Marek’s Dev Diary: November 20, 2025

What is this

Every Thursday, I will share a dev diary about what we’ve been working on over the past few weeks. I’ll focus on the interesting challenges and solutions that I encountered. I won’t be able to cover everything, but I’ll share what caught my interest.

Why am I doing it

I want to bring our community along on this journey, and I simply love writing about things I’m passionate about! This is my unfiltered dev journal, so please keep in mind that what I write here are my thoughts and will be outdated by the time you read this, as so many things change quickly. Any plans I mention aren’t set in stone and everything is subject to change. Also, if you don’t like spoilers, then don’t read this.

 

 

Space Engineers 1

We will be launching Space Engineers: Core Systems Update & Pack this Monday, November 24

The Core Systems Update will bring a wide range of quality of life improvements, gameplay refinements, and important bug fixes. This update focuses on polishing the foundation of Space Engineers – from new set value actions for multiple blocks, to joystick support, and streamlined interactions for planting and harvesting your Farm Plots.

The previews by our amazing community creators are already in full swing and more videos are revealed every day!

 

Space Engineers 2

And we will be launching Space Engineers 2: VS2 – Planets & Survival Foundations a week after SE1, on Monday, December 1

You will soon leave the training grounds of Concordia Research Facility behind you – now it’s time to travel into the Almagest system. A new frontier will stand stretches before you, vast and unexplored, waiting for the first Engineers to shape it.

I have made an overview of all the main VS2 features in my previous blog post, along with an updated roadmap.

Join the countdown with more Space Engineers 2 VS2 Community previews!

 

Space Engineers 2 Music Competition

The deadline for your submissions is coming close – if you want to compete, now is the last opportunity to send your music tracks.

Our music competitions are one of my favorite events. Music and sound have always been a really important part of Space Engineers for me. 

Last year I had an amazing moment at Smecky Studios in Prague, sitting with the whole orchestra and our composer Karel Antonin, listening to the Space Engineers 2 soundtrack being played live. 

Hearing it take shape right in front of me was unforgettable.

 

Question to you: Are you ready?

 

Share your thoughts in the comments below – I read them all, and they’re one of my favorite parts of making our games.

  • 1) Any plans yet for SE2 regarding grid and subgrid? Is the general idea to keep SE1 behavior, or is there at least a possibility of reconsidering the approach for SE2, eg make subgrid components (like thrusters, wheels) controllable from main grid “natively”?
    1a) Any plans for configuring such movement components to the main cockpit movement inputs? Eg. specially named groups of blocks?
    2) Roughly where in the SE2 roadmap is controller support? Compared to everything else I realize it’s not essential, but personally I’m wishing for it sooner than later, because controller has become my main input.

  • To what extent will VS2.2 have weapons? Will it be simple gatlings and rockets or will we get larger cannons in automated turrets? 

  • Wheels seem to be suspiciously absent from the roadmap. Should we assume they are part of subgrids in 2.2?

    Rovers are very iconic and fun, and core to the gameplay for many people. I would love for them to just arrive in 2.2 so planets can be thoroughly enjoyed.

    • On a different post (I believe it was one of the ones on steam) they did list wheels as comming sometime after vertical slice 2. I also agree that wheels are a important part of planitery survival and highly encourage Keen to have wheels be apart of one of the first updates after VS2

  • 10, 9, 8, 7, 6, 5, 4, 3, 2, 1… Yes, I’m ready, all you have to do is say “Ignition”🚀

    I am SO READY! My RX 7800 XT I can only hope is because I’m playing on absolute max graphics lol. I can’t wait!

  • In Space engineers 2 can we get a block with an interface similar to the “controller” block in Scrap Mechanic? There just does not seem to currently be an intuitive way to have a sequence of actions performed when a block is toggled and them have those actions perform in reverse when the block is toggled again. (One use case I have run into is making a belly side ship elevator for loading rovers and what not, and that elevator also has a hatch that closes beneath when it is stowed.) The problem I run into is I can have timers make the sequence happen one direction (the custom door hinges open and then the pistons extend), but when I press the button again, the doors try to close before the pistons retract.

Biography

I have always been driven by the need to create — games, AI agents, ideas. That’s why I started Keen Software House: to create games that only existed in my head. After Space Engineers took off, I founded GoodAI to develop AGI, to help humanity and understand the universe.

These days I’m focused on Space Engineers 2, the VRAGE3 engine, AI People, and autonomous agents in general — powering NPCs in our games, or swarms of autonomous and intelligent drones.

It’s all part of my long-term plan: to make civilization stronger, greater, and more resilient.

Our home base is a 17th-century Oranžérie in Prague — but we’re a remote-first, global team of 100+ programmers, artists, designers, and engineers.

I am proudly European , and in the last few years, I’ve come to love South Africa and its people.
