Galaga is the legendary space shooter that defined the shoot-em-up genre. Inspired by the 1981 Namco classic, this free online version puts you in command of a lone starfighter defending against waves of alien invaders that swoop and dive in mesmerizing attack patterns. Enemies aren't just sitting targets — they break formation and dive-bomb your position with increasing aggression. Shoot them down, dodge their attacks, and survive wave after wave as the alien armada throws everything it has at you. Power-ups add double-shot capability and temporary shields to help you fight back. Play Galaga online free and experience the pure arcade thrill of defending Earth one wave at a time. Simple controls, fast action, and that addictive "just one more wave" feeling make this a perfect quick-play game.
How to Play Galaga
Use arrow keys or A/D to move your ship left and right along the bottom of the screen. Press Space to fire. Your ship can fire up to two shots at a time.
Enemy formations appear at the top of the screen, then individual aliens break away to dive at you in swooping attack patterns. Shoot them during formation or during their attacks — attacking enemies are worth more points.
Destroy all enemies in a wave to advance to the next one. Waves get harder with faster enemies and more aggressive attack patterns. Collect power-ups that drop from defeated enemies: double shot lets you fire two bullets side by side, and shields absorb one hit.
Galaga Tips & Strategies
- Stay near the center to maximize your ability to dodge in either direction.
- Prioritize attacking enemies — they're the immediate threat and worth more points.
- Learn the dive patterns — enemies follow predictable swooping paths you can memorize.
- Don't chase enemies to the screen edges — you'll get trapped by the next attacker.
- Grab the double-shot power-up whenever possible — it doubles your firepower.
- Focus fire on one enemy at a time rather than spraying shots across the formation.
