>>2394072well what i envisioned was the player would take the role of a city worker tasked to do some maintenance work down there and because of a (unhealthy fast food) poop gas build-up they'd pass out and start hallucinating, point at which the game turns into the sewer equivalent of a dungeon crawler where they must fight all sort of weird monsters evolved out of things people flush or pee like from birth control and pesticides to microplastics in order to survive and wake up and then tongue-in-cheek conclude that it was all made up and not true in the slightest ha-ha
now i can imagine some people pooping in the storm drains or it getting there by rain but not in such an amount to pose a threat, nor all those modern nasties being washed off down there
i guess i could spin it and make the gas from something else like animal corpses decomposing or something fermenting or whatevee but i can't think of a basis for the weird mutated creatures, and that was more like the moral of the story, you know?
