Modulus doesn’t hand you the solutions. You’re given a module to produce, how you produce it is entirely your call. Every production line is a puzzle you design yourself: which operators to use, how to route your belts, how to configure each step in the chain. There’s no single correct answer, but there are trade-offs to every choice you make.

The terrain is part of that challenge. Forget vast open plains, Modulus puts you on sky islands with real spatial constraints. Where you place your production lines matters. Working within the confines of the islands, connecting across the gaps, fitting your factory into the landscape rather than sprawling across it, is all part of the challenge of Modulus.

Modulus is a creative sandbox factory simulation where you don’t just solve problems, you design the components that make up the solution. 

Build and automate elegant production systems using modular engineering tools: cut, paint, stamp, and assemble 3D building blocks called modules.

From logic-driven problem solving to free-form expression, Modulus blends base-building, resource management, and thoughtful strategy in a game that rewards both beauty and efficiency. There’s no single solution, only the system you create.

Programmed by the Colony to supply bots with relentless efficiency, your purpose was clear, until a signal from deep space changes everything.

The Grand Neural Network is calling.

To connect, you must construct massive Neural Monuments: vast, intricate structures that test the limits of your engineering, logic, and scaling automation strategies. Caught between your creators and something far greater, you begin to question your programming and pursue a deeper sense of purpose… one module at a time.

No enemies. No combat. No timers.

Modulus offers a relaxing, low-pressure take on factory automation, where experimentation and optimization thrive. Build at your own pace and enjoy the quiet satisfaction of systems that simply work.

Creative Mode

For those who want to build without constraints, Creative Mode offers full access to tools, paint, expanded module sizes, and unlimited resources. There are no objectives just you and the grid. Design voxel art, test complex layouts, or invent something wild. It’s your sandbox.

Modules aren’t just resources, they’re the building blocks of your factory. Each one you craft becomes a visible part of a structure rising in real time.

The more complex the goal, the more intricate your modules must become, rewarding strategic planning, creativity, and system optimization.

Whether you’re solving intricate logistics puzzles or designing the most aesthetically pleasing factory possible, Modulus is built for creative expression. No two factories will look the same,  your solutions, like your factory, are uniquely yours.
