Idle Asteroids

Idle Asteroids is an arcade space game about surviving waves of increasingly dangerous cosmic threats. You pilot a spaceship, destroy asteroids and other enemies, and improve your weapons and defenses. You can dodge and attack actively or invest in automation that keeps fighting while you idle.

Weapons and defense

Upgrade your cannon, launch homing missiles and deploy explosive mines to destroy nearby enemies. Special abilities include the Singularity, which creates a black hole that pulls in nearby asteroids, and a Nuclear Warhead. You can also upgrade your Hull, recharge your Shields and use the Warp Dash.

Enemies and progression

Asteroids arrive in endless supply, and Flying Saucers are another recurring enemy. More enemies appear as you progress through rounds and levels. Over 50 upgrades span multiple categories, and upgrades and stats remain permanent between runs.

Tap or click anywhere to deal damage manually to the nearest enemy, or invest in Mining Drones that harvest asteroids autonomously for passive income. Improving your automation lets drones and auto-turrets handle earlier rounds while you idle. Raising your Best Round increases the Universal Player Bonus, a global multiplier that strengthens future upgrades.

Arcade features

The game uses crisp, color-coded vector graphics. Global Leaderboards track the highest Level and Round, and Steam Achievements mark milestones.
