Attention! The enemy is attacking! Your task is to use all your forces to defend the base. To do this, just select a unit and draw a line of defense. The soldiers immediately rush into battle. But, do not forget that training new fighters costs money. And the stronger the army, the more money you have to spend. Therefore, try to calculate the battle tactics in advance and bring exactly as many units onto the field as may be required to win. Otherwise, your gold reserves will quickly run out and it will be difficult to achieve victory.
