About This Game

Portal 2 draws from the award-winning formula of innovative gameplay, story, and music that earned the original Portal over 70 industry accolades and created a cult following.

The single-player portion of Portal 2 introduces a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers. Players will explore never-before-seen areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion who guided them through the original game.

The game’s two-player cooperative mode features its own entirely separate campaign with a unique story, test chambers, and two new player characters. This new mode forces players to reconsider everything they thought they knew about portals. Success will require them to not just act cooperatively, but to think cooperatively.

Product Features
  • Extensive single player: Featuring next generation gameplay and a wildly-engrossing story.
  • Complete two-person co-op: Multiplayer game featuring its own dedicated story, characters, and gameplay.
  • Advanced physics: Allows for the creation of a whole new range of interesting challenges, producing a much larger but not harder game.
  • Original music.
  • Massive sequel: The original Portal was named 2007's Game of the Year by over 30 publications worldwide.
  • Editing Tools: Portal 2 editing tools will be included.

What's to say? Creating a sequel to a classic is no simple task. But somehow, Valve did it. They improved Portal every conceiveable way.

If you liked Portal 1, you'll LOVE Portal 2.

Portal 2 is the follow on to the extremely successful first person original. The game retains all of the game play elements from Portal 1 and adds lots of new features such as bridges made from light beams, and splashing paint gel which accelerate your speed or make you jump higher.

In the single player campaign, you play as Chell. As with the original Portal, your character can take a small amount of damage before they die, thankfully like the original you don't take fall damage still. The aim of the story mode is to explorer the Aperture Science Lab, which is filled of complex puzzles that have a clear exit point, but there are also other parts of the game which are not so clear leaving the objects less clear.

The tutorial at the start of the game explains all of the game play elements very well and gets you well prepared for the on coming puzzles; and whenever there is a new element introduced, the game does a very good job of making you aware what it does without shoving a tutorial screen in your face every time.

Portal 2 is powered by the Source engine, like all of Valve's more recent releases (Half Life 2, Left 4 Dead, TF2), and it looks stunning. You will find it hard nowadays to find a game that looks as well polished as Portal 2, all of the colours, textures and visual effects are done perfectly.

Story-wise is the feature in Portal 1 that I thought it fell down on, however in Portal 2 they knocked it out of the park. It follows on from the story line set in the original and goes beyond the level of detail and complexity that you would expect. I needed to find out how it ended once I started playing, and the ending is just beautifully crafted.

The difficulty is like most puzzle games, if you are good at them, it will just come naturally. It definitely has a better difficulty curve when compared to the original, but even still at times I had to revert to a walkthrough to pass through some puzzles (shame on me eh?) but there is nothing here that can't be solved if you sit and think for a couple of minutes each time.

The single player story mode took me about seven hours to complete, this to me is a perfect length for a game of this type, the game ends at a high point and I was 100% satisfied with the outcome. There is also a co-op campaign included which will also add a good number of hours. On top of both of these, we also have Steam Workshop support, meaning endless hours of mods and different chambers to try and master. I have yet to try any out yet but some of the maps and rooms I have seen on the workshop page just look amazing. I wouldn't be surprised to see people being able to get fifty plus hours in this game.

In conclusion, Portal 2 is a must play for any gamer out there. It is an absolute classic that should certainly be in your library. It goes on Sale every few months so most people will already have it, but you need to play it.

One of the best games in my library? Certainly.
One of the best games available on Steam? Most definitely.

This game requires you to think out-of-the-box, and will have you solving puzzles constantly.
The dark humour in this game is hilarious aswell, and that only adds to the great experience.
The singleplayer is great, but solving puzzles with a friend is possibly even greater, and allows for much more complex contraptions. Even after you finish the story, you can download heaps of custom-made community maps, which allows for tons of extra hours. I highly recommend it ;)
