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.

Recommendation Summary
Portal 2 is a puzzle game with some great comedy. You play as a test subject, who uses a gun which opens 2 portals. These portals are used to solve puzzles. It builds immensely upon the original Portal with not only better graphics and a more detailed enviroment, but with amazing characters. The plot has it's twists, and is great, as it is really fleshed out. It is amazing to experience first hand. You can also play Co-op and also build your own puzzles and play other people's puzzles. All around an amazing experience, and a must play for any serious gamer.

REVIEW
Portal 2 takes everything that was done right in the first game and injects it with steroids. It boasts a longer, more diverse campaign that still manages to hold on to the humor, atmosphere, and overall quality that made the original so enjoyable. It also boasts a new cooperative mode, which brings the experience to a new level. And to top it off, with Steam Workshop integration, the possibilities for new content become limitless.

In the campaign, all of the strengths from the first game return and are fine-tuned to perfection. The puzzles are more diverse and interesting, with more advanced mechanics introduced. The atmosphere is even more fleshed out and enticing. The dialogue is even more hilarious and entertaining. And to top it all off, the game is about twice as long.

After that, there is also an incredibly well designed cooperative mode, complete with its own characters and puzzles. This adds what is effectively another whole game to the mix, which is a very welcome addition.

And to top it all off, with the Steam Workshop integration, there is endless possibilities for new puzzle rooms in both single-player and cooperative modes. Not all of it is great, of course, but some of it is arguably better than the real game. It is a gift that just keeps on giving.

With the gameplay being so intuitive and enjoyable, and the limitless possibilities of the Workshop, Portal 2 rockets to the clouds as a deity among video games. It is hands-down one of the absolute best games in existence. If you haven’t yet tried it, now is the time. There are hours of entertainment waiting for you.

Portal 2 * 10/10

Sequels often suck. NOT THIS TIME!!!!

Portal 2, as a direct sequel, doesn' change much in the base formula, so the game is still based on a more polished version of the Source Engine, is still a First Person Puzzle game but adds a lot of innovations and elements that grant this sequel the status of "Epic".

After the end of the first Portal Wwe're once again in the Aperture Science Labs, but we're in a different facility and the first thing that can be noticed is that the structures decay and some vocal messages hint that an indefinite but consistent amount of years have passed, and thanks to a Personality Core named Wheatley we try to escape the falling facility. Unfortunately We'll have to pass through the remains of GLaDos, causing her awakening and forcing us to become again Her Guinea Pig. You think this is a spoiler? FOOLS! From here the game will show it's improvement as there actually is a HUGE story plot, with plot twists and revelations that will amaze you room by room making you eager to finish the game to see the end and forgetting I've ever revealed you that (predictable) detail.

The innovations won't stop with just a (GREAT) plot, but the gameplay is incredibly improved as well. You won't have to deal with just portal related riddles, but you will face gels and funnels, where blue gel will make you bounce high, orange will accelerate your walking speed, white will allow you to spawn portal on every tainted surface and funnels are transport streams that will make you float in their direction the moment you cross them. You can't even imagine the combinations of all these elements, no to mention the events in the story.

Level design is improved far beyond the first chapter's standards. There will always be minimalistic design test chambers, but we'll have to walk beyond interspaces, factories, dismantled rooms, and immense areas that will make you wonder how big is this Aperture Science supposed to be. You will end up digging so much that you will end up in one of the very first sections of Aperture Science realized at the time of its founder Cave Johnson.

And here comes another aspect of Portal 2. They went so far with the game that hired English (obviously) Writer and actor Stephen Merchant to voice Wheatley and American (obviously) Actor J.K. Simmons to Voice the 'Murican Cave Johnson... And their accent and characterization is definitely great.

Soundtrack is a greatly appreciated news this time because even though it is subtle and thin during most of the gameplay it has some dynamics so you'll hear little flashes of melody when you're solving parts of puzzles, but most importantly there are more studied melodies especially during scenes or scripts.

The last improvement is the other section of the game... Because portal 2 has a single player campaign... AND a Cooperative campaign. We can invite a friend to play via internet and solve 6 sets of chambers precisely studied for cooperative gameplay.

