About This Game

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.

Product Features
  • Extensive single player: Featuring next generation gameplay and a wildly-engrossing story.
  • Complete two-person co-op: Multiplayer game featuring its own dedicated story, characters, and gameplay.
  • Advanced physics: Allows for the creation of a whole new range of interesting challenges, producing a much larger but not harder game.
  • Original music.
  • Massive sequel: The original Portal was named 2007's Game of the Year by over 30 publications worldwide.
  • Editing Tools: Portal 2 editing tools will be included.

Taking the beauty of Portal, with a much longer and diversified storyline, beautiful visuals, co-op, and steam workshop, there is no end to the world of Aperture Science.

Not on this Earth at least.

Great sequel to the inarguably best puzzle game ever. Portal 2 expands the story of its predecessor and gives a lot, new elements to add to the game challenge. It also has better graphics and longer gameplay.

One thing that I love in this game that didn't exist in Portal(1) is the Co-op mode. Nothing beats the fun of you and your friend strategizing their way through the chambers.

Summary, I think this game is a must have for almost everyone. If you have Portal(1), you must buy it. If you haven't both, I recommend you to buy the portal bundle. It is a pity living your life skipping this masterpiece.

First what i want to say is,if you havent played any of Portal game you should play Portal 1 before the sequel because you will lose the story and fun from Portal 1 even the prequel is from 2007.``SPOILERS``:I believe the game took me around 10 hours to beat it for first time but i was helped at harder chambers because i was a begginer still at that time.Now its 3 types of gels:BLUE gel that makes you jumping higher,ORANGE gel that makes you running fast and white gel that makes the unsurpotable parts for portals to be possibile to put them,new characters like Wheatley,also he is the antagonist of the game,also GLaDOs is now your friend almost at final of the game,also you will find more about the Aperture Science past.
Also is co-op mode that you with a friend,playing cooperative test chambers as robots,not humans,in beta Portal 2 Co-op,Chell and Mel (ununsed character) was the players,but in final co-op versions is 2 robots,one female other male,Atlas and P-Body,the person who host is Atlas (male) and the invited player is P-Body (female).Also the game have a lot more achievements than the prequel wich pretty much,mostly of them you will get passing the story of both moddes.Have fun with this game!

Amazing puzzle game with great mechanics !! Single player and great Coop mode to have fun.. For me the best the part though is the community levels !! 6 years since release and still the levels are enough to provide nice challenging puzzle experience.. this is a game that will stand the test of time.

Valve have never seemed to disapoint me when it comes to a campaign. Left 4 Dead, Half-Life, Portal, and now Portal 2. With Glados returning for revenge the story gets more and more intense. Running away from an vicious programme with menacing plans to crush you, Only being able to avoid her by supassing invigorating puzzles each getting harder than the next. To beat this game you need a quick brain and good at solving difficult tasks. Some tasks requiring smart movements, others precise timing and even a good accuarcy. If you've played other FPS games in the past you should be good. Even though it does'nt require inhuman ractions sometimes you can be on a tight time limit.

Portal 2 has changed since its first game, with Valve listening to community requests and even adding in small easter eggs and funny secrets to hopfully blow up the internet.

This game is for those who like using their brain and take time in puzzle solving.

Although i do wish the game was longer and even made a 3rd in the series. Please Valve, give us what we want!

It's portal, but better.

Not sure what you expect to read here,. it's portal, if you haven't heard of the game before, you should install it and play it. Yes it's that good. Is there any point in getting portal 1 if you have portal 2? Yes, because the puzzles are different, and the story follows up on the first one.

Also, the cake. Not spoilering.

It's a 3D puzzle game that requires you to think outside the box, and outside the box that the box might be in.
You might get frustrated so and then, but everything is perfectly doable.
