01 / Mission brief

Classic arcade instinct.
Modern network combat.

Asteroids Net turns the timeless asteroid run into a connected 3D dogfight.

Fly a model-rendered starship through a living starfield, dodge debris, track enemies on radar, and race to five kills. The host maintains the authoritative match state while compact UDP updates keep the action moving without blocking the render loop.
