How to play Asteroid Belt
Asteroid Belt is an asteroids-style vector shooter that runs right in your browser with nothing to install. You command a single, nimble ship adrift in a field of tumbling rocks. There is no gravity and no friction to speak of — only momentum — so flying well means thinking a moment ahead of where you already are. Rotate to aim, tap the thrusters to build speed, and fire a stream of shots to break the asteroids apart before they break you.
The goal
Survive the belt and rack up the highest score you can. Every asteroid you shoot scores points, and clearing the whole field advances you to the next wave, which spawns more rocks moving a little faster. You start with three lives; lose them all and the run is over. The belt is endless by design, so your true objective is endurance and accuracy under mounting pressure.
How asteroids behave
- Large asteroids drift slowly. Shoot one and it splits into two medium chunks.
- Shoot a medium chunk and it splits again into two small, fast fragments.
- Small fragments are worth the most points but are quick and easy to miss.
- The screen wraps: fly off one edge and you reappear on the opposite side — and so do the rocks and your bullets.
Controls
On a desktop, steer with the ← → arrow keys or A / D to rotate, ↑ or W to thrust, and Space to fire. On a phone or tablet, use the on-screen buttons below the play area: rotate left, thrust, rotate right, and a dedicated fire button. Touch is fully supported. Press N at any time to start a fresh game.
Strategy
Resist the urge to thrust constantly — a slow, controlled drift keeps you in command of your aim, while a runaway ship tends to slingshot straight into a rock it never saw coming. Clear the large asteroids from the edges of the field first so you are not boxed in by a cloud of fast fragments later in the wave. After you respawn you are briefly invulnerable, shown by a blinking ship; use that grace window to find open space before the shield fades. Your best score is saved on this device, so every wave you survive sets a target to beat on the next run.
