Star Rupture Dedicated Server Setup 2026

Setting up your own Star Rupture dedicated server allows you to maintain a persistent factory world for up to 4 players. This guide covers the experimental dedicated server setup process.

Prerequisites

Hardware Requirements

Step 1: Install SteamCMD

SteamCMD is Valve's command-line tool for downloading game server files.

Windows Setup

1. Download SteamCMD from Valve's website
2. Extract to a folder (e.g., C:\steamcmd)
3. Run steamcmd.exe

Step 2: Download Star Rupture Server

Launch SteamCMD and run the following commands:

# Set installation directory
force_install_dir C:\StarRuptureServer

# Login anonymously (no Steam account required)
login anonymous

# Download Star Rupture dedicated server files (App ID: 3809400)
app_update 3809400 validate

# Exit SteamCMD
quit

@echo off
steamcmd +force_install_dir C:\StarRuptureServer +login anonymous +app_update 3809400 validate +quit

Step 3: Configure Server Settings

Navigate to your server directory and create/edit configuration files:

Windows Configuration

Location: C:\StarRuptureServer\StarRupture\Saved\Config\WindowsServer\Game.ini

[/Script/StarRupture.StarRuptureGameMode]
ServerName="My Star Rupture Server"
MaxPlayers=4
ServerPassword=""
AdminPassword="your_admin_password"
DifficultyLevel=Normal
DayLengthSeconds=3600

Step 4: Launch the Server

Windows Launch

Create a batch file start_server.bat:

@echo off
cd C:\StarRuptureServer
start StarRuptureServer.exe -log -Port=27015

Double-click the batch file to start your server.

Step 5: Port Forwarding

Open the following ports on your router and firewall:

Windows Firewall

New-NetFirewallRule -DisplayName "Star Rupture UDP 27015" -Direction Inbound -LocalPort 27015 -Protocol UDP -Action Allow
New-NetFirewallRule -DisplayName "Star Rupture UDP 27016" -Direction Inbound -LocalPort 27016 -Protocol UDP -Action Allow

SaveSync Host Migration

Star Rupture features SaveSync, allowing players to host and transfer world saves seamlessly:

Using SaveSync

1. Create your world as host
2. Invite players to join
3. If you need to disconnect, use SaveSync to transfer the world
4. Another player can become the new host
5. All progress is preserved

Connecting to Your Server

Direct Connection

1. Launch Star Rupture
2. Select "Multiplayer"
3. Choose "Direct Connect"
4. Enter server IP and port (e.g., 123.45.67.89:27015)
5. Click "Connect"
