Citadel: Fortress Defense – Strategy & Progression

Start by securing food and stone. A solid foundation lets you raise stone walls before the first goblin wave hits. Place a mage tower near the entrance; magic fire slows enemy advance and buys time for archers. Rotate your towers to cover blind spots, then upgrade them when you earn renown. Each fifth day introduces a boss that forces you to rethink placement and unit composition.

Recruit knights for front‑line melee, archers for ranged pressure, and mages for crowd control. Switch between them with Q and E to react instantly to breach points. Use the market to trade excess wood for gold, then funnel gold into upgrades that boost health or damage. Keep an eye on the town hall; its fall ends the 1 Player survival run.

As the map expands, add new districts. A quarry supplies stone faster, a sawmill speeds wood collection, and a second barracks lets you field more soldiers. Balance expansion with defense—every new building creates a new vulnerable edge. The deeper you go, the tougher the enemy waves become, but the richer the loot, allowing you to push your castle into true Tower Defense mastery.

Remember that every decision echoes through the next raid. A well‑placed wall can save dozens of soldiers, while a missed upgrade can cost the entire settlement. Master the rhythm of building, fighting, and upgrading, and you’ll watch your citadel become an indomitable fortress.
