Time for a space shooter. As usual, save the earth before the aliens take over. Laser fire is enabled automatically whenever an enemy is above you. Keep an eye on your red health bar in the upper left corner. Whenever you are hit, your health decreases (and your score) more or less, depending on your damage. Adjust music and sound FX to your liking. Everything can be muted. Can you beat all alien invaders?
