Quick answer
Defense starts as a resource decision: soldiers, walls, and safety all cost materials that could have gone into growth.
Defense Route
- Do not ignore defense once enemies appear or combat achievements start showing up.
- Train soldiers after the town guards building unlocks, especially if enemy pressure is interrupting progress.
- Upgrade walls and defenses when survival risk becomes more expensive than the materials spent.
- Balance military growth with food and worker capacity so the settlement does not stall.
Combat Milestones
Achievement data gives the page a useful structure: First Contact marks the first enemy encounter, Walls of Stone points toward wall upgrades, Standing Strong connects to a major army fight, and Flawless Victory turns defense into a challenge objective.
When To Spend On Defense
Spend on defense when attacks are costing more than the upgrades you are delaying. If the economy is stable and enemies are starting to interrupt progress, guards and walls become production tools, not just protection.
