Antiair tower

The antiair tower is unsurprisingly the most effective destroyer of flying enemies.Until forth upgrade level they fire what could be a shell containing esplosives, as although there is only one or two simultaneous shots, the enemy suffers several explosions thereafter. The range is not overly great until antiair towers are upgraded to forth or fifth level. Then they have good range(and fire homing missiles instead). Missiles explode when their' targeted enemy is destroyed so congestion of missile towers is not effective. Provided with amp towers missile launching antiair towers can cover most of a moderate sized map with their' fire and even in the last few waves little missiles are needed to take out stings and flyers. Flying queens are another matter altogether.
