Chapter 6: The Fall

  1. After you finish falling, you’ll find yourself in a pit strewn with debris. Follow the little stream and then take a right.
  2. You’ll walk across two fallen beams and into a large pipe. Take a right when you get out of the pipe and you’ll see a chain link fence. On the other side of the fence, to the left, is a wall you can put a blue portal on.
  3. Put an orange portal on the wall behind you and jump through.
  4. When you get to the other side, look up and to your left. There’s a piece of ceiling that you can put a blue portal on. Put an orange portal on the wall and get up there.
  5. Face the red pipe. Now make a 90 degree turn to your right and you’ll find a gap in the wall. Go through the gap and take a left.
  6. When you hit the dead end, you’ll see a fence on your right.
  7. Look through the fence and on the left you’ll see a white surface you can portal to.
  8. Jump off the broken catwalk and follow the grey path straight ahead.
  9. When the path gets blocked by debris, hang a left and you’ll start heading uphill. There will be a wall that says “Condemned Test Area.”
  10. While facing the wall, look up and to your left. There’s a fire escape on the side of the building and at the landing there’s a flat surface you can hit with a portal. Warp up there.
  11. Walk down the catwalk and look down to ground level. You’ll see a flat beige section of wall on the other side of the wall. Hit it with a portal and get down there.
  12. When you come out of the portal, hang a right and you’ll see signs that say “Do not enter” and “Keep out.” Walk past these signs.
  13. You’ll find a grey pipe you can jump down to. Follow the pipe.
  14. When you come to a closed gate look to your left. There will be a lever; pull it. The gate will open and you can hop down.
  15. Directly ahead of you is a big circular vault door. Look up and to the left. There’s a control room you can portal your way into.
  16. Once inside, push the red button that says “hatch override.” Now portal over to the control room directly across from the one you are in. There’s another button that you need to push.
  17. When that’s done, you can enter the hatch. Behind the big circular door was a much smaller grey door. Go inside.
  18. After going through a second door, take a left. Walk across the catwalk and head up the steps.
  19. Once up the steps, find the vault door that’s cluttered with rocks. It’s open a crack and you can portal your way in there.
  20. Now walk to the door with two windows in it and look to your left. There’s a lever. Pull it and the door will open.
  21. Look up at the catwalk that says “Main Lift.” To the right of that is an angled piece of pillar.
  22. Look way above the angled piece of pillar. There’s some metal beams you can portal your way onto.
  23. Once up there, look down. You’ll be able to hit the angled part of the pillar with an orange portal. On the ground just ahead of that is a flat place you can hit with a blue portal. Hit it and jump through the blue portal. You may have to walk around the beams to find a good spot to jump from.
  24. You’ll come shooting out of the orange portal, through the Aperture Science sign and land next to a door that will open automatically for you. Go through it.
  25. Hang a right, go through the reception hall and another sliding door. You’ll find a lift on the ground level. Get in and press the red button to start moving up.
  26. When the lift stops, get off and take a left and another left. In the distance you’ll see couple of doors set in a wall that you can hit with a portal. Zoom in and you’ll see that just above the door, the concrete is angled up.
  27. You want to stick a blue portal on the part that’s angled up, just above the blue door on the left.
  28. Now walk around the lift, start heading down the steps but look towards the interior. After a couple flights you’ll see a way to get into the center of the elevator shaft.
  29. At the very bottom of the elevator shaft is a floor that you can put a portal on. Put an orange one on it and jump down the shaft.
  30. You’ll come shooting out of the blue portal and land on a catwalk.
  31. Go through the door.
  32. Take a left, go into the control room and find the lever that says “Gel Pressure Control.” Pull the lever.
  33. Find the wall with the blue and white “Alpha” painted on it and look up. There’s a doorway with a catwalk leading out from it.
  34. Portal your way up there and step out onto the catwalk.
  35. Hang a right, climb down the pipe and pass through the emancipation grid into the elevator.
  36. Make a left at the “You Are Here” sign then make a right and head through another emancipation grid.
  37. You’ll find a pit filled with blue goo. Jump into the pit and you’ll find the goo makes you bounce.
  38. Bounce your way to the other side.
  39. Now make a left turn and look up. To your left you’ll see a platform you can portal up to. Get up there.
  40. Now turn towards the blue pit. Across from you, you’ll see a red podium button. You need to use the blue goo to bounce over there and press it.
  41. A cube will fall out of a cube chute. Take it back to the platform with the red button and set it on the button.
  42. Now bounce back to the exit landing and exit the test chamber.
  43. The bridge to the next test chamber has been destroyed. Head up the catwalk and look up and to your right. There’s a spot you can hit with a portal.
  44. To your left, at the edge of the catwalk on the left-hand side, you’ll see another wall you can hit with a portal. Do it and jump through.
  45. Hang a left out of the portal and when you get to the edge of the destroyed catwalk, jump down onto the steps. Then walk through the emancipation grid.
  46. Look to your right and you’ll see a panel moving back and forth on a track. If you look above the panel when it has reaches the wall on the left, you’ll see a piece of ceiling you can hit with a blue portal.
  47. Once you’ve hit it, use the blue goo on the ground to bounce up to the next level.
  48. Put an orange portal on the wall, then look through it and wait for the panel to show up. When it does, jump through.
  49. As the panel moves, you’ll see a room with a cube in it on your left. Grab the cube.
  50. If your standing in the room with the cube and you look to your left, you’ll see a raised area with a red button.
  51. Stick a blue portal on the wall by the red button.
  52. Now take the cube for a bounce on the blue goo and put an orange portal on the wall.
  53. Hop through the portal and put the cube on the button.
  54. Now follow the orange line leading away from the button. You’ll find that there’s now a panel on the wall that you can put a blue portal on. Do it.
  55. Put an orange portal on the wall behind you. Jump through, bounce on the goo and you’ll land on a platform with an emancipation grid and a button behind it.
  56. Step through the emancipation grid.
  57. There’s blue goo on either wall and a pit in the center. If you jump into the blue goo, you’ll find you can bounce back and forth and move forward. Do this to get to the other side.
  58. Grab the cube, bounce off the blue goo on the ground and set the cube on the button.
