Only One Tower - Idle Defense

Only One Tower - Idle Defense is a tower defense game where you have just one tower to protect. Choose your upgrades wisely, recruit powerful Heroes, and hold the line against endless waves of increasingly deadly enemies.

• FULLY AUTOMATED LARGE-SCALE BATTLER

Watch auto battles unfold as your heroes clash against 150+ enemies per wave. Every decision matters — a single unit swap could completely overturn your strategy.

• DEEPLY CUSTOMIZABLE TOWER

Build your tower your way. Push your damage output until you're wiping out hundreds of enemies per second, or go full tank and become truly unkillable. No two builds are the same.

• THE ANCIENTS ARE COMING

Grow strong enough, and you'll eventually draw unwanted attention. Ancient beings - some older than Time itself - will hunt you down. Slay them, and claim artifacts of terrifying power.
