Idle Hero Defense: Monster Invasion

Monsters attack in endless waves, and only one hero is left to defend the line. In Idle Hero Defense: Monster Invasion, everything centers on automatic battles and constantly upgrading your fighter. It is a defense game where the outcome depends on how fast you improve your warrior. The hero fights on his own, lands blows, and stops monsters from getting through. Your job is to power him up by unlocking new abilities and boosting his attack stats.

How to play?

At the start, the hero stands in one spot and holds off the first monsters. You earn gold for every enemy you defeat. In the game, you spend this gold on upgrades, increasing your attack power, attack speed, and special moves. After each upgrade, the hero becomes clearly stronger and can fight much longer before going down. Keep an eye on the enemy waves, because the farther you go, the tougher they get. If you upgrade your hero in time, you can hold the defense and unlock new levels. Want to see how far your hero can go? Then jump in, build up your defenses, and do not let the monsters break through.
