Monsters are preparing to attack your city. Your objective in this cool defense game is to defend the city at all costs by building defense towers to attack the monsters. Use YOUR MOUSE and place the towers strategically to inflict maximum damage to your foes. There are several types of towers. Fire: good damage with medium range (attacks air & land units). Wind: less damage with good range. Can slow a single enemy (air & land). Lightning: very good damage and good range (air only). Ice: little damage with short range, but will slow your enemies. Earth: good damage with small range (land only). Ultimate: excellent damage with a very large range. Good luck!
