Idle Boss Rush Global Steam

Crush the giants

IDLE BOSS RUSH is an incremental idle game packed with epic boss battles, where your kingdom grows even when you’re away. Start from a scrappy frontier camp and rise toward a thriving city - powered by an army strong enough to bring down colossal giants.

No trash mobs, no filler enemies - just giants. Each one demands time, planning, or a clever build to defeat. Watch towering foes loom over your town and then melt as your forces tear them down. Every victory matters.

Step away anytime - your troops keep fighting. Return to piles of loot, then dive back in to optimize builds, pierce tougher defenses, and speed up progression. Perfect for finding your balance between active min-maxing and chill idle growth.
