While purchasing and progressing through the Halo Infinite Battle Pass is the primary way players can earn cosmetics in Halo Infinite's multiplayer, it's not the only way. Each week, players have an opportunity to complete an Ultimate Challenge, at which point they'll be rewarded with a special reward.
In this guide, we'll go over what the Ultimate Challenge and reward is this week, how to get Ultimate Challenges, when they refresh each week, and all of the past rewards that have been offered for completing Ultimate Challenges (they may return in the future).
How to get Halo Infinite Ultimate Challenges
To get the Ultimate Challenge that's available each week, players will need to complete all of their other weekly challenges for the week. Currently, players are given 20 different weekly challenges every week, though this number could change in the future. Once all 20 of these weekly challenges are completed, players will then be given their Ultimate Challenge for the week.
Halo Infinite Ultimate Challenge and reward this week
The Halo Infinite Ultimate Challenge this week is Buddy System, which requires you to get five Double Kills in PvP matches. This is best achieved with power weapons or vehicles, so we recommend playing Fiesta or Big Team Battle to complete this challenge.
After completing the challenge, players will unlock the Sacrifice armor emblem (see above). The emblem is blue, yellow, and black, and it depicts Halo: Reach's Noble Six holding Spartan Kat's dogtags. Players can equip the emblem on their armor in the Customization menu.
Past Halo Infinite Ultimate Challenge rewards
While 343 Industries may never bring back some past Ultimate Challenge rewards, we're archiving them here as they may return at some point. If they do, players may want to plan which returning rewards they want to grind for ahead of time.
