Portal took the gaming world by storm back in 2007, and it's still highly popular seven years later. And for those of you playing at home, that's one Master Sword pull. This game was never supposed to be as big as it is, it was just a small project. But it's tremendous popularity got the game a sequel, and a bunch of merchandise. But, let's take a closer look at this game shall we?

Graphics: 73/100
The graphics for this game aren't that big. It's a Half-Life 2 mod, and it has the same materials mainly. But the most you'll be seeing are white walls and floors, and later, grey walls and floors. The deadly pools of...Neurotoxin I think? Well, the deadly pools look pretty impressive too.

Music: 85/100
This is a very quiet game, there isn't really any background music for the most part. But there IS a radio you can take with you the entire game, and it plays a chipper little tune. So there's that. Also, the voice acting, there are only 2 things that talk in this game. And neither of them are you . There is the "friendly" little turrets, who shoot at you. They will say things like "There you are", "I don't hate you", "Where are you?", and a few other things. They have cute little voices, but they will shoot enough bullets at you to supply a small army. And then there's GLaDOS. The snarky, passive-aggressive, psychotic, and evil A.I running the facility. She has a pretty heavily filtered, monotonous voice. But, she's a robot, so you can't be TOO mad at her for that. But the bulk of this score comes from the credits. Instead of something boring you'd skip right through, this plays a song. Still Alive, one of the most passive-aggressive songs ever written. And it's awesome!

Gameplay: 90/100
The gameplay is pretty cool. It's one of the few First Person Puzzle games out there. Well, you solve your problems with a gun, only this time you're not murdering someone! Instead you're shooting the walls. Two shots for both ends of the portal. You go through one, and you come out the other. It's a simple concept, but the levels can be pretty tricky.

There isn't that much depth to this game. This game is 19 levels long. (The nineteenth being a pretty long Marathon Level) You have no choice but to go through Test Chambers, built, and led by GLaDOS.

The difficulty isn't too bad. Like most games, it progressively gets harder. The hardest would be the Challenge Mode levels, which put an interesting spin on a few levels. Such as all the turrets being in protective cages, not being allowed to touch the floor, or only using 4 portals.

The controls are pretty smooth. As the valve, and first person PC gaming standard, it uses the easy WASD controls. Your left mouse button fires the orange end of your portal, and the right fires the blue. And E picks things up. You'll be using all buttons very often.

Battle...If you can call it that. It's more like knocking the turrets over. The turrets have unlimited bullets. And they shoot you as long as you're in front of them. But to defeat them you simply need to go behind them, pick them up, and drop them. Or, get something to knock into them, or make them fall with your portals. You regenerate health, but if you take too many bullets at once, you die. But there aren't any lives, so you don't need to worry about a Game Over. The final boss battle is fought completely with portals too. So throughout the entire game you need to think creatively.

The story? You mean to tell me this short game about putting cubes on buttons and shooting the wall has a story? Why yes, Karla the Complainer, this game does have a story. Lots of it was unknown until Valve released a comic alongside Portal 2. But here it is, with as little spoilers as possible. Aperture Science is a competitor with the Black Mesa Research Facility. This time, they were racing for portal technology. And while Black Mesa's attempt led to Half-Life, Apreture seems to have nailed it. But at the same time they were working on brain uploading, and artificial intelligence. They built GLaDOS (Generic Life and Disc Operating System) But unfortunately the robot was evil, and every time they plugged it in, it would flood the research facility in neurotoxin. There was only one survivor, Doug Rattman. He always knew that GLaDOS was evil, but he was also a paranoid schizophrenic, so nobody believed him. But he cooked up a plan to stop her. He sent Chell to the top of the Test Subject list, with her stubbornness and determination, there was a chance that robot could be shut down for good! Some say that Rattman still hides in the Test Chambers...

Pros and Cons: 80/20
This is a pretty good game. It's a little dark in humor sometimes. But it has a great story, some hilarious one-liners, and unique, solid, gameplay. The only truly major downside is the game's short length. The sequel is a good approximately five times longer. But the game is totally worth a playthrough. You won't be sorry to play it.

This is good. Of all the Steam reviews you have done so far, I feel that this one is the best. I love the detail, and it's length. Keep up the good work and you will be awesome in no time.
