Challenges/Halo: The Master Chief Collection

Challenges are a feature of Halo: The Master Chief Collection added with the launch of Season 2: Spark. Challenges can be earned in all gameplay modes of The Master Chief Collection across all games, and upon completion provide the player rewards of XP for ranking up and Season Points to spend on armor customization items such as armor permutations for Halo: Reach and skins for Halo: Combat Evolved. The addition of challenges allows players who don't wish to engage in competitive matchmaking multiplayer a way to still earn progression via Campaign, Firefight, Custom Games and even Forge.

Challenges are reset every week on Wednesday at 10:00 am PST.

Challenge types

Challenges are divided into three categories; Weekly PvP, Weekly PvE, and Seasonal, with a special fourth category available on occasion for in-game events. The weekly challenges reset every Wednesday, providing a constant new source of activities to do, while the Seasonal challenges reset at the launch of a new Season. As such, Seasonal challenges take longer to complete but offer larger rewards.

Weekly PvP

PvP challenges can be unlocked by playing Social and Competitive multiplayer matchmaking. These challenges typically offer 15,000-25,000XP and 0-1, and can be unlocked for winning matches, performing kills with certain weapons/vehicles, earning Medals and other similar tasks. Each week, 12 challenges (six rewarding 1 and six rewarding 0) are made available from the list below, along with the "Peoples vs Peoples" challenge.
