    It is an excellent and addictive game. Must play.

    A very fun (and very short) little game, a FPS puzzle game, which is a genre I didn't enough know existed until now. This portal concept is something I would love to see in a straight puzzle game: no villains just tons and tons of puzzle maps to play would be amazing. However, I thought GLaDOS was a wonderful character (which is important, being the only one besides the player) who worked well as an insane killer robot. I barely fnished her off in the end, because I was having so much fun listening to her mocking dialog ("your file says you were adopted and you have no friends, ha ha!"). Highly recommend to anyone that likes puzzles or games that play with physics. Expand

    Excellent, addictive game.
    It has an inventive concept, a funny, well-observed (well, as much as it can be) script, and some lyrical dissonance at the end that'd make Todd Edward Smith flinch.
    Yes, it IS short, but I forgave this once I heard there's a sequel coming out.

    When I bought the Orange Box, right after it was released, I really don't expected too much about portal, I bought that because of HL2 and TF2, but portal seemed to be a great game, it could be compared to HL2 when it was released. Something innovator, but it does not deserves 10 just because it's different, it deserves 10 because it is unique, adictive and captivating. There's no one who can fake someone (or something) like GLaDOS. Portal is unique. Expand

    The best game I'v played, ever. The Antagonist (enemy, bad guys, ext.) is GLaDOS, the AI who runs Aperture Science, is the best enemy in any game, unlike in Halo 1 were the Covenant are basically the 'bad guys' who should be killed, GLaDOS's point of view is perfectly understandable: She is programed to be better at science than Black Mesa and without morals or ethics, even if flooding entire buildings with neurotoxins killing hundreds of scientist is the quickest/best/easiest option. I, for one, will be really looking forward to the sequel: Portal 2 Expand
  7. Sep 24, 2010
    Just great. I loved every single second of it. Played it through at least five times. It has mind-bending puzzles, hilarious dialog and just great graphics. Definitely one of the better Valve and PC titles ever created.
  8. Oct 15, 2010
    Up till now there is no better, funnier storyline in computer-gaming. A breath of fresh air among the hundreds of games all following the same paths, managers left and right to stop anyone being original.
    Portal dares and succeeds on all fronts. GlaDos may be borrowed, but Clarke's/Kubrick's HAL9000 never was THAT funny. Plus she was in love with me....(did she bake that cake?)
  9. Feb 3, 2011
    The Good: The writing is goddamn near perfect. The black humor, wonderful dialogue, and fantastic voice acting is perfect. The game mechanics work great, no glitches to speak of. The characterization of GLaDoS is great and make her (it?) my favorite game character. It's challenging, but not hard, the AI's decent, and the game is short, but that's good because it doesn't overstay it's welcome. The Bad:' know what? There's nothing bad about Portal. Seriously. The Ugly: No graphics issues to speak of. The games looks great. Expand

    10/10 = Masterpiece = I seriously want to delve into the minds of the developers at Valve. They are just geniuses. This game is seriously unbelievable.
  11. Nov 5, 2010
    This review contains spoilers, click expand to view. A very nice experiment of VALVe. I really enjoyed it. Loved the humor, loved the voice, loved the puzzles. Well yes, it's short. But there's a lot of levels made by community. And the archievements. And the advanced chambers. And cake. Cake is not a lie. Expand
  12. Nov 10, 2010
    i love this game. valve combined puzzles, humor, and an amazing enviroment into a delightful game. i admit, the game is damn short, but the game redeems itself, so for anybody who uses that as an excuse can shut up. i love valve and i cant wait for portal 2.
  13. Dec 30, 2010
    This game is the second best game I have ever played. It is quite short, but it is very fun and immersive. Can't wait for portal 2! Great addition to the orange box. 2000th review!
  14. Dec 9, 2010
    A boring start that is needed for any great puzzle game, so that is irrelevant. Once you get past a few you will be laughing your but off in the fun lonely adventure of the aperture science research facility! Another great product from valve.
  15. Dec 13, 2010
    This is a great, fun, innovative puzzle game that I though was going to just be a fun game. But when I played it, I was blown away by its brilliance. It was probably one of the best games that I have ever played in my entire life. It is well worth the price of $15(current price) and I would bye it even for $100. The only problem is that the game is just a bit to short, but Valve is making Portal 2 now and I'm sure that they will fix that problem in Portal 2. I would deffinetly go bye this game RIGHT NOW if I were you. Expand
  16. Dec 26, 2010
    This is a one of a kind, it's a pearl in the mist of mass killing shooter games and other FPS. It's the refreshing breeze in the desert of un-creativity (though short). It's the touch of jokes in a dead laboratory and it's the delicious chocolate that always leaves you starving...
    But of course you don't have to like chocolate.
  17. Jan 2, 2011
    Portal has solely raised my expectations in video game humor forever. The game mechanics are absolutely brilliant and have just begun to pave an exciting road to endless possibilities. I could play this game over and over.

