Defense Center

The Defense Center lets you build planetary defenses and provides an automatic garrison. Upgrading it expands its capabilities and speeds up defense construction.

Open its panel, check which defenses you have unlocked and review the order cost. Keep the units you build separate from the garrison the Center supplies.

A destroyed garrison recovers over time. After an attack, check the losses and the current defense status before assuming the planet is protected. Pair defenses with information about your enemy and an economy that can replace losses.
