The zombie apocalypse waits for no one, but your Project Zomboid world does. You and your friends have fortified a safehouse, stockpiled canned food and weapons, barricaded the windows, and established a sustainable base. Then the host goes offline, and your carefully prepared compound sits empty while the zombie population keeps growing in your imagination.

Project Zomboid’s multiplayer save is locked to the server host. SaveSync unlocks it for your entire group.

Why Project Zomboid Co-Op Saves Are Complicated

Project Zomboid multiplayer works through a server model. One player hosts a server (either through the in-game hosting option or a standalone dedicated server), and the world save lives on that machine. Other players connect as clients.

The challenge is that Project Zomboid server saves are not simple single files. They include the map data, player inventories, zombie populations, vehicle states, and world metadata. This complexity makes manual file transfers particularly error-prone. Drop a file, miss a folder, and your safehouse might vanish or your vehicle fleet could reset.

How SaveSync Handles the Complexity

SaveSync is built to handle multi-file game saves. It synchronizes the entire Project Zomboid server save directory across your group, preserving the complete world state including all the intricate data that makes your apocalypse unique.

When the current host finishes a session and syncs, any other group member can pull the complete save, host the server, and the world continues exactly where it left off. Barricades intact. Loot where you left it. Zombies still lurking outside.

How to Set Up SaveSync for Project Zomboid

  1. Install SaveSync from Steam.
  2. Create a sync group and invite your fellow survivors through Steam.
  3. Select Project Zomboid and configure the server save location.
  4. Sync the full save directory after each session.
  5. Any group member can host by pulling the latest save and launching the server.

Why Use SaveSync Instead of Other Methods?

vs. Dedicated server hosting: Running a Project Zomboid dedicated server 24/7 means either leaving a machine on constantly or paying for hosting. For a group that plays a few times a week, most of that uptime is wasted. SaveSync lets any player host on demand without ongoing costs.

vs. Manually copying server files: Project Zomboid server saves are complex directory structures with many interdependent files. Manually zipping and transferring them is risky. Miss one folder and the world could load in a broken state. SaveSync captures the entire save structure every time.

vs. Starting over when the host is unavailable: In Project Zomboid, progress is slow and hard-won. Every nail, every plank, every can of beans matters. Starting a new world because the host is busy means losing weeks of careful survival. SaveSync makes sure that never happens.

This Is How You Survived

In Project Zomboid, survival is about preparation, patience, and persistence. SaveSync adds one more survival tool to your kit: the ability to keep your world going no matter what happens in real life. Because in Knox County, every day you are not fortifying is a day the zombies are closing in.
