Portal 2 Walkthrough

Table of Contents

Chapter 7: The Reunion

  1. In the next chamber locate the platform with the red podium button on it is located high up in one of the room’s corners.
  2. Throw a portal on the ceiling above the platform and get up there. Press the red button: it will start some red-orange goo flowing. The orange goo makes you slide rather than bounce.
  3. Remember how you moved the blue goo to places you wanted using portals? Use this same trick to cover the runway leading up to the ramp in orange goo. If you trace the runway back to where it meets the wall, that’s the best spot to put a blue portal on. Now put an orange portal portal beneath the goo tube.
  4. Make sure the ramp and runway are completely covered.
  5. Before you take off, shoot a blue portal at the ceiling above buzzer.
  6. Now get a good running start and hit the ramp full speed.
  7. You’ll go flying to into another passageway. Follow the arrows until the catwalk dead ends. Now make a 180-degree turn and fire an orange portal at that wall. Jump through the portal.
  8. You should land right next to the red podium button. Put a blue portal beneath the goo and press the button. Now launch yourself off the ramp again.
  9. Great, now run down to where the catwalk ends and just keep going. There should be orange goo all over the place and you’ll slide right across the gap.
  10. Now you’ll find a cube behind some glass with a hole in it. Fire a portal behind the cube and another portal on the wall behind you. Then grab the cube.
  11. Fire one more portal back the way you came and jump through the one on the wall again. Now make your way back to where the ramp is.
  12. Set the cube on the red button. This will change the angle of the ramp. Launch yourself off the ramp again.
  13. Now, find the portal-friendly piece of floor and put a blue portal on it. Put an orange portal back where the ramp is. Jump through the blue portal.
  14. Now put an orange portal on the wall where it meets the runway. This time, start at the ramp and run through the portal on the wall (basically using the ramp in reverse).
  15. When you come flying out of the blue portal, tag the button located at the apex of your jump.
  16. The door will open and you can head on through the emancipation grid.
  17. In the next chamber the floor beneath the goo dispensers is covered with a grate, but you can still shoot portals through this grate.
  18. First, look across the gap and you’ll see a portal-friendly piece of wall on a pillar. Stick a blue portal to this and an orange portal to floor beneath the orange goo dispenser. No press the red button next to the dispenser and you’ll cover the ramp with goo.
  19. Now look up and you’ll see a piece of ceiling tile with a red “X” on it. Fire a portal up there and connect the other portal to the blue goo dispenser.
  20. When you’ve finished, what you’ve created will be an orange runway with a blue trampoline at the end of it.
  21. Start running on the orange runway and you’ll bounce when you hit the blue. You’ll sail safely to your destination across the ravine.
  22. Now, walk around the pillar and find the portal-friendly piece of wall on the other side. Fire a blue portal at it.
  23. Now look up. Fire an orange portal at the wall that is located higher up on the pillar.
  24. Walk through the blue portal.
  25. Now walk around to the other side of the pillar and fire an blue portal at any portal-friendly piece of wall back by the ramp.
  26. Once you’re back on the other side fire a blue portal at the wall that you hit when you bounce of your trampoline ramp.
  27. Now bounce off of your trampoline ramp. You should fly into the blue portal then out the orange portal on the other side of the pillar and right to the elevator.
  28. In the next chamber, align yourself so that you’re standing between the two goo dispensers. If you look to your right you’ll see a portal friendly piece of wall that’s below an angled portal-friendly piece of wall. Put a blue portal on the portal-friendly piece of wall and get over there.
  29. Now put a blue portal on the angled piece of wall just above the flat piece of wall. Put an orange portal beneath the blue goo dispenser. You’ve just created a trampoline that you can’t see but you’ll be using it momentarily.
  30. If you look at the ground, you’ll see that there are red arrows pointing toward the wall. You need to cover them with orange goo. Throw a blue portal on the flat piece of wall that the red arrows are pointing at. Put an orange portal beneath the orange goo dispenser and that should do the trick.
  31. Now put the orange portal on the angled piece of wall. At this point your orange portal should be stacked on top of your blue portal.
  32. Back up to the end of your runway, then run into the blue portal. You’ll come shooting out the orange one and bounce off the trampoline you created earlier.
  33. You’ll land on a suspended platform with a cube on it. Grab the cube and drop down to the catwalk below you.
  34. Look to the left of the runway you created earlier. There’s a portal friendly piece of wall and a red button down there. Get down there.
  35. Set the cube down, but NOT on the red button.
  36. First put a blue portal on the ground beneath the piece of ceiling that is held by the robotic arm. Now put an orange portal back by the runway you created earlier.
  37. Jump through the blue portal. From here, you should be able to see the blue goo dispenser. Hit the ground beneath the dispenser with an orange portal. This should get some blue goo on that piece of ceiling above your blue portal.
  38. Now put a blue portal back by where your cube is and put an orange portal on the wall behind you.
  39. Jump through the orange portal. Place your cube on the red button. This will cause the robot arm to flip the panel with the blue goo around. You’ve created another trampoline.
