Season

Seasons are a feature of Halo: Reach, Halo 5: Guardians and Halo Wars 2, 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 customisation unlocks and gameplay improvements.

Halo: The Master Chief Collection seasons
Seasons were first introduced to Halo: The Master Chief Collection with the addition of Halo: Reach to the collection in December 2019. As of December 2020, 343 Industries intends to support the game with seasonal content roughly every two months, with current plans giving the game a ten total seasons. Following the release of Season 10 will determine whether more seasons will be released.

Season points
Season points are a new in-game currency introduced with the Season system. They can be used within the various unlock tiers of each season to unlock armor permutations, skins, nameplates, Firefight voices, and more. Initially, season points could only be earned by progressing in the game's rank scheme through regular multiplayer, though the addition of Challenges has resulted in a wider array of season point earning potential across multiplayer, campaign, Firefight, Forge and custom games. Season points are a purely in-game currency, and cannot be bought through real-world purchases.
