@DarkLink46: Hehe, I guess most of my chambers in the "hard" category use some rare trick that you don't often see in other chambers ^^ But yeah, glitches can't always be prevented, so I guess you will find easier solutions using them sometimes.

Lol, because I didn't spot the intended solution, I ended up needing the companion cube from the extra area to solve this. Really good puzzle. I'm glad I found a way to solve it myself before looking in the comments. There's no way I would have thought of using the two cubes like some of the walkthroughs show, I spent so long trying to solve it, if it didn't occur to me after that, I don't think it ever would XP.

Sorry this got complicated XD. So I had employed the floating cube glitch to keep the light bridge active, and as I say took the regular and companion cube back into the main room, put a portal on the wall round the corner from the exit door and another in line with the laser cube switch. Then I sat at the top of the slope next to the exit door and fired my first portal at the end of the laser, respawning the laser cube. I then put the portal back round the corner again, set the laser cube to hit the funnel reverser, put one of the other two cubes on the light bridge deactivator, jump through a portal to round the corner, went over the slope and got out...

Oh god, I really struggled with this one. Pretty sure I didn't solve it as intended. I found the secret surface above the door, triggered the laser receptor, Went across the light bridge, threw all the franken cubes onto the above ledge, used them to get the companion cube. I put a portal up by the exit door, placed another opposite the laser cube switch (had to jump in using two cube stack).

@mood3rd: You wanted TWTM chambers? Check this page ^^

for me, yes.
but for those with the required skills, that want a good challenge, fine.

XD Well I probably thought about making that the main puzzle in the beginning... But then decided that it was too damn hard X)

thankyou for the hint.
but as you've seen, from my video.
my portal placement is not that good.
I nocliped to see where I had to aim, & still could not do it.
even while coming out & going into the floor portal.
which I presume is the only way to get the correct angle.
getting an easter egg off you, is harder than getting cake, from Glados :)
easter egg = expert level

@mood3rd: Hint: You have to find a way to portal under one of the angled panels ;)

I put it back in my list.
but I could not even see a way out of the main chamber.
so I might have to go on a diet.

Okay, I tried again and... I think the easter egg might be harder to solve than the actual chamber XD There is a lot of back and forth travel, and finding hidden white surfaces, and placing portals in the right order, etc...

Honestly, I don't even remember where is the easter egg X) Will play the map one more time and see if I can find it :p

or those who want a laugh at my expense :)
ok, that's fine.
but they might get bored, before actually seeing the solution ?
unless still laughing :)
did not get easter egg.
but as it is near Christmas, maybe a piece of cake ?
which this was not :)

XD Watching this walkthrough is hilarious X) Bad luck was on you that day ^^" Anyway if you're okay with that I can add the video to this page as a solution for those who are stuck ;)

good hard (as you say in description) map.
timing gave me trouble, but enough time given.
the reflector would move slightly on the button.
causing miss alignment.
but most problems of my own making.
I was slow & my placement of portals was bad.
I did a spoiler video walkthrough, of 1st successfull attempt.
had tried previously & failed.
but this time I had figured out all exept where to place portals.
video of me having a bad day: (you may want to skip to last min)

Oh, so it involves the same steps as the expected solution but this is actually NOT the expected one XD Will see if I can fix it easily...

Sorry bout that. Try again.

Hem your video is private for now, could you set it as public ? Added your map to the list ;)

I don't know why I had such a hard time aligning the cubes this time but all I saved was the ending. The other thirty minutes is in the trash. Please feel free to try one of mine if you like. See ya round the workshop.

My solution.
Delete please.

Thanks a lot for playing stormsend ^^ (I finally know that someone managed to do it XD ) If you could record a walktrough video it would be perfect :)

Finally made it. Took me a while though. I like laser puzzles. Great logic problem. I concentrated on the main room. Didn't go anywhere else. Will make a walkthrough if needed but I feel like it's your intended solution. Thank you and I'll see ya round the workshop.

