When the world froze, humanity built its last hope — a colossal mobile nuclear facility crawling across the endless ice.
You are the engineer commanding this reactor on treads. Manage nuclear physics, control heat, automate production, and survive the cold wastelands to rescue what’s left of humankind.
Each decision defines survival. Will you optimize for stability or push the limits of nuclear power?
In Nuclear Crawler, every system you build is a story of control, failure, and human resilience.

In Nuclear Crawler, every system you build is a story of control, failure, and human resilience.
Beneath the ice, forgotten technologies lie dormant — remnants of the old world, buried under centuries of frost.
To survive, you must awaken them.
Expand your crawler, restore ancient reactors, and harvest the planet’s last resources.
Every discovery brings progress, but also danger. The deeper you dig, the closer you get to the core… and to whatever still breathes beneath it.
Build, Automate, Survive
Construct a modular nuclear base mounted on a massive ice crawler.
Balance energy output, temperature, and mobility to keep the system stable.
Expand your crawler with research labs, housing modules, and reactors.
Survive storms, radiation, and mechanical failures while exploring a dead planet.
Explore the Frozen Unknown
Authentic fission physics with rod control, pressure, and heat exchange systems.
Steam circuits, turbines, and condensers with real operational parameters.
Complex automation networks for energy and resource management.
Avoid overheating — or your entire crawler becomes a glowing crater.
Add Nuclear Crawler to your Steam Wishlist and prepare to master the frozen frontier.
