Portal 2 Walkthrough

Chapter 9: The Part Where He Kills You

  1. You’ve fallen into Wheatley’s trap, but don’t worry, some white goo will appear and you can portal your way to safety.
  2. Shoot a blue portal at the goo that hits the platform you’re standing on.
  3. Fire an orange portal at the place where the white goo has struck the catwalk.
  4. Now run along the catwalk and through the door and emancipation grid.
  5. Keep following the catwalk to the place where it ends abruptly. Look down.
  6. There’s a portal-friendly piece of material down there. Put a blue portal on it.
  7. Look up and to the right. You’ll find a place where you can put an orange portal.
  8. Now jump into the blue portal.
  9. Follow the catwalk until the giant panel tries to crush you.
  10. Put a blue portal on the upper left part of the wall, past the gap in the catwalk.
  11. Now backtrack a little and find a portal-friendly wall to stick an orange portal on. Jump through.
  12. Pass through the emancipation grid and you’ll get a loading screen.
  13. Follow the catwalk until it gets blocked. Put a blue portal on the wall blocking your path.
  14. Look up, you can fire an orange portal through the grate and onto the ceiling.
  15. Jump through the blue portal.
  16. You’ll wind up in a room with a bunch of defective turrets. Find the exit and keep moving.
  17. Jump down to the lower catwalk and pass through the door and emancipation grid.
  18. When you see the targeting lasers of the turrets, stop and use the blue beam to get rid of the turrets.
  19. Just put a blue portal on the spot the blue beam is striking then throw an orange one behind the various turrets.
  20. When you’re done with that, set up a portal so that the blue beam shoots between the gap in the wall (the same wall where you sent the turrets.)
  21. Hop in the blue beam and float through the gap.
  22. Wheatley will try to kill you with a trap in the wall. Stay calm, look down and jump out of the beam as soon as you’re over the catwalk.
  23. Move through the emancipation grid.
  24. In the next room put a blue portal on the floor where the blue beam is striking. Then put an orange portal on the wall opposite the circular door.
  25. Float out of the door in the blue beam and Wheatley will try to crush you with a spiked panel.
  26. Look straight ahead and down slightly. There’s a portal friendly piece of wall. Hit it with an orange portal.
  27. You’ll fall into the new blue beam you just created and begin moving the opposite direction.
  28. Get on the catwalk and follow it through another door and emancipation grid.
  29. A section of catwalk will get taken out by a falling pipe but some blue goo will form a trampoline so you can bounce across.
  30. You’ll round a corner and see a bunch of red targeting lasers from turrets.
  31. Look at the place where the lasers hit the wall then look up. You’ll see a portal-friendly piece of ceiling just beyond some glass. Hit that with a blue portal.
  32. Now back up and find a portal-friendly wall and hit that with an orange portal.
  33. Jump through and you’ll find yourself standing near a red button. It starts the blue goo dispenser flowing.
  34. Put a blue portal underneath the blue goo dispenser.
  35. Now shoot orange portals at the wall directly to the right of where the turrets are.
  36. Now when you step on the red button, you’ll lob some blue goo at the turrets. Keep moving your orange portal and use trial and error to eliminate all the turrets.
  37. Now locate the angled panel hanging from a robotic arm in the ceiling, hit it with a portal and get over there.
  38. Step on the aerial faith plate and you’ll land on the catwalk.
  39. Hang a left and head through the door and emancipation grid.
  40. You’ll pass through an emancipation grid and into a room with a red button. Press the button.
  41. Now look out of the glass past the button. You’ll see a tube spit some bombs onto the ground.
  42. The glass is broken in the bottom left corner and you can shoot a blue portal onto the spot you just saw the bombs hit.
  43. Now locate the tube that’s carrying white goo in the room you’re standing in.
  44. Put an orange portal on the portal-friendly wall facing the tube (look up).
  45. Press the red button and the bombs will blow up the tube. White goo will splatter on the floor and allow you to portal out.
  46. Pass through the computer room, then through the door and emancipation grid.
  47. Head down to the conveyor belt then cross it to the platform with the red button. Push the red button. You’ll see more bombs falling.
  48. Shoot a blue portal at the floor where the bombs struck, then turn left and fire an orange beneath the tube carrying orange goo.
  49. Press the red button again. The tube will shatter and red goo will start spilling onto a spot on the floor. Hit that spot with a blue portal.
  50. Now hit the spot at the very end of the conveyor belt with an orange portal. The conveyor belt will get covered in goo and you can run right to the end of it. Do this and jump right through the portal at the end.
  51. Find your way down a corridor and into the next room.
  52. In the next room, locate the portal-friendly patch of floor. There’s a blue beam directly above it.
  53. Now locate the corridor you came in through. There’s a portal friendly patch of wall at the end of it. Shoot a blue portal at this wall.
  54. If you left your orange portal beneath the orange goo you should have just created a nice runway for yourself.
  55. Now put an orange portal on the portal-friendly piece of floor.
  56. Run down the runway and into the blue portal you put at the end of the corridor.
  57. You’ll come shooting out of the orange portal and into the blue beam which will carry you to another catwalk. Jump down onto the catwalk and follow it through a door and emancipation grid.
  58. Now look up and fire a blue portal through the grate and onto a portal friendly wall. Get up there.
  59. After a loading screen, look up and locate a portal friendly piece of ceiling. Hit it with a blue portal.
  60. Shoot a blue portal on the ground and hop through.
  61. Follow the catwalk and take a right when you hit the defective cores.
  62. Now find the white Aperture box with the jack in it and plug GLaDOS in. Get ready for the final showdown with Wheatley.
  63. Wheatley’s first move is to throw bombs at you. Stand in front of the white gel tube and then move when he attacks so that he blows up the gel tube.
  64. Now you can trick him into shooting bombs at himself. Put a blue portal on the ground just behind you and an orange portal on one of the panels. Then move when he shoots bombs at you.
  65. The bombs should go into the blue portal, come out the orange one you stuck on a panel and strike him.
  66. Watch where he’s holding his shields, if they are in front find a panel behind him, put a portal on it and then trick him into shooting himself.
  67. If he has no protection below him, try putting a portal on the ground so that bombs come shooting up at him.
  68. Once you’ve hit him with a bomb, he’ll be incapacitated for a minute and GLaDOS will throw you a defective core.
  69. The first one will be up on the catwalk.
  70. Locate the white goo panel just above the catwalk and portal up there.
  71. Grab the core and some blue goo will spill on the floor. Bounce up to the blinking red light on Wheatley and push the core at the light.
  72. He’ll wake back up and you’ll need to hit him with more bombs.
  73. When you hit him this time a second defective core will begin swinging back and forth over a blue patch of goo.
  74. Portal back up to the catwalk, bounce on the goo and catch the second core.
  75. Locate the blinking red light on Wheatley, then bounce off a blue patch and push the second core in.
  76. Hit Wheatley with some more bombs and the last core will appear along with some red goo. Locate the red goo first and the core will be swinging over it.
  77. The red goo will form a runway leading to a white goo-covered wall. Put a blue portal on that wall.
  78. Now put an orange portal on the ground directly below the last core.
  79. Back up to the end of the runway and run into the blue portal. You’ll come flying out and be able to grab the last core.
  80. Bounce off a blue patch and push the core at the last blinking light.
  81. Now you’ll have to push the “stalemate resolution button” again.
  82. It’s behind a grate this time. Fire a blue portal into the ceiling beyond the grate and get in there.
  83. That’s it. Enjoy the cut scene and shoot for the moon when you get the chance.

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 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
