Galaxy Space Defender

Defend the cosmos against waves of alien invaders in Galaxy Space Defender! Take absolute command of an advanced starfighter locked in a high-stakes interstellar bullet-hell battle. Your critical mission is to blast incoming alien warships, dodge cascading plasma fire, and eliminate massive enemy bosses. Test your steering precision, unlock powerful weapon upgrades, and protect the galaxy!

Controls Move your Mouse cursor smoothly across the screen (or drag your thumb on mobile touchscreens) to guide your starfighter in any direction. The spaceship will shoot lasers automatically.

Rules & Strategy You must destroy all enemy fighter formations in each wave to advance to the next sector. Getting hit by alien bullets or colliding directly with enemy ships will deplete your health shield, leading to a system explosion game over. Do not just camp at the bottom center of the grid. It is highly recommended to patrol the lower screen corners in a wide U-shaped pattern, which allows you to steer clear of incoming laser walls while keeping a steady stream of counter-fire directed at the alien fleet.
