If you want to manually install mods for Total War: Warhammer III on Steam, you only need to place the mod pack file in the game’s data folder. Mods installed this way will show up in the basic launcher; you can use a separate mod manager for easier handling and precise load order if needed.
Updated for the Mod Manager Update (April 28, 2026): the Total War: WARHAMMER III Mod Manager got faster with large mod lists and clearer subscription and search tools, but nothing in it changes where manual mods go.

Find the game files and open the data folder
To install mods manually, begin by locating the game's installation directory through Steam.
- Opens the game’s context menu.
- Opens the install folder in File Explorer.0:30
- This is where the mod files go.
Copy the mod pack file into the data folder
Mods for Total War: Warhammer III are distributed as pack files. Placing them into the data folder is all that’s required for installation.
- Manual mods always use this file type.0:30
- Once copied, the mod functions as if installed by Steam Workshop.0:59
Use the basic mod loader
Manually installed mods will appear in the game’s default launcher, known as the CA mod loader. You do not need to unpack or extract anything further. Mods copied to the data folder are detected automatically, and you can enable or disable them from the launcher screen before starting the game.
Install and open the Warhammer 3 mod manager
For more control over mod organization and troubleshooting, you can use an external manager.
- The manager is commonly found via community links or mod sites.0:59
- Runs independently from the game launcher.
- Mod entries may not show an icon but appear by file name.1:18
Change mod load order when needed
With the mod manager, you can adjust the load order by dragging mods into different positions. This is important for mods that must override others or need to load before/after specific files, though most mods do not require a precise order. When a mod does require priority, its description will usually include instructions.
Some mods may not display an icon in the manager; this is normal and you should rely on the mod’s name to confirm it is present. Drag and drop is the usual method for changing the order. If you encounter conflicts, try changing position or disabling other mods.
What the April 2026 Mod Manager Update changed
The developer's Mod Manager Update (April 28, 2026) did not remove or replace any step above: the data folder, pack files and the drag-and-drop load order described here are not mentioned in it. It did change how the game's Mod Manager behaves, so some screens may look different from the screenshots:
- Speed with big mod lists. Mass mod activation is faster, including for very large lists, and startup is quicker with hundreds of mods installed.
- Ordering edge cases. Mod ordering and selection were improved where mods share the same pack name and/or checksum, such as a local modder version matching a subscribed one.
- Search. The filter now matches the mod title, the pack file name and the Steam Workshop mod ID.
- Subscription and version info. New icons show whether a mod is subscribed and up to date, the option to subscribe is offered for unsubscribed mods, and duplicate installed mod entries were fixed for some setups.
- Profiles. The previously used mod profile now shows immediately on startup.
The announcement does not give new load-order instructions, so keep ordering mods the way each mod's description says.
The developer warns that user-generated mods may have compatibility issues with new game updates. If you see performance or stability problems after a release, disable your mods first.
Get help with edge cases
If you encounter issues during installation or activation, or if your mod setup involves special cases not covered here, community Discord servers are valuable resources. There you can ask questions, get troubleshooting help, and find detailed instructions for mods that require more advanced steps. The guide does not name a specific website for finding mods, so for rare or “nonstandard” mods, check Discord or ask the community directly.
Community Discord servers are an excellent fallback for mod installation problems or locating rare mods. You can ask for technical advice, specific instructions, or mod sources directly from experienced players.
Also worth knowing
- Epic Games version support differs. Manual mod installation works as described for Steam, but the Epic Games version may not handle mods the same way. Some users report mods appear in management tools but do not activate, and disabling them can require extra steps.
- Mod conflicts and crashes. Running a large number of mods can cause crashes. If your game becomes unstable after 30–50 turns, consider checking your load order or reducing total mod count — the problem may be caused by conflicting mods.
- Finding mods. This guide does not specify a mod site. If you are unable to find mods on common sources like Nexus, ask on Discord or check community links for mod repositories.
Frequently asked
Where do Total War: Warhammer III mods go on Steam?
Open the game’s local files, find the data folder, and place the pack file there. After that, the mod should appear in the default CA mod loader.
What file type do I need for a manual mod install?
The mod needs to be a pack file. The file is copied directly into the data folder rather than unpacked into multiple folders.
Do I need a mod manager for Total War: Warhammer III?
No, manual installation works without one. A separate mod manager can make it easier to see mods and change load order.
Why does a mod not show an icon in the mod manager?
That can be normal. The file can still appear by name even if it is black and has no icon, and it can still be moved in the load order.
