Foundation

A New Era of Organic City-Building Simulation!

Foundation: Harvest Festival is out now!

Greetings, Lords and Ladies,

The harvest is in. The Tavern is bustling, the tables are being prepared, and across the village, everyone has a part to play. Outside, orchards are heavy with fruit and pastures are alive with animals. Inside, your villagers are turning the countryside’s bounty into everything they need for a celebration. And before long, the Festival Grounds will be ready to welcome their guests.

Harvest Festival is available now!

A Growing Celebration

Bring your village together and watch a simple gathering grow into something truly spectacular.

Expand your Tavern with the new Festival Grounds and start planning a celebration your villagers will never forget. Gather food and drinks from across your village, decorate the grounds, and hire minstrels and jugglers as preparations get underway.

Every celebration can outshine the last. As your festival gains recognition, you’ll unlock new decorations and festival pieces, catch the eye of increasingly prestigious guests and earn the ultimate honour: a visit from the King himself!

A new Aspiration gives you a goal to pursue as you develop your agricultural economy and grow your celebrations.

Bring the Countryside to Life

Build a countryside full of life, from busy pastures filled with animals to orchards stretching out beyond your village.

Expand your rural economy with new cabbage and turnip crops, as well as apple, plum and hazelnut orchards, giving you even more freedom to shape the countryside around your village.

Raise chickens, pigs and geese in the new Common Croft, with pastures you can shape to fit naturally into your village. Watch chicks, piglets and goslings trail after their mothers while the village goes about its day.

Build an agricultural powerhouse or create a beautiful rural landscape, Harvest Festival gives you more ways to make the countryside your own.

From Pastures to Production

From the fields to the workshop, turn the fruits of your labour into something worth toasting.

The new Drying Kiln and Cider House give you new ways to process your harvest, while a new recipe system lets you switch recipes in both existing and new workplaces. Choose how your resources are used, open up new production chains, and turn the bounty of your countryside into goods for your growing village.

With more ways to grow, process and use your resources, the countryside becomes an even bigger part of your village’s journey towards the celebrations ahead.

Music for the Harvest

From quiet mornings in the countryside to lively celebrations at the Tavern, Harvest Festival brings 20 minutes of new music to Foundation, including the debut of the lute.

Free for Everyone: Today’s Base Game Update

Harvest Festival isn’t the only thing arriving today. We’ve also added several improvements to the base game for all Foundation players.

  • The Compendium: an in-game encyclopedia for recipes and mechanics, making it easier to keep track of the systems you’ve unlocked.
  • The Elegant Tavern: a refined new Tavern for your growing settlement.
  • Dawn: a new time of day, with soft, warm light and long shadows reaching across your fields.
  • Plus modular Sawmill parts, a round of UI improvements, including keyword search for buildings, and more!

A new Steam bundle featuring Foundation + Harvest Festival is now available.

For a limited time, players who already own Foundation can complete the bundle by purchasing only the DLC, while still benefiting from the bundle discount.

The table is set, Lords and Ladies. Show us your festivals!

Announcing Our First Major DLC – Foundation: Harvest Festival

Hear ye, hear ye, Merrymakers of the Realm!

Since we reached our full release, we have been hard at work dreaming up new ways to expand the medieval world you’ve built with us. Today, we are thrilled to pull back the curtain on our very first expansion: Foundation: Harvest Festival.

What is Foundation: Harvest Festival?

As we looked at where to take Foundation next, focusing on the heart of medieval life, the land felt like the most natural step. Rural agriculture was the backbone of any historical settlement, and we wanted to give you more agency over how your village sustains itself: livestock, orchards, vegetables and more…

Furthermore, we also wanted to break the rhythm of the villagers’ daily toil. Usually, your villagers are locked in a strict loop of work, needs, and free time. With this DLC, we are introducing a new narrative moment, The Harvest Festival, that allows your village to feel like a living, breathing society that knows how to pause and celebrate its hard work.

New Ways to Feed the Realm

The Harvest Festival DLC introduces several new agricultural layers to your economy:

  • The Common Croft: Diversify your livestock by raising chickens, pigs, and geese, providing new resources for your workplaces and markets.
  • Orchards: Plant beautiful groves to harvest apples, plums, and hazelnuts.
  • Vegetable Farms: A dedicated way to grow a variety of vegetables to keep your peasants’ larders full.
  • More workplaces to transform your resources, like the Cider House and the Drying Kiln
  • A new Workplace Recipe concept, allowing you to change a workplace’s transformation chain. For instance, the Butchery will be allowed to transform pigs into meat and animal fat.

