Kill the giant bats and place bombs to explode them. Stay alive in your little helicopter. First, follow the tutorial to learn how to play. You can either shoot or throw a bomb. Remember that it is possible to use the speed of the helicopter to drop a bomb much further than simply dropping it without moving. When you have completed the training, you can start your first mission. Eliminate all giant bats in the country.
Use the mouse to shoot and to move and Space to throw a bomb or to detonate.
