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.

  • Complete two-person co-op: Multiplayer game featuring its own dedicated story, characters, and gameplay.

Do you like spending time with family and friends?

Not for the first 20 hours of this game you don't.

An extremely good story, both in singleplayer and multiplayer mode. Don't expect to get hundreds of hours on this game though. Both the singleplayer and multiplayer servers are about 10 hours of story, combining to a solid 20-30 hours of good gameplay, but after that, there isn't anything else you can do with the game, apart from a level designer. However, the game has great graphics, a great story, great puzzles, and great characters. Would absolutely recommend.

Nice piece of art that follow the story of Portal. I really enjoyed this one and the coop mode is one of the best i've ever seen.
But I still don't get why people want a Portal 3. The story of the Portal serie is achieved and there is nothing more to tell. All the remaining questions are from the half life serie. Furthermore there is a bunch of tools to create your own puzzle map and upload them to the workshop. By the way you should absolutely try the famous one and some mods made by the community.

You can make an infinite loop with the portals and fall forever, 10/10. But seriously, this game is great, i cant tell you how many times I've replayed it, and every time I enjoy it. It never gets old, and being able to play comunity chambers makes it last even longer. It's hard enough that you dont breeze through it, but easy enough that it isnt too frustrating. Very Very Good Game.

In Short -

Portal 2 is one of Valve's most recent titles, and is very well made, I think we can all agree. It is the sequel to the critically aclaimed game 'Portal'. Now, Portal has become so popular that I don't believe I need to explain the game's mechanics; it is such a simple concept and yet has been parodied and explained 100s of times across the Internet. Portal 2 expands on why we all loved Portal, with new mechanics, new story, new characters and new settings. The game keeps it's original mix of difficulty and ease to make a title that you can play in almost every mood. Portal 2 has so much replay-ability, that I've played the game 77 hours; beating the single player campaign three times and the Co-Op campaign twice, gaining every achievement. And not once did I get bored of playing, not once did I think 'this is getting boring', as quite a few games would make you feel after 77 hours.

More In Depth -

Portal 2 starts out waking the player up an unknown amount of time since the last game. The announcer even breaks, from saying so many '9's, of time that you've been there. After a fairly slow start, you get thrown into testing almost immedietly. Although I'd like to ignore the story for the sake of the review, it helps keep the flow of the game. The story puts together reasons to add new mechanics, instead of just slapping them in and hoping fans overlook it. The game makes sure to keep it's ties to Half-Life in secrets hidden around too, which I find really interesting.

Portal 2 does even better than the original game at keeping it puzzle centered. It keeps itself faithful to what Portal built, and made tests that require quick thinking like an action game, as well as thought out and intricate thinking like a puzzle game. Not once does the game hand the player a weapon, which I feel is a good thing. Portal is like Half-Life's puzzle counterpart. You go to HL for action, and Portal for puzzles, which I really like.


Portal 2's Singleplayer mode carries on the story from Portal, as I said. We are given a ton of new tests, with new mechanics such as mobility gels, light surfaces, excursion funnels, but keeping Portal's mechanics such as flinging, momentum and turrets, occasionally mixing them together to make a game worth the label 'created by Valve'. Our original only characters, Chell, GLaDOS and the Companion Cube are brought back in Portal 2, each as main characters, still, while bringing on a new main character, Wheatly. His character was made very well, with the perfect voice actor for his lines, the perfect lines for his voice actor, a hilarious personality and more. He was even added into Team Fortress 2 as the Ap-Sap (my favourite sapper). All in all, Portal 2's singleplayer is definitely fun to experience. It's something you can sit down and play in the evening and feel relaxed. A mug of tea, a warm blanket, and some puzzles.


Now, I think I should probably preface this with a disclaimer; I don't dislike Portal 2's Co-Op. I've played it with three friends, and gotten every achievement for it (thank you Ambiticus, Roger and Sammy for helping me with all the achievements :3)

I felt, personally, that Co-Op was very shoved in your face and rushed, unfortunately. After how much I enjoyed Portal, when I bought Portal 2 I was hoping for something very similar; more story, more challenges and more of my favourite characters. And, although there are those things, there could be more if it wasn't for Co-Op. We are given two, barely distinguishable robots with 'personalities' that are really just a couple forced quirks given to them. The puzzle aspect is good, they use the two players to make puzzles impossible without teamwork, and, obviously, four portals, getting you across new distances otherwise impossible with one portal gun. However, this is just brought down by the rest of it. GLaDOS is written completely different to how she usually is. Instead of a passive-agressive AI, she is clearly just agressive, which really makes no sense. One of the best things about GLaDOS is that she is terribly passive-agressive, and for whatever reason, in Co-Op that is all just flung off the table, and instead we have a new GLaDOS; one that is just plain agressive, messing with the robots' friendship by saying different things to eachother, exploding them at the end of each course, and generally just being mean. This doesn't fit her at all, and it makes me almost sad to see how they did this.