    This review contains spoilers, click expand to view. Great game. Even if you have Portal 2 I would recommend playing the original Portal. After a challenging first run through the test chambers you are treated to (surprisingly interesting) developer commentary. Additionally, there are a number of bonus maps. While not everyone will like the game's humour, I did, and any motion sickness you may experience by travelling through the portals can be solved by limiting your game time to 2 hours or less. Disorientation and motion sickness caused by travelling through the portals is the only downside to this game in my view. For the game itself though, I rate it 10/10. Expand
  19. Feb 3, 2011
    The game took me by surprise! I didn't expect that much entertainment and joy from a puzzle game! The 1st instant i started playing i became fan of portal! The way u could use surrounding and items around is something new!
  20. Nov 9, 2011
    I bought this only recently on Steam... and man, this game is pretty damn good.
    Graphics: early HL2 engine, hairy muff. - pretty good for the age (now a few years old)
    Concept: 3D puzzle ... ... (but not a shooter)... you just get a portal gun which makes. Portals!
    Everyone is getting off from the concept, but I really loved the "story", which seems to be taken somehow from 2001; space
    odyssey (HAL).

    It is fairly short, finished the story in only two days. But, that said, the length felt just... "right". Just at around the time that the portal puzzles were getting old- it managed to keep pace and move the story to the last segment of the game.
    There are bonus levels and puzzles so you can be entertained a bit longer...

    ... and.... one of the best end sequences Ive seen in an age!! WOOOOT!
  21. Mar 15, 2011
    This is one of the more innovative games I've played. The humour and wit make it so entertaining and the puzzles/quests are really interesting. I loved it and can't wait to play the second one. And who can complain about the end song? It's genius!
  22. Jul 5, 2011
    Pretty much the single best puzzle game I've played. Even its short length isn't enough for me to give this game anything less than a 10. Anyone who owns a PC needs to get this game. Every once and a while a game comes out that reminds you that real innovation can still happen. This is one of those games.
  23. Mar 14, 2011
    Portal is a challenging puzzle game from Valve. Valve is known for their fantastic, original games, and Portal is no exception. Each level is fun and creative, each puzzle unique. Portal does a fantastic job with slowly easing you into the game play, instead of forcing you to jump off the deep end. In addition to the fun puzzles, Portal keeps you entertained with the humorous commentary by GLaDOS, one of the best villains in videogame history. Although the story is short, most likely will take from 3-5 hours, depending how fast you catch on, there are a few different modes to choose from. In addition to the Developers commentary, there are separate challenges (such as least portals and least steps) for each puzzle. Finally, you can always play your fellow Portal Player map creations. In the end, this game is a must-buy for all gamers, even if you dislike puzzle games. Expand

