CastleHero: Idle Tower Defense

Defend your castle with heroes on the walls and warriors on the battlefield.

CastleHero is an idle tower defense RPG where you build a hero army, strengthen your fortress and hold back waves of monsters. Prepare your formation, upgrade your archers and summon reinforcements before enemies reach your castle.

BUILD YOUR HERO ARMY
Recruit heroes with different combat roles and elemental powers. Place defenders in castle slots and assign field heroes to meet enemies on the ground as those positions unlock. Level up your favorites, unlock ascension and combine their strengths.

COMMAND YOUR CASTLE DEFENSE
Upgrade your fortress and archer garrison. Manage mana, deploy summoned units and activate hero skills as the battle unfolds. Enable automatic hero skills when you want to focus on reinforcements and the next threat.

CHALLENGE MONSTERS AND BOSSES
Face swarms, elite enemies, siege encounters and powerful fantasy bosses. Adjust your lineup and equipment as the campaign grows more demanding. Your next breakthrough starts with the team you prepare.

FORGE A STRONGER TEAM
Forge equipment, equip runes and collect artifacts that strengthen your heroes. Turn battle rewards into lasting upgrades and try new combinations for your next defense.

EARN GOLD WHILE YOU ARE AWAY
Collect up to six hours of gold earned while you are away. Spend it on your castle and heroes, then return to the battlefield ready for the next challenge.

EXPLORE YOUR REALM
Unlock Monster Hunt, Elemental Rift, Crown Gauntlet and Realm Raids. Gather resources, improve your roster and prepare for tougher challenges beyond the main campaign.

Build your heroes. Hold the line.
