Introduction

Host your own TerraTech Worlds server on your VPS at ZapX.

This guide explains what you need, how installation works, and how to manage your TerraTech Worlds server afterward.

TerraTech Worlds: Set Up a Server on Your VPS

Requirements

Requirement	TerraTech Worlds
Operating system	Windows Server 2019 or newer
Memory	At least 6 GB
Free disk space	At least 14 GB on drive C:

Info

TerraTech Worlds is only available for Windows in the Game Server Installer. If your VPS runs Linux, install a Windows Server template via Settings > Reinstallation. This deletes all data on your VPS. For more information, see Server Reinstallation.

Install TerraTech Worlds

Open your VPS in the ZapX dashboard and go to the Tools tab. Select the Game Server Installer.
Under Your server's operating system, select the Windows tile.
Under Choose game, search for TerraTech Worlds and select it.
Under Set up server, enter a Server name. For TerraTech Worlds, this is the name of your save. Also choose the Player slots (up to 8) and select the Niburu or Phaeton planet under Map. You can find the Game port under Advanced settings.
Click Install on this VPS, then Start installation.

The installer downloads and sets up the TerraTech Worlds server via SteamCMD, then starts it. For details on the installation process, see the Game Server Installer guide.

Info

The first startup takes about 30 seconds while the server loads the planet. The server uses around 2.2 GB of memory when no players are connected.

You can also install TerraTech Worlds yourself using a command: copy the command displayed in the final step, connect via Remote Desktop, and run it in Windows PowerShell as an administrator.

After installation

Once installation is complete, the installer displays your server address under How to connect. You can view any passwords generated by the installer under Login credentials—they are shown only once. Read on to learn how to connect.

Your server files are located on the VPS at C:\ZapX-GameServers\terratech-worlds\:

Folder/file	Contents
`server\`	TerraTech Worlds server files
`server\TT2\Saved\`	Your worlds and saves
`server\dedicated_server_config.json`	Server settings
`logs\server.log`	Server output

Connect to the server

You can find your VPS IP address in the Overview of your VPS in the ZapX dashboard. The installer shows the full address under Connect to. Start TerraTech Worlds and join the server by IP. Enter your VPS IP address and the port, which is 15636 by default.

Start, stop, and restart the server

Your TerraTech Worlds server starts automatically when the VPS boots and restarts if it crashes. To manage it, connect via Remote Desktop and use the desktop shortcuts:

TerraTech Worlds (terratech-worlds) - Start
TerraTech Worlds (terratech-worlds) - Stop
TerraTech Worlds (terratech-worlds) - Restart

The Stop shortcut shuts down the server gracefully. This takes about 20 seconds.

Configuration

TerraTech Worlds settings are in server\dedicated_server_config.json. These include, for example, day length, resource yield, enemy threat, and saves. The installer overwrites the port, player slots, password, save, and planet each time it runs, so change these through the installer. You can edit all other settings yourself. Stop the server before making changes, then start it again afterward. Passwords are stored in plain text in this file and therefore also appear in every backup.

Update the server

Updates are not installed automatically. To update, open the Game Server Installer again and select TerraTech Worlds. The installer detects the existing installation and displays Update. Alternatively, use the TerraTech Worlds (terratech-worlds) - Update shortcut on the VPS. Your settings and saves will be preserved.

Ports and firewall

Port	Protocol	Use
15636	UDP	Game

The installer opens these ports in the Windows Firewall. If you start the installation from the dashboard, it also opens them in your VPS's Network Firewall. If you installed using a command, check the ports there yourself.

Backups

Use the TerraTech Worlds (terratech-worlds) - Backup shortcut to save your worlds and saves, as well as dedicated_server_config.json, to a ZIP file in C:\ZapX-GameServers\_backups\terratech-worlds\. Use TerraTech Worlds (terratech-worlds) - Restore to restore a backup.

Your entire VPS is also backed up automatically every day. With an active ZapX Pass, you can restore these backups yourself and create your own. For more information, see Daily backups, restores, and restricted actions.

Your TerraTech Worlds server is now running on your VPS. If you have questions or need help, our support team is here for you every day! 🙂
