| DevBlog #107 | Foundry Fridays: New Loaders | 2026-07-10 | Hello everyone! Welcome back to another FOUNDRY Friday. Today we’re taking a look at a new take on loaders. One of the things we’ve been working on the past months was a re-interpretation of loaders, and while it’s still work in progress, we’re finally ready to show it. Redesign Goals Before we look at what we’ve come up with, let’s summarize the key points we were trying to achieve: Allow loaders to transfer from machine to machine without a belt. Allow loaders to transfer directly from belt to belt. Reduce the amount of unique items. Improve user-experience and reduce the amount of clicks needed. New Loader Design First, we parted ways with |
| DevBlog #106 | Foundry Fridays: More Work In Progress | 2026-06-26 | Hello everyone! In this FOUNDRY Friday I want to share various improvements of existing features that different team members have been working on. Increased Map Zoom In a previous update we already were able to improve the performance on how the map is generated, allowing us to to zoom out the map a tiny bit. But with trains and growing factories it felt like an even better overview of everything was needed. After another round of performance optimizations you can zoom out roughly 4 times more than before! Zoom level on the right image increased by ~4 times! Improved Train Management With the new Trains frame a better overview of your train f |
| DevBlog #105 | Foundry Fridays: Small Assembly Lines | 2026-06-12 | Hello everyone! In today’s FOUNDRY Friday I want to share something we have been experimenting with: Small Assembly Lines. in progress If you played the game for long enough, you have seen our Assembly Lines which are used to make the humanoid robots. Every step is visualized, and you can see the robots being manufactured step by step. That is a very unique feature and we think it deserves more attention, so we’re experimenting with bringing the small Bots to the Assembly Lines as well. For this to work we need a smaller, more beginner-friendly Assembly Line: Work in progress We believe this will further help us push some of the more unique m |
| DevBlog #104 | Foundry Fridays: Work in Progress | 2026-05-29 | Hello everyone! Last FOUNDRY Friday I asked about what you’d like to see next for the future, and the amount of responses was (pleasantly) surprising. We often get a lot of feedback in the comments or on Discord, but this time it was more than ever. Over 125 comments just on Steam (that’s over 9 pages!) and many more on other channels. It’s nice to see that there is genuine interest in the game and in the direction it develops. Rest assured that we have read every message and we’ll take them into account when we work out the plans for the future. We don’t have a fully scoped plan yet, regular work outside of supporting the launch of the last |
| DevBlog #103 | Foundry Fridays: What's next? | 2026-05-15 | Hello everyone! I’d like to start by thanking everyone who has played the game since Update 4 launched! Feedback has been positive and we’re glad that trains have finally arrived. We’ve been pretty busy monitoring the situation and reacting to any bug or issue reports, but ultimately this has been a relatively smooth update launch. What would you like to see next? As the dust settles on Update 4, we are getting ready to decide on what comes next. So it’s time to get that conversation going, and I’d like to hear your thoughts about what you think FOUNDRY needs the most. Whatever you’d like to see next, please let us know in the Steam comments |

| DevBlog #102 | Foundry Fridays: A Random Retrospective | 2026-05-01 | Foundry, from an Itch to RealityToday Foundry has Trains, Mega Nuclear Xeno power plants, and hundreds of hours of gameplay. But what has become a sprawling factory simulator, was once just a humble Itch.io game with a retro Minecraft aesthetic. The story of how Foundry came to be what it is today hasn’t really been told before, and I wanted to at least share my own first person account on the many random strokes of luck that allowed this game to exist the way it does today.A fortunate day in 2018Patrik, an avid Buildcraft and Factorio player, had a simple dream, to build the ultimate voxel factory game. And what now seems like an eternity ag |
| Update 4 Hotfix #1 is now live! | 2026-04-29 | Fixed crash that could occur when demolishing pipeline connected to a modular fluid tank. Fixed issue with robots not showing up in R&D lab after researching them. Fixed framerate dip that could occur when mining. Fixed issue with map icons sometimes being incorrect. Fixed issue where enabling the construction drone while in the galaxy view could cause the entire world to not render anymore. Fixed a bug with R&D lab XP calculation. Potential fix for players who were no longer able to start the game after Update 4. Pressing 'E' on a building now picks the closest screen panel to make fullscreen. Research Server will now show an error in the in |

