In Zombie Idle Defense Online, you get to save the world from silly zombies! You build super cool defenses like turrets and traps to keep the zombies away from your base. The best part? You don’t even have to keep clicking! Your defenses work for you while you play other games! When zombies get too close, you can zap them or call in epic heroes to help! There are tons of different zombies to battle, and you collect coins to upgrade your stuff. Team up with friends or go solo – it’s so much fun to beat the zombie waves and save the day!
