- Project Reclaimer GitHub hosts official release downloads for the standalone Halo 3 PC client.
- Three downloads exist: the client, the dedicated server, and the RCON tool.
- A Steam copy of Halo: The Master Chief Collection with Halo 3 content is required.
- The client runs independently and does not modify original MCC game files.
- Always download from the official repository to avoid tampered files.
What Is on the Project Reclaimer GitHub?
Project Reclaimer is an independent fan project for Halo 3 PC players, and its official distribution channel for builds lives on GitHub at the Project Reclaimer Releases repository. Instead of a launcher-based store, the team publishes downloadable release packages that players, server hosts, and administrators grab directly from the repository's Releases page.
Only download Project Reclaimer files from the official GitHub repository or projectreclaimer.dev. Third-party mirrors are unverified and may distribute outdated or modified files.

| Project Reclaimer Client | Players | Standalone game launcher | Server browsing, joining sessions, auto-downloading content |
| Dedicated Server | Server operators | Persistent server hosting | 24/7 community servers, custom map rotations |

Requirements Before You Download
Every Project Reclaimer download assumes your PC already meets the base requirements. The project is a standalone client that works alongside your existing installation rather than replacing it.
| Requirement | Details | Notes |
|---|---|---|
| Halo: MCC on Steam | Base game installation | Purchased separately through Steam |
| Halo 3 content | Campaign and/or Multiplayer | Depends on the sessions you join |
| Windows PC | Capable of running MCC content | Same performance expectations as MCC |
| Internet access | For downloads and online play | Required for release updates and servers |
Place the Project Reclaimer client in a dedicated folder separate from your MCC installation directory. This keeps updates clean and makes troubleshooting easier.
Key facts about how the client works:
- Project Reclaimer launches directly from its own executable.
- You do not need to open the MCC in-game menu to play.
- The project does not rewrite or replace original game files.
- Steam must remain installed on the same PC for the content to be read.
Step-by-Step: Download and Install from GitHub
Follow this workflow to get from the GitHub Releases page to an active server session.
Prepare the Halo content
Install Halo: The Master Chief Collection through Steam, then install the Halo 3 Campaign and/or Multiplayer content required by the servers you want to join.
Download the latest client release
Open the official Releases page on GitHub, select the newest client build, and download the release package.
Extract to a dedicated folder
Extract or install the client into its own directory, kept separate from the MCC installation, and keep the folder accessible for future updates.
Launch and set your nickname
Start the client executable, allow network access when prompted, then open profile settings and save a recognizable player nickname.
Browse and join a server
Filter the server list by map, game type, version, or latency, select a server with an open slot, and join. Accept any required content downloads when prompted.
If a server uses custom maps or modded content you lack, the client can fetch the missing files through server-side sharing or Steam Workshop before the session starts. No manual file hunting required.
Server Operator Setup from GitHub
Server hosts use the same GitHub repository but download the dedicated server package instead of the client. The official hosting guide covers the full deployment workflow.
| Deployment Option | Best For | Focus |
|---|---|---|
| Windows | Local testing | Manual install, direct file access |
| Windows Server | Persistent hosting | Service-based operation, maintenance windows |
| Linux Docker | Containerized hosting | Repeatable deployment, isolated dependencies |
Post-Install Configuration Checklist
After the server runtime is installed, work through these configuration areas in order:
| Stage | Task | Why It Matters |
|---|---|---|
| Network | Open required ports, forward NAT | Players cannot connect without correct ports |
| Content | Add maps and mods to correct directories | Server must load content before advertising |
| Security | Set admins, anti-cheat, ban list | Protects public sessions from disruption |
| Recovery | Enable auto-restart and health checks | Server survives crashes and reboots |
| Management | Configure RCON with a strong password | Enables safe remote administration |
Restrict RCON access to trusted networks only, use a strong password, and test remote commands before relying on unattended operation. Review logs after every administrative action.
Troubleshooting GitHub Downloads
Before Asking for Help, Verify:
- MCC and Halo 3 content are installed and up to date on Steam
- The client version matches the server version you are joining
- Firewall and network access are allowed for the client
- Downloads came from the official GitHub repository
- Missing server content was accepted when the client prompted
For version issues, connectivity problems, and bug reports, the official Discord—reachable through the Project Reclaimer homepage—serves as the primary channel for development updates and feedback.
Project Reclaimer is in early development. Expect frequent releases, feature changes, and compatibility updates. Check the GitHub Releases page regularly to stay on the latest build.
FAQ
Q: Is the Project Reclaimer GitHub repository free to download?
Yes. Release packages for the client, dedicated server, and RCON tool are published on the official GitHub Releases page. You still need a purchased Steam copy of Halo: The Master Chief Collection with Halo 3 content installed.
Q: Does installing Project Reclaimer modify my Halo MCC files?
No. Project Reclaimer runs as an independent client alongside your existing installation. It does not replace or rewrite original game files, and you never need to enter the MCC in-game menu to play.
Q: What is the difference between the client and dedicated server downloads?
The client is for players who want to browse and join servers. The dedicated server package is for hosts running persistent multiplayer sessions, and the RCON tool lets administrators manage a server remotely without the in-game interface.
Q: Where do I report bugs or find Project Reclaimer updates?
The official Discord, linked from projectreclaimer.dev, is the main community channel for development updates, feedback, and issue reporting. New builds appear on the GitHub Releases page as they are published.