| Community Mini-event: Petting zoo edition | 2026-04-20 | You’ve built factories. You’ve built quarrys. You’ve (not yet) built trains. But what about the friendly little critters around the planet? We were very impressed by your dedication to create the most enormous factories building robots, but now it’s time for another challenge. Pets. Animals. Mobs. Whatever you call them, they deserve something nice. How about you build some sort of pen for them? And while you’re at it, why not something that can enrich their environment. The discord, reddit & twitter (x, the everything app) is now open to taking submissions for the most impressive factory with integrated petting zoo / enclosure for various an |

| DevBlog #100 | Foundry Fridays: Xeno Power Plant | 2026-04-03 | Hello everyone! This is episode 100 of FOUNDRY Fridays! Time flies when you’re building the factory (game). Looking back, it’s incredible how the game has progressed over the years. Quite an improvement over our first version on itch, but also over the Early Access launch version from two years ago. From the bottom of my heart, thank you for your support through this journey. There’s a lot more to be done, so stay tuned!

| DevBlog #99 | Foundry Fridays: Update 4 Date & Construction Drone | 2026-03-20 | Hello everyone! Welcome back to another FOUNDRY Friday. Today I will be writing about the Update 4 progress and its planned release date, the construction drone and some smaller polishing we have added to the game. Update 4 Release Date & Progress We’re happy to announce that Update 4 is scheduled to release on Tuesday, the 28th of April. Due to us having worked on some of the new content (like trains) during previous update cycles, it allows us to go with a shorter timeline between the last and the upcoming update and we’re excited about that. Overall development progress is going well on several fronts. We’re making solid progress on the ne |
| DevBlog #98 | Foundry Fridays: More Quality Of Life | 2026-03-06 | Hello, dear robots! In this episode of Foundry Fridays I am excited to introduce… myself. My name is Omi, I recently joined the team to support all things game design. We are currently baking Update 4, and besides new content like trains we are also working on some Quality of Life features and various improvements to the early game. You might have already heard about the Info Overlay (U key) or the screen panel remote access (E key) in the last Foundry Friday episode. There are more things in the oven! For example, a remote controllable construction drone which should make early game building more comfortable. However, I won’t be talking much |
| DevBlog #97 | Foundry Fridays: Info Overlay | 2026-02-20 | Today, I’m excited to introduce a brand-new tool we’re working on to help you debug your factories more easily: the Info Overlay. Once released with the next update, you will be able to toggle the overlay at any time by pressing U, and it looks something like this: With the overlay enabled, you can instantly see what a building is producing from any side — no more running around trying to reach the screen panel: We’ve also added new pulsing status indicators, so you can quickly spot when something isn’t quite right. And if you want the details, the tooltip in the bottom-right will list the exact issues: Whether a machine is power strained, ha |
| DevBlog #96 | Foundry Fridays: Trains on Experimental | 2026-02-06 | Hello everyone! It’s been about two weeks since we launched Update 3 “Xeno Tech” and I wanted to take the time to say thanks to everyone who played the game so far. Many of you came back for the new content, and feedback has been very positive. We’re really happy to see the Steam reviews trending upwards and we will continue to work hard to improve FOUNDRY! Trains now on the Experimental Branch As some of you might already know, the Trains are now available on the experimental branch. We have quietly rolled them out on our Discord during the past two weeks to get some initial feedback and find the most serious bugs. It’s a big feature and we |

Naturally we’re now mostly focused on reacting to feedback and bug reports, but thanks to Update 3 being on the experimental branch for about 6 weeks this should be a smooth launch - fingers crossed! What’s next? Next up for us is of course Update 4, which will center around Trains, the new Power Plant and more Science Pack 5 content. On top of that we will look at improving some of the existing features. We don’t have a public timeline yet, but given we have already put in quite a bit of work on some of the Update 4 features |
