Halo: Combat Evolved Anniversary - RGH

Halo: Combat Evolved Anniversary is a first-person shooter video game set in the Halo universe and is an enhanced remake of Halo: Combat Evolved. Microsoft announced the game alongside Halo 4 at the 2011 Electronic Entertainment Expo. The game was released on November 15, 2011—the 10th anniversary of the original title's launch—for the Xbox 360 game console.

Halo: Combat Evolved Anniversary was developed as a partnership between development studios 343 Industries, Saber Interactive, and Certain Affinity. 343 Industries, the Halo series' franchise overseers, approached Saber Interactive to develop a remake of the original Halo in time for its tenth anniversary. After considering whether to remake the game entirely or to adapt and add features to the existing PC version, Saber decided to use their game engine for reproducing the original's appearance and the original Halo's engine for gameplay. A development tool for toggling between the old and new visuals became a game feature. 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 and hidden in-game collectibles. The game is the first in the series to include 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's implementation.
