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.

This game is something special. It is the kind of game that you will really enjoy (I really mean feel stupid and rage) from its level design and appropriet dificulty. The story is engaging and will make you actually care about the characters. I do recomend to play the original because some other players believe that Protal (1) was the better game because Portal was a puzzel game with a story wrapped around it. Portal 2 is the opposite, a story with a puzzel game wrapped around it.

I highly recomend that you play this game, but make sure that you check out the first Portal.

PorTaL 2 is the sequel to one of the best games of all time. And... it is pretty much better in every single way possible.

Pros:

The best voice acting you will ever hear in a video game
Great puzzles (good balance between easy and impossible)
Really interesting story
Really funny
SPACE!
Portals are fun to mess around with
just about everything

Cons:

It ends.


Portal 2 is a perfect game, and my favorite game of all time.

Great game! Play it with a friend, or yourself. It has very difficult levels, but if you are playing co-op it is always fun to figure things out with friends. next on my list is SinglePlayer!

This is my first review so please don't judge me if I fail to follow the form.
Few years ago my brother and I played this game. When he saw it on winter holiday sale he "made me" buy it for both of us.
I finished single player first and I just love quotes, both Wheatley's and GladOS's. Single player felt longer then first game's and that sudden fall and change of surrounding is great. Cherry on cake is credit song which I only saw on Portal games and make these games so special.
I also like fun that doing these achievements brings, from throwing yourself into pit to breaking screens that results with some funny Wheatley's quotes.

I think many people will agree with me when I say that co op is equaly good but even more fun the single player.
That is the element of game that I spent most of my in-game time on. Playing standard co op levels seperated into 5 groups of courses (not counting bonus courses) is great way to first learn game basics (in case you didn't play single player) but also to realize how good is your partner (how good reflexes he/she has, how much time is he/she willing to spend thinking, is he/she too stubborn to be played with, can you two understand eachother and how good host he/she is). I can say I played with at least 10 different partners I met online and finding few that I really enjoy playing with was not easy task.

I also love the fact it has option to design your own test chamber and publish it on Steam Workshop pretty easily. Thanks to that you can, while in game, browse for the test chamber that is on your level (to be honest probably everyone after playing standard co op or/and single player for few times gets better on understanding game rules so he/she can solve harder tests more easily), subscribe and play it. There are whole collections of tests, some even with custom graphics and voices used to tell you original story through testing. You can choose from racing test to very complex one that require thinking.

Playing this game you can very easily catch yourself asking how did time pass by so quickly. One of my co op partners and I spent over and hour playing just one test, but I don't regret a second because it was so much fun :).

I am going to finish this with conclusion that this game connects different people which all have one thing in common- they are ready to do some testing :)

I really hope I didn't fail form and this review helped someone decide to buy this game and be satisfied with it like I am.

If you want to make maps download the Portal 2 Authoring Tools NOT the ingame one. You can accomplish much more in the Portal 2 Authoring Tools if you want to make a chamber.

Not an actual review but saying this so that no more -annoyingly- bad maps keep happening from the Portal 2 editor.

You can make things such as custom decals, you can add props, you can add computers, YOU CAN ADD BALLBOT and you also get access to every item in portal 2. That includes wheatley core, as well.

Portal 2 is a masterpiece, a work of art that you will love for its ingenious story pop-culture, references to logical puzzles and co-op multiplayer. Definitely a candidate for game of the year.

According to reviews, this is the best game ever, next to Euro Truck Simulator 2.
