Content Update 29 (“CU29”) brings a new Arena map, a Covenant object palette and new Forge features, a new armor core and customization rewards, and the first of three free Operations—starting with the Halo Wars-themed “Spirit of Fire.” This operation will be followed up by "Cyber Showdown III" and "The Yappening II" operations. Playlist refreshes will also launch during CU29, including new map additions to the Big Team Battle, Firefight King of the Hill, and Squad Battle playlists.

CU29 will be the first of many future planned updates that will replace the current "season" model, electing instead to provide smaller content drops but at more frequent intervals.