    I heard so much about this game that i had to try it. i bought it off steam for $9 and considering that i enjoyed this as much if not more than most AAA games yet paid less than a standard Xbox arcade game blows me away. i could not find a single flaw, i had a few audio glitches while playing on my mac but overall the graphics are still great and has no game play flaws that i could find at this price. Expand
  25. Apr 19, 2011
    Probably my favorite game I've ever played. Funny, emotional, puzzling, and really fun. There is also a great sense of mystery to the game that makes it really fun to play at 2:00 in the morning. Portal proves that a video game can be art.
  26. Apr 20, 2011
    Easily the best action puzzle game Iâ
  27. Apr 27, 2011
    Portal was truly an amazing game. First of all i think we have to remember that although a great game, it wasn't meant to be the hit of the Orange Box. It was originally created as a fall bac game just in case the rest of the Orange Box didn't do very well. Besides that, it was an amazingly innovative game that made up for its lack of length and difficulty with its humour and game-play. I loved the game myself and wouldn't have changed a thing. Good job Valve. Expand
  28. May 9, 2011
    Portal is a great concept, brilliantly executed. Wonderful, intuitive puzzle design, a great visual aesthetic, and some of the funniest dark humor narration you could want. Short but there's not a bad moment to be found and the price is low!
  29. May 10, 2011
    Short, sweet, charismatic, funny, and teased my head for awhile. The perfect length and a great experience, highly recommended for anyone that can spare the 4 or so hours it takes to complete, it's well worth it.
  30. Dec 9, 2011
    When people saw the trailers for Portal, they knew it would be a fun mechanic, but nobody expected the amazingly engrossing character of GlaDOS. These two factors combine to make one of the most original PC games of all time.
  31. Jun 6, 2011
    I can not see why 39 people say this game is bad. I mean, if it's because the game is short, just get Portal 2. But Portal 1 is still awesome! Well, some people could say you could complete it in a day, but that's a lie, just like the cake. It can take up to 2 weeks to complete. I mean, I completed it in 4 days. But the challenges make wanna play it over and over!
  32. May 27, 2011
    While a short game, the high level of polish and wonderful humor have this game as a comparison point for almost all modern games to be held to. The style, level design, and humor come together to make a wonderful, easy to play (though sometimes hard to beat), enjoyable game.
  33. Jun 17, 2011
    The simplicity to this game in one aspect makes the story a little bit more disturbing and mysterious than its sequel. GLaDoS seems to be a glitching robotic system that has an unintentional desire to kill through her little glitches, which slowly evolves into an obvious artificial-intelligent insanity. The game is very well-made and is one of the best first-person puzzle games out there, and it's one of the best Valve games out there. The game is very short, but very fun. I can probably beat it in about half an hour and still have a great time doing it. The story is simple enough, but yes it has some very disturbing aspects about the implied history of the machine intelligence GLaDOS, and the portal system itself is very inventive and entertaining. This is a game you have to play at least once, just like it's sequel. Expand
  34. Jun 14, 2011
    this game is amazing. i notice that it is short, and im okay with that because it was just suposed to be a quick little game on the orange box so that people might ask for a sequel, all the other orange box games may be long but all of them were sequels, along with epic. this game is a full time puzzle game with some fun humor. all puzzle games once you think about are actually short, but finding out the puzzle is what makes it long. and does length really matter? if its a fun game then don't gripe about the game. it is fun. Expand

    Portal is one of the few games to exist in the industry that contains some genuine science fiction. Its an obvious opportunity of interactive games to create original science fiction but sadly is missing by most popular titles in the industry. Portals focus on good design and puzzle solving rather than the immaturity of violence and 'bad-ass'ness makes it stand out as intelligent from the dumb gaming crowd. Portal is funny, intelligent, flawlessly designed and does not over stay its welcome - the short length is by design and is a good thing. HIGHLY RECOMMENDED! Expand
  36. Jun 21, 2011
    Portal by Valve, was at first, nothing more than a test for the new physics system, now it has it's own sequel. Awesome graphics, outstanding gameplay, a great storyline, and a well thought out series of tests and challenges combine to make this ONE OF THE BEST GAMES EVER!!! I highly recommend it. It's money well spent.
  37. Jul 5, 2011
    Valve you did it again, you created a whole new idea to add you your arsenal are games this game along with portal 2 are just a must have must experience game worth the 50$ but i'm patience and waited for the summer sale 30$ =p
  38. Jul 15, 2011
    Portal introduced a brand new and exciting way to play games, and even though it was short, it has so much potential. The puzzles, dialogue, and of course, the song at the end can not make this a bad game. Valve still put a lot of effort into a game they were unsure about as they do with all of their games. The puzzles are somewhat hard at first but never frustrating, which makes the game so much fun to play again and again and again. It can be finished in 1-3 hours if you're smart, and maybe even half an hour, but there are challenges and acheivements you can complete, and of course, dozens of fan-made maps and mods. Valve just gave us a taste of this addictive cake, and we are still hungry for more, even after Portal 2, which accelerated the portal mechanic and gave it more power. Expand
  39. Jul 17, 2011
    Portal is a great Puzzle Game. The Puzzles are Great, The Graphics are better then the Sequel, the Humour is good. And it may be short but once you beat it you unlock Advanced Maps, these are alot more Challenging and add even more fun. Portal continues to provide you with fun even after you've beaten it. It's a great Game, but my only Complaint would be the fact it's very short

