Portal 2

"Aha!" that is the word you will be saying most to yourself as you progress through Portal 2's nine chapters in the single player campaign. These test chambers or individual puzzles you progress through are so cleverly designed, that once your about to give up you find the perfect piece of information you were missing in order to solve the puzzle.

The game starts off as you awake from suspended animation, several hundred years after the events of the first game. You play as the same silent protagonist "Chell", and are broken out of containment from an artificial personality core named "Wheatley" in an attempt to escape the Aperture Science facility while accidentally awaking GLaDOS (Genetic Lifeform and Disk Operating System), the chief antagonist of the franchise in the process. Eventually your put through another series of test chambers but things take an interesting turn in the second act which I won't spoil.

The gameplay from the first installment remains mostly the same with developer Valve adding several new elements to freshen things up. First off, the art style has changed with the setting of the Aperture Science Facility having been dilapidated for so many years. Overgrown vegetation and ruined architecture freshen up the scene as well. Tools such as Repulsion and Propulsion gels, Excursion funnels, Aerial Faith Plates, Thermal Discouragement Beams add a new level of complexity to the puzzles, but the development team does a really great job of introducing you to these new elements, allowing you to master them before they hand you a new thing to play with. It's all great fun!

Graphics wise, the eleven year old source engine that the game is powered on continues to be updated with some great lighting effects and animations with a mostly steady frame rate, but the loading zones should definitely be trimmed, especially for a game this late into the console life cycle. The audio work is fantastic helped by the hilarious dialogue voiced by Stephen Merchant, Ellen McLain and J.K. Simmons. This is truly the funniest game I've ever played!

The game is well worth its sixty dollar retail price with an equally long two player Co-operative mode (which wasn't available at the time of this review due to PlayStation Network being down) and developer commentary throughout the single player story mode. The PlayStation 3 version (which I recommend over the Xbox 360 version) comes with Valve's SteamWorks support, a popular service on computers which allows for cloud saving and automatic updates not previously available on consoles. Two people are able to play with each other cross-platform from the PS3 over to PC or Mac, which is a fun bonus.

The take away from this experience is the atmosphere of the world you are re-introduced to. The game trains you in solving puzzles based on the physics of forward momentum allowing you to walk away from this game feeling smarter than before. The themes of isolation and science as a main priority above all else, are minor messages scrolled into the background, similar to the environmental storytelling you will find written on the wall of the game world, in one of the best games of this year.

Rating: A

Portal was an already excellent puzzle game. Portal 2 however expands everything from the first game and makes it eleven times better. The puzzles are bigger, the stakes are bigger, the Enrichment Center is bigger. But let's not get ahead of ourselves.

Chell has been kept in stasis for a long time since the first game ended and is awoken when a tiny personality core named Wheatley tries to break them out of the facility. Chell and Wheatley pass through a few test chambers before accidentally reawakening GLaDOS, who has many more tests for you. You have to get out of the facility and finally escape GLaDOS and Aperture Laboratories... at least at first.

Portal 2 is one of the most fun games I've played all year. The puzzles have the same basic formula of portal shooting as the last game but there's a lot other stuff thrown in as well. New gels that propel you and increase your speed and a lot harder puzzles that will keep you guessing.

Not only does Portal 2 increase the puzzles, it also goes deep into character development. When you go deeper into the facility you find out the truth about Aperture's origins and also the origins of GLaDOS.

Portal 2 is one of the best games of the year. If you haven't played it, I strongly suggest it. You'll laugh, you'll get frustrated, and you will be heavily engrossed in this amazing game.

This game is truly magnificent. The game's atmosphere is amazing. Valve really nailed the mysterious abandoned laboratory feel this time around. They knew they couldn't just rehash Portal, so they tried something new and it really paid off. The puzzles are fun and challenging, but not infuriating, and the way that the game chooses not to have any cut scenes breaking up the game play makes the game much more immersive. It's easy to get lost in this game for hours. The story is wonderful, and the ending is powerful. I would highly recommend this game to anybody who likes puzzle games, story telling in games, or games in general.

It was only recently that I discovered what has been public knowledge for a long time – that Portal is a great game. I decided to jump into Portal 2 recently on the basis of enjoying the first game so much. True to form, Portal 2 does not disappoint and everything good about the first game is present, polished and improved here – well, pretty much everything.

The game begins the same as the first one did, with levels that introduce you to the world of portals gradually so that you get the basics before the puzzles start getting a bit harder. This is normal with sequels because the makers cannot assume players are familiar already but at the same time have to try not to bore old hands who have seen this all before. Here there is no such problem because while I was already familiar with the ideas I was being introduced to, I was not familiar with Wheatley. At first Wheatley (voiced by Stephen Merchant) is your guide and he is hilarious and he makes the introductory levels a lot of fun to play with his comments and advice: this is a game that tells you which button is "jump" by getting you to push in to "speak" and then judging your character for jumping. It is hard to describe but fans of the first game will know the style of humour at play here and indeed fans of Stephen Merchant should also know, since he is doing his usual stuff here (most notably like he did in Extras – the cheerful numpty).

