Travel to the space and fight the aliens who are desperate to destroy the whole universe. Shoot the alien bees and butterflies with your space ship special weapons. Use the arrow keys to move your ship around and avoid the incoming fire from the aliens. Hit the space bar key to fire back. If you get hit by the missiles or get a collision with an alien space ship, you will loose one life. The aliens will keep appearing on the platform and align to form a strong army. Aim and fire carefully and timely to destroy all the aliens to clear the level. Galaga is the pioneer of all the space shooting games and still possesses an addictive gameplay.
