Game modes

The world has been covered by a strange Mist. Dense patches of it are not passable.

The Book of Insight is accessible between campaign missions. In it you can spend Insight to gain new abilities, unlock new pieces and improve the Citadel.

Combat

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.

Each troop has its own role, strengths and weaknesses.

• Lobbers are high-ground units that have more health and a range of 7 tiles. Attacks hit multiple horrors and do low damage. Cost: 60 Oxygen, 60 Wood, 4 Minerals. 2 Citizens, 1 Military Capacity. Maintenance: 30 Oxygen/min. Train Time: 30 seconds.
• Bowmen are low-ground units that have less health and a range of 9 tiles. Attacks hit one horror and do moderate damage. Cost: 45 Oxygen, 60 Wood, 1 Minerals. 1 Citizens, 1 Military Capacity. Maintenance: 30 Oxygen/min. Train Time: 30 seconds.
• Captors are low-ground units that slow down other units.

Different troops will fight better at different heights:

• Low-ground units get increased splash damage when at 4 meters or less above their target
• Hough-ground units have increased critical chance when at 5 meters or more above their target

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.

Prosperity

Each settlement has a level of Prosperity, which starts at 1. Once sufficient buildings and pieces have been constructed the Prosperity level can be increased.

Prosperity level 2 requires a Barracks and 50 points. Upgrading costs 360 Oxygen, 195 Wood and 45 Stone.
