Portal 2 is a great game. The levels were hard enough that I couldn't figure them out straight away, but could still noticed the solution after 5-10 minutes. Games like Modern Warfare 3 couldn't hold a candle.

Such a great game, the level design shows Valve's creativity. I wish companies like Infinity Ward would take a few hints while making mw3 and its levels. Modern Warfare 3 could use Valve's "touch", just look how great this and Team Fortress 2 is.

I only checked this to see how many chapters were in the game :P

Brilliant game. Wish I had bought the first one before I played this one, but it's so good it doesn't matter. Excellent voice acting and brilliant puzzles - keep it up Valve!

@ icepop4who: If it's so easy and you don't need a guide, what are you doing here? Hmmmm.... Kind of strikes me as an 'I'm better than you guys statement to me'. The truth seems to be, I got stuck somewhere and needed a little nudge in the right direction.

I think this is a great game. but sometime u have to spend an hour on a single floor in the later levels because it gets a bit hard.but still a very good game

I just dont understand the point of listing the trophies if you are not showing how to get them step by step? I mean its a guide right?

lol this is the easiest puzzle game ever. As long as you're not ADD or something, you don't need a guide. Just take your time with it.

Who writes this stuff? It's "levers", not "leavers"! Portal is the bomb, tho' (GLaDOS made me say that)

Pretty good guide, but for god's sake please learn the difference in "passed" and "past."

I love this phreaking game. Right when I thought it was going to end, it keeps on going! I thought it was more of Portal 1, then it goes nuts! The levels are organic, believable and atmospheric. Look out for my review. Incredible game.

What kind of idiot would actually use a Portal walkthrough? Solving puzzles is literally the only thing to do in this game. It's like paying money to have to read and follow a guide.

Without photos can be as frustrating to understand as some parts of the game. Try the youtube hints if you are really stuck.

If you liked the first Portal, you will love this one.. it has a good story and about 7hours of pure puzzel thinking. Some stages where way to easy and some took me a while to figure out. I also loved the twists of the game. To all of you that have played the game i only say "Im in space!" It was great fun.. Thinking of buying the game for ps3 aswell..

@Maxxramman ... *gag* there are three words I bet no one on this planet EVER expected to hear in a sentence: "amazing" and "will ferrell." WOW! I'm intrigued by how stupid parts of this game make me feel at times. To help with that I went and bought the first one. STILL have no idea how or why i'm blasting holes in walls just to be tested by this badly auto-tuned android! HOPEFULLY there will be sometime soon in the game where the greater meaning is revealed (I'd settle for the point ; ) Its also a little strange that the character you are supposedly playing as is a female. Hmmm maybe this is how a female feels if she chooses to play a FPS, i.e. CoD. Interesting.

@JeyNyce Thx. Had a look at some gameplay and decided 2 buy it.

@Kos1c & @XsickGamerX10 - It's more than just a puzzle game. It has a great story behind it and it ties itself with the Half Life Universe. I think it's a great game. It's better to have played the first one before playing the second.

@XsickGamerX10 I didn't know much about this game, and i got it yesterday. The game is a huge puzzle game, it's great fun, just sadly it's not as long. I've already completed it, took about 4-6 hours to do. But still one of those titles worth checking out. An easy 9/10 for me.

There has been a lot of hype about this game so ive looked at some trailers and I just cant see what all the fuss is about and it looks quite boring. So i have preordered LA NOIRE. But please if u have the game tell me what is so good about it

@djball They are hardly holding your hand. It has happened to me that I had no clue where to go due to an obscure portal-friendly surface.

@bigkahunabuger portal 2 does not have a singleplayer section...only a game mode you can play by yourself...that shows gamestpot doesn't have a clue about games.

The achievement for the propulsion gel is "Stranger than Friction", not stranger than fiction, like the amazing movie with will Ferrell.

I would really discourage the use of a walkthrough for Portal 2. Its charm comes (at least partly) from the satisfaction of solving the puzzles, and being told what to do diminishes your experience of the game. I guess using one section if you're really, REALLY, stuck would be okay, but please go back and be sure that you need the help before seeking help.

Nobody needs a walkthrough for portal 2...

I have Portal 2 and in my opionion it is to easy, I completed it in 7 Hours. The puzzles are good enought but there is only 1 way to solve a puzzle and it is easy to find the solution. The Story is realy great it has some realy good twists in it.
