How to Install Mods

Manual Approach

If you prefer a hands-on approach, follow these steps to manually install mods:

  • Start by downloading the mod you want to install. Mods typically come in compressed archive formats like .rar or .zip.
  • Use software like WinRAR or 7-Zip to extract the contents of the mod archive.
Distribution Path
Steam You can place the mod folder anywhere on your PC
Windows Store C:\Users\YourUsername\AppData\Local\Packages\Microsoft.BulldogThreshold_8wekyb3d8bbwe\LocalState
  • Open the extracted mod folder and locate the ModData folder. Copy the address/path of this folder (or the mod folder itself if ModData isn’t present).
  • Navigate to C:\Users\Username\AppData\Local\Halo Wars and create a new text file named ModManifest.txt. Paste the copied address/path into this file.
  • Save the ModManifest.txt file, and you’re done! The mod is now installed and ready to use.

Using Firebase Mod Manager

Follow these steps to install mods using Firebase

  • Start by downloading the mod you want to install. Mods compatible with Firebase will typically have a ModData folder.
  • Use software like WinRAR or 7-Zip to extract the mod archive.
  • Download and install Firebase
  • Move the mod folder into the HWDEMods folder located in Firebase’s directory.

When closing Firebase, use the [X] in its window. Closing it via the taskbar or Alt+F4 may leave it running in the background, preventing relaunch until it’s ended in Task Manager.

How to Uninstall Mods

Manual Approach

To uninstall mods manually:

  • Delete the ModManifest.txt file, and the game will no longer load the mod.

Using Firebase Mod Manager

Uninstalling mods with Firebase is straightforward:

  • Open Firebase and navigate to the “My Mods” section.
  • Click “My Mods” to open your file explorer to the mod directory.
  • From there, delete any installed mods you no longer want.
  • You can also revert to the unmodified game by selecting the “Vanilla” option inside Firebase.
