Strategy

Winning isn’t about brute force; it’s about out‑thinking the enemy. Start by placing archers where they can pick off low‑HP monsters before they reach the walls. Switch to melee units when a heavy War beast appears – the right formation can turn a losing battle into a victory. Upgrade each soldier’s weapon in the Puzzle‑style tech tree, then experiment with 3D visual upgrades that boost range and damage. Remember: the “draw” line you sketch determines whether a wave stalls or crashes through. Keep an eye on the Brain meter; a full meter triggers a temporary shield that can buy you precious seconds during a boss rush. As you progress, new enemy types demand fresh tactics – fire‑breathing drakes need ice arrows, while armored trolls require flank attacks. Master the rhythm, adapt on the fly, and the castle will stand.
