Chapter 1: The Courtesy Call

  1. Welcome back to Aperature Labs, you’ll wake up in a relaxation chamber and a computer voice will give you a brief rundown of what’s going on.
  2. Follow the directions you’re given. Use the mouse to look up and down, use W to walk forward, S and D to move left and right, etc.
  3. You’ll be directed to stare at a painting, it is located just to the left of the bed.
  4. After you look at the painting, move back to the bed and press E.
  5. You’ll wake up again and make contact with a robot named Wheatley, who will direct you to speak by pressing the Space Bar. Press the Space Bar and you’ll end up jumping instead, he’ll say that’s close enough.
  6. After this, the room will begin to move, you’re not in any danger though, so just look around and enjoy the ride.
  7. When the room comes to a stop, step out through the demolished wall, just past the bed.
  8. If you look on the ground ahead of you, you’ll see some cracked glass. Step onto it and it will give way, dropping you into a small room similar to the one at the start of the first Portal.
  9. After a brief automated message an orange portal will appear on the wall. Step through it and move to the left around the room you started in.
  10. Move toward the door with the blue person on it. The door will open automatically and you can step through.
  11. A cube will fall from a tube near the exit of this room. Pick it up using E and press E again to drop it on the big red button.
  12. With the cube on the button, the door will open and you can proceed to the next room.
  13. A second door will open and as you advance to the next room an elevator will descend from above. Get into the elevator and it will take you down to your next challenge.
  14. Exit the elevator and climb the staircase directly in front of you.
  15. Head through the door and hang a left, then drop down into the next room.
  16. If you face the toward the door you’ll see 3 red buttons: one to your left, on straight ahead and one to your right. Go press the button on the right using E. This will activate a blue portal inside a room with a cube.
  17. Now turn to your right and you’ll see an orange portal on the wall. Go through that portal.
  18. You’ll see a cube in the room you are now in. Grab it with E and take it back through the blue portal.
  19. Now drop the cube, face the door again and this time press the button to your left.
  20. Pick the cube back up and once again go through the orange portal.
  21. Now you’ll find yourself in a room with a red button. Drop the cube on that button, this opens the door. Exit through the blue portal.
  22. Face the door again and this time press the button directly in front of you, then head back through the orange portal.
  23. Make a left and get into the elevator.
  24. Get out of the elevator, head up the stairs and make a left. There’s a podium where the blue portal device should be. Move toward it.
  25. The ground will give out beneath you and you’ll fall into a swampy area. Move straight ahead and grab the portal gun at the top of the ramp.
  26. Point the Portal gun at any flat wall and press the Left Mouse Button to create a blue portal. Move through the portal and look to your right to see a ramp.
  27. Walk up the ramp and hang a right through the abandoned office, then drop down through the broken window.
  28. Stick a blue portal on the wall directly opposite the window you dropped out of. Go through the portal and hang a left.
  29. Shoot a blue portal right next to the exit door. Then turn around, go back through the orange portal and head through the exit door and into the elevator.
  30. Go up the stairs and you’ll see a cube drop into a pit in the center of the room. Shoot a blue portal at the cube and it will come out of the orange portal behind you.
  31. Drop the cube on the red button, this will open the door. Head through it and into the next room.
  32. This room has two red buttons. Throw a blue portal on any flat surface and walk through it.
  33. Now aim for the wall just behind the cube on the platform across from you and fire another portal.
  34. Walk back through the orange portal and you can grab the cube. Set the cube down on one of the red buttons.
  35. You’ll find a pit with a second cube in it across from the exit door. Fire a blue portal at the cube, if it doesn’t fall through the portal, go down and move it manually.
  36. Put another portal on any random wall and go through it to grab the cube. Then put the cube on the second button and you’ll open the exit. Go through it.
  37. In the next room, there’s an orange portal above you. Fire a blue one at the ground and jump through.
  38. You’ll land on a pane of glass. There’s a staircase in the room to the right. You don’t need to climb the stairs (although there’s an interesting view up there), just make a left out of that room and you’ll go through another door and into an elevator.
  39. Head up the steps to the next test area. There’s some debris in your way so put a portal on the ground and jump through.
  40. Look to your right and you’ll see a small red button in a podium and a large red button on the ground. Press the small red button in the podium. This will cause a cube to fall onto the platform across the pit (to the right of the tilted platform.)
  41. Walk up to the edge of the pit and fire a portal into the ground beneath the cube. The cube will pop out of an orange portal behind you.
  42. Place the cube on the red button that’s on the ground and some platforms will form a staircase up to the exit door.
  43. Once you get up to the exit door, you’ll see that you need a to put a cube on a red button to keep it open. There’s two red podium buttons past the red ground button. Shoot a blue portal onto the tilted platform jutting out over the pit.
  44. Now press the red podium button on the left. A cube will fall through your blue portal. Quickly press the red button on right to activate a panel that will stop the cube from falling into the pit.
  45. Retrieve the cube and place it on the red button. Now exit through the door and get in the elevator.
  46. After exiting the elevator, put a blue portal and jump through it.
  47. You’ll fall from an orange portal and into a room with a pit in the middle of it. Shoot a portal at the floor at the bottom of the pit and jump through.
  48. You’ll find yourself on a platform facing the exit door. To your left there’s a cube in glass case below the floor. Shoot a portal through the hole in the glass.
  49. Now jump back down to the lower level, shoot another portal at the bottom of the pit and drop the cube through it. Follow the cube through.
  50. Set the cube on the red button and go through the open door.
  51. In the next test area there’s an orange portal in the bottom of the pit directly in front of you. Shoot a blue portal at the tilted platform to your left, then jump through the orange portal in the pit.
  52. You’ll land next a cube. Grab it and place it on the raised area with the red button that is located across from you. Note: you can’t jump up there but if you raise the cube above you’re head you can put it up there.
  53. Now, face the red button, then rotate to the right until you are facing the door where you came in. Place a portal on the wall above the door as high as you can.
  54. Jump through the orange pit portal again. And put the cube on the red button and it will activate a platform.
  55. Now make a portal to the right of your last blue portal and jump through the orange portal again. Head through the exit door and into the elevator.
  56. In the next area you’ll meet Wheatley again. Follow his instructions, then pick him up when he falls off his rail. Plug him into the wall and turn around. He’ll open a secret passage; pick him up again and head down the passage.
  57. Keep moving past a turret and you’ll go through a circular door.
  58. After a brief loading screen you’ll head down another corridor and pass a passage leading to some windows on your right.
  59. Take the second passage on your right. Make your way through the rubble, past the closed disposal chute and down the staircase.
  60. When the stairs end, jump to the bottom of the staircase. Exit through the door at the bottom and then follow the catwalk until you get to the main breaker room. You’ve got a cut scene after this.
  61. Find your way through the rubble and to the orange portal gun. It’s covered with junk but GLADoS will help you out. Grab the gun.
  62. Look up and put a blue portal on one of the walls in the elevated area above your. Then use the Right Mouse Button to make an orange portal on the wall next to you and jump through it.
  63. Walk away from the starting area and hang a right. Portal your way through the wall of junk blocking you.
  64. You’ll run into an elevated area and GLADoS will set up a panel above you that you can stick a blue portal to. Do this then make an orange one on the ground level and get up there.
  65. Make a right upon exiting the portal, after a short walk you’ll see a place you can make a portal on the wall above and to your right.
  66. To your right there’s a gap and then some busted panel machines. Shoot a portal at the ground beneath the panel machines then make a corresponding portal on the wall next to you.
  67. Hop through and then head down the passageway that’s next to the pit.
  68. GLADoS will move some more rubble out of your way and then you can get into the elevator. Congratulations, you have completed Chapter 1. You, [subject's name here] must be the pride of [subject's home town here]!

