Description
Echelon keeps every Helldivers 2 mod you download in one library, lets you sort them into profiles (think loadouts for your mods) and puts a whole profile into the game with one click. When you want a clean game again, one more click takes every mod back out.

Echelon is free, and every feature is for everyone. Nothing is locked.

Installation
  1. Download Echelon-Setup.exe and run it. It installs for your user only, so no admin rights are needed.
  2. The installer is code-signed. Windows may still say "Windows protected your PC" for a while, because the signature is new. Click More info, then Run anyway.
  3. The first-time setup finds your game folder, asks you to accept the licence, and asks which online extras you want (all of them start off).
  4. Coming from HD2 Arsenal? Setup offers to bring over your mods, profiles, load order, separators, tags and option choices. Arsenal's own files aren't changed.
Updating: download the new installer here and run it over the old one. Your mods, profiles and settings stay where they are. If you turn on update checks in the setup or in Settings, Echelon shows an Update button when a new version is out. It only downloads when you click it, and it checks the download against its SHA-256 checksum first.

Checking your download: open a command prompt in the folder with the installer and run
Code:
certutil -hashfile Echelon-Setup.exe SHA256
The result should match the number in the .sha256 file.

Main features
  • Library: every mod as a picture card or in a compact list, with a details panel showing its description, options, size, which profiles use it, and its web page.
  • Profiles: load order, separators, tags and per-mod options. Switch between loadouts in a second.
  • One-click Deploy and Purge: Deploy puts exactly the open profile into the game. Purge takes every mod out, including ones installed by hand or by other tools.
  • Mod options: pick versions, colours and extras. Mods that ship their variants as folders get proper options too, and all-in-one packs get a switch per part.
  • Updating mods: when you add a newer version of a mod you already have, Echelon offers to replace the old one and keeps your option choices.
  • Bingus Shared Loader support: Echelon recognises the loader and the mods that need it, warns when a profile is missing it, and keeps the loader locked in the right spot so Bingus mods start.
  • Clash and load order checks: see when two mods change the same thing, which one wins, and which mods are completely hidden by others.
  • Game Folder Check: tells you if a game update or Steam's "Verify integrity" removed your mods.
  • Crash Finder: when the game crashes with mods on, it tests half of your mods at a time until it finds the one to blame.
  • Import from HD2 Arsenal: if a mod came as several versions without a manifest, Arsenal kept only the one picked back then. Echelon lists those mods under Check options so you can get the full download and choose again.
  • Share profiles as a short code (EC-XXXX-XXXX) or a link. Friends see exactly which mods they're missing.
  • Solo-only mods: some Lua mods change the game for everyone in the lobby. Mark them as solo only and they get a SOLO badge, plus a reminder to turn them off before public lobbies when you deploy.
  • Developer Suite for mod authors:
    • Mod Builder: build a mod with options and a manifest without writing any JSON.
    • Repatcher: keeps your own model and text mods working after a game update. Mods that need it get a NEEDS REPATCH badge.
    • Mod Inspector: see what's inside your mod, check it for common problems, and compare versions.
    • Retagger: a shortcut to HD2 Retagger by soulls00 for moving an armor look onto other armors. You get it from soulls00; Echelon only starts it.
    The Repatcher and Mod Inspector are for your own mods. Before they open a mod, they ask you to confirm it's yours or that its author allows it.
  • Languages: English, Simplified Chinese and Japanese.

Requirements
  • Windows 10 or 11 (64-bit).
  • Helldivers 2. Echelon finds the game folder automatically, or asks you to point to it.
  • No other mods or tools needed, and no account: Echelon has no sign-in of any kind.

FAQ
Can I bring my mods over from HD2 Arsenal?
Yes. The first-time setup offers to import your mods, profiles, load order, separators, tags and option choices. To do it later, click the + button above the profile list and choose Import from Arsenal.... If Echelon can't find Arsenal's data (for example after you moved it), it lets you pick Arsenal's hd2a_data.json file yourself. Nothing in Arsenal is changed.

Can I go back to Arsenal, or use both?
Yes. Both put mods in the same game folder, so use one at a time: click Purge in the one you're leaving, then deploy from the other. When Echelon deploys, it clears every mod from the game folder first, so it never stacks on top of what another manager put there. The other manager may still show its mods as deployed until you purge there.

