Destroy. Upgrade. Destroy some more.
Welcome to Idle Asteroids, an explosive upgrade on the arcade classic. Watch your spaceship, face endless waves of escalating cosmic threats, and destroy them!
Whether you want to actively dodge and weave through a bullet hell of space rocks, or build an automated dreadnought that destroys everything in its path, Idle Asteroids delivers that satisfying "numbers go up" while I watch things blow up feeling all while wrapped in comfy arcade nostalgia.
Build Your Arsenal
Start simple and evolve into a asteroid-clearing war machine.
Weapons: Upgrade your cannon, launch homing missiles, deploy explosive mines and more to vaporize enemies getting too close.
Special Abilities: Overwhelmed? Drop a Singularity black hole to suck in nearby asteroids, or when all else fails why not launch a Nuclear Warhead, it's the only way to be sure.
Tactical Defense: Upgrade your Hull, recharge your Shields, and master the Warp Dash!
Escalating Cosmic Threats
The universe doesn't want you here, and it will throw increasingly complex dangers your way:
Asteroids: We have an endless supply of space rocks that just need to be turned into cosmic dust.
Flying Saucers: The eternal foe. We don't remember why, we just shoot on sight.
And more devious enemies as you progress through the rounds and levels.
⚙️ Deep Permanent Progression
With over 50 upgrades across multiple categories, every run matters.
Active vs. Idle Play: Tap or click anywhere to manually deal damage to the nearest enemy, or invest heavily in Mining Drones that autonomously harvest asteroids for passive income.
Infinite Scaling: Push your Best Round to increase your Universal Player Bonus, a global multiplier that makes every future upgrade even more powerful.
AFK: Level up your automation enough, and you can comfortably idle through earlier rounds while your drones and auto-turrets do the work.
