About this game
The sun never came back
Huta-Grobno, 1983. For months the sky has remained welded shut, a lid of unbroken clouds pressing down upon the city like a suffocating grey grip. No hope, only the slow, deliberate weight of something vast holding its breath.
You were meant to keep the building running
You play as an apartment block caretaker, an electrical engineer finding a fragile comfort in keeping things running smoothly while the city curdles into panic. You piece together what happened through newspapers, uneasy conversations, and a homemade radio tuned to a private frequency of the Church.
The streets belong to other things now
From the black veins of the old mines rises a thick, blood-red ichor the locals whisper of as “Soup.” It climbs through foundations, stains stairwells and pools in places that should not hold liquid. Some things should never be unearthed. Some things were meant to remain buried.
The church has its own plans
As the city slackens into decay, the local ecclesiastical order tightens its unseen grip. They catalogue anomalies with clinical devotion. They perform nocturnal raids without explanation. They do as they please in Huta-Grobno.

A NEW TRAILER HAS CONVERGED
Dzień dobry, dear residents and guests of Huta-Grobno. Something is brewing in Grobnopolis. Something nightmarish, uncaring and existentially dreadful. And while you wait to unveil the game’s secrets, we’ve prepared a new trailer in lieu of Convergence Showcase. Some of you might be visiting Grobnopolis for the first time, so let’s give you a picture of what to expect from “the waning city”. You play as the apartment block caretaker in the mining town of Huta-Grobno. But you shouldn’t confuse the stillness of its streets for an idyllic life – the radio silence hides the talks of horrific accidents all over the city, and the building’s walls are bursting at the seams with the mysteries no ordinary human should perceive. Everyone’s feeling the impending doom, but you are not the one to simply wait for it in a bubble of delusions. For better or worse. Since Grobnopolis: The Last Days is a narrative-heavy game, we wouldn’t want to spoil things that await you in the final version of the game. But if you’d like to take a look at the game already, you can check out the older build on itch.io.Grobnopolis: The Last Days Demo on itch.io That’s all the news we have. For Today at least. Stay on a lookout for the upcoming devlogs and new info about Grobnopolis. Until then, keep your spirits high!BananaDevJeff & CRITICAL REFLEXRead full article on Community Announcements (Mistalleks)AnnouncementsOfficial
CRITICAL REFLEX Sighted In Grobnopolis!
Dzień dobry, dear residents and guests of Huta-Grobno!We have big news: Grobnopolis now officially has a publisher. Who do you ask? None other than CRITICAL REFLEX, the custodians of refreshingly experimental and exquisitely unnerving games. They’re no strangers to poignant chamber stories: be it the cosmic tragedy of Tulpar’s crew in Mouthwashing or the anxiety horror of No, I’m not a Human. And Grobnopolis: The Last Days is an equally slow, oppressive atmospheric horror experience. You are one of many citizens, trapped under a ghastly sky of perpetually shifting clouds. But you’re not the one to simply wait for things to resolve themselves. The suffocating hunger for answers will push you to extreme lengths, leaving you with a simple question – if curiosity killed the cat, did it at least die satisfied knowing the secret? Grobnopolis is also one of three brand new additions to the CRITICAL REFLEX's catalogue of tenebrous experiences. SOS Recordings — a lone mountain in northern Japan. Two hikers rescued alive from its silent maw. In their wake, a perfect SOS made of tree trunks, built years before anyone was lost. Based on a real unsolved case. The recordings are waiting. Cucina Stellata — a short psychological horror where gastronomy, ritual, and cosmic appetite share the same table. Rich in historical atmosphere and literary voice, Cucina Stellata is a one-sitting descent into exquisite taste and devouring craving that knows no end. Stay tuned to our frequency for more news and devlogs to come. And keep your spirits high! BananaDevJeff & CRITICAL REFLEXRead full article on Community Announcements (Mistalleks)
