The original version of Halo: Combat Evolved, released for the first Xbox in 2001, is now playable in a web browser through an AI-generated recreation. This version was created by Mitchell Hynes, who decompiled the original game and hosted it online. Hynes clarified that this browser version is distinct from the official PC port of Halo: Combat Evolved, released in 2003 by Gearbox Software. The AI-generated version reportedly achieved nearly 20,000 matches within five hours of its release, with an average of 94 frames per second. Hynes stated that his website was initially flagged as "phishing" by Cloudflare, but the suspension was quickly lifted, and he emphasized that Microsoft, the owner of the Halo franchise, was not directly involved. However, concerns have been raised that Microsoft may view the accessibility of this AI-generated version as unfair competition, especially after recently releasing Halo: Campaign Evolved on PC and consoles. The emergence of AI-generated versions of classic games has sparked debate within the industry. Some developers use AI tools like Claude to create "mods" more efficiently, while others produce clones of well-known games, leading to conflicts with original creators. For example, the creator of an AI-generated fangame Fallout: New York removed the project after receiving a cease-and-desist letter from Bethesda. Microsoft has shifted its Halo development to Activision, the company behind Call of Duty, and has dissolved Halo Studios. The future of Hynes' AI-generated version of Halo: Combat Evolved remains uncertain, as legal challenges from publishers could impact its availability.
