Ground defenses

A dispersed, semi-autonomous network of small, hidden weapon installations which makes the prospect of a direct ground assault and even simple raids extremely costly to the attacker. Only overwhelming orbital bombardment or massively disproportionate active screening can suppress these defenses.

–In-game description

Ground Defences are a non-industry structure that can be built at any Colony. They may optionally be upgraded to Heavy Batteries.

Ground Defences cost 150 000 credits to construct, and have a build time of 60 days.


  • x2 multiplier of colony ground force
  • +1 Stability
  • Shortages will reduce the ground force multiplier proportionally


  • 1,000 * (pop size - 2), multiplied by market upkeep modifier (hazard rating)


Ground Defences do not produce any commodities.
