Our earth is overloaded with evil spirits. You, as a guardian of the earth, are ordered to shoot on sight any evil spirit wandering around. Beware of shooting any good guy. We look forward to a better world.

1. Evil spirits(bad guys) and good spirits(good guys) will wander around the sky every 5 seconds. 2. Shoot all those bad guys as many as possible and avoid shooting at the good guys. The killing of a good guy carries a penalty which will deduct some points from your total score. Demon offers you the highest points followed by Bad Boss and Bad Guy. 3. For effective killing, try to take aim at the centre of a target when firing.