Can I download mods straight into Echelon?
Almost. Copy a mod's page link and press Ctrl+V in Echelon (or use Add mod > From a link). Echelon opens the page in your browser. Download the file there as usual, and Echelon picks it up from your Downloads folder and adds it, asking first when it can't tell which mod the file is. It also remembers the mod's web page. There's no one-click button, because Echelon doesn't sign in to any mod site. Direct links from Google Drive, Dropbox, GitHub and Discord are downloaded straight in.

Can it check for mod updates?
Not automatically. To check by hand, each mod shows the version you have, and right-click > Open web page takes you to its page (select several mods to open all their pages at once). When you add the new download, Echelon spots that it's an update and offers to replace the old one, keeping its place, tags, web page and option choices.

Does it go online?
Only if you turn it on. The update check for Echelon itself, translating mod descriptions, and sharing profiles are all off until you choose them. No accounts, no tracking, no ads.

What does Echelon do about mods with Lua scripts?
It tells you. Mods that contain Lua get a LUA badge and a notice when you add them. Some Lua mods change the game for everyone in the lobby, so you can mark those as solo only and Echelon reminds you before you deploy them. What you install is your choice: Echelon doesn't judge or block mods, and nothing about your mods is sent anywhere.

Why can't I move HD2 SmoothBoot below the Bingus loader?
It's already where it needs to be. Echelon keeps the Bingus loader as the very last mod and puts SmoothBoot directly above it, after every other Bingus mod. That gives the same result as placing it "below Bingus" in other managers, so you don't need to move it. To bring scattered Bingus mods together, right-click the Bingus section and choose Gather Bingus mods here.

The text is hard to read. Can I make it bigger?
Yes: Settings > Appearance > Text size, from 80% to 150%.

How do I see mod descriptions in my language?
Settings > General
: pick your language under Interface language, then tick Translate mod descriptions and options into the interface language. With the interface in English, this translates mods written in Chinese, Japanese, Korean or Russian. It uses the free MyMemory service, so it stays off until you turn it on.

How do I put a mod into another profile?
Inside a profile, click the ⋮ on a mod and choose Copy to profiles.... It works with several mods selected. When you add new mods, Echelon asks which profiles they go into; if it doesn't, tick Ask which profiles when adding mods at the top of the Library page.

Does it work on Linux?
There's no Linux version, but users report the Windows version running through Proton: open protontricks, pick Helldivers 2, choose "run arbitrary executable" and run the Echelon installer, then start Echelon from its install folder inside the game's prefix. The Start game button doesn't work there, so launch the game from Steam. If you use the Linux version of HD2 Arsenal, Echelon looks for its data by itself when you import. This is community-tested, not official.

My antivirus flagged it.
Some antivirus programs flag apps built with Python by mistake, and it can happen again with a new version. Check the installer against its .sha256 file, and post in the discussion thread with the antivirus name so it can be reported as a false positive.

Will it mess up my mods or my game?
Echelon never edits your mod files in place. It keeps its own copy of each mod. Deploy only touches mod files in the game's data folder, and Purge takes them all out again.

Something went wrong. How do I report it?
Post in this page's discussion thread and attach your latest log from %APPDATA%\Echelon\logs. Settings > System > About shows the exact path.

That's what I thought. lol but for some reason it wouldn't let me. Restarting the application fixed it though. But yes - adding an option so you're able to go ahead and place the mod/s into a user created group after or during the "Add to Profiles" window. Like I said - it'd save just a few measly seconds. I was just wondering. Regardless, thanks for making a solid alternative manager.
Glad a restart sorted it! If dropping ever stops working again, let me know how you opened Echelon that time (from the installer, a shortcut, etc.), since that might explain it.

And picking a separator right in the "Add to profiles" window is a nice idea. Small, but it adds up when you're adding a lot of mods. I've put it on my list. Thanks for the kind words, and for giving Echelon a try!

You can just change the mods location instead to the portable hard drive.