PROs 'n' CONs

PROs -
  • Both single player and two player gameplay.
  • A level creator, connected to the Steam Workshop, so you can make your own puzzles.
  • Many achievements, to leave an achievement hunter with a lot of work to do. These achievements span across single and multiplayer.
  • Gameplay faithful to the original Portal.
  • Although the above statement is true, they still seamlessly add in new mechanics to enhance the gameplay.
  • A fairly big game. Playing through singleplayer and multiplayer without achievement hunting was probably almost half of my time in this game.
  • Fun, lovable characters, that are easy to get used to.

CONs -
  • Co-Op, although the gameplay is fine, is very rushed in nearly every other aspect. The characters don't have personalities, although Valve obviously meant for them to, GLaDOS isn't normal, there is very little continuity, and- Honestly, I could go on, but a rant isn't what I'm here for.
  • I have to say, honestly, that Portal 2's ending song, Want you Gone, will NEVER be as good as Portal's, Still Alive.
  • I like to have subtitles on, in case I miss a line of dialog, and there were multiple times in which the words and subtitles did not match at all. Words, even sentences would be off.
  • The developer commentary just wasn't that great, compared to Half-Life 2 or Portal.

    Final words

    Portal 2 definitely has good and bad aspects. It is a fun game in many ways, yet I believe it just wasn't finished. It had potential, and while most of it was met, it just isn't all there. I'd recommend the game, but I hope that Portal 3, whatever form it takes, will be better.

Awesome game, even better than the first which is quite an accomplishment. It's still Portal but better with more story and more puzzles. Really wish we will see a 3rd title in the series because there are still a lot to explore!

Portal 2, the sequel to the original masterpiece that the whole Valve community loved. This one is better.

I am going to give it some Pros and Cons:

-Longer story than the original Portal
-Jump height increased a little
-Better graphics
-The Cooperative Testing Initiative
-Replaying the tests from the original Portal
-New designs for the Cores, GLaDOS, The Turrets and more
-Fun stuff in the game (Serious injuries may occur -GLaDOS)
-Great Easter Eggs

-Defective Turrets
-A line for Caroline being unused
-"Don't Say Goodbye" being unused

I really really really REALLY love this game and I highly recommend playing it! :)

Thank you for reading,

Portal 2 is a truely unique puzzle action game which makes great use of a portal gun that can form two seperate portals which would allow the player to traverse the levels.

A great sequel to the original Portal game, Portal 2 is a much longer game which features much more complex puzzles and introduces lovable new characters. The voice acting and dialogue in this game is amazingly entertaining and funny, I found myself chuckling multiple time during the game due to the character dialogues! The level design in this game is also great as there were some levels which left me stumped for quite awhile and it took me quite alot of brain power to solve them and that gave me a great feeling after doing so!

This game features a co-operative mode which allows players to play with people in your friend list or complete strangers through match-making. There are some form of customization options such as hats in the co-operative mode that can be unlocked through completing the game. There was supposed to be more customization options available in a shop but it has since been discontinued. Trading is also unavailable which is pretty unfortunate as it would be great for players to exchange or sell cosmetics.

There is also a level creation tool in this game which allow players to create their own Portal 2 levels and share it online with others by uploading it to the workshop! Several interesting extra content includes a portal 2 comic which serves as a prequel to the game and a super 8 (a pretty old movie by now) interactive game demo.

Overall, Portal 2 is a very entertaining game with great puzzles, characters and voice acting. I would give it a 9/10! A must buy if you enjoy action puzzle games!

Challenging puzzles, top notch characters and story, INSANE soundtrack and on top of that you have one of the best co-op you will ever experience. Not playing this game is a sacrilege against videogames gods.

Portal 2 is probably the only one of very few story-driven puzzle games, that are actually good and not being pretentious.
