A long time ago began a war between two empires. Your army has lost recent battles and very soon the enemies will reach your home land. All your tanks and other military equipment has been destroyed during the war and the only way to stop the enemy troops is to place powerful defense towers in their way. Eliminate them all, nobody should pass your defense. If they pass your defense your empire will fall.
Build defense towers to stop the enemies. Destroy all enemy units before they reach red flags. If they pass your defense you will loose lives. Click on a tower to see it's stats, upgrade or sell the selected tower.