    Jul 25, 2011
    Yes, I realize Portal was very short. But I would rather have a quality game that lasts about six hours than a piece of trash that lasts 20. And Portal is one of the most innovative, funniest, and mind-numbing games you will ever play. The puzzles are challenging enough to be satisfying, but not so tough that they're impossible to solve. Add to that the dark humor of GLaDOS and the best video game song ever, and you've got an amazing game. Expand
  41. Jul 22, 2011
    This game is really short, but seriously, what a pleasure to play it.
    It's fun and inventive, incredibly, you need to think the first time you play it, I mean, you really need to think about how to resolve tests, not all of couse, but it is different of all this ultra-over-shooting games which are really boring.
  42. Jul 31, 2011
    This review contains spoilers, click expand to view. One of my favorite games of all time! Although it sounds like a stupid game if you explain it to someone that's never heard of Valve before, people really give it a chance. It' s a post-apocalyptic first-person puzzle game, about an old science research company, and you are one of the last humans after a hostel take-over of the evil robot/computer, GLaDOS, and are forced to complete a series of pointless puzzles, being promised a cake at the end, but finding out the hard way that it is a lie!I t's a great game! I really recommend it! Expand
  43. May 15, 2012
    Awesome idea! Enjoyed it. Taking into account that you have only one weapon (in essence) - making a such addictive gameplay is truly worth of praising, Valve! Thank you! :)
  44. Aug 13, 2011
    best game I have ever played. creative game play, nice puzzle design. plot is also good. but this game is a little short. Orange Box is really cheap though, I think everyone should play it.
  45. Dec 21, 2011
    I got this game for free after winning a Steam competition (Bonus!) and have already played through and finished Portal 2 so playing this game was really quite hard for me at first because of the high expectations I gave it but it quickly grew on me... Almost as fast as I finished it. After two hours I finished it and that does sound very short but I felt like it stayed just enough as not to outstay it's welcome, like when you let a hobo in your house on a rainy day and he leaves after a coffee and when the rain stops, unlike some games where the hobo would stay after the rain has stopped and refuses to leave until you're forced to enjoy his company before he actually decides to high-tail it! Overall, very fun game with lots of challenges along the way that I thoroughly enjoyed so I give it an amazing ten out of ten! Expand

    This review contains spoilers, click expand to view. I don't like bad things so let's clear them up now:
    It's too short: I kept waiting for training to end, but training is the game
    The last battle is too easy: the timer's for 6 minutes!

    That is all:

    This game is the best PC game ever!!!!
    Through the 2 hours that you play, GLaDOS will guide you through the test chambers, while trying to kill you, and you must solve puzzles, and in the end, escape Aperture laboratories.
    You can't deny the brilliance of this game...
    unless you like COD...
    from start to finish, so pick it up NOW.

    + Addictive as heck
    +Humour is great
    + COD lovers will go away
    -Its too short
    - Last battle disapoints

    Truly one of the best puzzle games ever with a good mix of humor sprinkled with a sense of urgency this game is mesmerizing. It draws you in and never lets go.

    When I found out that there is such a game called Portal i decided to try a demo version. After completing 2 levels all my doubts about buying it or no went all the way outta window. Next day i went to the store and bought it. Now I have the game 100 % completed, 50 hours spent playing it on Steam and one thing I can say - it is the work of genius. In fact, a crew of geniuses - Valve. What they managed to deliver here are unique atmosphere and puzzles that can challenge both newbies and hardcore sons'O'biches. Some people say - the game is f'n short. My answer is - try time, step and portal challenges and you'll see that you were wrong. The voice acting is brilliant, as it combines humor with sci-fi touched scary monologues. The story is great too - it has this you-didn't-expect-this hilarious moment. Some can say that it's not so cool when you play Portal for the 2nd, 3rd time - you already know what will happen. I think it would be great to have a memory eraser to play it like the first time. And, by the way, Portal gave birth to characters that are among the most popular in game industry now. You know who I'm talking about, monsters._) Expand

    Ellen McLain's performance in Portal 2 made her an instant hit with Valve fans. McLain shows an amazing talent with voice acting, and singing.

    Portal, itself showed gamers a new way of thinking. It was rare to see a game that was so much fun without shooting everything in sight, which made Portal different from a general game. The storyline is brilliant and clever. Portal wasn't too short
    at all. It wasn't a game - It was a test. A test that did so well it got itself an amazing sequel that sold millions of copies. Those who gave Portal 10 would agree - Portal is a game you will never forget. Even when your old and senile. Expand
  50. Sep 18, 2011
    This is probably one of the most creative games that will ever be put on the market.

