About the Game

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 60

Currently, each zombie can evolve up to level 125. Content is available up to level 60. Each level up requires DNA and improves your stats.

In the current update, your zombies will be able to upgrade at level 20, 40: new sprite, stat multiplier, and a more prominent presence in this arid desert.

Unexpected events & new gameplay loops

This update introduces a new gameplay loop centered around unexpected events, bringing resources, collectibles, and added variety to progression.

One event is currently available, with five more planned to expand the system in future updates.

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.
