The aliens have invaded the planet. They have turned each place into a dark and gloomy land. Join the army of survivors and get rid of these invaders here in Crusade. The mission you need to accomplish here is to use a specialized cannon that can take out the souls of the invaders. You must accurately adjust the power and aim of your cannon to hit them perfectly. You can shoot as many shots as you can but you will receive less bonus points if you do. If you can kill all the invaders with one shot, you will receive a gold medal.