Great game, got it two days early <3

@Steve

You are going to want to sail through the big circle in the name. You’ll have to launch from something slanted and you’ll need a lot of speed. I was stuck here for a half an hour or so myself ;)

I’m stuck in the dark hallway in the part immediately after the Futurama-esque tube ride.

I am stuck on ********s Puzzle number 16, I can’t figure out for the life of me how to hit the button that is guarded by three turrets. Even the Developer Commentary is unhelpful on how to get around that puzzle. If you want just email me at username then gmail dot com :D It is very perplexing and the fact that I have been playing it since Friday doesn’t help any :’( It is on the 360 version if that helps any.

Steve

On April 19, 2011 at 12:53 am

Thanks Jake, I’ve had the game for around 1 week before release for review purposes on my gaming website and couldn’t get off that stage. Now the point after where I exit lift I’m stuck, this bloody game is annoying haha!!

jakeumms

On April 19, 2011 at 12:54 pm

NP Steve. Yeah, you are definitely at the part where every puzzle is gonna be pretty hard. I’m a little bit ahead of you and it has been slow going getting there. It’s a lot of fun though and I feel like a genius when I finally figure something out!

Stuck2

On April 19, 2011 at 1:02 pm

Same here. It’s right after the puzzle with the orange portal pit where you have to launch yourself to get a cube then launch your self to get the cube to a switch and then launch yourself onto the cube platform. After going through the tube, I’m stuck in an absolutely dark area that as far asI can tell is a small dark box. Every 10 seconds or so the screen flickers with light for about .5 seconds. I do not like this part, and want to get on with the game, how do i get past this? It’s lame. X(

Up until the escape, you just need to enter the elevator to complete the levels, same as Portal 1.

Me and my brother are stuck in 1 or two level later than the last level wich is shown by the vid’s. It seem to be the last level. Will the vids be updated? We really don’t know how to solve this level. :P

Phil Hornshaw

On April 22, 2011 at 12:09 pm

Hey guys –

All the co-op videos are now live. Hope that helps.

