Orbit Breaker: Rock Siege

Orbit Breaker: Rock Siege is an original orbital gravity-well arcade shooter that runs entirely in your browser. No download, no account, no install. You fly a ship around a central planet, using its gravity to slingshot into bonus points, dodge incoming rock fields, and split rocks into smaller hazards before they crowd your path. Every fifth wave a boss arrives, and you must read its attack pattern and survive long enough to break through. The whole game is built from scratch in a single page: every sprite is drawn live on a canvas each frame, and every sound effect is synthesized in real time with WebAudio, so there are zero image or audio asset files to load. Your local high score is saved in the browser so you can chase your own best run. It is fast, tight, and retro in spirit without being a reskin of Asteroids. The gravity-slingshot mechanic and the escalating boss design make it its own thing. It is free to play and built for short, repeatable sessions.