    The game was not meant to be long, it was meant to be fun, and enjoyable throughout the whole game. Although many people complain about how short the game is, if you really think about it, there are more than 18 chambers in the game with some complex puzzle solving. The simplicity of the game is what
    makes it the best game there is out there, and now it's free, and if you don't own the orange box already, or you are thinking of buying portal alone, its definitely worth the money. But, if you are not willing to buy a game that is fairly short, you might wanna look into renting it. Well worth the money. Expand
  51. Oct 3, 2011
    This game is very entertaining. What sets it apart from all the other games is the simply beautiful graphics, the smooth gameplay, addictive story, and flawless concept!
  52. Oct 6, 2011
    A narrative, as well as a puzzler, Portal works on every level it's almost scary. It doesn't overstay its welcome, but it doesn't seemed rushed. A near perfect game.
  53. Jun 21, 2012
    Despite the Metacritic ratings; many of opinions I heard of Portal were mixed. Some said it was short, others complain of the linear level design and unspectacular graphics. Yes, Portal is only 2 hours long. Yes, the progression is linear. Yes, the Source engine graphics are not exactly Crysis. But ultimately, these factors actually contribute to why Portal is such a great game: it's tightly designed, well-executed and unique. Anyone who likes puzzle games or even video games in general should seek this out to see what all the fuss is about. Expand
  54. May 21, 2012
    An amazing and Innovative game, yeah its short but hell it has more fun then a lot of big games (CoD).
    GLaDOS is awesome and very funny, the puzzles aren't to easy but they are also not frustratingly hard.
    This is a must buy for anyone who hasn't played it yet and a could game to go back and play again.
  55. Mar 22, 2012
    Yes, it's short. No, it's not very challenging. This is in my top 3 favourite games of all time. The soundtrack, the mood, the story, the humour. I love it all, and the cake was delicious.
  56. May 10, 2012
    This review contains spoilers, click expand to view. One of my favourite games. The portal mechanics were unique and well-coded. The story was amazing. The cake became a meme for a reason. The extra levels were also really challenging and kept me playing it for a lot more time.

    What I never got into me is the companion cube. I burned the sucka the moment I was instructed to and never got in any way attached to it. Was I even supposed to get attached to it? Who cares anyway.
  57. Feb 9, 2012
    Games like Portal are not trying to have hundreds of hours that will mostly be uninteresting and mindless but hey, most of what's on TV is even worse. No, games like Portal instead make a very interesting experience, one that will make a real impact on your mind, rather than try to eat up lots of your time. And that's not even mentioning the downloadable maps and stuff which I'm sure by now is numerous.

    I downloaded it from Steam and gave it a shot. I was instantly intrigued by the game mechanics, for a variety of reasons. I highly recommend it. The puzzles aren't too difficult, I beat it in 6 hours and that's including the time I spent screwing around in infinite corridors for me to chase myself through, trying to save the companion cube and getting stuck for a few minutes here and there. Don't play it expecting something to kill time like it's an MMO or TV, just soak in the game mechanics because they are fascinating. In addition, the game does have some story, atmosphere and humor for you. Give it a shot.
  58. Jan 17, 2012
    Excellent puzzle game, the only game in first person as elaborate puzzle. It has a really interesting story and characters very striking (albeit few). The mechanics is playable spectacular and innovative portal system is very well done, thought with physical puzzles and portals at once. Graphically the game is not spectacular or anything, but meets a striking and interesting art section, although it is appreciated that the game is very well optimized for use over several sites at once. The cast of voices (even though limited only to the machines) is very well chosen, with humor and a story behind them very compelling. The sounds are very well made and is one of the games with the best soundtracks out there. This game is highly recommended, even if you have a short duration, is still a great game and giving for more (see Portal 2). Expand
  59. Mar 9, 2012
    Purely superior in experience to the 2nd portal in every way. Great story, great player engagement, great pace of introducing new ideas. After playing this one, the 2nd one felt redundant and the story felt incredibly forced. They changed their mind on where they were taking this game when they patched the end cutscene to change from you being free to being dragged back inside .. then sealed off the portal world from ever influencing the half-life world, which was very disappointing to say the least. That aside, a very fun game overall which I actually put probably about 20 or 30 hours into doing various advanced puzzles and repeating the game once or twice just because it was fun. Expand
  60. Jan 1, 2012
    Very fun to play game and i also liked how it got implemented in the half life universe instead of beeing released as completely new IP. Just get it, its not expensive and very worth to be played.
  61. Nov 15, 2013
    I think this game might be perfect. No, seriously, this might be a perfect game. It is so well balanced, and the plot is perfectly integrated with the gameplay. I like it better than the sequel, to tell you the truth. But it may be that the multiplayer in Portal 2 is what puts that game ahead.

    Anyway, I think this game is a must for any serious gamer. period.