A New Narrative Moment: The Harvest Festival

To crown your achievements, the Tavern is getting a major upgrade with the addition of the Festival Grounds sub-building. Here, you’ll organise grand Harvest Festivals, serving hearty meals and drinks while hiring entertainers to perform in a beautifully decorated communal area.

From a technical standpoint, this DLC marks a significant evolution of the game capabilities. This system allows us to inject spontaneous moments of life and shifts in the simulation’s rhythm. The Harvest Festival is the first major implementation of this system. By adding the new Festival Grounds to the tavern, you will be able to design a true community hub where the town stops to celebrate together.

A Little Something for Everyone…

While the DLC expands the countryside, the core game hasn’t been forgotten. Alongside this launch, we are preparing a free update for all players that reintroduces a fan-favourite building set.

While its specific identity remains a mystery for now, keep an eye out for a set of building parts that offer a touch more prestige and architectural flair to a well-appreciated monument. We know many of you missed these more refined visuals, and we’ve finally given them the glow-up they deserve to rejoin the core Foundation experience.

Foundation: Harvest Festival release is planned for this Summer (2026).

Devlog #20: Growing the Team and Expanding Foundation

Hello, city builders!

We hope your 2026 is off to a fantastic start and that you continue to enjoy growing your settlements. It has been inspiring to see the community’s response to our first post-1.0 Quality of Life update, and how positively the new tools and refinements have been received.

As we step into the new year, we wanted to share what has been happening behind the scenes, both in how the team is evolving and how we continue to support and develop Foundation. We have been hard at work, not just on the game itself, but also on building the team needed to take Foundation to the next level.


The Polymorph Family Is Expanding

To help us reach our goals for 2026, we have welcomed several new faces to the studio. We are thrilled to announce the addition of…

  • A New Project Manager: To help us stay on track and ensure our upcoming milestones are met with precision.
  • A UI/UX Artist: Dedicated to refining the interface and making your city-building experience more intuitive and comfortable to use.
  • New Programmers: Joining our technical department to accelerate the development of the new features we have planned, and to continue enhancing our game engine.

With these new team members, our ability to iterate, improve, and support Foundation over the long term has grown significantly.


Foundation in 2026: Strengthening the Core Experience… And of Course, Adding New Content!

Building on the success of the recent Quality of Life update, we are continuing to refine the core game experience with improvements, including how you build your settlements.

A frequent request from the community is for more flexibility when designing Monuments, specifically a way to align or smooth the height of various building parts. The team is currently working on making this a reality, focusing on providing the precision needed for more structured and impressive architectural designs.

Strengthening the core experience also means that we are continuing to review and improve the optimisation of both the game and the Hurricane engine. These under-the-hood efforts are key to ensuring that Foundation remains a seamless experience, while also supporting the further development of the game and new content.

New Content on the Horizon…

Alongside ongoing improvements, we know many of you are eager to know what is coming next for Foundation. We are excited to announce that two DLC projects are currently in development!

These upcoming expansions will introduce new content and features designed to fit seamlessly within Foundation’s current scope. Expect more depth, more variety for your villages, and of course, plenty of new content to explore.

While it is still too early to share more details, dedicated announcements for the first two DLCs are on the way, and we look forward to revealing more in the near future.


Thank you for your continued support and passion for Foundation. Your feedback, shared builds, and discussions inspire us to bring new ideas to life, and we look forward to showing you what we’re building!

Devlog #19: Development News

Hello everyone!

As the summer draws to a close and we see the first glimpses of autumn starting to show, it’s time for us to bring you some development news on Foundation!

How is development going?

We are sure this is a question on all of your minds and we’d first like to note that the game’s development is on track for our target release date.

Development is moving at a great pace and a lot has happened since our last Devlog:

  • Most gameplay features have been integrated such as Patrols, Walls and Fortifications and a new Military gameplay iteration.
  • We have worked a lot on the overall art direction of the game, including the lighting, vegetation and building revamps.
  • We are still hard at work on more technical features, like high density housing and paved roads.
  • We had a Community Private playtest where 150 players were invited to test and provide feedback (more on that later)

When will you reveal the new content and release date?

