Asteroids
Pilot a ship through a field of drifting asteroids. Rotate, thrust, and shoot to destroy them before they destroy you. Screen wraps in all directions.
Play NowAbout
A vector-style space shooter that captures the feel of the arcade original. Pilot your ship through open space, using thrust and rotation to navigate while blasting asteroids into smaller and smaller fragments.
Large asteroids split into two medium ones when hit, and medium ones split into two small ones. Each wave adds more asteroids and increases their speed. The screen wraps — fly off one edge and you appear on the opposite side. A brief invincibility period protects you at the start of each wave.

Small asteroids are worth 10 points, medium 20, and large 30. Clearing a wave earns a bonus based on the wave number. Your personal best and last five scores are stored locally in your browser.
