FireBat: Idle Defense

Small squad. Serious firepower.

Build your own flame-powered squad in FireBat: Idle Defense. Merge equipment, position your FireBats, and take on waves of monsters in a colorful sci-fi world.

Automatic battles, hands-on strategy
Your FireBats attack enemies in range automatically. Drag them onto deployment tiles and adjust their positions around the monster route. Upgrade attack power, attack speed, and gold income as you push through tougher stages.

Merge your way to stronger gear
Combine two pieces of equipment at the same level to create a stronger one. Develop your equipment from Common to Mythic and grow your squad's firepower. Unlock more deployment slots and bring up to 10 FireBats into battle.

Break through monster waves and bosses
Clear timed stages and face powerful bosses. When a stage is too tough, improve your equipment, rethink your formation, and try again with a stronger squad.

Collect heroes and power up
Unlock a roster of armored heroes with distinct appearances and permanent ownership bonuses. Choose your favorite look and strengthen your squad as your collection grows.

Unleash explosive skills
Unlock and upgrade mines, lightning, and nuclear attacks. Equip your skills and use their different effects to support your FireBats against advancing enemies.

Mine minerals and challenge the dungeon
Hire workers to gather minerals and take on the Mineral Dungeon for first-clear rewards. Spend your minerals on equipment draws, heroes, and more ways to develop your squad.

Rebirth for lasting progress
Start a new run with permanent upgrades. Invest your rebirth stones in attack power, attack speed, and gold income to reach further with each return.

Keep growing between sessions
Collect offline gold when you return and use it to prepare for your next challenge.

An internet connection is required.