  59. Step back through the emancipation grid and you’ll find that a new panel has appeared. To find it, look to your left and then look up. It will have a number 2 next to it. Put a blue portal on it.
  60. Now bounce on the blue goo, stick an orange portal to the wall and jump through.
  61. You’ll fall into the blue goo and bounce right to the exit. Go through it and get in the next lift.
  62. Step out of the lift and jump down onto the concrete.
  63. You’ll find a twisted steal beam you can use to cross the murky water.
  64. Once on the other side, find the concrete pillar closest to the pipe with the blue arrow. Look at the top of the pillar (use zoom). There’s a small area you can hit with a portal. Put a blue one there and then an orange one on the base of one of the pillars. Get up there.
  65. Look to your left and you’ll see a room with a red podium button. You can put a portal on the floor and warp in there.
  66. Press the red podium button and blue goo will start falling from a tube. You can move the goo to other locations by putting one portal where the goo is hitting and another in the location you want covered in goo.
  67. If you look at the wall with the orange dotted line, you’ll see two giant metal steps to your right. Use portals to get some goo on the ground so that you can bounce up there.
  68. Once you’re as high as you can get, look across the room and find the emancipation grid.
  69. If you put some blue goo on the ground level, you can bounce across to where the grid is.
  70. Once you’re there, stick a blue portal to that angled panel. Now move around the emancipation grid (don’t go through it). Put an orange portal beneath the blue goo. Now some goo will shoot out of the angled panel and land on the metal floor across the pit.
  71. Now, while you’re on the high ground, shoot an orange portal at the low ground and jump through. You’ll come flying through the blue portal on the angled panel, bounce off the goo and land by the exit.
  72. Grab the lift and get to the next test chamber.
  73. Look around on the walls and find the blue line leading to the red podium buzzer. Put a blue portal on the spot that the blue goo is hitting and redirect some of it to the floor just below the button.
  74. Now bounce up there and press the button. You have just stopped the water that was flowing onto the little patch of metal floor. But it will start up again shortly so move fast.
  75. Quickly look to your left and locate the panel on the wall. Fire an orange portal at it. This will send some blue goo shooting at that spot that the water is no longer hitting.
  76. Now bounce off that spot and up to the next level. If the water hits the spot before you get a chance to bounce, you’ll have to try again.
  77. Pass through the emancipation grid and locate the angled panel. Now use portals to make some blue goo come shooting out of the angled panel.
  78. Look to the left of that angled panel. You need to shoot a blue portal at the top of one of those pillars above the metal beam. Put an orange one on the ground and get up there.
  79. Once you’re on the beams, fire an orange portal at the angled panel and then a blue one at the ground. Now jump through the blue portal and you’ll fly out of the angled panel, bounce off the goo and through an emancipation grid.
  80. Locate the two pillars that form a “U.” One of those pillars has an angled part. Do not leave the high ground. You want to shoot some blue goo at that angled part. You can do this by putting a blue portal on the pillar across from it and an orange portal beneath the blue goo tube.
  81. Once that’s done, put an orange portal on the ground and jump (you should not have left the high ground). You’ll come shooting out of the pillar on the left, bounce off the goo-covered kink in the pillar on the right and go flying up to another catwalk.
  82. Once you’re up here, look for a portal-friendly patch of wall on the pillar your catwalk is connected to. Above that is another patch of portal-friendly wall. Put one on the low patch, one on the high patch and get up there. The exit will be waiting.
  83. The next chamber features a cube in a glass case. You’ve got to get some blue goo on that cube, so find the spot where the goo is hitting and fire a portal at it. Now fire a portal to the ceiling above the cube. The cube will bounce out of its case when the goo hits it.
  84. Grab the cube and use the water to wash it off. Then set it on the red button.
  85. Follow the line coming from the red button to the lift. Get some blue goo underneath the lift and bounce up there.
  86. Now, while standing on the lift, use portals to get some more blue goo on the cube and it will bounce off the button, causing your elevator to move up. After getting off the lift, you’ll pass through an emancipation grid and get into an elevator.
  87. Immediately after exiting the elevator, look to your left. You’ll see a wall you can hit with a portal across a large expanse.
  88. Walk into the reception hall. There’s a portal-friendly piece of wall hidden just around a corner on the left-hand side. Put one on there and hop through.
  89. Go through the door and into the room filled with two large pipes.
  90. Look up and find the portal-friendly wall above the catwalk. Portal your way up to the catwalk.
  91. Up and to your left is a control room. If you look to the right of the control room, there is a portal-friendly piece of wall at the top of the wall, but you can’t hit it from where you are because it’s blocked by glass. Remember where that patch of wall is. This is going to get tricky.
  92. There are two portal-friendly pieces of ground below you. Fire a blue portal at the nearest piece of ground and an orange one at the farthest piece of ground. When you come out of that orange portal, look for the patch of wall directly opposite the control room.
  93. You need to hit that piece of wall with a BLUE portal while you’re in mid-air. As you fall back into the orange portal, you’ll come shooting out of the new blue portal you’ve made on the wall opposite the control room. Presto! You’re in the control room.
  94. Pull all the levers in the control room.
  95. Now walk through the emancipation grid and outside.
  96. Once outside, locate the yellow catwalk with the gate at the end of it. Stand at the edge of the catwalk and look at the gate. Now turn around.
  97. Look up the wall you are now looking at. There’s a catwalk you can portal your way to at the top.
  98. Once you’re up there, you can see the exit just beyond the Aperture Science sign.
  99. Look to your right and down and you’ll see an angled piece of concrete that’s portal-friendly. Hit it with a blue portal. Now fire an orange portal at the portal-friendly patch of ground below you. Jump through the orange portal.
  100. You’ll go flying through the air and land in the control room. You’ll find GLaDOS in potato form; grab her and activate the elevator control button.
  101. Now portal your way back to the catwalk you just jumped off of. You’re going to do it again.
  102. Line yourself up with the elevator. Turn around and shoot a blue portal as high up on the wall as you can.
  103. Find the portal-friendly patch of ground below you, make an orange portal and jump through. You will launch yourself right to the elevator.

