Welcome to Episode 2. You are getting a new unit, the Engineer, and access to the unit cycling buttons on the toolbar.
Developed resources are of no use unless they are transported to the capital city. The main function for the Engineer is to build a road network connecting developed resources to the capital city, where they can be used for industry or trade.
Resource tiles are considered “connected” if they have a road going through them, or are adjacent to a tile that has road in it. Resource tiles adjacent to the capital city or to other ports are also connected.
Click the question mark button on the lower right of the Main Map screen for explanations of road networks and of how to use the unit cycle buttons shown in the toolbar.
