Idle Boss Rush

Idle Boss Rush is an incremental idle game about building a town and raising an army to defeat giant bosses. Your progress continues while you are away, and you advance from a wretched camp to a lively city and eventually a grand kingdom.

Build your kingdom

Manage residents and resources as you develop your town. Choose structures and synergistic upgrades, and customize the land as your settlement grows.

Fight the giants

Bosses take time or a good strategy to defeat, and each kill matters. Giants are visible from anywhere in town as they melt during the fights. Your troops can battle automatically while you are away, or you can take control and optimize your build for particular bosses to make faster progress. The game lets you balance active and passive play, and includes BOSS RUSH challenges that award permanent bonuses. Prestige is optional.

Combine upgrades

Upgrade items to reveal additional effects. Choose advisors specializing in military, economy or magic, then equip them with powerful items. Combine their abilities with synergistic town upgrades to create combinations that help you defeat bosses faster. Mechanics are gradually unboxed, and item upgrades are complex.
