Introduction
Helldivers 2 Companion Desktop Application and Mod Manager.
Welcome to the official Arsenal documentation. Arsenal (or HD2 Arsenal) is a desktop companion for Helldivers 2: a mod manager, a Home hub for the galactic war, and a dedicated lobby system for playing together with the same mods.
What is Arsenal?
Arsenal is built around three areas you open from the sidebar:
| Area | What it is for |
|---|---|
| Home | Featured mods chosen by the Arsenal staff, Helldivers 2 news, community videos, and live war status |
| Mod Management | Library, profiles, import, options, deploy, and launch |
| Lobby | Find or create rooms, sync a mod loadout, and drop in with other Helldivers |
You can also package mods in the Mod Builder (0.36 and later). Docs for 0.30.2 and earlier are under Legacy in the sidebar version menu.
Home
Home is the first screen after onboarding. It pulls live data from Arsenal and from Helldivers 2.
Featured Mods
A rotating showcase of mods selected by the Arsenal staff. Each entry shows artwork, title, author, and a short description. Click the main card to open the linked page (usually Nexus Mods). Thumbnails and dots let you jump between mods.
War status
The right panel tracks the galactic war.
| Tab | Contents |
|---|---|
| Top Planets | Active campaigns (liberation, defense, reclamation). Progress rates, HP, regions, and faction control. Click a planet for description, environmentals, statistics, and subfactions. |
| Major Orders | Current Super Earth orders: overview, task progress, rewards, and time remaining. Arsenal can also notify you when a new Major Order is issued. |
News and videos
The lower panel has two tabs:
| Tab | Contents |
|---|---|
| Latest News | Helldivers 2 news (updates, events, and general news). Open an item for the full article, with optional Steam and video links. |
| Community Videos | Curated Helldivers 2 videos. Click a card to watch it in Arsenal. |
Lobby
Open Lobby from the sidebar (people icon). Sign in with Discord to browse rooms, create a lobby, sync a mod loadout, and use friends and clans. The full walkthrough is in Lobby System.
