How to Install Custom Skin Mods in Deadlock

Mods are allowed in matches and won't get you banned, as long as they do not provide an unfair advantage.

Manual Installation

1. Locate Your Deadlock Installation Folder — Open Steam, right-click Deadlock → Properties → Installed Files → Browse.
2. Modify gameinfo.gi for Mod Support — Navigate to /game/citadel, edit gameinfo.gi, and replace the FileSystem and AddonConfig section (lines 23–58) exactly as follows:

   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*
   
   		Mod                 citadel
   		Write               citadel
   		Game                citadel/addons
   		Game                citadel
   		Mod                 core
   		Write               core
   		Game                core
   		AddonRoot           citadel_addons
   		OfficialAddonRoot   citadel_community_addons
   	}
   }
   AddonConfig
   {
   	"UseOfficialAddons" "1"
   }

3. Add Your Custom Mods — Create an addons folder in /game/citadel. Download .vpk files from Deadlocker.net or GameBanana and place them inside.
4. Naming Conventions for Mod Files — Name files pak01_dir.vpk, pak02_dir.vpk, etc. Change the number (01–99) if you have conflicts.
5. Open Deadlock and Enjoy the Mods — Launch the game; mods load automatically.

Deadlock Mod Manager (Recommended)

Download the Deadlock Mod Manager from deadlockmods.app. On first launch it detects your game directory automatically. Go to the Mods tab, find a mod, and click Download — no manual file management needed.
