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.

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.

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 peasant's 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.

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.

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). Stay tuned for more news on this upcoming DLC.