We’ve also got new chapters coming in the single-player walkthrough really soon — like as soon as we can manage to get them ready to go. We’ll let you know here when they go live.

Parker

On April 24, 2011 at 6:21 am

How do you even smash/crush/destroy the 11 monitors? I beat the game on Thursday and I’m just trying to wrap up that last NON co-op achievement.

THANKS!!

kenny

On April 25, 2011 at 8:13 am

this game is amazing and fun. the single player ia awesome, non of the puzzle had me stumped for more then 15 minutes. and the co op you can do by yourself with another profile and controller, except for the last 2 or 3 in the last set of challenges in multiplayer. fun fun fun

Phil Hornshaw

On April 25, 2011 at 1:57 pm

@parker – we’re currently working on some achievement walkthrough videos that will outline stuff such as the monitors. That should be done pretty soon here — I’ll drop a comment to let you know when it’s completed and we get it updated. Until then, we’ve got more Achievement/Trophy guide-type stuff at http://gamefront.com/portal-2-trophies and http://gamefront.com/portal-2-achievements. Our guys are going as fast as they can trying to get this stuff up for everybody — we know how much you want it.

Kiri

On May 6, 2011 at 1:09 pm

This was so much fun! Wow, I enjoyed this game immensely!

Thank you for the helpful walkthrough :) I figured most things by myself, but it helped me with the trickier puzzles :D

Hyro

On May 21, 2011 at 9:17 am

Mahesh

On May 31, 2011 at 9:01 am

Amazing game…. i love it!! so much fun!! thnx for the walkthrough… it really squeezed my brain without the videos!!!

waiting for portal 3!!!

Svenot

On June 18, 2011 at 11:12 am

Fun game.

I have a quest, since I don’t know, what I found. Maybe nothing, but.
If you look at the video Chapter 02,07 You’ll see Wheatley after blocking the ray with the cube. A panel opens and I picked him up. I wonder if there is someting here. This is where the “Emancipation grill” is broken. And I carried him into the exit. Nothing happened, but I already had the achievement.

gamefront is a great and nice and simple site to get walkthroughs….

KimberleyJo

Husband and I are stuck in a level where it’s all one big outside square with water underneath it…with separate portal walls all the way around the squares…hard light surface is usable but we can not figure out how to get to the exit witch is slightly above the portal areas.

Alex

On July 11, 2011 at 3:17 pm

Damn!!!! I’m stuck in this huge place. Chapter 6 right after the part wher you use portals to put the blue goo drops on the wall! I’ve tried everything, just keep failing or falling in the water, HELP!!!???

Christian

On July 21, 2011 at 7:53 am

I am stuck at the final of chapter 7, when the hatch goes open and a kind of elevator is going down:
116:A lift type contraption will lower itself out of the hatch in the ceiling. Get to it and get inside.
I am trapped in the control room and I can’t jump over the railing !!!!

Daz

On July 25, 2011 at 1:40 pm

You don’t need to jump over the railings. Jump through the window, or rather, where the window used to be. Took me almost 15 minutes to figure that out. XD

Baz

On October 7, 2011 at 1:16 pm

Got this yesterday and now stuck in the neurotoxin control room.
Thought I needed to direct the laser as per 33/34 above but couldn’t create a portal in the moving panels?
Thought I was missing something but after reading this I’m thinking bug? Any suggestions??

Baz

On October 8, 2011 at 3:31 pm

Ok, got passed the neurotoxin room. You really do need to create the blue portal first outside, otherwise you appear to need to restart the level. Restarting the game/reloading a saved level didn’t help – rerunning the level from the start worked fine.

KEITH

On October 29, 2011 at 6:43 pm

HOW DO YOU DELETE A SAVE GAME?

THE DELETE WILL NOT WORK.

THANK YOU KEITH

Toph

On December 25, 2011 at 11:21 pm

Hey! thankyou so much for the walkthrough, its been a great help, although im stuck at chapter 7, #105, no matter how hard I try, I cant manage to hit the surface behind that grate with a portal! any ideas?

Kimi

On August 17, 2012 at 3:53 pm

I’m having -major- issues with the Crab cubes.. they keep falling through the funnels for me. either their wight has been incressed or it’s an issue of “state” cuz they drop each time they shift from legs out/in. I can’t get the Master Funnel achevement and I think porting in a normal cube to complete chamber 3 as the crab cube kept falling through the funnel on the other side, may have glitched the game so it doesn’t think I beat it even though I have. my friend said spawning a cube shouldn’t disqualify achievements or progression cuz the normal cubes work fine.. crab cubes.. not so much. I spent an hour trying to do chamber 3 and hour when it should taken only moments. I made sure to place the funnle in the right spot but no. crab cube would either get pushed away to the side of the funnel or go in then drop through it only few seconds latter.. any ideas?

pookie

On September 29, 2012 at 11:34 am

one of your videos is broken. the 5th one down to be more specific ;)
