Adding Mods

Arsenal supports multiple methods for adding mods to your collection. Choose the method that best fits your workflow.

Arsenal Add Mods Dialog

Folders

Best for mods you’ve manually downloaded and extracted.

  1. Click the Add Mod button
  2. Select Folders from the dialog
  3. Browse to the folder containing mod files
  4. Select one or more folders with .patch_0 files
  5. The mods are added to your library

Folder Structure Requirements

The selected folder should contain patch files directly or in subfolders:

MyMod/
├── manifest.json          # Optional
├── something.patch_0
├── something.patch_0.gpu_resources
└── something.patch_0.stream

Or with options:

MyMod/
├── manifest.json
├── Option1/
│   └── *.patch_0
└── Option2/
    └── *.patch_0

Files

Best for freshly downloaded mods from Nexus Mods or other sources.

  1. Click the Add Mod button
  2. Select Files from the dialog
  3. Select .zip, .rar, or .7z archive files
  4. Archives are extracted and processed automatically

Supported Archive Formats

FormatExtension
ZIP.zip
RAR.rar
7-Zip.7z

Drag and Drop

The fastest method for quick imports.

Simply drag archive files or folders directly onto the mod list area. Arsenal will:

  1. Detect the dropped items
  2. Extract archives if necessary
  3. Process and add the mods
  4. Show a notification when complete

Nexus Mods (NXM Protocol)

Download directly from Nexus Mods with one click.

Usage

  1. Browse mods on Nexus Mods 
  2. Click any Mod Manager Download, Vortex, Arsenal button
  3. The download is automatically added to Arsenal’s queue
  4. Once complete, open the Download Panel to install

Note: The Mod Manager and Vortex buttons are optional, and mod developers may decide not to include these buttons on their mod page. To work around this limitation, the Arsenal Browser Extension ensures there is always a button available, allowing users to download any Helldivers 2 mod through the NXM protocol by adding a button alongside the manual download options.

  2. Check the mods you want to add (already-added mods show a green checkmark)

Troubleshooting

”No patch files found”

The selected folder doesn’t contain valid Helldivers 2 mod files. Ensure you’re selecting the correct folder level containing .patch_0 files.

Note: Reshade mods are not supported.

Archive extraction failed

  • Ensure the archive isn’t corrupted
  • Check that you have sufficient disk space
  • Try extracting manually and using the Folders method

Mod appears but has no options

Not all mods have configurable options. Only mods with a proper manifest.json defining Options will show the options button enabled.
