Moon Swarm

From the Devs

Defend your moon in this idle auto-battler that lives quietly in the corner of your screen.

Fend off endless waves of alien creatures, build powerful defenses, collect gold, and unlock new weapons and planets while you work, browse, or play.

Build Your Defense

Place defensive guns and watch them automatically fight off waves of aliens. Upgrade your defenses and create a setup that can handle increasingly dangerous enemies.

Upgrade & Grow

Collect gold from defeated aliens and spend it on powerful upgrades. Improve your damage, fire rate, range, and other abilities to make your defenses stronger.

Unlock New Weapons

Discover new defensive weapons, each with its own strengths and playstyle. Experiment with different combinations to find your perfect setup.

Explore New Planets

Survive the waves and travel to new planets, each bringing new challenges, enemies, and environments to defend.

Always on Your Desktop

The game runs in a small corner of your screen, letting you defend your moon while you work, browse the web, watch videos, or play other games.

Play Your Way

Keep an eye on the action and upgrade when needed, or let your defenses do the work while you focus on other things. Your moon is always under attack!
