@ZAPAX Ty for the positive feedback, and enjoy building!

Thanks Ebbzylon for your masterclass. Very usefull. I'll keep it in mind when I create my chambers. Thanks a lot

True. Often been using that to "walk" over "obstacles", such as flip doors, etc.

Your chamber got me thinking, something you might want to add to this chamber is the ability to land on an inset platform by creating portal to the side and slightly above said platform. I'm not sure I've explained that well so i published an example for u (see below)

It's not a glitch as such, but because it would be impossible to do in reality many inexperienced designers overlook this potential bypass to their intended solution.

@snas Thanks for the feedback! Yeah, I tend to get irritated at maps that kills me too!
I guess I could replace the goo with an empty pit and a jump platform back to the entry point, especially since this is just a demo room.

cheers

Good idea to publish something like this. I've had the game for years and wasn't aware of the issue with the Fizzers and forgotten about that weird glitch where the cube passes straight though the mesh.

My only criticism is that it is quite easy to misjudge the jump in the last room and end up in the water. I always try to avoid using lethal components where there is a reasonable likelihood of them actually killing the player, especially as the player gets farther though the chamber.

did not fixed? really?
Ebbzylon  [author] 24 Dec, 2014 @ 8:05pm 
@SalbasuFilms, have look at the first comment. It contains links to videos that sho how to pass each room (assuming that Valve did not fixed those exploits since then)
Boobie and vagene 24 Dec, 2014 @ 12:29pm 
how do i pass the 1 room?
TS_Mind_Swept 18 May, 2014 @ 8:54pm 
omt, that's nuts! XD and why don't u test it to see if they still are? really cool though. 9/10 just for knowing how to do that. :p
Ebbzylon  [author] 18 May, 2014 @ 4:17pm 
no problem, scroll down to last comment page (the first comment entered) contains links to the videos u wanna see. (I do not know if those exploits are still in effect - I havn't played portal 2 in a while)
TS_Mind_Swept 18 May, 2014 @ 4:12pm 
i have no idea what to do, i was noclipping just to look around, and i couldnt figure it out, i want to see a video of someone doing it. :D

Yeah right, commonly known what room 5 now need. Remembers me on my " Exchange " that I think I fixed and I have no answer from you yet.
Ebbzylon  [author] 21 Dec, 2012 @ 10:13am 
@Reiman
room 4: Fixed. TY.
room 5: TY for reporting the patch. Indeed, I could not get the glitch from the room 5 to occur anymore! Hurray! I replaced the room with a new one built around another well known bug.

re: glitches - Indeed, that's exactly why I named this map so that it is obvious it is built around bugs that could be fixed over time.

cheers

Not bad, but I crossed room 4 with the same trick as room 3 ;)
And room 5 didn't work for me like in your video, so I stuck. Is there a chance, Valve did an update on that? So I would exchange room 5 by 6. Room 6 I already knew.
I just can advise everyone: don't build a puzzle solution on glitches, as they may get patched or somebody gets frustrated on them when they won't work for him - just try to avoid them.
Cheers!

@Shadow
thank you. Not sure how it happens. Possibly a race condition in the code.

@henpitts
thanks

Very nice map. I got stuck on the room with the cube and the annoying slanted panel for a while but then I got the glitch and it somehow worked. o_O how does it do that
henpitts 23 Sep, 2012 @ 1:49pm 
The double bump is the worst. The others are what the software department I work with would call features. Just kidding, but this is a great list of exploits I will be looking for. Good work.
Ebbzylon  [author] 4 Sep, 2012 @ 3:52pm 
Thanks.

Yeah, that particular glitch, I discovered while testing one of my maps. I was quite upset cuz it allowed to bypass half of the puzzle! :-P
Geneosis 4 Sep, 2012 @ 6:40am 
Well I saw it and... How the hell is this working XD Nice glitch, will try to remember it :p
Geneosis 4 Sep, 2012 @ 6:39am 
Nice glitch pack ^^ And cool way to generate a "broken cube dropper" you used with a light bridge ;) Anyway I don't get the one just before the exit, with light bridge, angled pannel and cube buttons... Will check the solutions :p

re. room 3: good point.
Hazellius 20 Aug, 2012 @ 4:15am 
I figured out room 1, 3 and 6 by myself. By room 4 and 5 I needed your videos. I tried the way you did room 2 without watching the video, but it didn't work for me. (or at least I thought). By the way, I completed room 3 in a different way that you did it. I just put a portal right under the laser field, and try to jump across.

Here are the "solutions" to each room, in case you can't figure it out but are curious about these.

room 1
room 2
room 3
room 4
room 5
room 6