  63. Jan 3, 2012
    The best game made since Tetris. Surreal, complex, with all the goodies of an indie but the backing of (who else?) Valve, all but devoid of violence, with elements of sarcastic dark humor and relaxing cuteness mixed with fearful suspense and tongue-in-cheek moments of LoLs for a story you really have to dig at to comprehend. Short, yes, but there's only so much you can do without either becoming repetitive, becoming repetitive, or throwing the average and below players at a brick wall and saying "climb." Voice acting is all done by one person if you can believe that, and the song at the end is the very definition of a cult classic. And as Yahtzee said in his review of the sequel, the only real complain that exists is the annoying fanbase who can't keep their grubby little paws off of something in order to keep it sacred. Hobbes was right. Expand

    Portal really surprise me by showing me the new way and new concept of gaming. Yes, the game is really short, but it is never repeats itself. I know people would say other games are longer, and stuffs, but ask yourself, you do the same thing over and over again (Lvling, farming, fighting the same kind enemies over and over, you get it.) and that is why they are longer. Great humour in the game too. I always enjoy the sarcasm in the game. Good job to the team. You guys made a game that deserves 10/10. Expand

    If the score of a game is an indication of how much of an impression it made on you, I think most would agree Portal ranks at the top. Writing comedy is hard, and finding such memorable and hilarious comedy in a video game is incredibly rare. The fact that Portal manages to contain just that, while being highly original and thought-provoking, demonstrates just what a work of genius it is. If any game can be held up as an example of art, this is it. Valve are the masters at creating compelling and immersive environments- and the setting of Aperture can easily feel real. GLaDOS is the perfect example of how fantastic writing and acting can create a beloved character. Portal is gaming at its finest- truly a genre-defining title, and one that will leave the player both wanting and satisfied at its conclusion. Expand

    Eight hours of pure fun. Short and sweet. It's cheap and you'll love it. Grab it. How to describe it? It is a puzzle game. It doesn't take itself too seriously and it has an excellent sense of humour. GET IT.

    This review was meant for Dear Esther: Portal 2 was a hight 10 for me I LOVE Portal 2. Dear Esther was a low 1 for me. Did not enjoy Dear Esther. Waste of my time sorry. I felt the potential for this game to be almost what Myst was when it first started that genre of story driven games. However, I very quickly found myself bored and I love English accent narrations especially but it wasn't enough to hold me to the end. I found myself aimlessly wandering around. I couldn't pick up anything nor save the game. Not for me this game had potential it was beautiful the scenery.â Expand

    This simply is a great game the story is simple and funny but still quite strong it doesn't go on for to long and the mechanics themselves feel refreshing unlike the stale mass produced FPS games that are released on a monthly bases. This game never bored me and it actually is one of few none strategy/fight/race/etc. games that actually made me feel like replaying it (far) more than just once. Even tough the levels are quite small it gave a huge feeling of freedom because the rooms just seemed infinitely bigger when you were allowed to portal trough them. For those who are done playing the original levels there still are a lot of player made levels that grant an even bigger (or lesser) challenge. Expand

    For me, this game is better than Portal 2, because even as a small game, he has a great story, but the game is kind of easy. Only the Advanced Chambers, in the Bonus Maps, are more difficult.

    Valve have always treated PC games to the best in gaming entertainment. Now arrives a new IP from the studio's responsible for Half-Life. Portal is a 90 minute first person puzzle game set in the remains of Aperture Science, Black Mesa's only rival in the realms of science. You play Chell, the only remaining test subject for the Aperture Science Handheld Portal Device, or in layman's terms the Portal gun. As you are set to complete test chambers created by GLaDOS, the corrupt computer program running Aperture. Chell must escape Aperture and destroy GLaDOS to make sure these experiments never continue. It plays like any Valve FPS and looks like Half-Life 2 but a lot more sterile (white). Portal is one of those rare gems that come around every now and again (usually from Valve) that change the way games work, they change the way games are seen and they change the way games are played. Portal is one in a million. Expand

    In my humble opinion Portal represents the pinnacle of game design. With it's utterly unique and creative game mechanics, and intelligent level designs, Portal proves that a puzzle game can be much more enjoyable than the horde of First Person Shooters that dominate the gaming industry.
  72. Apr 15, 2012
    If finished the game at least 5 times, it is short but very fun to play. Getting the achievments is also very funny. The game itself may be short, but there are many mods available like e.g. portal prelude, which steps the difficulty up, many custom maps etc etc so you get unlimited play time! The portal concept was very innovative and it's so much fun to play!
  73. May 10, 2012
    This game is why limited budgets and resources can create games of the highest quality. It's clear that we had a motivated and passionate team who poured their very hearts and souls into this game. They didn't waste resources on useless garbage. The Tutorial IS the gameplay. The story isn't played through boring cutscenes, you interact while the story is conveyed to you by the antagonist, a hilarious AI.
    The gameplay is amazing and the physics are just stunning. I could not find a way to describe it..

