After death took over the desert, you have to start a dangerous journey to reach the castle to survive. In Medieval Defense Z, the challenging Online Medieval Zombie Survival Game, you have to control a moving tower pulled by a donkey and use archers to fight off waves of attacking zombies. Collect money to hire and power-up archers to defend your king and your loyal donkey. After every stage is cleared, you will earn one upgrade, such as extra health, arrows rain and other devastating powers you can unleash during your battles. Keep advancing to charge your special attacks and try to reach the castle alive. Enjoy!
