Tribes of War. Your goal is to protect your tribe from incoming enemies. You can select which enemy you want to fight: Knights, or Zombies. You can also select a difficulty level from 1 to 6. Use materials to place tiles. You get more materials from killed enemies. At the start you get some unemployed "members". You can place these on walls and they will attack enemies. Be aware that you do not get any extra unemployed members during the fight. The few at the start is all you have, defend them well!
