Return to Aperture for further testing. Our Portal 2 Walkthrough provides a walkthrough for story mode, tips for co-op, and unlockables.

Portal 2 Walkthrough

The Courtesy Call

This first chapter will introduce you to the basic controls of the game and return you to the beginning areas of the original Portal. Listen to the Announcer and Wheatley's instructions to get through the first movement tutorial. Once gaining full control, you will still be missing a portal gun; however the system will automatically form portals for you. Move through the orange portal on your left and then right through the door to the next passage. Here, grab the cub that drops and place it on the red pad, which will open the door to the next area. Take the elevator down to the first level of testing.

Floor 1

Because you still lack a portal gun, you will need to hit switches to turn on blue portals. There will also be an orange portal placed behind you. First hit the switch on the right and enter the portal to grab the cube. Return to the center and hit the left button, allowing access to the red pad. Enter the orange portal and leave the cube on the pad to unlock the door. Return back into the center and press the middle button to place the last blue portal. Take the orange portal again to reach the exit.

Floor 2

Start by moving forward to the portal gun stand. The ground will break below you, causing you to fall into the waters below. Move forward up the short stair case to gain the blue portal gun. Fire a blur portal and exit through the generated orange portal. Move right and head down the corridors until located the next automated orange portal. Fire a blue portal and exit through the orange one. Turn to the left and fire another blue portal near the exit. Backtrack through the orange portal and arrive at the exit.

Floor 3

Head down into the pit and fire a blue portal. Grab the cube that falls below and carry it through the portal. Drop off the cube on the red pad to unlock the door to the next area. In this room, fire a portal down the pit to the right. Grab the cube from there and enter the portal. Drop the cube down to the main area and fire a new portal to the second cube on the opposite platform. Head backwards and pick up the second cube through the portals and drop down. Place both cubes down to unlock the door ahead. In this next room place another blue portal to move through the orange portal on the roof. Move ahead and reach the elevator to the next floor.

Floor 4

Place a blue portal on the floor and exit from the already placed orange portal. Press the switch on the right and form a portal below the cube that drops. Take the cube and place it on the red pad to the right. This will construct a set of stairs on the left. Climb up these steps and shoot a portal on the diagonal platform. Hit the switch on the left to release the cube and the switch on the right to prevent it from entering the water. Grab this second cube and place it on the red platform at the top of the stairs. Enter the now unlocked door to reach the next floor.

Floor 5

On this floor fire a blue portal to exit out the orange portal above. Look down the long pit and fire another blue portal. Drop down and use the speed of the fall to propel you to the other side. Look down the hole to the left to locate a cube. Fire a portal here to release the cube back to the pit area. Hop back down and replace the blue portal at the bottom of the pit. Grab the cube and once again leap down below. Place the cube on the red pad on the right and enter the next room.

You'll need to take a dive to stay on top

For this room place a blue portal on the tilted platform on the left. Jump down the pit below to enter the orange portal and be thrown to the cube above. From where you land, place a blue portal on the left side of the wall in front of you. Grab the box and drop down the orange portal. Place the cube on the red button to raise a platform leading to the exit. Drop back down the orange portal again to reach the elevator to the next floor.

Floor 6

Move forward and place a portal behind Wheatley. Enter the orange portal to get to the other side. Wait for Wheatley to blab and drop down to your level. Pick up the personality sphere and insert him into the node on the wall. Look away to give him some privacy, and return when he says he's ready. Pick Wheatley up and head down the new passage.

Floor 7

Head forward to the other end of the room and drop down the broken stairs. Head down the underground pad and place Wheatley in the main breaker room. After a short scene you'll find yourself in the incinerator room. Move forward and grab the dual blue-orange portal gun. Place an orange portal above and a blue one to the left to move beyond the barrier ahead. Set down another set of portals to get through the next barrier. In this next hallway place one portal on the tilted wall and the second in front of you. Enter through the portals and move to the right. Shoot another blue portal above and another orange on the left wall to reach the floor above. Fire another orange portal into the next room. Move down the path on the left to reach the floor's elevator, ending the chapter.

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.

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 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.

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.