    This is revolutionary and simple. Hardcore gamers and Casual gamers will love this game. After this experience you will be buying all Valve games.
  74. May 19, 2012
    Portal is an amazing game with astoundingly innovative gameplay. It may be short, but it makes up for that with progressive difficulty and good humour.
  75. Jun 13, 2012
    Portal is a puzzle game like no other, set in a world that seems to defy the odds. You will work your way through twenty something puzzles and discover the world you think you know, is nothing compared to what it really is. It's ingenious and really makes you think in order to progress. If you can think outside of the box you can pass through this game easily while learning about the world around you. Expand
  76. Jun 18, 2012
    though the game is incredibly short; it is still impressive. The puzzle's will keep you busy and the cruel humored GlaDoS will keep you entertained. the graphics are your typical valve graphics powered by source.

    Even though it has indeed been quite a few years now since I first ever played this game at a friend's house, followed IMMEDIATELY by me purchasing it for myself to play on MY computer, my love for the original "Portal" game has not diminished even a single bit!!! I can still so EASILY remember how unbelievably quick I was to become completely engrossed in this "first-of-its-kind" game-play. I even went so far as to try by best at brainwashing my own father into playing it. (And much to my surprise, he gave it a try after watching me play a bit on my PC, and of course, quickly came to love it every bit as much as I.) Add to that list my own younger brother, who was and is still a hardcore "console" player. Sure enough though, as soon as he found it available for purchase on the X-Box 360, he was up all night long playing it as well. In conclusion, I would very much like to also add-in the factor of this beautiful game's UNBELIEVABLE "RE-PLAY" value. I've not ever kept any official count or anything, but it I had to guess, I am quite comfortable in guessing that I've played back though the same game again, over and over, trying new and different techniques each and every time, no less that a few hundred times within the past few years. :) To some, that fact will no doubt just appear stupid, and easily a target for such words as "has no life", "still living at home with Mom", etc... It's OK though, because, to all the rest out there who ALSO fell in love with Portal years ago, YOU no-doubt "understand". :) Expand

    Innovation at it's finest. Portal provides much humor and action, something that is very elusive from writers, designers, developers, and creators alike. It is very challenging too. Anyone who doesn't like it can't use their damn brain. It's a damn humorous puzzle action story so **** YOU!
  79. Aug 7, 2012
    Awesome game. Introduces an amazing concept, story, and all around style to the world of gaming. The only con I can think of is the fan base. All of the **** running around saying, "LOL the cake is a lie guys amiright!!!" But you cant blame the developers for that. And to the ass hats complaining it was so short? This game was made by a small team within valve. It was just padding for The Orange Box, and kind of an apology present for half life 2: episode 2 being delayed. It was never expected to explode like it did. Even thought it was only a couple hours, those hours were some of the best of my gaming life. Expand
  80. Aug 12, 2012
    Easily one of my favorite games of all time. Simple yet addicting game mechanics form unique and memorable puzzles and make a solid foundation for the subtly unfolding story line.
  81. Aug 20, 2012
    We all must keep in mind that this game was hidden behind TF2 and HL2 in the orange box, and yet, it still managed to make a name for itself and generate an enormous fanbase. Valve, once again, delivered an excellent and original idea when coming up with the revolutionary 'portal gun.' This game wasn't necessarily meant to be stand-alone, so those people who are saying that it's too short, keep that in mind. Also remember that it's only $10 dollars at the most, and that's $10 dollars well spent! I bought it on sale and wish I would have payed more. It's a puzzle that makes you think and provides a little clever humor. So, of course, I give this a 10, because I feel that it was one of the most original ideas and revolutionary designs of it's time, and it set up for an interesting and intriguing sequel. And while most games are $50 upwards nowadays and some hang around $20 for up to 5-7 years after their release, Portal is $10 dollars and is affordable fun for those of us who have low-end PCs and don't want to spend too much money. That's just another positive towards this amazing game. Expand

