How to Install Mods on Your Abiotic Factor Server

Install PAK mods and UE4SS mods on your Abiotic Factor dedicated server from Nexus Mods — no Steam Workshop support.

Abiotic Factor does not support Steam Workshop. Mods come from Nexus Mods and are installed manually. There are two types:

Type	Install location	Complexity
PAK mods	`AbioticFactor/Content/Paks/`	Simple — drop files in
UE4SS mods	Requires UE4SS mod loader	Advanced — needs loader setup

PAK mods are the simplest type — they add or replace game assets.

Get the mod from Nexus Mods - Abiotic Factor. Look for files ending in .pak, .utoc, or .ucas.

In the XGamingServer Panel, go to Console and stop the server.

Click Files in the sidebar. Navigate to AbioticFactor/Content/Paks/ and upload the mod files.

Start from Console. Players need the same mods installed client-side.

UE4SS mods use Lua or C++ scripts and require the UE4SS mod loader.

Download UE4SS and upload the loader files to the server. The key file is version.dll which goes in the server's binary directory.

Place UE4SS mods in the Mods/ folder created by the loader, following each mod's install instructions.

Start from Console.

UE4SS setup on dedicated servers can be tricky. Check each mod's Nexus page for server-specific instructions.

Do Players Need the Mods?

Yes — most mods must be installed on both the server and all connecting clients. Mismatched mods cause connection failures.
