A swarm of alien UFOs is attacking Earth's oceans! You are the planet's only hope of defense.
Launch colored balls from the ocean surface to take down the invaders. To destroy a UFO, the color of your projectile must match the color of the target. Keep an eye out for special gold balls, which can destroy any UFO regardless of color!
Be careful! Each time a UFO or even your own projectile hits the water, the ocean level rises. The higher the water gets, the harder your mission becomes.
