Star Defender

Start with the core loop

Play Star Defender free online. Move your ship, shoot descending alien waves, dodge their fire, and survive faster and faster levels.

Move with arrows or touch and fire with Space or the on-screen control.

Build a better run

Alien formations, projectile pressure, lives, and faster waves build a score-driven survival run.

Play with intent

Clear dangerous columns first, move between shots, and preserve lateral escape space near the edges.
