Buildings

Every settlement will begin with a Citadel, which produces 180 Oxygen, 8 Citizens and 10 Military Capacity and stores resources. 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.

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

A buildings 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. Buildings left without Support will be highlighted red.

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

Buildings can be stacked on top of other buildings if there is room.

A gap made traversable with wood pieces

Wood Pieces are quick, cheap and require less Support but their Toughness is low. The are perfect for quickly building complex structures and reaching distant places.

• Primary
  • Wood Strut
• Secondary
  • Wood Half Arch
• Stairs
  • Wood Steps

Stone Bricks changing appearance as stacked

Stone Pieces are resilient but require more Support. They are the key to building tough walls and hardy structures

• Primary
  • Stone Brick: Stone Bricks gain additional Toughness if they are stacked in rows of 3 and even more if they are stacked in rows of 6.
• Secondary
  • Stone Half Arch
• Stairs
  • Stone Steps

Advanced Pieces

• Doors allow human units to pass through walls and gain additional Toughness if embedded in Stone Bricks.
  • Door
  • Double Door

Piece	Effect	Cost
Merlon	Boosts the range of any unit behind it and upgrades the Toughness of stone pieces below it	6 Stone
