You are the only human stranded on a planet-sized junkyard where the universe dumps its discarded machines.

Robots survive here on scrap and recycled energy. They do not trust humans. To stay alive, you must hide in plain sight behind a mechanical helmet and build a life among them.

But survival is only the beginning.

Play Solo or in Co-op

Silicone Heart can be played solo or with up to four players in a shared world. You build a single farm together, manage the same resources, and contribute to one progression system. Everything you grow, automate, and repair benefits the entire group. Co-op does not change the core mechanics. It simply allows you to experience them side by side.

Working together naturally creates different playstyles. One player may focus on farming, another on automation, while others explore or restore damaged machines. You can switch roles at any time or split up to cover more ground. Whether you stay together or branch out, every action contributes to a world that evolves through your combined effort.

Build a Biomechanical Farm From Scrap

Turn wreckage into opportunity.

Salvage parts from broken machines and transform rusted ground into a self-sustaining cyber farm. Grow hybrid biomechanical crops designed for this world. Your harvest is not food. It is fuel. Robots convert your crops into energy, the planet’s primary currency.

Energy becomes power.
Power becomes progress.

Expand your farm, unlock advanced systems, and build production chains powered by reclaimed technology.

Automate Everything

As your farm grows, so does your ambition.

Deploy drones, printers, and programmable robots to automate planting, harvesting, processing, and maintenance. Build efficient systems that operate around the clock while you focus on exploration, experimentation, and expansion.

Gather resources

Forge your path on the planet. Venture deeper and deeper for valuable resources essential for survival. Create tools to aid your journey: from a pickaxe, fishing rod, and shovel to an exoskeleton, laser, and rockets. Upgrade your equipment and arsenal with advanced tools: assemble helpers from parts to automate resource collection, garden care, animal tending, and other tasks. Level up your technology and unlock new items to improve your experience on this harsh planet.

Repair the Discarded

Beyond the structured robot city lies a harsher reality.

Many machines outside the city are damaged, dismantled, or abandoned after years of exploitation and neglect. By salvaging parts and restoring broken robots, you bring forgotten machines back online. Each repair strengthens the world around you and opens new possibilities.

Over time, your actions begin to reshape the mechanical society itself. Change does not happen instantly. It happens gradually, through care, persistence, and steady improvement.

A Cozy Story with a Satirical Edge

Inside the city, robots follow rigid routines modeled after human systems. They complain about inefficiency and leadership while continuing to repeat the same patterns.

As the only human living among them, you witness a society shaped by the very structures humanity once built. The more you repair and integrate into this world, the more its inhabitants begin to feel less like machines and more like individuals shaped by circumstance.

Silicone Heart blends cozy farming and light automation with quiet satire and gradual world evolution. It is a story about discarded things, second chances, and the power of steady care in a world built from what others threw away.
