Server Hosting

The following documentation details how to host a public or private game server for Holdfast: Nations At War. The game offers an anonymous dedicated server for both Linux and Windows.

Quick Start Guide

Quick start guide for local testing:

1. Download Holdfast: Nations At War - Dedicated Server from Steam (Tools section).
2. Change the map rotation file (serverconfig_default.txt) and add mods or change maps.
3. Launch the server using LaunchServer.ps1 (Windows) or LaunchServer.sh (Linux).

• In Holdfast’s server browser click **Join Custom Server**, then click the top **Connect** (leave localhost; change the port if required).
• If you want other players to connect, you’ll likely need to set up port forwarding on your router and open the ports in your local firewall.

Warning: Game updates will overwrite the changes to the LaunchServer script and serverconfig_default.txt. To prevent this, create copies of both files and change the arguments of your custom LaunchServer script to point to your custom serverconfig file.

Windows

Obtaining the game files

Download using Steam Client

The easiest way is through Steam using the Holdfast: Nations At War - Dedicated Server app in your library.

1. Open your Steam Library. 2. Choose **Tools** in the library filter (or search for holdfast and tick **Tools**). 3. Install **Holdfast: Nations At War - Dedicated Server**. 4. After install, right-click the app → **Manage** → **Browse local files**.
