Units

Every night swarms of horrors will attack the settlement. Every night before the attack red arrows will show the directions of the attacking swarms and a curved bar on top will show the remaining time until they attack. Hovering over the attack direction arrow will list the attacking units. After surviving the first night the horrors will know about the settlement and individual ones can attack during the day as well.

All humans fight from distance. Hovering over a human will display its range.

The number of troops that can be trained is limited by the Military Capacity, which starts at 10 and is increased at the Citadel. A rally point can be set by selected by selecting a building that produces units and right-clicking where newly recruited units should move.

All units have a maintenance cost of 30 Oxygen/min. Units received as reinforcements during a mission do not have maintenance costs.

Each troop has its own preferred height compared to the enemy and will receive increased bonuses when attacking from their preferred height. The amount of health units have depends on game difficulty.

Horrors can also create Broodnests to take control of an area. Broodnests erupt during night or if attacked, releasing horrors. Horrors can also defile an Ancient Beacon, making it impossible to build nearby.
