Installing Mods

First, go to your Deadlock installation folder by right-clicking the game in your Steam library and selecting Manage > Browse local files.

Open the gameinfo.gi file located in game/citadel with any text editor. Find the FileSystem section and modify it like this:

gameinfo.gi

    FileSystem
    {
    	//
    	// The code that loads this file automatically does a few things here:
    	//
    	// 1. For each "Game" search path, it adds a "GameBin" path, in <dir>\bin
    	// 2. For each "Game" search path, it adds another "Game" path in front of it with _<language> at the end.
    	//    For example: c:\hl2\cstrike on a french machine would get a c:\hl2\cstrike_french path added to it.
    	// 3. If no "Mod" key, for the first "Game" search path, it adds a search path called "MOD".
    	// 4. If no "Write" key, for the first "Game" search path, it adds a search path called "DEFAULT_WRITE_PATH".
    	//
 
    	//
    	// Search paths are relative to the exe directory\..\
    	//
    	SearchPaths
    	{
			// These are optional language paths. They must be mounted first, which is why there are first in the list.
			// *LANGUAGE* will be replaced with the actual language name. If not running a specific language, these paths will not be mounted
			Game_Language		citadel_*LANGUAGE*

Note

This file occasionally gets updated, so you’ll have to edit it again.

After saving the file, you can place mods in Deadlock/game/citadel/addons (create the folder if it doesn’t exist).

Mods have to be named pak##_dir.vpk where ## is a number between 01 and 99. Mods with lower numbers have higher priority. For example, if you have two model replacement mods for the same hero, the one with the lower number will be used.
