Portal 2 Background Info:
A mere curiosity when it was initially published, the original Portal quickly became a full-fledged phenomenon, as gamers and dilettantes alike recognized the genius of what Valve had created. Now Portal 2 has arrived, and the secret is well and truly out. Though the first installment was notable for its brevity, the sequel is hugely expanded, promising both singleplayer and co-op modes, each riddled with new mechanics, puzzles, and challenges.

@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.

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!!

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!

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.

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

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

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?
