First you set up your base with an aircraft. Then you draw a line to send the aircraft or tank into the enemies. If the aircraft do not have their health gone they will go back to your base ready to attack again. You can also chain your attacks with the enimies. The further you go in the game the harder the enimies get. To get the aircraft to the enimies you simply draw a virtual line on the iPad.
