Defend Your Kingdom

Terrible news! The evil magician is back and he brings an army of Elemental with him! Since we did expel him from here, he must have only one reason to be here with that big army: he want to destroy our kingdom! Quickly put the new mobile defensive towers to work! You can choose whether they should aim automatically at the enemy or follow the aim of your mouse. Don't worry about firing as they will fire automatically the moment they finish reloading. To move each cannon you need to pay gold and once it is placed, it cannot be moved. The cannon does have a limited range so place each of them in a strategic location so that they can shoot as many enemy as possible. There are several upgrades you can put on each cannon after it is securely placed; elemental upgrade and physical upgrade. Elemental upgrade consists of fire, water or air elements and physical upgrade is simply moving additional cannon on top of the one already placed. For each enemy killed, you will receive some gold and for each enemy wave defeated, you will receive even more gold, so the more you win, the more you can upgrade your cannons. And don't forget to place some mines on the road so that if all your cannon fails, the enemy will still be blown to bits.
