Fortress Defense: Castle

Defend your base in this 3D tower defense strategy game! Choose tower locations, build a defensive line, and halt enemies advancing wave after wave.
Each new level generates a unique battlefield with enemy paths. Combine rapid-fire, flamethrower, explosive, and slowing towers; lay mines; and prepare to face bosses. Earn coins in battle to upgrade your defenses.
When enemies close in on your base, deploy a bomb, activate a damage aura, or restore the base's health. Win matches to earn diamonds and unlock permanent upgrades—such as new towers, a sturdier base, and a higher starting coin balance.
Strategize your tower placement, experiment with ability combinations, and defend your base across new maps. Can you stop the next wave?
