Challenges/Halo Infinite

Challenges in Halo Infinite are daily and weekly objectives that players can complete for experience points (XP), which contributes to progression on the seasonal Halo Infinite Battle Passes. Challenges can be earned in multiplayer.

Overview
Challenges are available in three tiers of difficulties ("Normal", "Heroic", and "Legendary"), with corresponding levels of XP rewards. Daily challenges are refreshed everyday at 10:00 am PST. Each day, there are four daily challenges that reward XP for completing multiplayer matches. The XP reward decreases incrementally, starting from 300 XP being rewarded at the first challenge. The second and third challenges reward 200 XP. The fourth, fifth, and sixth challenges reward 100 XP. The seventh challenge, which can be completed multiple times, rewards 50 XP.

Every week, each player is assigned a set of random 20 weekly challenges (8 Normal challenges, 8 Heroic challenges, and 4 Legendary challenges), selected from a pool of 700 potential challenges. By default, all players have three slots for active challenges to complete at any given time. A fourth challenge slot is available to players that have purchased the Premium Battle Pass. Upon the completion of an active challenge, another weekly challenge will take its place, until all 20 challenges have been completed. Upcoming weekly challenges can be accessed from the menu, and players can use the Challenge Swaps consumable to exchange an active weekly challenge for a new challenge from the same tier and same category of gameplay action. Furthermore, XP rewards can be doubled using the Double XP Booster consumable.

When a player has completed all Weekly Challenges in a week, a Weekly Ultimate Challenge (at the "Mythic" difficulty tier) becomes available for completion, which is the same for every player each week. Players that complete the weekly Ultimate Challenge will receive a unique reward, such as an armor piece, a weapon coating, an armor coating, an emblem, or a nameplate.

Weekly challenges are reset every week on Tuesday at 10:00 am PST. During events like the Fractures: Tenrai event, weekly challenges are replaced by event challenges, the completion of which rewards an item on the Event Pass. Event challenges are typically differentiated from weekly challenges with orange banners on their icons. During other events, like the Winter Contingency event, items on Event Pass are rewarded simply by completing the first daily challenge of the day, "Spoils of Sparta".
