F2 A! Idle Army

F2 A! Idle Army is an idle strategy game centred on building and upgrading an army to fight off increasingly powerful monsters. Players upgrade their hero, purchase units, boost resource production, and unlock technology to strengthen their forces over time.

Combat is fully automated, with units fighting without direct player control. As progress is made, additional unit combinations become available, allowing the army to expand and grow stronger against tougher enemies. The game includes hundreds of technology upgrades that can be unlocked to enhance both the hero and the units.

The hero character cannot be defeated, and fallen army units respawn automatically, removing the possibility of failure. The game consists of ongoing waves of enemies and increasing numerical progression, designed for low-pressure, passive play.
