How to create a Project Zomboid Build 42 server

Project Zomboid Build 42 already runs in multiplayer. On RoxyCloud you enable it in the panel, on Annihilation and Ultimate. You do not install a dedicated server on your PC.

1. Hire the right plan

1. Open the Project Zomboid hosting page.
2. Pick Annihilation or Ultimate.
3. Pay and wait for the panel email. Activation takes a few minutes.
4. Save the IP, port and panel password.

2. Enable Build 42 in the panel

The server starts on the stable build (41 today). To pull 42 you change the Steam branch in the panel.

1. Open the RoxyCloud panel and the Project Zomboid server.
2. Go to Settings, then General.
3. In the beta branch field type exactly: unstable
4. Save.
5. If a world exists, download the save in the file manager.
6. Stop the server with Power.
7. Delete the game install files and reinstall from the panel. SteamCMD downloads Build 42.
8. Start again and wait for the first boot to finish.

unstable

unstable is the Steam branch name. No quotes, no capitals, no spaces.

3. Name, password and map

Still in the panel, set the basics before you invite the group.

• Server name
• Admin password
• Join password, if the room is closed
• Map and PvP in the save .ini (file manager)
• Workshop mods, if you want them. The other guide on this blog covers that.

Save and click Start (Power). If the console sits on the 42 download, wait. A large pack is slow the first time.

4. How to join

1. On the PC, Project Zomboid must be Build 42. If Steam still ships 41 on the default branch, enable unstable in the game properties.
2. Open Join.
3. Paste the panel IP.
4. Paste the panel port.
5. Type the room password if there is one.
6. Connect.

After it is online

• Keep auto update on if you want to follow the unstable branch. A 42 patch can break a mod.
• Back up from the panel. A 42 world changes fast.
• Mods: IDs in the .ini, Build 42 backslash format. See the mods guide.
• Panel questions: ticket or WhatsApp in RoxyCloud business hours. Saturday 11:00 to 15:00.
