the cooperative. Co-op story is a continuation of the plot of the single player. At first I thought that the only difference of the cooperative is the presence of two players with portal-guns, instead of one. In fact, the cooperative has unique ideas. Many puzzles solving quite differently. I advise you not to play cooperative with a random person (there is that possibility), and play it with a good friend.

　ENDLESS TESTS

　　In game was added a level editor, so anyone can create their own test chambers or try to play the levels of other players. To be honest, most of the player-created levels are too simple or ridiculous. But there is sufficient interesting maps (and some of them really hard). In no case do not miss the community maps.

　Multiplayer:
　　Online: Θ Θ Θ Θ Θ Θ Θ Θ Θ Θ
　　Co-op: ☺☺☺☺☺☺☺☺☺O
　Storyline: ☺☺☺☺☺☺☺☺☺O
　Graphics: ☺☺☺☺☺☺☺☺☺O
　Gameplay: ☺☺☺☺☺☺☺☺☺☺

　

　Complexity of the achievements: All achievements can be easily earned (if you have good friend for the co-op) in the one-two walkthrough.

　　　　VALVE made another good
　　game. With good intelligent humor,
　　charismatic characters and unusual
　　interesting gameplay.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　As expected, nine out of ten [9/10].

Game very much was pleasant to me as well as single game, and a multiplayer. I advise all to fans to think over. All game on logic and mind. In single game I liked a plot, it well continues a plot of the first part. And in a multiplayer well develops in itself a team game, and it is so possible to have fun simply with the friend (Bubble_Gum [RUSская]) approves)))). I recommend to all, won't regret! ! ! (This my opinion and it can not coincide with yours).

The best game ever made by Valve. Great story, beautiful dialogues with funny jokes, interesting puzzles, perfect atmosphere and a lot of fun in co-op with friends. You made a great work, Valve, and thank You for this absolute masterpiece.
10/10.
