Infrastructure
Infrastructure sets population cap, improvement room, and baseline economic pace.
Growth and slots
- Each infrastructure adds 1,000 population cap.
- Infrastructure is bought in +100 chunks.
- V1 improvement slots scale from base 4, then add a slot every 500 infrastructure until the era cap.
Cost and pacing
- Base cost coefficient: 35,000 cash.
- Exponent: 1.72 with chunk multiplier 1.00.
- Build pacing shifts from 4 to 72 ticks per chunk as your nation grows.
Baseline economy effect
Infrastructure is both your expansion engine and your first upkeep commitment. The current baseline model publishes gross cash per infra per day and a matching maintenance rate, which is why the infrastructure cost calculator links directly into the baseline income and upkeep calculator.
Baseline gross cash per infra/day: 220
Infrastructure maintenance per infra/day: 28
