Game Objectives:
The main purpose of the game is to defend our routes and bases against waves of giant insects. In order to do it and advance to the next stage, you must build turret defenses in strategic places of the scenario. Each enemies that reaches the other side of the screen or touches our bases without been killed by your defenses causes damage to the shield that is represented by a white bar in inferior part of the side bar, in the right side of the screen. When this shield is depleted the game is over. Each enemy killed by your defenses worth a small amount of money. Use this money to build new towers, to upgrade the existing ones or to repair the shield.
Building Defenses:
You must have enough money to build defense towers. The price is written below the name of the turret. Left Click or touch the available buttons in the right side of the screen, drag the turret icon to the desired place over an allowed construction site. A white circle is drawn around it to show the range of the selected turret. Release the mouse button or finger and the tower is built.
Upgrading Defenses:
Every tower in the game can be upgraded to increase its speed, range or damage in up to 5 levels, represented by five yellow stars just above the price’s button, as long as you have the money. First select the turret that you wish to upgrade. The upgrade bar is shown in the left side of the screen for the selected tower with its upgrade level for the three upgradable characteristics. The speed upgrade increases the turret rotation speed and fire rate, the range upgrade increases the maximum distance that the turret can shoot enemies and the damage upgrade increases the power of the attack against the insects.
Selling Towers:
If you are not satisfied with the position of any of the constructed towers you may sell it for half of the price spent with buying and upgrading it. Just click the button below the word “SELL” and you will receive the value shown in the sell button.
