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.

Oh how I wish Valve would make more single player games they're good at it

Don't get me wrong Valve's multiplayer games are just as good BUT REALLY VALVE IS AMAZING AT making single player games but sadly There will be no more games from valve single player or multiplayer

But portal is a amazing game.

9.9/10
Why 9.9 you might ask Because I really wanted that cake.


Oh and I became gay for a cube.

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.

Everything that you've heard about 'Portal' is true. Well, if you've heard nothing but great things about it, that is. Because this is easily one of the greatest puzzle games to ever be created. Hell, it may even be one of the greatest games created, period. It's like 'Half Life 2' but on crack! You thought crack was bad for you, didn't you? Well it turns out that crack is good when combined with elements of puzzle solving and first person shooters.

'Portal' may be short, but it's pretty damn cheap too. And when you take into consideration the difficulty of the added challenges after you've completed the story, it should take a decent amount of time to complete.

Nevertheless, it's refreshing to see a first person 'shooter' without bullets and if you haven't picked this game up that's something that you should probably be doing right about now.

The Portal games were two of the games that I already owned on the xbox that I found worthy enough to purchase again on steam. Both games are quite wonderful, and are equally deserving of a playthrough.

Pros
+ The graphics are a bit dated in terms of newer games, but look wonderful for their age, and run smoothly on most machines. I will sacrifice top notch graphics for playability any day, and this game doesnt make you sacrifice either.
+ Voice acting is strong, clear, and adds another layer of awesome for this game.
+ The game is a puzzle platformer game with enough challenge to give your brain a workout, but not difficult enough to make you want to throw your laptop out of a window.
+ It has GLaDOS in the game. I put this under pro simply because her commentary throughout the game is hillarious.
+ The game has achievements. Pretty self explanatory.

Cons
- There is little replayability for this game, other than to hear GLaDOS speak.
- I experienced some crashes at inopportune times, but could not figure out if it was a hardware conflict, or something else.

Final Thoughts

All in all, this is one of the most fun games that I've ever played. The humor used within the game is right up my alley, and the game itself runs well and gives me enough of a challenge to feel satisfied after playing it. I do feel that most games this old aren't worth the full price on Steam, but this game is an exception- largely due to the amusement factor. I would rate this game an 8/10.

I will be brief: I downloaded demo and played for 5 minutes. Then I removed it, went to the store and bought Portal 1-2 bundle. That same f'n day - 16 of July, 2011. The consequences: 50+ hours, all challenges done and the place earned in my digital heart for ever.

The first Portal is for sure shorter, has less story and features than the sequel. Though it has something... the mistery, the charm, the feel of menace, elegant sci-fi scent and terrific GLaDOS who hasn't went over the top yet. Valve, put your sorry Dota 2 down and please make games like this.

It may be short, but boy is it sweet. Portal is one of those rare, perfect games.

Playing through Portal, you'll be treated to delightfully subversive dark humor, which slowly gives way to a creepy, sinister atmosphere. The gameplay is rock-solid, too - challenging, but not unfair to the player. And without spoiling anything I can tell you that Portal has one of the best video game characters this side of 2000.

Long after you've finished it, this game will stick with you.

An eerie sci-fi, first person, physics puzzle game, Portal is the spin-off series to Half-Life taking place in the same universe.

----
Overview
Taking place in Aperture Science laboratories -the Enrichment Center- you are a test subject awakened from suspension state for testing purposes. You are given the Aperture Science Handheld Portal Device to take place in the physics experiment, though the plot unravels to reveal a darker truth to the facilities.

Gameplay
Playing Portal on the first time can be admittedly disorienting, but the player progressively adapts to the puzzling nature of the portals and the Device throughout the test chambers. Dealing with test elements such as moving platforms, high-energy pellets, AI turrets and acid pits, each chamber is challenging in its own manner.

You can also try the extra challenges in the game for bragging rights and achievements.

