Introduction

You can host your own Afterinfection server on your VPS at ZapX. Afterinfection is not included in the Game Server Installer, and unlike many other games, the server is not available through Steam or SteamCMD. This guide explains the current hosting situation, what you need, and what to keep in mind when setting everything up manually.

Afterinfection: Set Up a Server on Your VPS

Requirements

Requirement	Afterinfection
Operating system	Windows Server. Afterinfection is only available for Windows, and a Linux server is not documented.
Server files	Server files provided by the developer (no SteamCMD download)
Steam	Steam must be installed and running on your VPS
Access	Remote Desktop

Info

Afterinfection is not available in the Game Server Installer. If your VPS is running Linux, install a Windows Server template via Settings > Reinstallation. This deletes all data on your VPS. Learn more in Server Reinstallation.

Current hosting situation

The developer supports player-hosted servers and provides the server files directly. The latest published version (server files v21) was linked in the official Steam news for update 0.2.1 in June 2023. The old download page on the game’s website is no longer available. According to the developer, new server files are available through the game’s official Discord server, linked on the game’s Steam page.

Warning

There is currently no official step-by-step guide, port list, or configuration documentation. Before setting up your server, check that the server files match the current game version. Otherwise, players may not be able to connect.

Set up Afterinfection

Connect to your VPS using Remote Desktop.
Install the Steam client and sign in. According to community reports, the server only appears in the server list if Steam is running on the VPS.
Download the latest server files from the developer and extract them to a dedicated folder, for example, C:\GameServers\afterinfection.
Start the server using the included executable and follow the developer’s instructions for the server files.

To have the server start automatically after your VPS restarts, create a task in Task Scheduler that runs the server when the system starts. Make sure Steam starts as well.

Ports and firewall

The developer does not publicly document which ports the server uses. Server operators report on the Steam forum that they have opened ports 2222 and 55555. Allow your server’s ports in the Windows Firewall (Manage Windows Defender Firewall rules) and also open them in the ZapX dashboard under the Network Firewall tab for your VPS. Since the protocol is not documented, allow the ports for both UDP and TCP.

Backups

Stop the server and regularly copy the server folder to a safe location. 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 backups. Learn more in Daily backups, restoration, and locked actions.

More information

For the latest information about updates and server files, check the Afterinfection Steam news and the game’s official Discord server, linked on the Steam page.

Conclusion

Setting up your own Afterinfection server takes a little more manual work than it does for other games because there is no official download through Steam.
