Explore nearby terrain with rangers to reveal resources, chokepoints, and infected clusters. Build a stable economy by placing housing and food producers, then add sawmills, quarries, and power for sustained growth. Expand methodically with patrols and lookout towers, clearing threats while securing space for farms and industry. Fortify perimeter lines with layered walls, gates, towers, and traps, repairing immediately to stop infection spread. Research advanced tech to unlock stone, oil, heavy defenses, and late-game firepower against massive swarms. Prepare for timed hordes and the final onslaught by assigning control groups, scouting attack directions, and concentrating defenses.
