Every settlement will begin with a Citadel, which produces 180 Oxygen, stores 720 Oxygen, 400 Wood, 400 Stone and 200 Minerals, and projects territory around it. It produces 10 Military Capacity and can be upgraded to produce more. It also comes with two towers where buildings may be placed, ideally Air Filters. All buildings need a path to the Citadel to function and will shut down if pieces facilitating this are destroyed or recycled. If the Citadel is destroyed the mission is lost.

Raw Materials buildings use workers who carry materials from the resource gathering building to the nearest Warehouse or Citadel. The shorter the distance, the faster resources will be gathered. The buildings come in two levels and can be upgraded for the cost difference once the required Prosperity is reached.
 
Each building has one worker and can have as many additional workers assigned as there are Citizens available. The optimal number of workers depends on the number of resources around and the distance to the nearest warehouse or the citadel.
* If the number of workers is colored white, additional workers will increase production.
* If the number of workers is colored green, the building has the optimal amount of workers assigned for maximum production.
* If the number of workers is colored red, the building has more workers assigned than necessary for maximum production.

Buildings must be placed within owned territory, which is projected around the Citadel and Beacons. Pieces can be built anywhere.

Each building has an Oxygen maintenance cost that depends on the game difficulty.

A building can only be placed where it has enough Support from below. If sections providing Support are destroyed or removed the supported building may collapse. When time is paused a building won't collapse without Support and will be highlighted red.

You can recycle placed buildings to recover their resources by pressing the recycle button below the build menu and then clicking on the buildings you want recycled.

The Citadel

The Citadel

Every settlement will begin with a Citadel, which produces 180 Oxygen, stores 720 Oxygen, 400 Wood, 400 Stone and 200 Minerals, and projects territory around it. It produces 10 Military Capacity and can be upgraded to produce more. It also comes with two towers where buildings may be placed, ideally Air Filters. All buildings need a path to the Citadel to function and will shut down if pieces facilitating this are destroyed or recycled. If the Citadel is destroyed the mission is lost.

The Citadel has a health of 400, which is increased to 650 with the Reinforced Stonework skill and to 1150 with the Reinforced Stonework II skill.

The Citadel produces 10 Citizens on Story difficulty, 8 Citizens on Easy/Normal/Hard difficulty and 6 Citizens on Extreme difficulty.

With the Headquarters Defense skill from the Book of Insight the Citadel gains an ability to damage all horrors around it. With the Mistleap skill from the Book of Insight the Citadel gains an ability to teleport all units in the selected area to the Citadel.

Resource Gathering

Resource Gathering buildings are used to produce resources.

Raw Materials

Raw Materials buildings use workers who carry materials from the resource gathering building to the nearest Warehouse or Citadel. The shorter the distance, the faster resources will be gathered. The buildings come in two levels and can be upgraded for the cost difference once the required Prosperity is reached.

Each building has one worker and can have as many additional workers assigned as there are Citizens available. The optimal number of workers depends on the number of resources around and the distance to the nearest warehouse or the citadel.

  • If the number of workers is colored white, additional workers will increase production.
  • If the number of workers is colored green, the building has the optimal amount of workers assigned for maximum production.
  • If the number of workers is colored red, the building has more workers assigned than necessary for maximum production.
