Idle Hero TD

Idle Hero TD is an idle tower defense game where you assemble heroes, build defenses and battle endless waves of monsters. Auto-battle lets your heroes fight for you, while your team continues to progress and earn rewards when the game is closed. You can play actively or return to collect offline resources and loot.

Heroes and upgrades

Unlock 48 unique heroes with different skill sets, then combine their abilities to build an effective team. Ranking heroes up unlocks new mechanics, and early-game heroes can remain useful in the end game. You also level up heroes, unlock abilities and upgrade towers, using gold, resources and loot from each wave to strengthen your defense over successive runs.

A wide range of resources unlocks millions of upgrades, including Research, Prestige Power, Spells, Technology, Runes, Tournament Points and Mastery Points. The game offers simple auto-battle mechanics alongside strategic choices about hero combinations, tower synergies and long-term progression.

Challenges and maps

You can fight Ultra Bosses and Immortal Bosses, compete in PvP Tournaments and leaderboards, and join Weekly Community Challenges with other players. Weekly community events, daily missions, achievements and other challenges provide additional goals. Several maps have different perks and call for different defensive strategies.

Cross-platform play

Cross-play and cross-platform functionality lets you continue your progress on PC and mobile devices. You can also compete with players around the world.
