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.

  • 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.

I love this game so much. Like, I could play this game every day for the rest of my life because of how much it offers. I would play Co-op with anyone. I've beat this game 5 times and I've speedrunned it. If I can't stress how much I love this game, I want to state that I really love this game.

Ughh until I do a proper review, WHICH I WILL. I can only say that this is truly a masterpeice, and I have no complain about this game. This is in my opinion the example of a perfect game.

I've gifted this game nearly 10 times now. I've made it my tradition to gift Portal 2 to any friend I introduce to steam to, and let me tell you know, each one of them ends up being an loving portal fan.

Buy this game, no questions. It's meta critic of 96 and the most positively review steam game for a reason!

Just get it. Thats all I have to say. It has a great story line and some great mods that are out now and are being made. The game could be played over and over and challenge your friends with challenge mode recording your time and portals for indivual levels. There are some great easter eggs and funny moments. You should play Portal:Staying alive before you play this game, but is not required. Some of the story makes no sense because you havent played the first game. This game has community levels which makes it fun after you have played the whole game over and over. I would defiently get this game in a bundle but Ive got both Portal and Portal 2 on xbox360. It is currently $8.74 for a bundle which is totally worth it.

Valve made so epic games i can say that. But, come on guys it is 2016. We need another games. Its time to release new games half-life 3, portal 3, left 4 dead 3 etc.
So we need third games. Am i wrong guys?

Portal 2 is a decent first-person puzzle-platform game, developed and published by Valve Corporation, and honestly this game is really... VERY DECENT, and the story is really awesome, but i won't talk about it in my review, i want to let you discover it if you buy it ;)

About the game engine: The game is running on the Source Engine, yes the same engine of Half-Life 2, Left 4 Dead 2, and Counter-Strike: Global Offensive, But Portal 2 run much better then CSGO, so any pc basically can run it without problem.

Positive Thing about this game
- Nice Graphics
- Like i said above the game can run on any pc basically
- The Story is very decent, but you need to use your brain in it since it's a puzzle-platform
- Possibility to play in Coop with one of your friends :)
- We have a real story mode, instead of the first Portal which the story mode can be beat in 2 hours, When portal 2 is 7 hours long, but it's worth it

Bad things about this game

- Nothing i didn't encountered any bugs or found negative thing to say here

To finish

This game is a must have, like i said, the story mode is really awesome, and brain intensive LOL,
So you need a puzzle-platform game ?! GO AHEAD with Portal 2 ;)

Fell off course 3 platform in co-op hub.

GLaDOS immediately booms, "How did you fail? It's not even a test!"

But I really couldn't figure out a way to get down. ._.

Anyways 10/10 great game that still plays well and looks good in 2016, with wonderful dialogue. A must have for your library.
For achievement hunters, I took about 26.2 hrs to get everything, but according to GLaDOS I'm not that bright and I've seen other people take less time.

I was negatively biased towards this game before I played it. Wasn't even sure about buying. I dunno, the whole portal gun and PORTALS thing seemed weird to me even though I like science fiction.

BOY WAS I WRONG. The jokes and voice acting in this game is phenomenal. Just amazing. It's not cheesy (ok it's sometimes cheesy). And different story characters have all their own sense of humour. Those different characters do really have different personalities. And the level design; it's just rad.

BTW I never played the first Portal game. One of these days, I'm planning to if I can spare the time. I would never have played it if I hadn't played the sequel. So it's that amazing.

What are you doing in this game? It's actually the sequel to the first Portal game like I said. But basically, you are trapped inside a training facility. A training for puzzle solving. The thing is, the facility is offline, and nothing is working. It's derelict. And the show runner is nowhere to be seen. Then you are woken up in the middle of all this, by your only friend. Together you try leaving it while solving puzzles that concern teleportation and portals. Then things happen. And everything turns weird.

Like I said, there is a lot more to it than this, but this is all one can reveal without spoiling it. This game would be a solid 10/10 which I wouldn't rate for the 90% of other games in my library.

+ There is online CO-OP and a mod for local CO-OP
+ Challenge mode
+ Download community-made levels
+ Hilarious voice acting and jokes
+ Seriously intriguing story
+ I never thought robots' personalities would be so awesome. oh wait
+ Time travel
+ Ripping your hair off during puzzles
+ Resist temptation for walkthrough videos
+ Co op is amazing (laughed a bit too much)
+ Single player is amazing
+ Teleportation makes sense and no sense at all at the same time
+ Nice music
+ Nice graphics

10/10 would love Glados to the death again
