Shoot the number of enemies according the level, and finally fight with the enemy king.
Waves of attacking enemies are to be destroyed by our Hero.
At the end of every wave:
The Hero can buy gun updates having lesser bullet lag times.
He can also buy updates for lesser % health loss. This applies to soldiers only and not to other enemies.
When a bullet from an enemy hits the fort the health gets reduced by a certain percentage. When the health becomes 0 the game ends.
Keep the mouse pressed to shoot continuously. Release the mouse, and drag the cursor to rotate the gun and change the direction of shooting.
