A developer has successfully ported the original Halo: Combat Evolved to run within a web browser, complete with multiplayer functionality. This technically impressive feat allows players to access the classic shooter without any downloads or installations, provided they have a stable internet connection.
The browser version is built upon a decompilation project initiated by Bnunu, with further enhancements from the Cybersecurity team. This collaborative effort has resulted in a build that supports up to 128 players in multiplayer matches and functions across Windows, Linux, and Android operating systems. Players have reported successful experiences, with one Redditor noting, "Got a couple good kills back and forth just using trackpad." The implementation includes mouse and keyboard support for a more familiar control scheme.
The project experienced a brief outage due to high traffic, triggering an automatic flag for suspected phishing, but has since been restored. Within five hours of its public release, the browser-based Halo saw nearly 20,000 games played across 115 countries, according to developer Mitchell Hynes. The project has since gained traction beyond X, with discussions and player-organized lobbies appearing on the Halo subreddit.
Multiplayer matches are currently peer-to-peer, lacking an automated matchmaking system. Players must share room links to connect with others, and a stable connection from the host is essential for a smooth experience. Despite the loading times, which may vary based on individual internet speeds, the gameplay is described as smooth, and the audio quality is preserved.
The emergence of this free, browser-based version of Halo: Combat Evolved comes shortly after Microsoft's release of Halo: Campaign Evolved. It remains to be seen how Microsoft will address this unofficial port, but for now, players can enjoy a nostalgic trip back to the Master Chief's origins directly through their web browsers.