We will make further announcements as soon as we have integrated all that we feel needs to be in the game before publicly showing it. We are specifically working hard on the high density residential and the new environmental vegetation.

In the meantime, here’s a sneak peek of our work on the environment. This is in-engine stuff but please keep in mind that it’s work in progress.

How was the community Playtest and what was the feedback?

As we mentioned above there have been many changes since Devlog #18 and these changes and features have been integrated into the game. Players were invited to sign up for a private playtest on Discord so that we could gather feedback and make further improvements where necessary.

150 players took part in the private playtest and had a chance to test out the changes and work so far. The playtest ran from July 4 to July 15 and 98 of those playtesters completed the feedback form.

Of those 98 playtest responses, over 40% of them tested the game for more than 20 hours. 10% of the playtesters were totally new to the game, which gave us valuable insight into the learning curve for new players.

The feedback we gathered from the playtest was very positive and we received a lot of constructive comments. Some general conclusions from the playtest:

  • Safety, Patrols and Fortification were much appreciated, and we identified areas of improvement.
  • We had the new iteration of the Military system tested. A lot of interesting feedback was received, but that showed us there’s still some further iterations to do on this system.
  • Playtesters told us how much they love to build and customize their cities which has further focused us on the creative aspect of the game.
  • There was a lot of feedback on the UI/UX which will be a top priority for the full release.

Will there be another playtest?

Probably yes. 

We expect to do one more playtest before the full launch. If you would like to take part in any future playtests please join us on our Discord server for further playtest information.

What are you working on now?

On top of all the improvements and refinements based on the above playtest we are also focusing our work on:

  • High density housing  
  • Environment overhaul
  • Road handling and paved roads
  • Full art revamp of all remaining buildings
  • Improving the overall monument creation experience
  • Polish, polish, polish!

We will be back with further news once the last planned elements for the release version are ready to show. Stay tuned and thank you for your [more than we should be asking] patience!

Devlog #18: Dev News, Spring Sale & Bundle

Hi everyone and welcome to Devlog #18! 

We would first like to say a big (belated) welcome to 2024! This year the game marked its 5th year in Early Access and we have come a long way in those 5 years. There have been big changes to the game and we are powering through the final stretch to the full release of Foundation!

What we are working on right now

What are we working on is always the question we like to answer. The answer to this is nearly everything! The main theme of course is getting the game and all the planned content complete and ready for the full release and end of Early Access.

Some of the things we are currently working on include:

  • Map Edges – time to remove those hard-on-the-eyes map edges
  • The Castle – We know this is the one you are all waiting for!
  • Walls and Fortifications – Walls will have a cost to build like everything else but will also be part of the wider gameplay mechanics
  • Military Gameplay Improvements – Tied into the walls and fortifications, several changes are being worked on, such as setting patrols and creating “companies”
  • The Whole Art Direction –  including fully overhauled buildings as well as major environmental improvements
  • Monument Design Experience – Adding capabilities such as the ability to replace parts and move an entire monument, as well as a full user interface revamp

Oh! And of course Housing and Residential improvements and changes. A lot of work is going on to get the Housing visuals where we want them to be, as well as bring in the 3rd tier high-density residential. The biggest factor is having the housing look authentically medieval within our style setting but ultimately give housing that wow factor!

Residential concept art

Due to the work-in-progress state of current development, we aren’t quite ready to show too much of what we have been working on, partly to not spoil a bigger reveal announcement but also due to things just not being polished and ready quite yet.

We are aware that you want to hear more and you will soon! Look out for a big announcement coming in the next few months!

Early Access Updates

Some of you may be wondering when the game will receive a new update. As previously announced, the next major update will be the end of Early Access and the Full Release of the game. We do not plan to release any more updates between now and the full release. 

With the final development at full steam ahead, the whole team is dedicated to completing the game, polishing the rough edges and presenting to you the Foundation that we imagined and that you want.

We can’t wait to show you the result of all the hard work and share the date of the full release. 

Watch this space!

Steam Spring Sale: Buy Foundation at a Discounted Price!

That’s all for now but we’ll be sharing more news in the coming months and in the meantime please keep sharing any feedback and bug reports on our official Discord server.
