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!

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.

Pretty awesome sets of maps so far! I've played part 1&2 and they look and play very well!

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

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.

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: Maybe you should ask Gabe. But for the life of me, I can't find anything in episodes 3 & 4. Apparently there's an easter egg in every map, though.

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...

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. [...]

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. (Like the railing and the turrets on the ground level).
Thanks for playing!!

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.

Part 5

The space under the gel droppers was a little too wide, I accidentally fell in twice and had to restart, as funny as it sounds, it was really frustrating.

Part 6
The solution with the catapult and the fling, eluded me because I thought you were supposed to put a portal on the floor outside the mini test, one over catapult to fling through floor outside, put a portal on the slanted surface, and fall through and out. When I couldn't figure out the next part properly, I did the same thing again and strafed through the air to land on the slanted surface and used the catapult from there. I didn't know that you actually had to fling up to the button and shoot a portal on the slanted surface from inside the test chamber, because I thought that you were supposed to ignore the test and only use the catapult.

Everything else is wonderful and overall one of the best adventure maps out there.
PS Thanks for the response, I think it's great that you're updating it

Great attention to detail with subtle clues, e.g the ladder to draw players eyes up to the portal surface to enter a chamber etc, though for me personally the super strong blue fog was a little odd in places, especially the offices, I always assumed it was blue cause of the supposed ambient light from the panel arms in the huge bts areas, so it makes no sense in an office.

Interesting finale, thought I found it weird I just dropped dead when I portalled to the room the turrets and laser were in enjoyed the ending credits

Overall I feel when you got in to the puzzle maps they were maybe a bit short, but then again im used to working with always putting 2 puzzles in a map or one large one. No major complaints from me

Great job

I don't want to sound like I don't like those maps, I think they are great and with these little bugfixes they'll be perfect. the visuals are awesome, the ending is outstanding, the story is fine and the puzzles were challenging enough, but not too hard, just the way I like them. nice job!

But seriously, this map pack came out of the blue and instantly became one of the best out there, along side Designed for Danger and 12 Angry Tests. My only complaint is that after the exploring is over, and the other story elements, there's not actually that many puzzles. Dreey, I think that if you wanted to update it, adding a few more tests around Part 3 would be a great idea.

If you like adventure, environments, and great Graphics without any real puzzles to speak of - play all the rest of the Levels. For that alone I give this 5 stars. No, 10 stars - the coding is incredible.
