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.

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.

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!

The cake is a lie...

Wait, wrong game.

If you don't have this game, you won't understand my references if you are my friend, so therefore we cannot be friends.

10/10 would hang with GLaDos again.
Also would cuddle a turret.
And rock out in space with SPOILERS

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.

pros -
- really great soundtrack
- gameplay/puzzles/graphics have held up exceptionally well
- story and lore much more immersive than the previous portal
- funny without delving too deep into "xDDD this is a FUNNY GAME!!! do you get it?!?!" territory
- genuinely heartwarming conclusion
- a "must-have" for any pc gamer

cons -
- that one part (and you know exactly which one i'm talking about if you've ever played the game) gives me mad motion sickness every time
- there really are none

I've put over 110 hours into a game that has a 6 hour storyline. And that doesn't factor in the hours I put into it on my PS3. That should tell you something about how fun this game is. Between the writing of the characters, the level design, the voice work, and the concept of portals and addition of gels, this is the straight up funnest game I've ever played in my life. It's my go-to game for showing someone who "doesn't like video games" how much fun games can be. I can't imagine somebody playing this and not enjoying themselves.