The single player game takes you through the same sort of test rooms as before but plot developments see you exploring different areas in the facility as well. These areas tend to be more broken down and the differences in them does serve to rather break you out of autopilot to a point. At times it is too easy to solve puzzles by simply observing the room and recognising the process rather than solving the puzzle, the change in location made me have to pay attention more. Also in addition to the varied locations we also have substances added which have particular properties and play a role in solving puzzles – these also serve to break up the "routine" of knowing where to put the portals and makes for some nice puzzles. There are also laser and other new things but rest assured that the trusty companion cubes remain. I still didn't find it particularly hard but I do think it was a little tougher at times than the first game – the makers said the focus was to make the game bigger but not necessarily harder and they did do that.

Of course bigger does make it better and I think the single player game was about 10 hours which, considering it is very similar throughout, it is testament to how engaging it is that it never gets boring. The story helps as we have great characters in GlaDOS, Wheatley and Cave Johnson, all of whom are really well written and hilarious but yet also charm and engage – they can be tragic, threatening, cruel or insane but the player always likes them and is entertained by them – like the turrets, even when they are trying to kill you, you always feel bad about knocking them over! The dialogue is key in making this work and it is really well written. Johnson's dialogue is funny and also informative in terms of back-story, while GlaDOS is as evil as ever harbouring a massive grudge from the last game and constantly making lots of little digs at the player about their weight or about their parents not loving them. Again, it is hard to explain how funny it is but my girlfriend (a hater of video games) loved watching me play – although was always impatient for me to solve the puzzle so she could get the next piece of dialogue from GlaDOS etc. It is hilarious and it is this way throughout – the final song is not quite up to the standards of "Still Alive" but to be fair – what is? The delivery of the lines is near-perfect. McLain returns as GlaDOS and various other voices, while JK Simmons (yes, Schillinger from Oz etc) is really great as Cave Johnson. Standout though is the cheerful little bumbler Wheatley as played by Merchant. A great character and Merchant totally fits, delivering by far the funniest performance I have seen him give.

The graphics are not amazingly stepped up from the original game but some of the areas outside of the testing rooms are impressive in their complexity and detail. However those looking to be wowed by technology will not be here but in fairness it isn't what I came for and it did still look good. The addition of the co-op may only add another 4 or 5 hours to the game but they are great addition. The use of four portals and two players means that the dynamics are really well changed and they worked my brain a little harder because I had settled into a rhythm with the main game. It also features a nice little plot and loads of the usual humour.

Overall Portal 2 is a brilliant game. The puzzles are good without being really difficult – I still found it a bit too easy to solve but many did give me pause and made me think for a minute before sorting it out. The humour is key though and this game is hilarious and engaging at the same time. The characters are brilliant in the writing, the dialogue and the delivery and I have (and will) replay parts just to hear the lines again. A great game – clever, engaging, funny, exciting and with twists and turns in the plot. Buy it now.

I never expected a sequel to the first-person puzzle-game Portal to be any good, but they actually managed to create a very well-produced game that relies on great voice-acting and creative level-design. Its clear that Valve is pushing their aging Source-engine to the limits with Portal 2, but they still manage to create some of the best looking levels I've seen in a good while. The game involves a more active story-line then in the first game, but it never distracts too much from the brain-twisting puzzles. And yes, the puzzles are harder then in the first game in my opinion, although they are never near impossible if you know where to look and pay attention to the level. It also features more levels then the original I think. The first Portal took me only a few hours to beat, while Portal 2 took me two days.

A couple of new elements are introduced this time around, to keep the game refreshing and preventing the levels of getting too predictable. This is done in the form of different gels (liquid substances that either make you jump high, or run fast on contact). There's also a white gel that allows you to shoot portals on whatever surface it is spilled on. Regular water allows you to wash either one of the gels off. Besides that, there are also light-bridges that allows you to portal a walkable bridge to otherwise unreachable places, and some kind of anti-gravity beam that propels either you or objects like turrets and boxes into the direction it faces (which can sometimes be altered by pressing a button in the room).

Last thing I have to mention is the music. The music ingame, as well as the ending-music (which was particularly popular in the first game) called 'Want You Gone' by Jonathan Coulton are great. It all fits the game's robotic atmosphere perfectly as well as the ingame glitch-beats that you can hear mostly when the action intensifies.

As you can already make out, Portal 2 allows for some very diverse puzzle-elements, and this together with the already established portal-gun makes it a lot of fun and challenge to play. The story isn't too exciting, but the witty humour and overall superb voice-acting makes it worth while (kudos to Stephen Merchant for providing his voice-talent for such a funny villain). Its a bit early to say with such a long time ahead of us, but I wouldn't be surprised if Portal 2 would end up on many people's lists of best games of 2011. Go play it, you won't be disappointed!

Now, if Valve Software would only get some information out the door regarding Half-Life 3, I would be their number one fan!
