Frontier City is a simulation game in which the player must build a city in a harsh, post-apocalyptic environment. The game challenges players to manage scarce resources, including water and electricity, while building a city that can provide food and daily necessities to its citizens. Players must use strategic planning to ensure that water and electricity can reach all areas of the city in order to thrive and grow. As the city expands and takes in survivors from around the world, players must continue to manage resources and build infrastructure, all while facing new challenges and threats in the wasteland.
