Possible One: Lunar Industries is now in Early Access on Steam. We’ve been waiting for this one — we got hands-on time with Upstairs Games’ lunar colony management sim at Gamescom Germany last August, and the promise was real. The game challenges you to transform a fragile lunar outpost into humanity’s first self-sustaining industrial operation, built on real-world scientific principles and the brutal, unforgiving realities of surviving on the Moon. Radiation, supply chain fragility, infrastructure failure, and limited resources are all working against you. Your job is to turn a foothold into a future.
Upstairs Games is a small studio founded in 2021 by a group of friends united around their love of grounded industrial space settings. Possible One is their defining project — and from our time with it at Gamescom, one of the more considered and authentic takes on lunar colonisation in the management sim genre.
What You’re Building
You start with a fragile outpost and a mandate. Construct habitats, manage oxygen supply, regulate radiation exposure, oversee food production, and maintain the critical infrastructure that keeps your colonists alive long enough to do the actual work. Survival is only the first problem. The second problem is scaling that survival into a functioning economy — extracting lunar resources, refining valuable materials, and expanding industrial operations across the surface to build something that doesn’t just survive but generates value.
The game is grounded in real-world science throughout — the technologies, the constraints, and the challenges are inspired by actual proposals for lunar colonisation rather than science fiction shortcuts. That grounding is what made the Gamescom build feel different from the average colony sim: the problems are specific and the solutions require the same kind of engineering thinking that the actual Moon presents.
From Gamescom to Early Access — We Were There
When we checked out Possible One at Gamescom last August, the Upstairs Games team was running a hands-on booth with early build access. The colony systems and the moment-to-moment decision-making were already compelling at that stage — the balance between survival management and industrial ambition was clear, and the real-science grounding gave every challenge genuine weight. It’s been a long road from that build to today’s Early Access launch, and we’re glad it’s here.
