Third party DRM: Steam

This game requires a free Steam account to play.


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.

Through the Looking Glass

Portal shows a new side to fps games. Can this even be called fps? It would be more like a first person puzzle platformer aka fppp.

The player uses a portal gun which fires two different "doors" or "holes" in supportable surfaces that are connected like a wormhole through space. An AI will guide the player through different test rooms and quips against human intelligence. Soon enough, it becomes evident that there is also something else than testing going on in the facility...

The puzzles are not too tough but they are creative. Portal physics are fun to play with but it feels like the game doesn't get going until two thirds to the game and could indeed pressure the brain a bit more to my tastes.

Anyway, recommended to anyone.


An instant Classic

I first played this game without any knowledge of the story, characters, or other details of the Half-Life universe. The way the story carefully unfolded itself through the lovingly crafted puzzles was an awesome thing to experience: it's clear that each test chamber was designed to confuse you just enough so that you feel like a genius when you solve it. I've played many puzzle games, some frustrating and others rewarding, but Portal pushes all of the the right buttons (no pun intended) and delivers an excellent cohesion of atmosphere and puzzle solving. Definitely give it a play if you like well-crafted puzzles!


An Impressive Game

Portal has left my mouth open, amazed by the originality, creativity and innovation of this Valve´s project, the gameplay is moderate and invites the gamers to manage their actions cleverly and, somehow, to develop their mental skills with that powerful tool of physics. Is a clever game and is inspired by the Newton's first law, inertia. Is a very strange game, with a rare but and enveloping history, and also, a great achievement for Valve as a good game for the gamer's collection.

Portal is one of the most interesting games Valve has released. It puts you in the shoes (or rather, Long Fall Boots) of Chell, a test subject in the mysterious Aperture Science laboratories, a rival company to Half-Life's Black Mesa.

In this game, you won't do a lot of fighting. Armed only with a Portal Gun, which you can use to make your way through the testing areas, you'll slowly uncover what happened to the facility, while GLaDOS, the AI controlling the testing, continually observes your every move.

The atmosphere is magnificent. From the clean Test Chambers, to the more messy 'backstage', it truly adds a feel of isolation to the game. Even GLaDOS' comments will make you feel somewhat nervous.

A great game, a bit too short, but nonetheless, great.


I Thought I Could...

I thought I could love this game as much as other gamers love it, but it just didn't work out. It picked pretty good in the beginning, then it went downhill towards the middle of the game. I found myself board of puzzle solving every level. After playing this game, I figured out something that I've never really realized before when I was younger; I don't like solving things. Solving things just makes me frustrated all the time, especially puzzles. It's like a chore for me, and I didn't feel like doing chores by playing a game because games are supposed to be stress free for me, but apparently not Portal.
