Cosmogony is a mod taking place during GLaDOS activation in the Enrichment Center. You are some of the few survivors of the neurotoxin disaster and with some help, you try to find a way out of Aperture. The map pack features custom content, a story deeply immersed in the Portal and Half-Life universe and more.
Great atmosphere
Storywise it might as well not have any and I felt as though i cheesed the puzzles because i could not figure out another way to do them
Still, it was really enjoyable
It's a good packed version, but some texture placement is wonky, and lighting could be redone a bit too. If you want, I can try and fix these problems and PM you the results.