die restart try again


On April 18, 2011 at 1:29 pm

Great game, got it two days early <3


On April 18, 2011 at 6:15 pm


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 ;)


On April 18, 2011 at 9:44 pm

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

Nova Rift

On April 19, 2011 at 12:24 am

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.


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!!


On April 19, 2011 at 11:45 am

im stuck on test chamber 4 coop with my friend were on the 4th test in the 4th test chamber. Anyone know how to do it?


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!


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(


On April 19, 2011 at 1:46 pm

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


On April 19, 2011 at 11:17 pm


You sir are a life saver!

I was stuck on this one for who knows how long…


On April 20, 2011 at 4:02 am

im stuck.

I can’t figure out for the life of me how to hit the button that is guarded by three turrets.the same place as nova rift above. If you want just email me at username then hotmail dot com.
big thanks

On April 21, 2011 at 1:12 pm

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.


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.



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.


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


On May 21, 2011 at 9:17 am

wow…finally it..what a game..thanx a lot for the vids..without some of them it would hav taken me ages to finish


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!!!


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.


On June 19, 2011 at 3:41 am

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


On June 30, 2011 at 5:37 am

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.


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!!!???


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 !!!!


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


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??


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.


On October 29, 2011 at 6:43 pm





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?


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?


On September 29, 2012 at 11:34 am

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


On December 17, 2013 at 10:55 pm

Its great :P
