Place your soldiers on the stone blocks to kill the enemies marching towards your fort gate. In each level, you have a certain number of lives and you lose one if an enemy enters through the portal. For each enemy killed, you earn 20 gold. There are also other gold coins to collect in each level with which you can buy upgrades for your soldiers or for your special attacks. There are 3 types of soldiers: pikeman with halberd, archer and knight.
