- Dev Update - 26 August 2026
Hello everyone!I know it has been a long time since the last update, so I want to be clear: Steel Artery has not been abandoned, and work on the game continues.Unfortunately, the game’s launch was weaker than expected, so I cannot afford to work on it full-time. I need to support my family, and I currently work on Steel Artery in my limited spare time.As I mentioned earlier, fixing bugs and continuing to develop the game requires a substantial overhaul of the simulation engine, which starts to break down once colonies reach a certain size. This is a fundamental issue, and until I solve it, I cant release a series of small updates just to reassure players that I’m still aboard and moving forward.I also no longer want to make promises about specific dates or the contents of future updates. My own promises have worked against me several times when plans changed or the work took longer than…
- What Stations Will Look Like in the Game - 6 June 2026
Hello everyone!Work on optimization is in full swing. I significantly underestimated the complexity of moving parts of the game to C++, and I'm still working on it. However, I hope to release an optimization patch in June and then move on to other tasks.I'd like to share a station mockup. It's still a work in progress, but it should already give you a good idea of how stations will look in the game.By the way, what new station-related gameplay features would you like to see? (Besides trading) Maybe someone has an interesting idea that could add more depth to the gameplay. Hope everyone is having a great day! ☀️
- I'm Still Working on Optimization and Logistics - 28 May 2026
Hello everyone!First of all, sorry — the next patch is taking a little longer than expected.Initially, I wanted to quickly improve performance by moving some calculations to native C++ and release the patch this week, but.. it turns out that doesn't really help, because the bottleneck isn't the calculations themselves — it's the way data is stored and prepared.Because of that, I've decided to resort to some old-school programming techniques (various hacks, such as packing data into extremely dense index structures instead of traditional objects), and that will take some additional time.I also want to apologize for not fixing everything that was supposed to be fixed in the previous patch (although at least some issues were resolved).Right now, my priority is increasing performance enough that even weaker machines can handle 1000+ creatures in real time. That's why I'm focusing on optimiz…
- Fixed. Changes in 1.0.6 and a few words about what’s next - 23 May 2026
Wow… seriously, wow. I’m genuinely overwhelmed by the amount of support and warmth in your messages. It became the fuel I needed to continue this difficult journey (instead of coal and dirty water ^_^).I think I’ve fixed everything that was broken — and even improved a few things. I didn’t have enough time to test all of it super thoroughly, so I still assume there may be issues left. The current update should be compatible with old saves, though as always, something may still go wrong — and if it does, I’ll definitely do my best to fix it once you let me know.In the comments, please share your impressions of the current build — does it feel better now?And if you’re too lazy to read the changelog — don’t leave just yet, because at the end I also talk a bit about what’s coming next.Changelog 1.0.6:Fixed logistics and made it smarter — smarter task “bundles” are now used. For example, a c…
- Train crashed into the wall - 18 May 2026
Hello everyone! Well… this hurt a lot. The game launched with good reviews, and within just a couple of days dropped to 62% positive. Honestly, over these last few days I went through every stage possible — from arguing with players (“my game is good, you just didn’t understand it”) to fully agreeing with the feedback. If a product fails to justify itself on its own, then that’s reality.I read everything players wrote — every review and every discussion thread. I replied wherever I felt it was appropriate. Sometimes I argued, sometimes I acknowledged problems, sometimes I gave advice and promised fixes. My tone changed over time because, as I kept reading more and more feedback, I gradually came back to my senses and started recognizing where the criticism was fair. So I apologize for the moments where I was too harsh.Right now, I’m fully focused and ready to continue working on the gam…
- Steampunk colony sim Steel Artery is here, and it's "emergent chaos" aboard a giant train - 16 May 2026
Steelpolis is more than just a train - it's the last hope of a crumbling empire, and you're in charge. I've been waiting for Steel Artery ever since it first popped onto my radar back in 2025, and it's finally pulled into the station. The self-branded 'train city builder' bears closest resemblance to the likes of colony sims in the vein of Rimworld and Oxygen Not Included. The big difference is that you're on a moving train. Boasting gorgeous pixel artwork and the need to exert careful influence on an autonomous, self-satisfying population, it's a rich simulation that will look different with every playthrough.

There's not much we love more than trains here at PCGamesN, but the best city builders might just take the cake. It's no surprise, then, that I've been immediately captivated by Steel Artery , which combines the two in stunning pixel-art fashion. A colony sim on rails in the truest sense of the phrase, it brings together the settlement management and construction of Rimworld and Oxygen Not Included, and the glorious chug of wheels clanking over the tracks. Travel across the land, keep your inhabitants happy, and grow your mobile behemoth into a thriving hub of commerce and production. Read the rest of the story...

- A small UI update - 25 March 2025
Hi everyone! I often get comments that the "technical" interface significantly spoils the impression of the game. I agree, so here’s a small change. This is still not the final version, but rather an intermediate one, since the white color has already started to annoy me a bit ;)
