About 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.

Start Simple, Grow Smart

Begin with basic resources and learn the core systems. As your production needs scale, unlock new mechanics, tools, and challenges that deepen your understanding of logic, optimization, and modular design mastery.

How much does Modulus for PC cost right now?

Modulus for PC starts at €15.57 at Kinguin, a Steam key, which is 36% under the €24.50 it costs on the official store.

That €15.57 already includes the AUGGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Just 3 stores stock it, 4 offers in all, so there is little here to push the price either way.

It is €0.82 away from its all-time low (€14.75, back in March 2026).

Is it worth buying the Steam Key for Modulus now or waiting?

That €15.57 key has never had a real discount yet.

  • The Steam Key has been on sale for 10 months and its biggest drop has been 14%.
  • Only 3 stores sell the Steam Key, and with that little competition the price barely moves.
  • Not counting today, the Steam Key was at this price or lower on 108 days out of the 133 days on record: this is basically what it always costs.
If you are in no rush, it is worth waiting for a sale. We have seen it at €14.75 and we will tell you the day it drops.

Worked out from 378 daily records of the Steam Key for Modulus across 3 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Can you activate Modulus in US?

3 of the 4 offers work on US — the Global ones plus the ones issued for your own region.


Most common FAQs when buying Modulus for PC in digital format:

It is a key that will allow you to download the game Modulus on your PC from official download platforms.
As of 23/08/2026, in United States, the best price we have found in our selection of online stores that include the key for Modulus on PC is €15.57.
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Modulus to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Modulus, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.
