The wait for Portal 2 was worth every second. I finished the game in a satisfying 8 hours with some very challenging puzzles, and with Valve's usual sense of humour in the Portal series, this game had me grinning at every small events in the game. Voice acting in this game was spot on, Stephan Merchant and Cave Johnson did a bloody good job with capturing the character's personality. All in all, this game is fantastic. I would definitely re-play it in the not too distant future.

This game is the greatest fun. I enjoyed plaing the first Portal very much, but Portal 2 has reached a higher standard. The Co-op mode is particularly nice. I spent quite some time plaing it with a friend and the comments in the game are just too good to be true. I´d recommend this game to just about anyone, because everyone would love it.

Great game, the sense of humor is just amazing, the guys at valve just have made the best puzzle game since ages. And while doing that, making a graphically great game as well. The only little remark is that the puzzles could have been a little harder, but other then that, great value for money, awesome game:D!!!

While Portal was a great game, Portal 2 is still up to challenge the first title by adding different tools to play with such as paint, jumpers, light footpath, and so on. Humour is there all along the well paced solo game. You'll get some nice coop to play which bring the ability to open 4 portals at the same time making puzzle room quite challenging. Voice acting is great. Great game !

Portal 2 is an excellent sequel. It's twice as long and twice as good with new interesting gameplay mechanics that will have your head in a puzzle. Portal 2 is one of the most intelligent and the most hilarious game of the year and In my mind game of the year. A must buy!

Portal 2 is an immense game! Portal game, you will absolutely love this one! I would strongly suggest to everyone that they buy this for their collection.

A great step up from the original game. Enhanced graphics and a great story line to follow it, A great step up from the original Portal game. I found it a bit harder than the original as well as being more intense and graphically better. I had high expectations which were met from Valve as I thoroughly enjoyed Portal 2. It is very funny, and at times scary, but this is due to the sheer scale of the game. Highly recommended!

I played Portal 1 already a while ago, and loved the concept. Therefore I couldn't wait for the release of Portal 2. Once it was available, I directly bought it, and had my share of playtime in the first few days. The singleplayer story is great, and the multiplayer puzzles are excellent. Even though you can finish the story line in just a few hours, it's worth playing over and over again. You really need to buy this!

This is definately the most hilarious game I have ever played, where every line of dialogue is either a witty response to another character or just an insult thrown in your direction. Stephen Merchant surpassed my expectations in the game with his comedic effort to make his character 'Wheatley' as lively and as interesting as possible which, for me succeeded. I thoroughly enjoyed the 6 -7 hours of gameplay in Portal 2 which brings back and adapts on what Portal bought to the gaming industry. Without spoiling too much, this game brings a lot more to the table as different gels are now getting involved along with various other materials requiring the player to think outside the box in order to complete every upcoming level. The story is as great as you'd expect any Valve creation to be as Portal 2 refers a lot to the original Portal story, though doesn't directly continue from it. Though I undoubtedly enjoyed this game I feel as though there will be next to no replay value in it, which is the reason for my regretful 4 Star Rating. I have not referred to the online / co-op content as I feel Single Player is the controlling and most important aspect of any game as where Multiplayer is more of an... addon than anything else. People should make their judgement to buy a game solely based on the Single Player! Overall I found Portal 2 an excellent game, constantly making me think of new ways to complete every puzzle it presented me. It was certainly a challenge and that's what's made Portal 2 one of my highest rated games of all time!

If you liked the first game this really needs no introduction. Portal 2 enhances the portal puzzing experience with an engrossing story that unfolds during the game and all new puzzle elements that will wrack the brains of even the most experienced player of the first game. An incredible experience and a must buy you will want to play over and over again.