  40. Portal your way back to the runway you created earlier. Now face the wall at the end of your runway. Look up and to your left. There’s a ramp up there with a piece of portal-friendly wall in front of it. Fire an orange portal onto the wall in front of that ramp.
  41. Now throw a blue portal under the orange goo dispenser. You’ve just covered the ramp in orange goo.
  42. Stick your blue portal back on the wall at the end of your runway. Now back up to the end and run through the portal. You’ll bounce off the trampoline and right to the exit.
  43. When you get off the elevator, head through the emancipation grid. Make your way into the building and locate the next emancipation grid which is connected to a catwalk above you.
  44. Portal your way up there and pass through the grid.
  45. You’ll see a sign that says “gamma” and has an arrow pointing right. Look right and there’s a portal friendly wall across a large expanse.
  46. Portal your way over there and pass through the emancipation grid.
  47. Follow the catwalk into the control room, where you’ll find three gel pressure control levers. Pull all three of them.
  48. This will start the red, blue and white gels flowing in the room. It will also activate some pneumatic crushers on the catwalk. Don’t get caught under those.
  49. The white gel is a portal conductor gel. This means that any surface with white gel on it is now a portal surface.
  50. Some white gel has splashed on the ceiling just above a suspended piece of catwalk. Hit it with a portal and get up there.
  51. Look around until you find the “Keep Out” sign. There’s some blue goo in the pit below the sign, you can use it to bounce over to that catwalk.
  52. Move through the emancipation grid and use the orange goo on the catwalk to slide through the pneumatic crushers. Go through the door and out onto the catwalk.
  53. A segment of the catwalk is missing. Look toward the door on the other side of the catwalk.
  54. Do a 180, behind you is an angled, portal friendly piece of wall. Stick a blue portal on it.
  55. Now go back inside and set up an orange portal on the other side of the crushers. Wait till the crushers are raised, then run down the orange goo covered runway and through the orange portal.
  56. You’ll shoot across the broken catwalk and land safely on the other side.
  57. Once inside the building, locate the portrait of Cave Johnson. There’s a door to the right. Go inside and push the red button. This will open the door to another catwalk.
  58. Take a right at the “Please Do Not Test If…” sign. Get in the elevator.
  59. You’ll enter a room with white goo spilling onto the floor. Throw a blue portal on the spot where the white goo is hitting the ground.
  60. This next part is just trial and error. Start throwing orange portals on different areas that the white goo has hit until you get some of the white goo outside the enclosure, then portal out.
  61. Locate the angled panel with the spotlight over it and get some white goo on that.
  62. Near the angled panel are three large pillars. Locate the pillar with the catwalk at the top. You need to get up there.
  63. Get some goo on the wall of one of the pillars that is facing another pillar.
  64. Once you get some goo on the pillar wall, you can put a put a portal on that pillar and have the white goo shoot at the pillar facing it. The goo will get a little higher up. Then repeat the process and make the goo slowly climb the pillars until you can portal up to the catwalk.
  65. Once on the catwalk throw blue portal on the goo covered, angled panel. Now throw an orange portal on the ground. Jump into it from the catwalk.
  66. You’ll go sailing through the air and land on another catwalk. Follow the catwalk and pass through two sets of doors and an emancipation grid.
  67. Make your way through the building and you’ll come out the other side and find yourself standing in front of a pit.
  68. Put a blue portal on one of the walls in the pit. Then look up, you may need to zoom but you’ll find a portal friendly wall above the highest catwalk. Get up there.
  69. Look up again, you’ll see another catwalk above you, portal your way up to this one too.
  70. There’s a stopped elevator here. The floor in the elevator is portal-friendly and there’s a hole in the elevator’s roof directly above it. Put a blue portal on that piece of floor.
  71. Exit the elevator and step to your left. Step to where the catwalk ends. Now look down. Put an orange portal on the ground below you and jump through.
  72. Press W as you come shooting out of the elevator floor. You’ll wind up a few levels up on a wooden board. There will be writing on the wall that says 2900M.
  73. Next to the wooden board, there’s a portal-friendly piece of floor. Put a blue portal on it. Now put an orange portal on the floor of the elevator and jump through.
  74. As you reach the apex of your jump coming out of the blue portal, look around for a piece of angled, portal-friendly wall. You can bounce back and forth between your portals a few times while you’re looking.
  75. When you find it, tag it with an orange portal and the next time you fall through your blue portal you’ll come shooting out of the angled section. You’ll land on a catwalk with a door, head on through.
  76. Make your way back outside and locate the four pillars. Look up and you’ll see that you can portal onto the beams that connect the pillars.
  77. Get on the beams and then look around for a catwalk that’s attached to a door. Put a blue portal on the angled piece of wall above the door. Then put an orange portal on the ground and jump through from the pillars.
  78. You’ll go flying up to an even higher level, this one will have some blue goo dripping onto the ground. Fire a blue portal at the spot the blue goo is hitting. Now put an orange portal on the angled piece of wall that you came flying out of.
