Modulus Demo Lands on Steam with a Fresh Spin on Factory Automation

Modulus, a creative twist on factory automation, launches its first demo on Steam, courtesy of developer Happy Volcano and publisher Astra Logical. Players can cut, color, stamp, and assemble modular components to build unique fully functioning factories from the ground up with a creative, hands-on approach.

Build Your Way: No Rules, Just Modules

In Modulus, factory-building bends to your imagination. There are no fixed recipes—every structure comes from the modules you produce, offering a personal spin on automation. The demo lets you watch creations take shape block by block in real time, from simple Grey and Blue buildings to complex designs. A quick tutorial welcomes newcomers, while Zen Mode unlocks a sandbox for freeform fun. Catch the vibe in the demo trailer.

Chill Vibes and Big Factories

No rush, no stress, no timers, no enemies. Kick back with your modules and a sprawling factory dreamscape. The demo’s Zen Mode ditches objectives entirely, letting players build purely for the joy of it. Experiment with operators and scale up to meet The Grand Neural Network’s demands, all at your own pace.
