SteamWorld Builder is a city-building simulator with a SteamWorld twist. Gamers will have to manage and improve their city in a post-apocalyptic robotic world so that they can advance their underground mining outposts. As players progress through the game, they'll reach new milestones and unlock professions, which give them access to all sorts of useful buildings.

SteamWorld Build: Every Map, Explained

Discover all the maps in Steamworld Build and find out what each one has to offer in this comprehensive guide.

This guide will tell players everything they need to know about upgrading buildings in SteamWorld Building, including which milestones are crucial and how to meet their citizens' needs.

How to Upgrade Buildings

Players will start SteamWorld Build with the ability to construct Worker Residential buildings. At first, they won't need much more than a connection to the train station, but as fans progress, they will have to work harder to satisfy their needs.

If citizen needs are met, residential will hold more people, meaning more workers will be available. On top of this, once needs have been completely satisfied, gamers will be able to upgrade a residential to the next citizen type if they've already unlocked the required milestone.

How to Unlock All Buildings

Players will have access to Worker Residentials as soon as they start a new SteamWorld Build save, but they will have to work towards the next upgrades. Acquiring all residential buildings is necessary since it's how you gain access to other professions, so gamers must focus on unlocking them as soon as possible.
