The city dome was destroyed when attacking the city. The digital station that supported it was under repair and the enemy decided to take advantage of this in order to win the city for himself. You will have several hundred resources to ensure the defense of the city. Use them wisely and arrange the security towers along the perimeter. Subsequently, they can be improved for the same resources that are extracted over time or fall after the destruction of the enemy. Provide an indestructible defense of your city using all the means that are available in the game. Be careful the enemy can launch an attack from either side, so do not rush to install guns in disagreement.
