- Project Reclaimer Hugegrass refers to community custom-map content played through the standalone Halo 3 PC launcher.
- Server browser filter: Use map and mod tags in the browser to find custom-map servers quickly.
- Automatic downloads: The client fetches missing custom maps and mode files when you join a server.
- Forge publishing: Custom maps can be shared via server-side hosting or supported Steam Workshop workflows.
- No MCC menu needed: Project Reclaimer runs as an independent client alongside your Steam MCC installation.
Project Reclaimer Hugegrass: What It Covers
Project Reclaimer Hugegrass is the community shorthand for custom multiplayer map content — community-built environments such as Hugegrass-style layouts — running on Project Reclaimer, the standalone Halo 3 PC fan project. Project Reclaimer is built around a server browser, expanded Forge, dedicated servers, campaign co-op for up to 16 players, and automatic mod downloads for players who join modded sessions. It is a fan project, not an official Microsoft, Xbox Game Studios, or Halo Studios product.
The key point for custom-map players: you rarely need to hunt down files manually. Servers advertise the maps and modes they run, and the client obtains missing content when prompted.
| Feature | What It Means for Custom Maps |
|---|---|
| Server browser | Filter sessions by map, game type, version, mods, and latency |
| Server-side sharing | Client downloads required map files automatically on join |
| Steam Workshop | Subscribe to supported custom content for easy updates |
| Expanded Forge | Build, freeze, and edit large-scale custom map layouts |
| Max 128 players | Large-battle servers can run custom map rotations |
Filter the server browser by mod tag first, then by map name. This surfaces custom-map sessions — including Hugegrass-style community maps — in one pass.
Step-by-Step: Joining a Custom Map Server
Install the base game
Install Halo: The Master Chief Collection on Steam and make sure the Halo 3 Multiplayer content is downloaded.
Get the Project Reclaimer client
Download the latest client from the official releases page and place it in its own folder, separate from MCC.
Launch the standalone client
Start Project Reclaimer directly. You do not need to open the MCC menu, and original game files are not modified.
Set your nickname
Open profile settings, enter a recognizable player name, and save before joining.
Filter and join
Filter the server list by map, mode, version, and latency, then join. Accept the download prompt if the server requires custom content.
If a server reports a newer Project Reclaimer version than your client, update from the release page before connecting to avoid failed joins.
How Custom Content Is Distributed
Custom maps, campaign mods, Forge creations, and mode scripts flow to players through two main channels: server-side sharing and Steam Workshop. When you join a server running content you don't have, the client handles the download before the session starts.
Map Mods
- Custom arena layouts
- Community multiplayer environments
- Server-specific map rotations
Forge Creations
- Player-built arenas
- Objective-focused layouts
- Shared via servers or Workshop
Mode Scripts
- Custom objectives and rules
- JSON configuration and Megalo logic
- Auto-downloaded with the session
| Content Type | Distribution Method | Player Action |
|---|---|---|
| Custom maps | Server-side sharing / Workshop | Accept download prompt on join |
| Campaign mods | Workshop or session transfer | Ensure compatible content installed |
| Forge maps | Server sharing or Workshop | Join through normal server browser |
| Mode scripts | Bundled with server session | No manual setup required |
If a download stalls or the session requests a restart, disconnect, verify the client is current, and rejoin — the server will re-offer missing files.
Building Your Own Hugegrass-Style Map in Forge
Project Reclaimer's expanded Forge adds frozen-object editing, larger construction options, AI-related elements, and object sources labeled STOCK, BUILT-IN, and MOD. The core workflow for a custom map:
| Stage | Focus | Key Check |
|---|---|---|
| Setup | Choose base map, enter editor | Confirm map and mode before long sessions |
| Layout | Place structures, spawns, scenery | Keep paths and sightlines readable |
| Large builds | Freeze sections, move big objects | Test collision from player perspective |
| Gameplay | Add spawns, objectives, AI elements | Change one variable at a time |
| Validate | Save, reload, confirm persistence | Reload before inviting testers |
| Test | Multiplayer session with friends | Test in the intended game mode |
Save separate iterations for major layout changes, then publish through server-side hosting or a supported Workshop workflow so other players can join without manual file hunting.
Preparation Checklist
Before Joining or Hosting Custom Maps:
- Halo 3 Multiplayer installed through Steam MCC
- Latest Project Reclaimer client installed
- Nickname set in profile settings
- Server browser filters configured (map, mode, latency)
- Steam Workshop subscriptions up to date
FAQ
Q: Do I need to manually download custom maps like Hugegrass-style content?
Usually not. Project Reclaimer servers can share required files, and the client downloads missing content when you join. Some creators also publish supported content through Steam Workshop subscriptions.
Q: Does Project Reclaimer modify my Halo: The Master Chief Collection installation?
No. Project Reclaimer runs as a standalone client alongside your Steam installation. It does not replace or rewrite original game files, and you do not need to enter the MCC in-game menu.
Q: Is Project Reclaimer an official Halo product?
No. It is an independent fan project for Halo 3 PC players and is not affiliated with Microsoft, Xbox Game Studios, Halo Studios, or Bungie.
Q: Can I test my custom Forge map with friends?
Yes. Save and reload the map first, then host or join a multiplayer session using it. Test spawning, objectives, boundaries, and performance with multiple players in the intended game mode.
