HD2 Modding on Linux

Introduction

This is a walkthrough on how to get various modding tools to work on Linux by using Steam and Proton.
I'm assuming you have a cursory knowledge of filesystems and unzipping files.
These are not the only methods that work! There are a few ways to get this running, but these are the ways that worked for me.

Helldivers 2 Mod Manager - HD2MM - (GitHub)

  1. Download HD2MM and unzip it somewhere
  2. Open Steam and add HD2MM as a non-Steam game
    1. All the way at the top, click Game --> Add a Non-Steam Game to my Library --> Browse
    2. Navigate to wherever you unzipped HD2MM and select the .exe
  3. Setup Proton for HD2MM
    1. In your Steam Library, right click HD2MM
    2. Click Properties (This is where you can give it a cute name :3)
    3. In the menu on the left, click Compatibility
    4. Click Force the use of a specific Steam Play compatibility tool
    5. Select a Proton version (I use GE-Proton because that's what I use for the game itself)
  4. Launch HD2MM through Steam
At this point, the HD2MM window should appear and work as it does on Windows. The only difference is the file pathing.

From this point on, follow the regular guides on how to use HD2MM.

HD2 Community SDK for Blender

When running Blender natively, trying to add the SDK will throw a missing HDTool_Helper error.
All releases of Blender can be found here, but you don't need that for this method.
  1. Install Blender through Steam
    By default, this will install v4.4, which is not compatible with the SDK. Rollback to v4.0 by:
    1. In your Steam Library, right click Blender
    2. Click Properties
    3. In the menu on the left, click Betas
    4. In Beta Participation, open the dropdown and select "v4.0 - Stable"
  2. Setup Proton for Blender
    1. In your Steam Library, right click Blender
    2. Click Properties
    3. In the menu on the left, click Compatibility
    4. Click Force the use of a specific Steam Play compatibility tool
    5. Select a Proton version (I use Proton 9.0-4 for no reason)
  3. Open Blender through Steam and follow the HD2 Modding Guide: Workspace Setup section