    it is a awesome game! sure it's not a long game that will take days to complete, but you never gets tired on it (at least not me) and It's great when you finished the story, you can play like minigames, complete the maps with times, footsteps and portals, so as I said, I never get tired on this game
  83. Nov 24, 2012
    Extremely fun and charming. This game is a classic that must be played. Yeah, it may be short, but for a $3 game that any computer can run, you should not miss out on this
  84. Oct 10, 2012
    Great game! Good fun for a few hours, many people I know love this game and have played it through. This includes people normally adverse to computer gaming. The game is very short but for the price its worth it!
  85. Sep 28, 2012
    Well, I'm late on this review. But this is one of the best games of all time. I love Valve, and 99% of all of their games.
    Valve puts time into their games and aren't lazy developers. 10/10!
  86. Mar 22, 2013
    I came upon this game totally on accident before it blew up and boy was I surprised. To this day, still the single greatest initial gaming experience I've had. The intrigue, the suspense, endless curiosity and then shock and surprise. What a twist!
  87. Jul 29, 2013
    A great game with excellent innovative idea. Some of the puzzle rooms are simply a work of a genius. One of the best puzzle games ever. If you haven't seen it, you should.
  88. Nov 5, 2012
    Portal is a puzzle game using portal physics. It's very basic, but very polished. The puzzles can get pretty challenging but satisfying, and you are rewarded further with an interesting storyline packed with witty humor. It's hard to believe that Valve just threw it together. My only discrepancy with the game is that it ends, and for that reason I give it a solid 10.
  89. Nov 16, 2012
    This game should be in the top of the 5 best games of history. It has no amazing graphics, the control *in theory* is simple and the argument isn´t very exciting.. But it´s so enjoyable to pass the different zones, using your brain all you can. I haven´t finish this game yet, but 2 hours of playing say all about it.
  90. Nov 18, 2012
    This game is funny, this game has a great storyline, the game looks good, overall this game is awesome. i like how this game has its own style. i love this game. i finished it like 3 times, and i still can't get enough of it! It's definitly worth the low price.
  91. Jan 26, 2013
    After The Great Half Life 2 episodes and the God Like TF2 i was expecting a bleh of a game with portal. I was as wrong as thinking a minute was 100 seconds when i was a kid. The Portal concept was fun and puzzling. Using the companion cube and valve nice physic engine was a joy to play through. The story was immersing and had some of the best humor ive ever heard. And the the extra downloadable maps are the icing on the ca.. i mean french fancy. Portal was the best 2 hours ive spent in my life. This game is my number 6 game of all time. Then Portal 2 was a knock off piece of **** Expand
  92. Nov 28, 2012
    The perfect game. Among the top 3 to play before you die. The immense gratification you'll experience once you're successfully "thinking with portals" is beyond words. My review therefore stops here. Play it!
  93. Nov 28, 2012
    In first play i think was a game is too lazy, but two years later i play in Portal and can't take words about amazing feelings from this game. Play in Portal bring me back into my childhood.
  94. Dec 20, 2012
    A puzzle game with about 2 to 3 hours of gameplay. I am not a puzzle gamer though I enjoyed it because the puzzle challenge was doable and short enough before I start going asdjf;alsdjf;las on my keyboard. So if you are looking for a game that is different to what you normally play, pick this up when it goes on sale.
  95. Oct 28, 2013
    Love it. Quirky. Fun. Challenging. And of course very different thanks to the whole portals scheme itself. Definitely one of my all-time favorites and would recommend this to anyone.
  96. Dec 8, 2012
    Incredible game! The concept is great with a huge potential and it's really fun to play!
    Even after finishing it, I still enjoy to play it again.
    A must-have.
  97. Feb 13, 2013
    The central concept of Portal--linking a world to itself through a portal--is simply brilliant. The game offers many fun, physics-based puzzles. Some dark humor completes the experience.
  98. Feb 26, 2013

    yes its only 2-3 hours long and I managed to speed run it at exactly 27 Minutes 16 Seconds but how did that guy get 13 minutes and 28 seconds but anyway all the puzzles are interesting and imaginitive GlaDos is amazing and the humor as well but the sequel did better in that category but I prefer the first one its feels more alien and different its really cheap on Steam so buy it and if you don't have a PC why are you reading this then get the ornage box or on the 360 get Portal:Still Alive Expand

    The idea behind Portal ends up being more brilliant than Portal itself. Regardless, we definitely had a lot of fun with what is there and appreciate the level of polish and thought that went into the presentation.
  2. Portal is a magnificent puzzle game. The titillating wrongness of every solution and the wonky thinking required to get there make you feel like a space-folding genius, and yet you'll almost never get stuck.
  3. One of the most interesting and delightful things Valve's ever done, but also one of its least fulfilling. If only we had our own portal gun to bridge the gap to the first infusion of new content, perhaps we could forget it.
