What the developers have to say:

Why Early Access?

“IdleZomb is a solo indie project. Early Access allows players to get involved right away and provide ongoing feedback. This helps improve, balance, and expand the game in ways that reflect the community's expectations.
The current version has a solid foundation and is ready to grow based on public input.”

Approximately how long will this game be in Early Access?

“There is no fixed release date. The goal is to continue developing IdleZomb until it reaches a stable, feature-rich, and well-balanced 1.0 version.”

How is the full version planned to differ from the Early Access version?

“The game is expected to expand progressively. New features, content, and balancing adjustments are planned throughout development.
Community feedback will help shape development priorities.”

What is the current state of the Early Access version?

“The current version includes the following:

- A zombie creation system with randomized stat management.
- A central hospital serving as the main hub and allowing for unit upgrades.
- A laboratory allowing the sacrifice of units to obtain essential resources.
- Basic resources and their acquisition systems: meat, stone, cactus fiber, DNA, and runes.
- A construction system with a dedicated menu, including the progressive unlocking of buildings.
- Integrated tutorials to guide the learning of the mechanics.
- Keyboard shortcuts for easier navigation.
- A refined interface, already designed to be as user-friendly as possible.
- A bunker featuring a complete skill tree, with all 35 bonuses accessible in this second version.
- A functional PvE system, with three different enemies, each with its own unique mechanics.
- A class system for zombies with three choices.”

Will the game be priced differently during and after Early Access?

“The price may be reevaluated over time as new content and features are added. No final decision has been made yet.”

How are you planning on involving the Community in your development process?

“Via a Discord server and Steam feedback. I will take player feedback into account to improve gameplay, add content, and prioritize certain features.”

About This 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 40

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.

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.
Many systems are still in development, sounds are not yet integrated,
