- UPDATE TIME | Mod Support is here! - 25 June 2026
You asked for it and we’re delivering; Modulus now has official mod support, and we can't wait to see what you build. Seeing as this is such a significant update we wanted to do a proper post rather than just patch notes. So, let's dive in.FOR PLAYERS Subscribing to mods is simple. Head to the Modulus Steam Workshop, find something you like, and hit Subscribe. Mods load automatically when you start the game, no fiddling required. You'll find a new Mods tab in Settings (also accessible from the Main Menu and Pause Menu) where you can see everything you have installed and toggle mods on or off.Modulus Workshop: https://steamcommunity.com/app/2779120/workshop/ Also it is worth flagging the following:• Steam achievements won't unlock while any mod is active• Any save file you play with mods enabled will be permanently marked as Modded, even after uninstalling mods• If something looks off, t…
- Modulus Academy | Episode 7: Expert Production Layouts - 4 June 2026
Hey Module Makers!David's back with what might be the most mind-expanding episode of the Academy yet. Episode 7 is all about expert-level module production, a fundamentally different way of thinking about how you build. If you've ever felt like your factories are getting the job done but taking up way more space than they should, this one is for you. If you’ve ever seen one of Jarvs’ streams then you know what we’re talking about (hehehe). The core principle underpins everything in this episode: the more voxels you can manipulate in one operator, the fewer operators you need. The Standard Approach | Efficient, But SpaciousDavid starts by showing how most players tackle module production, using a module for the Lumite Reactor as his example. The typical approach: take a full belt of cubes, assemble to a big block, cut it into the smaller pieces that make up the module, paint and stamp th…
- MASSIVE UPDATE TIME - 15 May 2026
Hey Module Makers,Patch 5 is here and we want to give you a proper look at what's included, because this one is a big deal. We've been listening closely to your feedback since launch, in reviews, on Discord, in the forums, and beyond, and a lot of what's in this patch is a direct response to what you've been telling us. Let's get into it.The Stamper Just Got a Whole Lot SmarterThe Stamper changes are probably our favourite part of this patch, so let's start here.First up: you can now choose which module exits which side of the Stamper. If you've ever found yourself fighting your layout because the Stamper was outputting things the wrong way around, that frustration is gone. Route your resources the way your factory actually needs them. Second: we've added a scrap behaviour toggle. This one has an interesting backstory. Back in early playtesting, we made a deliberate call to keep the Sta…
- Thank You, Module Makers - 11 May 2026
It's been a little over a month since Modulus launched, and we wanted to take a moment to say something simple: thank you.Watching this community come to life has been one of the best parts of making this game. The screenshots, the layouts, the Discord discussions about the most efficient way to route a belt, the community mods, and so much more! The whole team has been following along and loving every second of it. Your Streams and VideosWe put a lot of love into Modulus. Seeing you love it back means everything to us. So, we collected a bunch of our favourite clips of your videos and streams to celebrate an amazing first month of Modulus: Your ScreenshotsWe asked ourselves what better way to celebrate than to let your work do the talking. Here are some of our favourite screenshots from the past month, your factories, your creativity, your chaos: This is just the beginning. We're conti…

- Modulus Academy | Episode 6 Freighters - 29 April 2026
Hey Module Makers!David's back in the Academy, and this episode is a big one. Freighters are something you'll encounter a bit later in the game, but once your factory starts spanning multiple islands, they become essential for clean, scalable logistics. Here's everything you need to know. The Basics | Setting Up Your First FreighterThe core idea behind freighters is simple: instead of running skylines everywhere, you use freight hubs to centralise a resource and distribute it cleanly across your factory.When placing a freight hub, pay close attention to which input dock you're delivering to. The freighter has four cargo containers, each corresponding to a dock number, so if your resource arrives at dock one, the freighter will load it into cargo slot one. Slots two, three, and four won't pick up anything unless something is connected to those docks.A habit worth building early: always n…
- Patch 1.0.4 - 27 April 2026

