Project Reclaimer Adds 128-Player Multiplayer and Forge Tools to Halo 3 on PC
A community-built launcher for Halo: The Master Chief Collection enables massive multiplayer matches, expanded modding, and dedicated servers for PC users.

Key points
- Project Reclaimer allows up to 128 players in Halo 3 multiplayer matches on PC.
- The launcher adds sixteen-player campaign co-op and four-player online split-screen capabilities.
- Forge tools are expanded with cross-map objects, custom lighting, and placed AI enemies.
A community-developed launcher named Project Reclaimer has introduced support for one hundred and twenty-eight player multiplayer matches in Halo 3. According to Windows Central, this PC-specific tool runs directly off existing installations of Halo: The Master Chief Collection, requiring users to own the base game.
The project enables sixty-four-on-sixty-four team battles with full mod support. Windows Central reports that the initiative also restores the original Halo 3 menu interface and includes a server browser for easier match discovery. This functionality represents a significant expansion of the game’s original capabilities.
Expanded Gameplay and Modding Features
Beyond large-scale multiplayer, the launcher supports sixteen-player cooperative campaign play. Windows Central notes that players can bring customized Spartans or Elites into these sessions. Additionally, four-player split-screen functionality has been restored, allowing local groups to play together online via community servers rather than being restricted to a local network.
Forge tools have been significantly enhanced to allow greater creative freedom. According to Windows Central, creators can now use objects from different maps, remove invisible boundaries, and adjust custom lighting. Users can also place various Halo 3 AI factions, including Spartans, Elites, Marines, Grunts, Jackals, Brutes, and Hunters, into their custom maps to fight players or each other.
Platform Limitations and Server Infrastructure
The updated experience is currently available only on PC, which Windows Central describes as a limitation for console users. The platform supports dedicated servers running on Windows or Linux operating systems. These servers feature playlists where players can vote on subsequent maps and game modes, facilitating community-driven matchmaking.
Mods are handled automatically when joining a server, eliminating the need for manual file hunting. Windows Central highlights this feature as a significant quality-of-life improvement, comparing the ease of use to experiences found in other community-driven gaming platforms. The project effectively builds a comprehensive multiplayer platform around a title that originally released nearly two decades ago.
What should you do?
Users interested in these features must own Halo: The Master Chief Collection on PC. Windows Central confirms that the launcher runs directly off this existing installation. Players should verify their system meets the requirements for running dedicated server software or joining large-scale matches.
