Chapter 3: The Return

  1. The next test area has an aerial faith plate in the center of the room. Bounce on it a few times and GLADoS will lower the ceiling.
  2. Put a blue portal on the ceiling directly above the faith plate. Put an orange portal on the ceiling beyond the wall that’s blocking your advance.
  3. Now jump on the faith plate again and you’ll be beyond the wall. Walk around till you find the laser. Put a blue portal on the panel directly across from where the laser is shooting at.
  4. Now head back down to the faith plate. Put an orange portal on the ceiling above the plate then use the plate to jump through it.
  5. Press the red podium button. Then but a blue portal on the angled panel across from the one you put a portal on before.
  6. Go jump through the orange portal on the ceiling again. Then grab the redirect cube and use it to focus the laser on the wall that you can put portals on.
  7. Put a portal on the wall where the laser is now shooting, then run around to the other side of that wall and put a portal opposite the laser target.
  8. There’s one more angled panel by the laser’s new redirected course. Put a blue portal on that angled panel and go jump through the orange portal in the ceiling again.
  9. Reset the lasers on either side of the wall below you (without stepping off the high ground) so that the laser once again hits the target. You’re done with this chamber.
  10. The next room has another aerial faith plate in the center. Keep going past the faith plate and look down the ravine. Shoot a blue portal at the floor in the bottom of the ravine.
  11. Now make a 180 degree turn. Fire a portal as high as you can on the wall you are now staring at.
  12. Jump through the portal you put at the bottom of the ravine. You’ll end up sailing across the ravine.
  13. Grab the cube and portal your way back across the ravine.
  14. While holding the cube, step on the aerial faith plate. You’ll be catapulted up to an area with a laser. Use the cube to block the laser. This will lower the wall.
  15. Now step on the aerial faith plate again and you’ll bounce a few times, then stop on an area with a red podium button. Go push the red podium button.
  16. A redirect cube will bounce up to where you are. Grab it and jump back down to the area where you had obstructed the laser.
  17. If you are looking at the spot where the laser hits the wall, make a 90 degree turn to your left. Put a portal on the wall you are now looking at.
  18. Use the redirect cube to fire the laser into the portal you just created. Grab the plain cube that you had originally used to block the laser. Now jump back down and jump on the aerial faith plate.
  19. Put the plain cube on the red button. Chamber complete.
  20. This next chamber involves light bridges. Put a blue portal on the wall that the light bridge is aimed at.
  21. Put an orange portal on the wall across the chasm. Now you can walk on the light bridge.
  22. Walk about halfway across the chasm and stop. Turn to your left. Fire an orange portal at the wall (fire it at the lowest part of the wall).
  23. You’ll fall onto the new light bridge you created. Do a 180 and walk to the end of the light bridge.
  24. Turn to your left and put another orange portal on the wall below you. You’ll fall a little way again and land on the bridge.
  25. Walk toward the portal you just created. Stop before you go through it. Make a 90 degree turn to your right. Jump and fire another orange portal at the wall you are now facing.
  26. Turn around and walk to the end of this light bridge. Grab one of the falling cubes.
  27. Turn around again and walk through the orange portal while holding the cube.
  28. Face the exit door. Now turn right and fire an orange portal at that wall.
  29. Grab your cube and walk through the blue portal at the end of the light bridge. Keep walking until you get to the red button.
  30. Put the cube on the red button.
  31. Fire an orange portal at the wall to the right of the exit door.
  32. Now walk back outside the glass. Turn toward the point where the blue bridge originates (not one of your portals, the actual source).
  33. Fire an orange portal at the wall just below you. The bridge will appear, walk on it and go through the portal.
  34. Now fire a portal at the wall to the right of the exit door. Walk across it and out the door.
  35. Wheatley will show up on the way to your next test chamber to inform you that you’ll be breaking out soon. After he talks to you, you’ll be able to proceed to the next chamber.
  36. Fire a blue portal at the wall directly in front of you when you enter the next chamber.
  37. Now fire an orange portal above the blue bridge to your left. Step through the blue portal and onto the bridge.