  79. The goo will launch out of the orange portal and hit a piece of wall, creating a trampoline.
  80. Repeat the earlier process of putting a portal on the angled piece of wall and then jumping through an orange portal on the ground.
  81. This time when you come flying out of the angled piece of wall, you’ll bounce off the trampoline and up another level.
  82. On this level there’s one piece of portal-friendly ground. Find it and put a blue portal on it.
  83. Now drop down one level. Find the ground where you jumped into the portal last time, put another orange portal there and jump back through.
  84. As you come flying out of the blue portal look ahead of you and you’ll see some portal friendly ground behind some metal cross beams. Hit that ground with an orange portal.
  85. After you fall back through the blue portal and come shooting out of the orange portal, press W or simply fire an orange portal somewhere else so that you don’t fall back through it.
  86. Once you’ve landed safely, you’ll see an emancipation grid. Go through it.
  87. You’ll find yourself in a room with all three types of goo being dispensed.
  88. Stand between the orange and white dispensers and look toward the blue dispenser. You should see a flat wall with an angled section above it. Neither one are portal-portal friendly and the first step is to fix that.
  89. Look up above the angled section of wall and you’ll see a grate with a piece of portal-friendly ceiling behind it. Tag that with a blue portal.
  90. Now put an orange portal beneath the white goo dispenser. This should cover both the angled and flat sections of the wall with goo.
  91. Now put a blue portal on the flat part of the wall which is now covered with white goo.
  92. Put an orange portal beneath the orange goo dispenser. This will create a runway leading up to where the blue goo is dripping.
  93. Put an orange portal on the angled part of the wall. Then put a blue portal on the highest flat part of the wall, just below your orange portal.
  94. Back up to the end of your orange goo runway and run toward the blue goo dispenser. When you hit the blue goo you should bounce into the blue portal and come shooting out of the orange one.
  95. Once your up here, you’ll see you need to create two trampolines to get to your final goal.
  96. You’ve got two pieces of portal-friendly floor where the trampolines need to be.
  97. Fire a blue portal at the first patch of portal-friendly floor (you can shoot through the grates on the floor). Now fire an orange portal under the white goo dispenser. White goo will come out and make a portal-friendly surface on the ceiling.
  98. Fire an orange portal at this new portal friendly surface, fire a blue portal beneath the blue goo dispenser. This will create a trampoline.
  99. Repeat this process with the second piece of portal-friendly floor.
  100. Now you’re all ready to go. Drop back down to the lower level, set up a blue portal on the highest part of the flat wall and an orange one on the angled wall above it.
  101. Back up to the edge of your runway, run down it and hit the blue trampoline beneath the dispenser. You’ll fly out of the orange portal, bounce on both the trampolines you created and land safely at your destination.
  102. Walk around the pillar and you’ll see some white goo dripping on the ground.
  103. Look up and you’ll see a portal-friendly piece of wall behind a grate. Fire a blue portal at it. Now fire an orange portal the ground that’s covered in white goo.
  104. Jump through the orange portal.
  105. Once you’re up here walk to the shaft with pipes running down it. Look up and to the left. There’s another piece of portal-friendly wall behind a grate. Hit it with a blue portal.
  106. You should still have the orange portal beneath the white goo dispenser, at this point the inside of the shaft should be converted into portal friendly surfaces by the white goo.
  107. Portal your way up as far as you can. You’ll see a small railing that you can stand behind. Try to portal your way over there.
  108. Eventually you’ll see some portal friendly wall behind a grate at the top of the shaft. Hit it with a portal and warp behind the grate.
  109. Look up at the catwalk and find the place where it leads to a door. There should be a single light hanging over the door. You can put a portal on the wall above the door. Get up there.
  110. Now search the upper corners until you see the catwalk with the words “Gel Pump” written in yellow. Look at the wall directly opposite those words.
  111. Right where the wall meets the ceiling is a piece of portal-friendly wall. Stick a blue portal on it.
  112. Now walk along the catwalk toward the point where the 3 pipes disappear below the grate. Look down but don’t jump down to the grate.
  113. On the ground level there’s a piece of ground that’s portal friendly, put an orange portal on it and jump through.
  114. You’ll catapult over to the “Gen Pump” catwalk.
  115. Walk into the control room and push the “hatch override” button. You’ll have a brief conversation with GLaDOS.
  116. A lift type contraption will lower itself out of the hatch in the ceiling. Get to it and get inside.
  117. After it pulls you up, you’ll find a staircase, then pass through an emancipation grid and get in an elevator.

@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 ;)

stuck

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

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!!

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?

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

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.

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

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?
