Use arrow keys or WASD to move the ship in all 4 directions. Press Space to shoot bullets. On mobile, use the on-screen touch buttons.
Large asteroids are worth 20 points, medium ones 50 points, and small ones 100 points. Large asteroids split into 2 medium asteroids when hit, and medium ones split into 2 small asteroids.
Destroy all asteroids on screen to advance to the next level. Each level spawns more asteroids at higher speeds, increasing the difficulty.
You start with 3 lives. Colliding with an asteroid costs 1 life. Losing all lives ends the game. After a collision, you gain brief invincibility.
Breaking large asteroids first fills the screen quickly, so manage your space carefully. Use screen edges (objects wrap around), keep moving, and pick off smaller fragments when safe.
Asteroid Destroyer is a classic arcade-style space shooter where you pilot a spaceship to destroy floating asteroids with bullets. Inspired by the timeless 1979 Atari classic, it features rotation-and-thrust controls and asteroids that split into smaller fragments when hit. Simple yet addictive gameplay that sharpens your reflexes and spatial awareness. Challenge yourself as each level introduces more asteroids at higher speeds.