Okay so the method you describe here is the expected one ^^ And if you placed your portals at the correct place ( that's where I fear that the correct angle may be too hard to reproduce... ), you should be able to destroy the laser cube... Anyway don't forget that you also need to disable the light bridge before doing that ;)
About the hidden area, you can go there and come back if you want, that wont help you to solve the main puzzle X) You can also come back with some cubes and that still wont help (in theory ^^).

hah, I tried to laser the piston target with that little tile on the floor, which required that I stand right in the corner to place the portal. portal opens, i bounce on the laser, die :)
I put the laser cube on the button so that it's rotated 45 degrees and therefore doesn't trigger the button. this raises the beam enough to hit the piston target. then I would set the second cube on the laser cube so that if i kill the laser cube it drops onto the button properly, but I can't find a way to get the laser into the laser cube target while on the piston platform. Anyway, if you put a portal on that panel near the exit behind the angled panel and then use it to get back there after doing stuff in the room, that breaks the level wide open (assuming it's possible anyway)

By the way, how exactly did you die using the corner surface ? O_o Some glitch of the game ?

:) Well I worked hard to restrict the solutions to the one I expected yes :p But I'm afrait that it may be too hard and pixel precise now :/ Even if you have some delay to perform the good portal shots, it is still hard to do...
The surface on the floor is the way you go out of the main room ^^ Some trick involved here to be able to portal on a surface you can't reach without this floor surface ;)
Could you describe the trick you talk about using [ spoiler ] tags ? Or screenshot ?

I'm pretty amused now, as I've just screwed around in the main room for about 10 minutes and found about a dozen variations of a potential solution, only for it to be foiled by the geometry of the room. I can tell you put a lot of work into this

I was able to beat it while bypassing the piston platform entirely via the hidden room, which is the only solution I discovered. I had no noclip though, since I still haven't managed to make that shot through the two angled panels. I did rediscover a fun trick I'd forgotten about, which I thought was your intended solution until it didn't work, so that was fun. I also tried using that white floor tile in the corner, and then died. Is it there for a reason?

@Ravoria : Thanks for playing! And almost completing it :p (I deleted one of your coms because I think it could be part of the intended solution but I'm not really sure... Added your map to the list anyway)
So about the first point, I didn't realised that you could see far away from this point but you are supposed to see that there is some place where you can portal through the angled panel close to the floor, in the direction of the exit and this is the intended way to reach this area ^^ Anyway this is part of the optionnal challenge to get the companion cube and don't change the main puzzle.
And about the second part, activating the piston to be able to walk on is the first thing you have to do and using the laser cube to redirect the laser on the angled panels is the right way to do it, anyway you are not supposed to be able to activate the cube button AND the laser at the same time, and even if you can do it it wont help to solve the puzzle.

I'm throwing in the towel for now, the one bit of feedback I have to offer is that if you look through the panel near the exit, the fog in the distance looks like a portal surface. Or at least it did to me. imo anything that inspires people to noclip around kinda ruins the level because they just keep noclipping after, just my two cents. I'll come back to this later.

Salut. je n'arrive pas du tout a comprendre la logique de tout ces panneaux inclinés....c'est un peu comme dans ta map Infini Feeling dans laquelle je suis coincé.

Okay so Mackinley you seems to be the only one able to complete it for now... Could you explain quickly your method using [ spoiler ] ?

Oh God, this had to be too hard for me. I spent over 30 minutes trying to figuring this one out and achieved nothing except this Which is gave me nothing but lolz

cool level

Arf, so all the franken cube part is part of the optional challenge, you don't need to go there to complete the map ^^
About the main puzzle, the first thing to figure out is How to be at the top of the piston AND open the exit. Then you are really close to the solution, you only need to restart the process and activate the laser relay to disable the light bridge.

So this guy storms into my chat and tells me to play his map, and obviously it's the only right thing to do, so I gave it a shot. Within 10 minutes I had no clue what to do. I did manage to get to the part with the frankencubes in the hidden area and did a few portals here and there and somehow ended up back in the main room. Ragequit, please help D:

PS: I think I broke a thing.
