Your country is under attack by hostile tanks! Enter the warzone and take part in fierce battles. Do you have what it takes to stop the invasion?

Your tank is painted green.
Use the arrow keys to move in any of the four directions (you cannot move diagonally). Pressing Space will fire a bullet. If you want to return to the main menu, press the Esc key. Remember that your progress will not be saved if you exit midgame.

There are many different objects on the battlefield. The most important ones are listed here:

* Brick walls can be destroyed by firing bullets at them.
* Steel walls are impossible to destroy. Take advantage of this fact - they provide good shelter from incoming bullets.
* Water acts as an obstacle to your tank. However, bullets will pass over it.
* Don't get too close to the flames, or else your tank will explode.
* Turbo paths accelerate your tank. They can slow you down if used in the wrong direction.
* Trees give you cover. Keep in mind that the opposing tanks may also hide under them!

Hostile tanks differ in speed and behaviour. If you accidentally crash with another tank, you lose a life. Destroy all enemy tanks to complete the level. The number of remaining lives is shown in the top left corner.

There are various power-ups which will appear on the battlefield from time to time. These will help you against the overwhelming forces of the enemy.

* Clock freezes all enemy tanks for a short period of time.
* Shield makes you invincible for a couple of seconds.
* Heart gives you an additional life.
