Frontiers introduces the concept of large living breathing planetary settlements which travellers can encounter, interact with and even be elected Overseer of. As the leader of your adopted people, travellers can choose to help them, even lead them, ensure their future prosperity and happiness and ultimately develop these fledgling towns into even larger towns.
You are able to construct new buildings, to see your town grow as you welcome new inhabitants. Citizens will look to you to help solve their problems, make important decisions, keep them safely below sentinel radars, and help defend against drone attacks.
