Zombie Idle Defense Online is a strategy game with role-playing elements set in a post-apocalyptic world. Most of the population has turned into ferocious zombies, and a small survivor needs help to fight back.
Together with a group of survivors, defend yourself against endless waves of zombies. Your defenders keep fighting even while you plan your next move, which is what makes it an idle game. Use your rewards to strengthen the team, improve your defences and push back bigger waves. The atmosphere is tense, and the gameplay rewards careful thinking.
