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.
- MASSIVE FULLY AUTOMATED BATTLES
Watch the action unfold as your heroes clash against 150+ enemies per wave. Every decision matters: a single hero swap can completely turn the tide.
- DEEPLY CUSTOMIZABLE TOWER
Build your tower your way. Push your damage 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 draw unwanted attention. Ancient beings, some older than time itself, will hunt you down. Slay them and claim artifacts of terrifying power.
How many waves can you survive?