You do that by pressing on Settings (the cog icon) > System > Press on "Run first-time setup again" under the "Setup and Legal" section. Go through it until you reach the "Where your mods are kept". Here you can choose the folder and drive where you want your mods to be kept.
I see, in that case, have you tried navigating to Settings and then the "Directories" tab? You can specify where your mod loader should look for mod storage, temporary storage and logs. You should be able to do so on both PCs. If the settings don't save between swaps, you should report back here, because that sounds like it would be a bug.
I thought about it for a moment, and I don't know if you misunderstood my meaning. What I actually want to say is that I need to import the mod again after changing my computer. The mod exist in the form of a folder after installation, but the selection in the mod folder is presented by numbers, which is very troublesome.I set the mod storage folder on the mobile hard drive in Arsenal Manager, I can directly copy and paste log files without having to import the mod again.

Thanks Sheiqaa and Amiba for jumping in! Yukamizi, your mods are safe, they're all still on E:. The catch is that Echelon only moves the mod files there. Its list of mods, your profiles and your settings stay on each computer, in %APPDATA%\Echelon, so the desktop saw an empty library.

For now you can carry it over by hand:
1. On the laptop, click Purge, then close Echelon.
2. Close Echelon on the desktop too.
3. Copy the whole %APPDATA%\Echelon folder from the laptop and paste it over the one on the desktop.
4. Make sure the portable drive is E: on both computers, then open Echelon on the desktop. If it asks for the game folder, point it there.

You'd need to copy that folder again after changing things on one computer. A proper "everything on the portable drive" mode is a good idea, and I've added it to my list. Also convenient for me because I have a desktop/laptop setup as well.
Okay, I'll try it out next time. Thank you

Thank you for your help. The problem has been roughly solved.

Open %LOCALAPPDATA%\hd2arsenal\hd2a_data.json in Notepad, search (Ctrl+F) for "nexus" and copy the few lines around the first match, the part that looks like "nexusData": { ... }. Leave out anything with a folder path, since those include your Windows user name. Post it here, or in the bug forum on the Discord if you'd rather.
Every mod has a "nexusData" entry like this:
Code:
"tags": [...],
"nexusData": {
  "modId": "6882",
  "fileId": "65445",
  "version": "0.9.50",
  "updateTimestamp": 1789782485
},
"options": [...],
For reference, that snippet is for KoabraFang's Unofficial HD2 Patches UHD2P.
The "modId" entry should be the relevant part to resolve the Nexus page link, like https://www.nexusmods.com/helldivers2/mods/["modId"].
Also, manually installed mods will have their "nexusData" entry set to null, like this:
Code:
"nexusData": null,

Can be add two deployment methods: symbolic links and hard links?
This can reduce disk writes and also make deployment faster.

Thanks for the idea! Hard links make a lot of sense here. Echelon already uses them when importing from another mod manager on the same drive, so using them for deploying too is a natural next step: when your mod storage and the game are on the same drive, Echelon would link the files instead of copying them, and fall back to copying when they aren't. I've added it to the list.

Symbolic links are less likely, since Windows only allows them with admin rights or Developer Mode turned on, and hard links give the same savings without that.

so uh, the 36.2 apparently allows you to launch the game through the launcher, but I was able to do so on 36.1

EDIT: not sure if Important, but I did install it inside of HELLDIVERS prefix (also, had to install 7zip and place it inside echelon install for it to detect it and work) the auto-updates don't work but I can just download a new .exe and install it using protontricks and it works

Thanks, this is really helpful! A few questions so I can fix the Linux side properly:

1. Does Start game still work for you on 0.36.2? It worked on 0.36.1 because you run Echelon in the game's own prefix, but 0.36.2 changed how it asks Steam, so I want to make sure it didn't break for you.
2. Which 7-Zip did you install: the Linux package, or the Windows 7-Zip through protontricks? And did you copy 7z.exe (and 7z.dll) into Echelon's folder? I'll make Echelon look there by itself in a future update.
3. When you press Update, what happens: an error, nothing, or does the installer start and fail? If you can, send the log from that session. Settings > System > About shows where it is ("This session's log").

A native Linux version (AppImage) is planned for the 0.37 series too, which should make all of this simpler.

im a bit out of the loop and only heard tiny bits and pieces about it, but what's the reason for this mod's existence and people nudging to switch away from arsenal? is arsenal or its devs doing something controversial that an alternative became a demand?