  38. Fire an orange portal at the wall where the blue bridge strikes it. Now walk through the orange portal.
  39. Now fire fire another orange portal at the wall beneath the chute where the cubes come out. Press the red podium button to get a cube.
  40. Grab it when it lands on the bridge, and walk halfway out onto the bridge over the chasm. Fire an orange portal through the bridge and into the wall (towards the red podium).
  41. You’ll land on the new bridge and it will take you right to the red button. Drop the cube on the red button and exit the level.
  42. There’s a turret in your way in the next chamber. Portal behind it, pick it up and knock it over.
  43. The next turret can be disposed of by creating a portal underneath it.
  44. Head up the stairs, there’s more turrets behind a pane of glass. Create portals over their heads and drop cubes on them.
  45. There’s three more turrets in the next room. You can put a portal beneath one of them. Drop cubes on the other two.
  46. Drop a cube on the red button. There’s a bunch of debris in you way as you exit the room. Jump down into the pit. Make your way to the next test chamber.
  47. In the next chamber you’ll have cones that you need to hit with the laser. The laser must be hitting all the cones at once to activate the door.
  48. Grab the redirect cube and redirect the laser so it fires through two of the cones.
  49. Now find where the laser ends, put a portal on that wall and put another portal in front of the last cone. This will open the door. Chamber complete.
  50. In the next chamber, put a blue portal on the wall to the left of the three turrets. Now put an orange portal on the wall that the blue bridge is hitting. This will create a barrier that will block the turret around the corner.
  51. Face the single turret that is blocked by the light bridge, behind it to your left is a wall you can put a portal on. Stick an orange portal on that wall and then quickly jump into the blue portal to your right before the turret can shoot you.
  52. Look back towards the source of the light bridge. To your right is a wall place a blue portal on that wall and the light bridge will protect you from the turrets by the cube.
  53. Step on the red button between the two pillars. A glass wall with two turrets behind it will begin to lower. Before the wall can come all the way down, shoot a portal on the wall behind the glass. Now shoot another portal on your side and you can sneak behind the turrets and disable them.
  54. Shoot two portals inside the glass and GLADoS will lower the glass for you. As the glass goes down quickly move to the safety of the pillar or the turrets will kill you.
  55. Above the glass wall that trapped you is a wall you can stick a portal to. Shoot a blue on up there. Now go way back to where the blue bridge hits the wall and shoot an orange portal at that point.
  56. Now step on one of the aerial faith plates. The bridge will stop you on a catwalk. Walk across the catwalk and drop down on the sentry guns, disabling them.
  57. Take the companion cube. Put it on the red button. Exit the chamber.
  58. Watch out for the turret hiding in the grate in this next chamber. Move quickly past it and toward the red button. Stepping on the red button will activate the laser
  59. If you put a blue portal on the ground where the laser is striking and an orange portal on the wall the turrets are facing, all the turrets will die horribly. Do this and then step on the red button.
  60. Grab the plain cube and set in on the button. Then grab the redirect cube and fire it through the glass. Take out all the turrets and then line it up with the laser target.
  61. Exit the chamber.
  62. There’s a blue bridge in the next chamber. Fire a blue portal at the wall the bridge is striking. Put an orange portal at ground level and walk through it.
  63. Grab the cube, to the right of the laser target there’s a wall you can put an orange portal on. Do this.
  64. Now walk through the blue portal with the cube. Set the cube on the blue bridge directly above the red button, so that it blocks the laser. Blocking the laser will lower an elevator panel.
  65. Walk over to the elevator panel and get on. Now fire a blue portal at any portal surface. This will cut the bridge, causing the cube to fall and land on the red button while simultaneously unblocking the laser and causing the elevator to go up.
  66. Exit the level.

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 6:08 am

I beat the co-op with a friend and the single player all in one night. Started a lil after midnight when i got the game and finished up around 2 that afternoon. Some of the puzzles were challenging but thats the point. Just play the game people


On April 21, 2011 at 8:38 am

On April 21, 2011 at 9:06 am

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
