About This Game

Portal™ is a new single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay.

The game is designed to change the way players approach, manipulate, and surmise the possibilities in a given environment; similar to how Half-Life® 2's Gravity Gun innovated new ways to leverage an object in any given situation.

Players must solve physical puzzles and challenges by opening portals to maneuvering objects, and themselves, through space.

"The cake is a lie!"

It is, but Portal does not lie as it truly is a good game! While short, its puzzles make it an interesting game so much so that you'd immediately want to do a 2nd walkthrough. Also, there is a way to replay several of the so-called "chambers" but in a more difficult version.

I'm not sure if this has mods like its sequel - nevertheless, it's worth completing this one before moving on to the next as the puzzles are even more difficult and diverse in Portal 2.

I like how the game has a background story while it would not be necessary, at all. It has an excellent antagonist in the form of an A.I. called GLaDOS.

Portal is a memorable experience and if you liked Half-Life you should pick up this Valve product, as well.

Oh, you didn't like Half-Life? Then, please go and have a cake. :)

PS: I'm not sure why I have zero hours logged for this game. Probably because the logging system was introduced after I completed Portal. In any case, my review is based on a gameplay time of roughly 15-20 hours.

Portal is definitely a one-of-a-kind. It's quirky at best, but it also remains clever, resolute and perfectly presented to those with a quick-wit and a scientific explanation for including physics in a well-thought out and intelligent game, all with a touch of dark humour.

You awaken in the deserted Enrichment Center of Aperture Laboratories; a fictional science research corporation, located in the Upper Peninsula of Michigan. Known for the creation of the handheld portal gun, as well as the heavy rivalry the complex has between the Black Mesa Research Facility. (The scientific complex focused in Half-Life. Half-Life and Portal both share the same universe.) in Portal, you play as the silent protagonist, Chell, from a first-person perspective as you are challenged to navigate through a series of cryptic chambers, all the while being accompanied by the voice of the Genetic Lifeform and Disk Operating System (GlaDOS for short.) which the sociopathic robot subsequently reveals the rest of the plot to the player, through various and long-winded narration throughout the game.

What strikes me most surprised is this game's ingenius concept and profound knowledge of linear momentum and physics. Your only weapon in the game, if you can call it a weapon, is the Aperture Science Handheld Portal Device. It's main and only ability is to create two distinct portals, an orange and blue portal, which both create a visual and physical connection between two different locations in three-dimensional space. Keep in mind that neither portal are both an entrance or an exit; all objects that travel through one portal will exit through the other. This unique concept will soon be taken to the test, as you explore, solve and escape through 19 mind-wrecking chambers. And what is this reward you get for all this mind-wrecking work? Why it's none other than cake!

While on the subject of sweet chocolate butter-milk frosting, assembled with maraschino cherries on top, this all turns out to be a crude lie, and you're sent to be burnt to a crisp by GlaDOS. As you narrowly escape death, you navigate through the many things that Aperture Laboratories would have wanted to keep as a secret to the rest of the world. You soon (or later, as this game has a way of messing with your head.) find yourself exploring the air vents, the sewers of the facility, as well as the abandoned, deserted offices of those who mysteriously left, along with empty food supplies and crude drawings that uncovers a much darker history of the Laboratories.

But you're not alone in this deranged prison of a laboratory, your square-buddy (and probably only buddy) known as the Companion Cube, will accompany you throughout a few of these chambers, as it has a handful of most needed traits; involving you using it as an extra step for those hard-to-reach places, using it as a shield against deadly lazer spheres and deflecting them into switch mechanisms, and even going as so far to hold out weight-activated button switches. Sadly, with every chamber completed thanks to your Companion Cube, you will have to eventually abandon it and leave it for trash, in the Emergency Intelligence Incinerator. What a true friend to the end!

When cracking down to the lifespan of this game's story, it's actually pretty short. But, with each new chamber you progress through as well as the differculty beginning to rise at a much faster pace, the longer the chambers will begin to mess with your head and could leave you stuck for a good couple of hours, stumped. I'm guilty to say that I even needed a walkthrough to deal with a couple of these cryptic and twisted chambers. But then again, that really ruined the experience for me a little, considering I like to figure things out much more independently. So, if you can unwrap things around your mind quick and efficiently, you may experience the amazement and ingenuity for yourself. I'm pretty jealous in fact!

This game is a massive recommendation for me, the scientific aspect of portal and three-dimensional space used in this game is best described as baffling. Valve must have been truly blessed to ever release this game, as it touched the hearts of kids, adults and professional scientists alike.

Excellent, unique, creative, and amusing. It's both challenging enough puzzles to be interesting, and short enough to not be tedious. Just like this review.

Set in an old and abandoned Apple store from hell, Portal is the game that you think it's as easy as it sounds at first, but then realize you feel like an idiot for thinking that the levels are impossible when really you could clear them in a few minutes each. You're promised a cake from Valve's idea of if Shodan from System Shock 2 and HAL 9000 had a baby girl and almost die for it

the only con to this game is that it's too *&%^$(! short

One of the Few games that manage to creep me out, even though it wasn't a Horror game... In Portal, you (Chell) have been ordered to complete Tests for your Garenteed, Safe, Exit by GLADoS. You feel so alone in the Test Chambers, although you have GLADoS speaking to you, (They feel like Old recordings..) you still have that alone feeling.. Until you meet the Companion Cube.. You'll see what I mean soon enough.. Apart from the Rattman Dens, and the Creepy Turrets.. This game is truly a Masterpiece!

