New Update - April 29,2022 - Alliance Dependent Territory

You can establish dependent territories outside the metropolitan territory. A dependent territory consists of 5 - 6 border cities and there must be no other cities in the dependency. Click the 'Dependency' button on your city, you can set up the borders. The borders can be your or other members' cities.

There will be a minor alliance flag showing at the dependency location on the map when you finished.

Dependency cities have a 15% defense bonus. The dependency will disappear when any one of the borders is lost. Alliance capital and border cities can not be set as dependency city.
