Perpetual Testing Initiative




The "Perpetual Testing Initiative" has just been expanded to allow users to design co-op puzzles in Portal 2! This update also introduces a “Quick Play” feature, giving you quick access to the top-rated maps in various categories.

About the 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.

Portal was sort of a little experiment of a huge company. That’s why success of the first part of the Portal was a surprise even for the VALVE. Therefore seriously question arose about the Portal 2. And what we got? Let's see.

 STILL ALIVE?

  The game begins with the fact that Chell along with her new partner, personality module Wheatley, is trying to escape from an abandoned Aperture Science laboratory. Throughout the game, the plot makes a interesting twists. Individual deserves compliments perfect finale, after which there remain only a warm feeling. In Portal 2 no epic stories, huge explosions, incredible action, or the salvation of humanity. Instead, there is a charismatic characters, intelligent humor and interesting puzzles.

 ONE IS GOOD, BUT TWO IS BETTER

  One of the achievements of the new Portal has been the emergence of the cooperative. Co-op story is a continuation of the plot of the single player. At first I thought that the only difference of the cooperative is the presence of two players with portal-guns, instead of one. In fact, the cooperative has unique ideas. Many puzzles solving quite differently. I advise you not to play cooperative with a random person (there is that possibility), and play it with a good friend.

 ENDLESS TESTS

  In game was added a level editor, so anyone can create their own test chambers or try to play the levels of other players. To be honest, most of the player-created levels are too simple or ridiculous. But there is sufficient interesting maps (and some of them really hard). In no case do not miss the community maps.

 Multiplayer:
  Online: Θ Θ Θ Θ Θ Θ Θ Θ Θ Θ
  Co-op: ☺☺☺☺☺☺☺☺☺O
 Storyline: ☺☺☺☺☺☺☺☺☺O
 Graphics: ☺☺☺☺☺☺☺☺☺O
 Gameplay: ☺☺☺☺☺☺☺☺☺☺

 

 Complexity of the achievements: All achievements can be easily earned (if you have good friend for the co-op) in the one-two walkthrough.

    VALVE made another good
  game. With good intelligent humor,
  charismatic characters and unusual
  interesting gameplay.

                            As expected, nine out of ten [9/10].

Portal 2 is an UNMATCHABLE game


Pros:
+ Vaious game elements(tools)
+ Exciting and intriguing story
+ Proper difficulty
+ Long content
+ Surpport steam workshop
+

Cons:
- What else do you want ?!
-

Though it is redundant to write a review for such a famous game, I just cannot surppress my passion for it.

Portal2, similar to its precedent, is a first-person physics-based puzzle game. Player need to solve different puzzles in chambers, by using a special gun and interacting with various game elements. Compared with Portal1, Portal2's world is bigger, story thicker, and the character development more surprising. The jokes and sarcasms from two robots, GLaDOS and Wheatley, make this interesting game even more funny (:'(though sometimes those sarcasms are too brutal). Besides, what surprised me is that the single-player mode is only the game's first half, and the multi-players mode provides players a even more interesting and challenging experience. Also, surpporting Steam Workshop greatly increases Portal2's re-playability.

But the advantages above are still insufficient to make Portal2 a masterpeice. As a puzzle game, what disdinguishs Portal2 from others is its ABILITY TO COMBINE. Firstly, there is a common drawback among other puzzle games: fragmented story. It is very hard to write a continuous story when puzzles' types are the same, for the repetition greatly weakens the reality. To solve it, most puzzle game choose to write a fragmented but poetic story(ie. Braid, the Bridge, etc.). Therefore, players need to create the whole story by themselves from bits and pieces. I think this method is every wise, but that how Portal solves it is phenomenal. Portal2 not only has a continuous story, but also connects every puzzle logically. For example, when "I" was handling with those discarded old chambers on the bottom of the facility, players will realize that the "puzzles" has been extended out of chambers. "I" need to solve puzzles not only to beat chambers, but also to reach the next chamber. Thus, Portal2 perfectly combines the puzzles with story, and reality with repetition. Secondly, Portal2 combines an element of action with puzzles. During the game, player will experience escape, exploration and even a Boss battle! Although its topic is puzzles-solving, players can still enjoy an exciting adventure. Thus, due to its continunous story and action element, actually I prefer classifying Portal2 as a action-adventure game to a puzzle game.

Finally, I want to say somehing about game elements. My favorite one is white Conversion Gel, which allows surfaces to accept portals. The reason is that it hides the solution to puzzles, and creates countless probabilities. In most case, solutions are so sensible that players can understand them immediately (if you find small white areas exist somewhere strange and isolated, you definitely will find them useful). But the white gel makes it impossible. Therefore, this stuff converts "to use existed conditions" to "to create conditions". Besides, it gives us a big hint of how to defeat Wheatley. Do you remember how white gel was invented? LOL

In conclusion, Portal2 is a unmatchable game which will be remembered forever. It is concise, it is intriguing, it is classic.
