Halo: Combat Evolved Anniversary is a 2011 first-person shooter video game developed by 343 Industries, Saber Interactive, and Certain Affinity, and published by Microsoft Game Studios for the Xbox 360 console. It is a remaster of the 2001 game Halo: Combat Evolved, originally developed by Bungie. Announced at the Electronic Entertainment Expo in 2011, it was released on November 15, 2011, the tenth anniversary of Combat Evolved and the original Xbox it released on. Anniversary was later included as part of Halo: The Master Chief Collection for Xbox One in 2014, and for Windows and Xbox Series X/S in 2020.
343 Industries, an internal studio established by Microsoft in 2007, was given control over the Halo franchise after the release of Bungie's final entry, Halo: Reach in 2010. 343 Industries approached Saber Interactive to develop a remaster of Combat Evolved for the game's tenth anniversary. Saber used its proprietary game engine to reproduce the graphics and the original Halo engine for gameplay. A development tool for toggling between the old and new visuals for comparison became a feature in the shipping game. Anniversary's enhancements include a complete high-definition visual overhaul, support for cooperative and multiplayer gameplay via the Xbox Live online service, new and remastered sound effects and music, and extras such as achievements, in-game collectibles, and Kinect support.
Critical reception to Anniversary was generally positive. The updated graphics, sounds, and ability to toggle between the remastered and original visuals were praised. Complaints included technical glitches, faults with the original game's level design, and the multiplayer implementation.
