Boot Mod Loader v0.13.4

Requires HD2 Mod Setting GUI 1.12.0 or newer for the settings of mods made for Mod Options Menu and Mod Bindings Menu.

• 0.13.4: The game update of 2026-10-29 (Steam build 26251122, stingray:46805 437a3d44…) is a checked game version. Its boot script was extracted from the install and is byte for byte the one embedded here, so the log no longer says NOT THIS GAME VERSION on it.
• 0.13.3: A mod whose inner functions check a variable of their own named chef is still recognised as made for Chef Shared Loader and handed to it (HUDdle 0.4.9). Checks in comments and strings do not count either.

Install with your mod manager like any other mod. Log: %APPDATA%\Arrowhead\Helldivers2\boot_mod_loader.log.

Boot Mod Loader v0.13.2

Requires HD2 Mod Setting GUI 1.12.0 or newer for the settings of mods made for Mod Options Menu and Mod Bindings Menu.

Other loaders and boots

• 0.13.0–0.13.2: Mods made only for Chef Shared Loader are handed to Chef when it is installed (its documented hand-off for other loaders), instead of failing here. Chef's core is read from its deployed archive, starts only those mods, and runs as one named link of the update, render and shutdown chain, so per-mod timers measure the mods below it. Checked with Chef Shared Loader 1.2.1 in game.
• 0.12.0–0.12.1: A mod that ships its own boot but is not a loader (such as Objective Tracker 0.6.7) runs as a guest when the mod manager has moved its boot aside (HD2 Mod Quick Deploy does this). Each guest runs under its own name, guest_boot/<mod name>.

The game still runs only one boot: Boot Mod Loader's must be the one in the highest patch. See the README, "Other loaders and boots".

Install with your mod manager like any other mod. Log: %APPDATA%\Arrowhead\Helldivers2\boot_mod_loader.log.

Boot Mod Loader v0.11.0

Requires HD2 Mod Setting GUI 1.12.0 or newer for the settings of mods made for Mod Options Menu and Mod Bindings Menu.

• 0.11.0: Translations from translation packs follow the game's language setting in the settings window (tag "game").
• 0.10.0: Translation packs made for Mod Options Menu also translate mods that use their own list in the settings window. The loader passes such a mod's settings through the pack once a launch, registers nothing, and writes the translated texts as <name>_translations.json.
• 0.9.0: Mod Options Menu's limit of 32 options per mod (and 112 mods, 36 key slots) no longer applies; a guard of 1000 remains.
• 0.8.0: A mod that supports both the settings window and Mod Options Menu uses the window from its second launch on; its settings carry over. If it writes no list of its own within 10 s, the menus come back and are not hidden from it again.

Install with your mod manager like any other mod. Log: %APPDATA%\Arrowhead\Helldivers2\boot_mod_loader.log.

Boot Mod Loader v0.7.0

Requires HD2 Mod Setting GUI 1.10.1 or newer for the settings of mods made for Mod Options Menu and Mod Bindings Menu.

• 0.7.0: A mod that lists its settings for the settings window itself (such as ActionCam 3.0) now uses its own settings in the window instead of a duplicate Mod Options Menu list. The menus answer api as nil to it; a setting it registers anyway is served from its own settings file.
• 0.6.0: Settings lists of mods that no longer register their settings are set aside (.stale), so the window shows only current settings.
• 0.5.0: Mods made for Mod Bindings Menu get their keys back: set them in the settings window, outside the game. A mod manager icon (0.5.1).
• 0.4.0: Spaces between Mod Options Menu rows (gap) are kept in the window.

Install with your mod manager like any other mod. Log: %APPDATA%\Arrowhead\Helldivers2\boot_mod_loader.log.

Boot Mod Loader v0.3.6

Mods made for Mod Options Menu get their settings back: they show in HD2 Mod Setting GUI (1.8.0 or newer) outside the game, and the settings you had made in Mod Options Menu carry over.

Boot Mod Loader v0.2.0

Adds on_shutdown(fn) for work that must run last on quit, and logs NOT THIS GAME VERSION on a game build it was not checked on (checked: 25988413, 26088801).

Boot Mod Loader v0.1.0

First release. For Steam build 25988413 (the 2026-10-20 update). Replaces the game's boot script, runs the original first, and starts every Lua mod whose first line is -- HD2-Addon: mods/<author>/<name>. Only one mod can replace boot: do not install another loader that does. Mods that need LuaJIT (ffi, bit, goto) do not work on this game; the log (%APPDATA%\Arrowhead\Helldivers2\boot_mod_loader.log) says which failed and why.