- Modulus Academy | Episodes 4 & 5 - 21 April 2026
Hey Module Makers!David's been busy in the Academy, and we've got two more episodes worth of tips to catch you up on. Whether you missed them or just want a written reference to come back to, here's the full breakdown of what episodes 4 and 5 covered.Episode 4 | Debugging with the Efficiency View Episode 4 is all about one of the most powerful tools in Modulus that players often underuse: the Efficiency View.Unlocked through the tech tree, the Efficiency View is accessed by pressing H. It recolours every operator in your factory to reflect its current efficiency, green means running at full capacity, yellow means underperforming, and red means something is seriously wrong. The goal is simple: get everything green. (Side note if you look closely everything also has a pattern on displaying the corresponding number in the key. This is so that those with red/green colour blindness can still…
- Demo Update 20th April 2026 - 20 April 2026
A note before we get into it We know many of you have been waiting on fixes for the demo for a while. As a small team, getting the full game launch out the door meant the demo had to take a back seat temporarily, and we really appreciate your patience with that. This update is a big one, and we hope it makes the demo experience significantly smoother for anyone jumping in for the first time or returning to check it out.Thank you.Now, here's what's been fixed:GameplayFixed an issue where loading a fully completed demo save would skip unlock monument objectives and jump straight to "Complete all monuments"Fixed a softlock where the player was unable to finish the demo after delivering the AndroidFixed an issue where buildings would consume datashards for auto-upgrades while the next floor upgrade was still lockedFixed an issue where the player could place factory assets mid-airFixed an is…
- Free Build Map is Live! - 16 April 2026
It's here, Module Makers, The Free Build Map is now available in Modulus! When we previewed this last week the response blew us away, and we can't wait to see what you build with a bit more room to breathe. From today, when you start a new save you'll be able to choose between the Classic Map and the Free Build Map; more space, logical Polyrock layouts, and no terrain constraints getting in the way of your factory vision.The Classic Map isn't going anywhere. Two ways to play, one game. Pick your challenge. We have also tweaked the tutorial to include the fact that you can place belts through miners, as many players reported not realising this for several hours. Additionally, the update includes the following fix: Fixed softlock when trying to link harvester pad drone to a building Also live today: Steam Trading Cards! Collect, trade, and show off your love for Modulus. Cards drop as you…
- Free Build Map Coming to Modulus - 10 April 2026
Hey Modulue Makers First up WOW. Thank you from the bottom of our hearts for such an incredible launch week. Your excitement and enthusiasm around the game means more to us than we can put into words. Seeing everyone sharing screenshots, giving each other advice on optimal layouts, and just generally being as excited about the game as we are, has been absolutely awesome. We have been listening to feedback and monitoring the Feature Upvote Board for your most requested suggestions and have begun putting a plan together to decide what's next for Modulus. There has been one particular suggestion that has come up a fair few times in reviews and forum posts, and that is to give players a way to build without the terrain constraints present in the campaign. Whilst the puzzle aspect of designing a factory around these constraints is intended, and is the recommended way to play Modulus, we do g…

- Introducing Modulus Academy - 6 April 2026
Hey Module Makers!If you've been following along with our Modulus Academy video series, you'll know that Creative Director David has been dropping some seriously useful tips for getting the most out of your factory. Whether you missed an episode or just want a handy written reference, here's a rundown of everything covered so far. Episode 1 | Operator Efficiency The first episode laid the groundwork with one of the most fundamental concepts in Modulus: identifying and eliminating bottlenecks.David walked through a basic production line, four miners feeding a furnace, a cutter, and an assembler, to demonstrate a common pitfall. The miners produce 60 polyrock per minute, the furnace processes that into 15 cubes, the cutter slices each cube into 4 pieces (60 pieces per minute total), and it all looks great... until it hits the assembler. The assembler can only take in 15 pieces per minute…
