Every next mission will become harder and harder, enemies will grow stronger and smarter, enemy radars and cannons will appear making it more difficult to complete your mission. We recommend you to take advantage of hints between levels and bonuses located in the game field — they will help you to defeat your enemy.

For completing missions and destroying enemy vehicles, you will earn coins which you will be able to spend in the workshop for improving your tank or buying weapons. The more powerful the enemy vehicle is, the more money you will get for destroying it. And after completing a level, you will get additional 5% to the earned amount (in the workshop this percentage can be increased). You can use this money to upgrade your tank (i.e. purchase better chassis or increase its speed) thus making it almost invincible to enemy cannons.

Also you can spend it for purchasing vehicles and other weapons.