I finally completed Portal. I dont really know why it took me so many years to play this game, but i dont regret buying it.
Great storyline and very interesting puzzles that create something that blows your mind. I definitely gonna start its sequel soon, but i totally going to finish this one more time. Definitely worth buying.

Short Verdict: A great puzzle game strongly based on spatial orientation, physics and some platforming. If you don't know it already, the basic premise is having a gun capable of shooting two portals, between which you can travel to solve puzzles. Portal is a classic and, as you'll see below, I can hardly say anything bad about it. You should at least try it (there's a demo available, or so it seems)!

Pros:
  • Smart puzzles, with great balance between pure thinking and skills (a bit too much on the skills side for my personal taste, but I wouldn't say it's a con)
  • Great atmosphere that builds up throughout the game
  • Fun side-quests, like finding radios and taking them to the right spot, and also putting down security cameras
  • Even has advanced levels and challenges for hardcore players

Cons:
  • Apart from Least Portals, I couldn't find challenges any fun, especially the Least Steps challenge.
  • Carrying objects around is slightly too clumsy. For instance, I'd like to be able to rotate what I'm carrying.

Bought on: Got it as a gift from Xsesis! Thanks a lot! It's been as cheap as US$ 1.99 (or R$ 3,99) on Steam. That's a steal! Definitely worth more.

Portal is a very interesting game, your given a gun, and your main goal is to complete all the tests chambers with that gun, without getting killed, therefore you will earn yourself cake The cake is a lie! . Portal has it's pros and cons, some of which are the concept is absoulutley...AMAZING! You will probably never see a game like this again, so it's best to get your hands on it. The music? There is none....just kidding, beat the game and you will find yourself one of the best songs you will ever hear. This game is actually kind of scary too, some of the sound effects and looks, can give you the spooks, and that's more in Portal 2 though, since it has creepy looks at the beginning, loud noises and all the goodies you could imagine. Here's the bad part, theres only about 3 hours of gameplay. If your looking to get all the achievements, it's right around 30 hours, and theres only like 12? 13? They're ridiculously hard. Some of them, requires you to move 2 steps. HOW IN THE WORLD DO YOU DO THAT? Yea, the achievements are hard. Second game? Theres 1 achievement thats tough, get 1 friend who's NEVER done co-op before, it can be tricky, but it's still worth it. Both games are filled with story. If there was a third one, I'd totally get it, without a hesitation.

Portal is a unique and mind-bending experience that I am so grateful to have the chance to play. There aren't many people who don't know this game or haven't played it. If you haven't already got this game I urge you to get your card out and buy it straight away. It's a one of a kind and with the sequel being even more astonishing it is definetly worth the money. From the iconic ending, which has one of the most catchiest songs I have ever listened to, to the briliant and hilarious dialogue. It is simply a masterpiece!

However, there are times where it can feel a tiny bit repetitive and a bit too hard for most average people like me. But it will never stop you from wanting more and it will never stop you from having a briliant experience.

9.5/10
Truly one of the greatest games I have ever played.

A game I just finished roughly in about 2 - 3 hours (the difference being all the "figuring out" time), Portal is a game certainly worth owning.

This is from a person who blindly bought Portal 2 without any prior knowledge of its earlier surprise success or without the imagination necessary to fathom how "portal mechanics" in of itself, without any other additive, be a good game.
Though I enjoyed the pacing, character dynamics, and indirect indie movie-like world building in Portal 2 more, going back to see how it all began will help explain particular jokes and flesh out many of GlaDOS's warped programming. If there's one complaint about Portal it's that, yes, it's a bit short even if for $10 but it's not like you aren't gettiing your entertainment/experience value and its chock full of special features for further insight if that's your sorta thing (it is to me!)

One complaint that might not bother others but sorta bothered me - again because I'm comparing it to 2 instead of vice versa - is that the game wastes no time piling complexity at you versus in #2 how it could often blend world building and exploration more frequently. It's a case of tight budgeting vs. free property reign but I feel it should be addressed.

All in all, Portal again cements Valve's rep at never offering inept neurally challenged games. Believe the hype or challenge it, either way, playing any entry from the series will add something you'll cherish in your life.

One of the best first person games ever made in the history of video gaming. Amazing idea which was executed brilliantly. A completely different approach to puzzles which requires a lot of thinking and patience of course. Don't waste your time on walkthroughs. That's the beauty of this game. You might spend hours on some test chambers but trust me, this game's worth every second you spend on it. Puzzles have never been so fun.

10/10 will shoot portals again.

First, I have to tell you something. If you have played Portal 2 before this (like me). Go, run and buy this masterpiece! This game is the origin of one of my favorite games (Portal 2). What can I say about this? Well, the game is very very short, but is still awesome! Have extra challenge maps and more extra fun which will blow your mind. Is very funny try to get all the archievements. And remember something...the cake is a lie!
