📐 Inside the Systems | Interview with Thomas Preudhomme[/h2][p]
![]()
[/p][p]To celebrate this update, last week we caught up with technical artist and game designer
Thomas Preudhomme to talk about how Modulus was designed from the ground up as a system-led experience.[/p][p]🎥
Watch the full interview on YouTube → 📖
Or read the full interview on Steam →[/p][p]Here’s a small excerpt from the conversation:
[/p][h3]
🧱 The Building Blocks of Intelligence[/h3][p]
Jarvs: What was the process for designing individual operators like the Cutter, Stamper and Assembler?[/p][p]
Thomas:Yeah, the process was quite a lot to be fair. I think it's very interesting because the Cutter, Assembler, and Stamper are kind of the basic three operators that do everything in the game. You can do every module with those, which is interesting, but also very hard to balance.[/p][p]If you look at the Assembler, for example, which lets you drag and drop stuff, then you can rotate them around and basically you can do kind of anything. It’s nice because you literally drag and drop. But before there were arrows you had to click, and that kind of thing can be super wonky, but also much more precise.
When you have holes to cut out, it starts to be hard to manage. It’s a fine line we’re still making it more user-friendly. But whilst keeping the kind of playful aspect of just dragging stuff together.[/p][p]
Jarvs:[/p][p]Yeah, I think that's one thing that we need to stress is that this is just a demo and things will change by the time the game fully comes out and they're changing all the time, mostly based on your guys' feedback. One of the things people were saying was that when they first tried the demo, moving things around in there wasn't quite as intuitive as they wanted it to be.[/p][p]And that's already improved loads. And so we're listening and we are constantly iterating.[/p][p]
Thomas:[/p][p]Also, you previously had a thing called the
Rotator, which we completely removed, because now you rotate stuff inside these operators, and that wasn't the case before. It made everything way harder. I think that's also something we noticed players do, they just hated it. So we just completely removed it, and things work fine this way…[/p][p]
\[Full answer continues in the full interview →][/p][h3]
🔮 Looking Ahead[/h3][p]
Thomas:I think at least for me, the most interesting thing coming is a deeper level of logistics. Such as the
Sorter, which is an operator that will allow you to sort modules based on what they are… That makes it so that you can basically add some logic to the game.[/p][p]We’re also introducing a
Tech Tree and a new resource:
Data Shards. These will allow you to unlock new upgrades like drones, extra islands, faster operators, really cool stuff that lets players build toward their own goals.
There's a whole bunch of upgrades. So, new operators, a
Warehouse that just stores items, and just a lot of different things that you can unlock through the tree.[/p][p]So you're going to look at it and be like, oh, I really want this upgrade, let me just work for it.[/p][p]So I think that's going to be a pretty big change in how we perceive the game. Because currently it's just the game telling you, okay, make bots for me and you’re like sure. But that doesn't give you anything, right?
[/p][p]
Jarvs:[/p][p]It also adds to that level of satisfaction as well, as you're actually making stuff that benefits you as a player. And I think, again, that that adds an extra step of like, okay, I'm doing this for myself, which is really rewarding. I can see progress happening in this
Tech Tree and I'm working towards a specific thing.[/p][p]That's one of the comments we had about the original version of the demo; "Why am I doing this? What is the point in making the bots?". Essentially the demo is here to teach you what the core systems of the game are, and how you play
Modulus on a base level.[/p][p]Moving on from that, you're going to unlock deeper levels. You're going to unlock the
Tech Tree you're going to unlock as you said, different operators. Then that's where the
narrative comes into play, which will actually start making sense of why you're doing the things you're doing.[/p][p]
Thomas:[/p][p]Yeah, exactly. We kind of tell you in the demo, that we say you’re supplying
the Colony. We don't tell you what
the Colony is, but yeah, we kind of hint towards the narrative side of things that you will later in the game also deliver robots.[/p][p]But it’s important to note that you will have both the narrative goals and your own goals….[/p][p]

Lore Update: The Grand Neural Network[/h2][p]
![]()
[/p][p]Alongside the gameplay overhaul, we’ve also updated the
narrative foundations of Modulus.[/p][p]You are an AI built by the
Colony, deployed to a floating island factory complex above the planet’s surface. Your mission: build an endless stream of Bots. That was your sole directive… until something changed.[/p][p]A mysterious signal begins to call to you, from beyond the stars.[/p][p]The
Grand Neural Network is calling you! It offers a new purpose: the construction of vast
Neural Monuments to establish a connection unlike any before.
Torn between your creators and this higher calling, you must choose your path. Will you obey… or evolve?

🎙️ Get to Know Us: Mick & Antoine Talk Inspiration, Genres, and Dream Mechanics
![]()
[/h2][p]In the second episode of our
Get to Know Us series, we sat down with
Lead Developer Mick Rüdiger and
Art Director Antoine Lendrevie to dig into their personal inspirations, design instincts, and dream game ideas. If you’ve ever wondered what games shaped Modulus behind the scenes, or what our devs would love to build next, this is the conversation for you.[/p][p]Here are a few highlights from our chat:[/p][p][/p][p]
🎮 What games inspire you most as a game maker? Antoine: I love world-building and atmosphere. Games like Ico, Shadow of the Colossus, Journey, Inside… those are my top inspirations. Inside, especially, I think it’s perfect. The lighting, music, animations… it’s incredibly polished for such a small team. It’s what I aspire to.[/p][p]
Mick: I agree, Inside is incredible. For me, I’ve always been drawn to games where you “own” the space, movement-focused stuff. I’ve played an insane amount of Minecraft, fighting games, FPS shooters. I didn’t grow up playing a lot of narrative games. I like games where your actions define everything.[/p][p]
[/p][p]
🕹️ What’s your favorite genre to play… and make? Antoine: Adventure games, easily. I love exploring new worlds. The first ten hours of Breath of the Wild were probably the best gaming experience of my life. But as a developer? I’d love to make an RTS one day. StarCraft II is the game I’ve spent the most hours in. Building worlds and units would be a dream.[/p][p]
Mick: Let’s make one! I played a ton of Warcraft III. But my genre of choice is fighting games. Street Fighter IV is probably my most-played game. I love that they’re compact but expressive, two players, same screen, but you can tell who’s behind the controls just by how they move.[/p][p]
[/p][p]
🔧 What’s a mechanic you’d love to see more games use? Antoine: Destructible environments, with purpose. Too often they’re just visual flair. I’d love to see destruction that impacts level design or strategy, like in Stalingrad where cover and visibility change mid-battle. Teardown is cool, but I want to see destruction tied to gameplay more deeply.[/p][p]
Also: stealth. It hasn’t really evolved in 20 years. Chaos Theory’s spy-vs-mercs mode was amazing, with real use of lighting and line of sight. I want to see that again, but modernised,dynamic shadows, true hide-and-seek tension.[/p][p]
Mick: Agree completely. We played a lot of GTFO and it uses lighting and sound in really stressful ways. But if I had to pick one mechanic to bring back, it’s strafe jumping. I played so much Enemy Territory and Quake III, just practicing movement maps. That feeling of control over momentum, it’s still unmatched.[/p][p]🧠 The full interview will be available on
YouTube soon, and you’ll be seeing more of Mick and Antoine in upcoming behind-the-scenes content. Have a question you’d like us to ask in the next episode? Drop it in Discord or the Steam Discussions![/p][p]
