- Project Reclaimer install requires Steam's Halo: The Master Chief Collection with Halo 3 content installed first.
- The standalone client launches directly and does not modify or replace your original MCC files.
- Download releases only from the official GitHub releases page or projectreclaimer.dev.
- Set your nickname before joining any server so friends and admins can find you.
- Servers missing content will trigger automatic mod downloads when you connect.
What You Need Before Installing Project Reclaimer
Project Reclaimer is a standalone Halo 3 PC fan project — an independent launcher and server browser that runs alongside your existing Steam installation of Halo: The Master Chief Collection. It is not an official Microsoft, Xbox Game Studios, or Halo Studios product. Before you install anything, confirm your system meets the base requirements.
Project Reclaimer does not include Halo 3 game files. You must own and install Halo: The Master Chief Collection on Steam, with the Halo 3 Campaign and/or Multiplayer components installed, before the client can launch sessions.
| Requirement | Details | Required? |
|---|---|---|
| Halo: MCC (Steam) | Base game installation via Steam | Yes |
| Halo 3 Multiplayer | Needed for multiplayer and Forge sessions | For multiplayer |
| Halo 3 Campaign | Needed for campaign and co-op sessions | For campaign |
| Windows PC | Capable of running installed MCC content | Yes |
| Internet access | For downloads, server browsing, online play | Yes |
Three download builds are published on the official releases page, and each serves a different audience:
Client (Players)
- Standalone game launcher
- Server browser and mod downloads
- For joining public and private sessions
Dedicated Server
- Persistent server hosting
- Custom maps and modes
- For community server operators
RCON Tool
- Remote administration
- Manage players without the game client
- For administrators
Project Reclaimer Install: Step-by-Step Process
The full Project Reclaimer install takes most players under 30 minutes, with most of that time spent downloading MCC content if it is not already present. Follow the sequence below in order — skipping the Steam step is the single most common cause of launch failures.
Install Halo content on Steam
Install Halo: The Master Chief Collection through Steam, then add the Halo 3 Campaign and/or Halo 3 Multiplayer components you plan to play. Keep Steam installed and signed in on the same PC.
Download the latest client release
Get the current Project Reclaimer client from the official GitHub releases page. Always use the latest version — older clients may be incompatible with updated servers.
Extract to its own directory
Place the client in a dedicated folder separate from your MCC installation. This keeps updates clean and avoids file conflicts. Preserve the release's folder structure.
Launch the standalone client
Run the Project Reclaimer executable directly. You do not need to open the MCC launcher or enter the MCC in-game menu first. Allow network access when prompted and wait for the server list to load.
Set your nickname
Open the profile or account settings, enter a recognizable player name, and save. This is the name shown in sessions and server lists.
Join your first server
Use the server browser to filter by map, game type, version, or latency, select a server with an open slot, and connect. Accept any content downloads the server requires.
Because Project Reclaimer does not modify original game files, you can safely remove the client by deleting its folder. Your MCC installation stays untouched throughout.
Using the Server Browser After Install
Once the client is running, the server browser becomes your main hub. Each filter tells you something different about a session before you commit to joining.
| Filter | What It Shows | How to Use It |
|---|---|---|
| Map | The active map or environment | Pick familiar arenas or discover custom maps |
| Game Type | The ruleset or mode | Check rules match your expectations first |
| Version | Client compatibility info | Update your client if servers require newer builds |
| Mods | Custom content in use | Accept downloads when prompted before joining |
| VPN | Network path indicator | Try a different server if connections fail |
| Latency | Network response time | Prefer lower latency for responsive play |
When a server uses maps, Forge creations, or mode scripts you do not have, the client can obtain the missing files automatically — through the server itself or supported Steam Workshop workflows. Confirm the download, wait for it to finish, and reconnect if prompted.
You can also join friends through a shared server address or a Discord invitation when the server is configured for it, using the same client workflow.
Common Install Problems and Fixes
Most first-run issues trace back to one of a handful of causes. Work through this table before seeking help on the official Discord, which serves as the project's main support and update channel.
| Problem | Likely Cause | Fix |
|---|---|---|
| Client will not launch | Missing Halo 3 content in MCC | Install Halo 3 components via Steam |
| Empty server list | Firewall blocking network access | Allow the client through your firewall |
| Cannot join a server | Client version mismatch | Download the latest release from GitHub |
| Stuck on download | Large server-side mod files | Wait; verify connection and retry |
| Server unreachable | VPN/network path restriction | Try a non-VPN connection or another server |
| Name not saving | Settings not saved before joining | Save nickname in profile settings first |
Avoid third-party mirrors and re-uploads. The only confirmed download sources are the official website and the project's GitHub releases repository. Unofficial copies may be outdated or unsafe.

Project Reclaimer Install FAQ
Q: Does Project Reclaimer modify my Halo: MCC installation?
No. Project Reclaimer runs as an independent client alongside your existing Steam installation. It does not replace or rewrite original game files, and deleting the client folder removes it cleanly.
Q: Do I need to open the MCC launcher to play?
No. You launch the Project Reclaimer client directly. Keep Steam installed and signed in, but you never need to enter the MCC in-game menu to join a session.
Q: Is Project Reclaimer free to download?
The client is distributed through the project's official GitHub releases page. You still need to own Halo: The Master Chief Collection on Steam with the relevant Halo 3 content installed.
Q: Where do I get help if the install fails?
The official Discord, linked from projectreclaimer.dev, is the project's main channel for development news, bug reports, and installation support. You can also check the official How to Play guide at projectreclaimer.dev/play.
