IdleZomb — Create. Sacrifice. Evolve. Welcome to IdleZomb , a management game where the twist is… your NPCs are zombies. No villagers to protect here you build, optimize, and experiment using the undead. Sacrificed in the name of progress. In a ruined world, you take control of an abandoned hospital — the starting point for a potential new species… One that might be more evolved than the one that destroyed everything. Start with a single zombie Every game begins with a single randomly generated zombie. Its stats will determine its value… and its chances of survival. Put it to work: harvesting, producing, upgrading… Or sacrifice it to extract precious strands of DNA. Rebuild your base Your hospital is the heart of the system. It's where new zombies are born. Nearby, a rundown lab houses a strange figure — one who can butcher your zombies to harvest their DNA. But… are you sure he has good intentions? That’s a question worth remembering. Content up to level 20 For now, each zombie can evolve up to level 20. Each level requires DNA and boosts its stats. In a future update, reaching level 20 will trigger a major evolution: new sprite, stat multiplier, and a more imposing presence in this arid wasteland. But for now, that stage isn’t available yet. A world to rebuild… one chicken at a time At first, your zombies will only face chickens — harmless and barely nourishing. With time, they’ll encounter mutant rats tougher foes... And far worse creatures in future updates. An Early Access in progress IdleZomb is under active development. This early beta is just the first slice of the project. More content, new creatures, gameplay systems, and building types are planned for the coming months. Your feedback is essential. An experimental version ⚠️ This version is not representative of the final game.
