IdleZomb: Manage a ruined hospital, create zombies, evolve them, or sacrifice them for DNA. Every decision counts in this post-apocalyptic management game. Early Access focuses on the basics, with content available up to level 20.
IdleZomb
SteamWelcome 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.
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.
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.
Currently, each zombie can evolve up to level 125. Content is available up to level 40. Each level up requires DNA and improves your stats.
In the current update, your zombies will be able to upgrade at level 20: new sprite, stat multiplier, and a more prominent presence in this arid desert.
Future planned mechanics will introduce other gameplay loops, such as unexpected events that will provide collectibles and resources, further diversifying the gameplay.
However, this feature is not yet available.
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.
