Citadel: Fortress Defense – Strategy Tips

Start by laying a solid foundation. Place farms and sawmills near each other; they feed wood and food without extra travel time. Upgrade stone walls before you add decorative towers—walls absorb the first wave of goblins and bandits. Keep a mix of knights, archers, and mages in your barracks; each enemy type reacts differently. Goblins rush low walls, skeletons ignore arrows but crumble under magic, and bandits target resource buildings. Position mage towers behind stone barriers so their spells reach the front without being cut down.

When a raid begins, switch to soldier control with Q or E. Direct a knight to block the main gate while an archer picks off advancing foes from a tower. Use the rotate command (R) to angle your towers toward the most threatening direction. If a wall segment is breached, press X to demolish the damaged piece and rebuild instantly with B‑1. This prevents enemies from using the gap as a shortcut.

Every fifth day a boss appears. Save renown for upgrades that boost health and damage of your elite units. Upgrading the market unlocks faster gold income, which fuels higher‑tier weapons for your knights. Remember that survival hinges on balance: over‑investing in offense leaves your food supply vulnerable, while neglecting defense invites endless waves.

Play in 1 Player mode to fine‑tune your castle layout without external pressure. The endless survival loop rewards careful planning; each successful raid grants resources and renown, letting you expand the land and raise new walls. The more you survive, the more the game reveals—new building types, stronger enemies, and deeper layers of tower defense tactics.
