Destroy different enemy tanks, while trying to keep them away from your base. When you have destroyed 20 enemy tanks you advance to the next level with different layout. In each level there's some obstacles which you can use to your advantage. Obstacles include red bricks which you can shoot out of your way, silver bricks which are highly armored, water and ice. You start the game with a basic tank, which you can power up to better one little by little.
