A vector-style space shooter in the browser tab: rotate and thrust your ship, blast drifting rocks before they hit you, and watch each hit split into smaller fragments. No install, no account, nothing uploaded.
Rotate, thrust, and fire at drifting rocks in an open field that wraps at every edge. Loads instantly - then it runs entirely in this tab.
Asteroid Blaster
Press Play and your ship drops into an open field of drifting rocks. Turn with the left and right arrow keys, hold up to thrust forward, and tap space to fire. Every rock you hit splits into three smaller fragments until the pieces are too small to split any further, so a single big rock can turn into a screenful of debris fast. The play field wraps at every edge - fly off the right side and you reappear on the left.
Every so often a lone alien ship drifts in from one side of the screen and fires back at you and at the rocks in its path; destroying it is worth more points than a rock. You start with two spare ships shown in the corner - lose your current ship and the next one respawns a moment later once the wreckage clears, as long as a spare remains. Clear every rock on the field and the next wave adds one more rock than the last, up to a cap of twelve at once.

It plays with a keyboard - phones and tablets can load the page, but there are no touch controls, so a desktop or laptop is the way to play. Nothing is saved between visits: there is no score list and no account, so every run starts fresh from an empty field. The game makes no network calls after it loads and keeps no record of how you played.
This is an adapted, rebranded build of a small open-source game engine (MIT license); the original bundled font file carried no reusable license, so the on-screen score and messages are drawn with a plain browser font instead, and the two sound effects are separately credited, Creative-Commons-licensed recordings. Full credits and license text ship next to the game files.
Frequently Asked Questions
What does Asteroid Blaster do?
It is a browser space shooter: turn and thrust a ship with the arrow keys, fire with space, and break apart drifting rocks before they hit you. Each rock splits into three smaller pieces when shot, and an occasional alien ship drifts in and fires back.
Does it work on a phone?
No - the game is controlled with arrow keys and the space bar, and it has no touch controls. On a phone or tablet the page and the game load, but you cannot turn, thrust, or fire; use a desktop or laptop.
Is anything saved in my browser?
No. There is no score list, save, or account - each visit starts a fresh run, and the game makes no network calls after it loads.
What happens when I lose a ship?
You start with two spare ships, shown as small icons in the corner. Lose your current ship and, if a spare remains, a new one appears a moment after the wreckage clears. Run out of spares and the round ends.
