To pass each level, your task is to destroy the enemy's main tank. The more enemies you kill, the more money and points you'll be able to earn, and you'll be able to improve your rank. If you do not get enough money needed to upgrade your tank, the money will not reset and you can continue to save enough money to upgrade your tank.
