Castle Defense pits your castle against relentless monster waves across two connected modes: a Castle Builder where you place buildings, grow your economy, research upgrades and recruit heroes, and Combat — scrolling lane battles where trait-rich monsters, status effects and controllable heroes decide whether your gate holds.
From Swordsmen and Archers to Paladins, Battle Mages and a late-game Dragon.
A full bestiary of armored, regenerating, splitting and flying threats.
Recruit and level heroes with active abilities and game-changing ultimates.
Place 23+ buildings, upgrade your keep, and unlock research.
