[SP] The Cosmogony Map Pack
Hello everyone and happy second workshop anniversary! Anyways, it's been a loong time. I've been working on these maps for quite a while now. So without further ado: it was nice catching up, let's get to business.
Cosmogony is a 6 part map pack set during GLaDOS activation in the Enrichment Center, with custom story and visuals! I tried to follow the Portal story and capture the same atmosphere, so I hope I got it right. After a year and a half of developing and a lot of hard work, It's finally out. I hope you have as much fun playing it as we had developing it.
ALL MAPS ARE NOW AVAILABLE. Thanks for playing!
All feedback is appreciated. Please consider recording a playthrough. It helps a lot and it can turn into an official walkthrough (as I'm in need of one) and be featured in the maps pages!
On a side note, there are A LOT of easter eggs. Seriously. Every map has at least one easter egg. If you find one or more of them, be sure to post it here!
Enough chitchatting! It's you and me against the world, son! Now let's solve this thing!
So, i now played part 1 and part 2.
All what i can say is awesome. I love the detailing, the exploring, the whole environment,
Really a masterpiece, this should be a mod, and not the twtm mod
Pretty awesome sets of maps so far! I've played part 1&2 and they look and play very well!
here's my playthrough:

Can't wait for part 3-6
[...]Thank you for the feedback! Parts 3 and 4 are now up.
Thanks for reporting the easter egg too! It was one of the first easter eggs to be put in the map
The intro was one of the stuff that most changed in the map. First, waking up in the middle of the neurotoxin disaster and just closing your office door to survive felt a bit unrealistic. So I had an idea to make a cinematic intro. Going thru the vents of Aperture and watching GLaDOS being powered up. So as Portal 2 hates .ani files I couldn't place any human NPCs in the intro, and that was disappointing. Just hearing people scream and not seeing them was scary I'll admit, but not as I expected. So there was a long time without intro and with no ideas at all. I was just playing with hammer to see what I could come up with. I didn't want to just throw away all the content I created so I recycled some stuff. Including content from my previous maps, if you played them, you'll notice. So I think I can say my previous maps were just experiments.

Can't wait for part 3-6
Thanks for the video Lp! It helps a lot to see how test subjects... I mean, players behave while playing the map. You're not the only one who don't know how to say the name of the map:
"[koz-mog-uh-nee]" I'll let you search for the definition 
Played through 1 & 2 - outstanding, will look for 3/4 now.... Beautiful maps...
Finished 3&4 - excellent again - very nice puzzle in 4...
Incredible, Amazing, Well Done! I left most of my opinions on the collection page on the workshop. But on this forum, I'd like to say a few things about my experience with the gameplay, and some constructive criticism from what I can discern. I'd like to start out by saying that I agree with pretty much everything in LP's video, especially about the amount of doors, so I won't repeat those (anymore), but here's some additional feedback. To anyone who did not make Cosmogony, and didn't play it, stop reading, and go away.
Part 1
-The railings in the first, main room, are a little too short, leading you to think you can jump over them, but you can't. Whereas in the stairwell, with the same railing height, you can.
-I thought it took too long for Wheatley to make his debut appearance.
Part 2
-I also thought the wait time was too long when Wheatley was talking, cause I ran out of things to do and look at, by the time he was halfway done talking.
-In the turret part, it is was a little difficult to realize that you could pick up the turrets inside the containers. And I kept trying to move the light bridge wall really fast to get up the elevator. I think you should make it a little more obvious or change the puzzle around so as not to mislead the player into a wrong solution and think that you have to be an expert player to do it.
-I don't think you should disable the portal gun for the whole office part after the lift, but rather, separate the rooms and decrease the amount of portal surfaces where you don't want them or something. Or whatever.
Part 3
-At the place where the ladder is, there should be more focus on where to place the portal with lights or a cable, I don't know. Just more focus, because it has a gate over it, and at first glance looks like part of the wall.
-Sometimes when you launch the cube at the button the correct way, it doesn't land on the button.
Part 4
-This is the test where I realized that the lighting felt a little destructive to the puzzle-solving process, and a little monotone(ous). I think for this room, a bright or a little warmness to the light would make the player feel more comfortable to try new methods of solving. The general color for the map pack works well for gloomy parts, but in this room it felt a little discomforting. I would like to see more variation throughout the map in terms of light color, just to add to the beauty it already has.
That's all. Again really really enjoyed, best map pack in a long long while, nicely done.
Awesome! When are 5 and 6 comming out?
One of the best Portal 2 map packs on the workshop, in my opinion. Most of my praise for your work has already been stated here, though, so I'll save you some reading.
I found some easter eggs in episodes 1 & 2. I must say they are very cleverly hidden and interesting, though I don't want to spoil them for others so I'll just say this:
For some reason, that "help me" on the computer monitor really gave me chills. It almost seemed like...
there was someone in there with me...
Thanks for the feedback. I'm aware of some things you reported, some of them will change in the next update, others I've tried to solve already but couldn't 
and some I'll leave it.
Thanks for playing!!
Today, hopefully.

Thanks for reporting! There's still some more easter eggs to be found.
Episodes 3 and 4 have only one or two easter eggs. However, episode 1 and 2 have a lot yet to be discovered.
