The main city in Digimon World Next Order is Floatia. This is where you can get multiple daily rewards and activities. It is also where a lot of the story takes place and where you can train your Digimon.
It starts off as a small village, but it can expand into a huge city with several districts as you recruit more Digimon. I'm here to let you know how upgrading the city works.
How to Upgrade Floatia - What you need to unlock the expanded city and how upgrading works.
Districts and Buildings - The different districts and buildings you can get for the city.
As you recruit Digimon to the city, you open new functions and increases the Prosperity of Floatia.
To get the expanded city, you need at least 15 prosperity. If you don't get the city after that, continue through the story until you recruit Taomon. I had both of these at the same time, so not sure if Taomon is also a requirement.
Before you can start upgrading, you need Veemon to join the city. You can find him at the entrance to the Server Desert - Noise Storm.
Talk to him to find out that he and Togemon had a fight. After that, head to the Server Cemetery to talk to Togemon. Offer to help with Veemon, then go back to talk to Veemon. He will join the city to upgrade buildings.
You can also go back to Togemon and get him to join. Togemon will sell battle items in the item shop.
Now that you can upgrade, let's go over how it works. You can walk to the Central district, or press options and select "Central-Builder". This takes you to the building where Veemon is and lets you upgrade building.
Upgrading a building will add new functions or items. Each upgrade takes an in-game day and requires materials. The upgrades will tell you how many materials you need and how many you have.
There are 5 districts in Floatia: Central, Business, Agricultural, Research, and Entertainment.
