Indie developer Happy Volcano and publisher Astra Logical have announced the Early Access release date for Modulus. Modulus is an upcoming modular factory simulator, and it arrives in Early Access on PC via Steam on October 22, 2025. Along with the release date, the developers have also released details on its Creator Program, along with its participation in the upcoming Steam Automation Fest with an exclusive demo. Currently, the game has over 100K wishlists, 42,000 demo downloads, and a 96% Very Positive rating on Steam based on previous demos.
The latest trailer for Modulus dives deep into some of the in-game features of the game. Check it out:
Modulus is a relaxing sandbox factory simulator in which you design components that solve different complex problems. Different tools and operators are at your disposal, like Cutters, Stampers, and Assemblers, and you will use them to craft 3D modules that physically form the voxel-art buildings, making your sprawling factories. The game has no combat, timers, or any sort of failure states, giving you freedom to unleash your creativity in any form you like. To give you a small taste of the game, Modulus is taking part in the upcoming Steam Automation Fest before its Early Access release, and it will give you access to a much more advanced build of the game. It will feature:
- New Systems – Paint production via Dye Mixer and Oil Rigs; pigment-based buildings
- Updated Map – Additional oil and polyrock resource zones
- New Models – Harvester Pad with updated footprint
- Tutorial Overhaul – Fully revised to reflect new mechanics and build on feedback
- Operator Improvements – Visual feedback, shortcut keys, and a new Counter operator
- Quality-of-Life Features – Highlight valid resource nodes, delete foliage, rotate operators more easily
- UI Enhancements – Detailed operator panels, speed indicators, updated objective tracking
- Art & Performance Upgrades – Improved animations, foliage, textures, and VFX
- Creative Mode – Fully unlocked sandbox with no resource limits
This is the game’s biggest demo to date, and it offers pretty much everything that the full game will have at its Early Access release. Key features of the upcoming Early Access version of Modulus include:
- Design the Pieces, Not Just the Puzzle – Create modules from raw materials, then use them to construct massive structures that visibly grow from your creations.
- Automate with Purpose – Build to fulfill objectives from the Colony, or forge your own path when a mysterious signal challenges your directive.
- Modular Visual Payoff – Your factories don’t produce abstract data. Every module you make appears in the buildings you construct, block by block.
- Peaceful Production – No combat. No timers. Just deeply satisfying, stress-free automation.
- Creative Mode – Break free from objectives and build voxel wonders with unlimited resources and tools.
- A Meditative Factory Game – Shape beautiful, efficient systems in a game that prizes creativity, experimentation, and flow.
The developer is also excited to announce its very first Creator Program. Titled Happy Volcano Creator Program, Twitch Streamers, YouTubers, TikTokers, writers and community hosts can now apply and get a chance to try out Modulus, You Suck At Parking, The Almost Gone, and all upcoming titles by the developers. Apart from this, the program also offers some exclusive surprises such as:
