Season

Seasons are a feature of Halo: Reach, Halo 5: Guardians, Halo Wars 2, Halo: The Master Chief Collection, and Halo Infinite, primarily focused on their games' respective competitive modes. Seasons have typically accompanied new ranked settings, a handful of title updates and patches and accompanied the release of DLC. Leaderboards on Halo Waypoint are additionally organised by season, with a new season seeing the reset of leaderboards and new matchmaking playlists.

Seasons were introduced to Halo: The Master Chief Collection following the 2019 release of Halo: Reach and the collection for PC, serving as the game's ongoing post-launch support with each new season bringing new cosmetic customization unlocks and gameplay improvements.

Halo Wars 2
Seasons are present in Halo Wars 2. During the first year of the game's life cycle, seasons were released roughly once a month to coincide with downloadable content releases or other events such as the launch of Xbox One X. Since then, the output of Seasons has slowed to as little as one per-year. Seasons are a fixture of the game's ranked multiplayer, used for leaderboard and rank resets. Season refreshes are typically accompanied by a Title Update, and may have several mid-season patches.

Halo: The Master Chief Collection
Seasons were first introduced to Halo: The Master Chief Collection with the addition of Halo: Reach to the collection in December 2019. Players can earn Spartan Points and spend them in any Season of their choice to claim its rewards. Initially, 343 Industries intended to support the game with seasonal content roughly every two months, planning to give the game ten total seasons. Later in Halo: The Master Chief Collection's lifespan, it was announced that Season 8 will be its last update on a seasonal model, however the game will still receive more updates that are smaller in scope, with additional features, fixes and content, which are going to be released in 2022 and 2023 as they become ready.

Halo Infinite
Seasonal content for Halo Infinite multiplayer will include armor permutations. Four seasons have been mentioned for the game, though due to its pre-release nature these aspects are subject to change. Like The Master Chief Collection, seasons are expected to last and release every 2–3 months. Unlike The Master Chief Collection, Halo Infinite ' s Seasonal progress will be based on earning XP via the completion of daily and weekly challenges or spending credits; each unlock across the 100-tier Pass will require the same amount of XP.