Plot
While relatively shallow, the plot of the original Portal game has a certain degree of paranoia fuel and space for imagination of what's manipulating the experiment and the nature of the Enrichment Center. Combined with the ARG and further content ('Lab Rat' comic, among others), the game lore is carried forward and somewhat explained of how it fits within the Half-Life universe, leading into the events of the sequel.

Graphics
Decent level of detail for a puzzle game, and low performance required make this game worth a try for even older machines.

Sound
The soundtrack of Kelly Bailey, composer of the Half-Life series has the uncanny feeling of both sinister, outworldish experience that Aperture Science becomes to the player, helping the immersion into the strange world of Aperture.
The sound effects in the game are fitting to the setting, mainly consisting of sci-fi noises and mechanical machinery. Few audio errors are noticeable if any.
----

TL;DR: A strange puzzle game that proves a challenging experience eventually brings you deeper into the lore of Aperture Science, a fairly enjoyable game with a great sequel and setting.

A game where you are a lab rat for a crazy AI who makes you do experiments in exchange for a vague promise of cake.

Play it. Because cake is yummy!

Portal is a magnificent puzzle game. The titillating wrongness of every solution and the "JUSTNOIDEA" thinking required to get there make you feel like a space-folding genius, and yet you'll almost never get stuck. Skilled players will portal their way through the nineteen levels in just a few hours, but this little puzzle game / tech demo provides plenty of entertainment and makes a great addition to The Orange Box. WHICH IS AWESOME :D BUT NOT CO-OP THOUGH , ONLY SINGLEPLAYER . 10/10

Cake is served.
Released as part of Valve Corporation's 'Orange Box' bundle of new and old games, Portal is a first-person puzzle game set in the sterile test chambers of Aperture Laboratories. As the silent protagonist Chell, you are given no expository cutscenes or dialogue prior to the commencement of gameplay—you are simply told to complete the tests, and you have no choice but to do so.

The lack of exposition in Portal is the first of many things the title does right. You start the game with no knowledge of what's going on besides the seemingly pre-recorded monologue of GLaDOS, the hilariously sarcastic and antagonistic AI controlling the entire facility. Throughout Portal's story, there are increasingly intriguing hints to what's occurred within Aperture, but it's never stated outright at any point in the game. The primary narrative of Portal is very simple when put to paper, but the secondary, hidden layer of story beneath is what makes the game interesting. You don't even have to read into all the hints and figure out the whole story to appreciate this. Portal's light tone contrasts with the dark, violent story being told off-screen, and it brings the game's atmosphere above the average and propels it into a subtly executed masterpiece.

Portal doesn't allow itself to be carried by it's superior atmosphere and non-traditional storytelling. The Source engine seems to have been designed to bring us Aperture Laboratories, and every level and section is put together in a cohesive way that makes sense. This goes beyond the test chambers into the maintenance and offices of Aperture, where it feels more like a game level constructed around an existing facility rather than the other way around. Several notable sections in the second half of the game take you through the offices of Aperture employees, which have windows overlooking the test chambers you completed several levels back, in which you saw the blurred-out windows on the walls. This sense that you're in an actual underground laboratory really makes you want to explore, an urge which very few games can give you without providing open worlds filled with missions.

On the gameplay front, Portal takes a unique idea in the form of it's portal gun and provides puzzles that give you exactly the thought process that any good puzzle should. Initially coming into a large, complicated test chamber, you'll feel overwhelmed by the complexity, but as you chip away at the conundrum, you'll gradually work your way towards a solution. Portal doesn't reward you hugely for solving difficult puzzles, it simply gives you some lines from GLaDOS and an elevator to the next test. The reward is in the feeling of elation that only a tough puzzle can give.

When it comes to puzzle games, Portal is beyond question the most creative experience I've had to date. Not only that, but it also provides concise, elegant level design and a multi-layered darkly humorous story that just adds to what makes Portal great.