+++PROs+++
  • STORY. Unbelievable, but portal 2 has a great story showing you the origins of the Aperture Science Labs, GLADos and more, and it somehow has little links to Half-Life 2 as well! Great Final, totally love it.
  • CHARACTERS. This time there are more characters, besides GLADos. All her sarcasm always makes me laugh as well as Wheatley's stupidity, and Cave Johnson's 'murican attitude.
  • GAMEPLAY. In Portal you use portals. In portal 2 you have Gels, Funnels and the hallucinating combination of these 3.
  • COOP CAMPAIGN. Great Coop campaign, perfect game to play with a friend.
  • SOUNDTRACK. Seriously this game has a very nice electronic soundtrack, this was unexpected.
---CONs---
  • LENGTH. This time the Single player campaign lasts significantly more compared to Portal and the Cooperative campaign is quite consistent as well, but I still believe they could have lasted a bit more... MOAR!!
  • SEQUEL. I've completely lost hope for a third chapter for Both Portal And Half-Life...

This review assumes you already own and have completed the first Portal, my review of which can be read here.

Game: Portal 2
Developer and publisher: Valve Software
Released: 19 April, 2011
Genre: First-Person Puzzler with Comedy
Setting: "At least 50,000 years" after Portal 1, Aperture Science Enrichment Center, Upper Michigan, U.S.A., Earth
Spoiler-free plot summary: After the events of the first Portal, you, Chell, find yourself awakening in the mysterious science facility once again. However, at least 50,000 years have passed since you were last conscious, and the facility is now in ruins. Your only hope of escaping it once and for all is to put all of your faith in one of the incompetent robots built to maintain the facility, Wheatley, who also wants to escape.

Full review: Portal 2 is a far superior game than its predecessor. Being a fully fledged game with a unique story, unique humor, new game mechanics, and new environments, Portal 2 makes Portal 1 look like a tech demo.

Portal 2 can take several hours to complete; not just because the game is longer in general, but because the tests are far more varied than Portal 1's, and require longer thought and planning.

There are several new mechanics introduced in Portal 2, such as the Thermal Discouragement Beam which replaces the High Energy Pellet seen in Portal 1, but shares the same basic concept of directing the projectile into its respective "catcher", and Mobility Gels which can either make you jump higher or run faster. When all mixed together, these can make several of the later test chambers far more difficult than the previous ones, which means having to think outside the box (sometimes almost literally). At first, these chambers might seem too hard or impossible to complete, but once you've worked out the solution, the "Aaaaah!" moment makes the struggle (and perhaps frustration) very much worth it.

Unlike Portal 1, Portal 2 doesn't have any advanced or challenge map packs; instead, Portal 2 has a challenge mode, which is a combination of the least portals created and least time taken challenges in the Portal 1 challenge map pack. Also, instead of having just six chambers to be challenged on, you have every single chamber in the main campaign to be challenged on! An online leaderboard is also included in this game mode for those who want to compete with friends.

A new game mode introduced in Portal 2 is the map maker. In a parallel universe, founder and CEO of Aperture Science, Cave Johnson, has developed a multiverse device which can send test subjects into other parallel universes, who can test, and steal, that parallel universe's test chambers. These test chambers are the player-made ones you can download and play from the Steam Workshop. With the right know-how, you can make your own test chambers and upload them onto the Workshop for others to download and play.

Another new game mode introduced is the co-op campaign. Set a few weeks after the events of the single-player campaign, two robots GLaDOS has created (you and a buddy) are tasked with solving tests which are used to train you for upcoming missions GLaDOS has planned. This game mode also includes its own online leaderboard and can also have maps made and uploaded to the Steam Workshop.

As said before, the story and humor of Portal 2 are unique. There are several twists that make you sit on the edge of your seat, and the humor, being incredibly dark, can make you laugh your ♥♥♥ off, and make you feel uneasy, or even guilty about it. There are several new environments introduced that weren't seen in Portal 1, such as the behind-the-scenes areas of the test chambers, and the ruins of 20th Century Aperture. And although there is less of a mystery aspect to Portal 2 compared to Portal 1, those with a good eye (and ears) can still find some things you'd find out-of-place, even in Aperture Science.

This game is, no doubt, one of the best games ever made. Do I recommend buying Portal 2? Of course I do! Especially if you like puzzles, or humor, or video-games, or not breathing neurotoxin. For NZD$23.99, I'd wait for a sale for when this game is $17 - $20 before buying it.

Portal 2 improves on what Valve did in Portal. This time around story is a major focus, alongside improved gameplay and new mechanics to help you solve the puzzles and make it out alive. There's also co-op, it's fun and community created test rooms to extend your playtime!

The cake is still a lie, though.

This article analyzes the tone and design of the excellent single-player campaigns in Portal and Portal 2, eventually concluding that the original Portal is the stronger title.

[. . .] I think it’s appropriate to close by reiterating that Portal 2 is a wonderful game. It’s fun and highly polished; its co-op campaign is one of the best co-op experiences ever devised; and its level editor and accompanying Steam workshop integration are practically endless sources of new content. [. . .]
