An Overview of Customization in Halo Infinite CU29

Information Update 29 (“IU29”) for Halo Infinite is set to launch on January 30 and will introduce the iconic Mjolnir Mark IV armor from Halo Wars, in addition to three fresh Operations, versatile shoulders, new (and returning) HCS packages, and the helmets of Silver Team.


The definition of what it meant to be a Spartan would be established shortly after initial contact with the Covenant, an intergalactic coalition that initiated a war against humanity, which would continue for almost three decades.

On November 27, 2525, Doctor Catherine Halsey and her Spartans were transported to the Damascus Materials Testing Facility on Chi Ceti IV. This confidential military base was where a crucial aspect of the SPARTAN-II program, known as Project: MJOLNIR, had been developed.

A half-ton of ultra-dense composite armor powered by a compact fusion power source, capable of being worn exclusively by humans who had undergone extensive biological enhancement. Equipped with a warship-grade computer core, automedic system, and connections to the UNSC battle network, the Mjolnir Mark IV would become like a second skin to the Spartans, enhancing their speed, strength, and tactical abilities.

Mjolnir Powered Assault Armor would go on to become a symbol of optimism for the UNSC, and quite possibly the most formidable human weapon that the Covenant would soon dread. And so it began…

The renowned Mjolnir Mark IV armor will be introduced as a new free Armor Core in IU29 for Halo Infinite, providing a fresh set of customization options for those who prefer an old-school look on the battlefield. Upon logging into the game after IU29 is released, the armor will be immediately accessible in the Armor Hall.

This will be part of the first of three Operations. Let’s delve deeper into them!


“If they want war, we’ll give ‘em war!”

Dress up your Spartan with customization rewards inspired by the heroes of Halo Wars. The Spirit of Fire Operation Pass features 20 tiers of free rewards available from January 30 to March 5.

For the premium aspect of the Operation Pass, players have two additional choices that can be bought from the in-game Shop or Switcher:

  • 500 credits will make the Operation Pass permanent (it will never expire), offer bonus XP during the Operation’s duration, an extra Challenge slot while the Premium Operation Pass is equipped, and includes an exclusive customization item.
  • 2,000 credits will unlock all 20 tiers of the Operation Pass immediately and includes the exclusive bonus customization item.

The bonus customization item for this Operation is the Evolved MA5—a weapon modification for your Assault Rifle that will transform the sleek and modern MA40 into the classic chunky design reminiscent of the MA5B from Halo: CE and Halo Wars.

Upon the release of CU29, you will also find Red Team’s super-soldier siblings waiting for you in the Shop.

Additionally, for enthusiasts of the Stanchion—an anti-matériel rifle featured in the Halo Graphic Novel, Halo: Contact Harvest, Halo Wars 2, and other media—you can obtain the Stanchion bundle which includes the type of weapon model you might never want to detach from your S7 Sniper Rifle!

Our versatile journey for Halo Infinite’s customization continues with the addition of shoulder pads that can be equipped across any Armor Core.

Similar to before, this multi-use expansion of armor operates retroactively, meaning all of your current shoulder pads are multi-core enabled and all shoulders moving forward will also be multi-core!

Building on the work from previous updates to make helmets, visors, and many coatings multi-use, there are now billions of potential combinations available in Halo Infinite.


The second season of the Halo television series premieres on Paramount+ with a two-episode premiere on February 8, and we have unbeatable Ultimate Rewards for you to earn.

Complete all your challenges on these respective weeks to earn each of these Silver Team helmets, available across all your Armor Cores. Let’s see how those helmets look with some multi-use armor customization.

Visors for each member of Silver Team will also be given as free rewards! Simply log into Halo Infinite on these corresponding weeks and they will be unlocked for you.



After much request from the community, we are reintroducing the bundles for each HCS team that Halo Infinite debuted with back in 2021—with significant improvements!

The armor and weapon kits have been unlocked, meaning you can now customize with these coatings for the first time ever. Additionally, they are all now multi-use which means you can wear the amor, visors, or weapon coatings on any armor, helmet, or UNSC weapon.

This bundle will be available in the HCS Shop when CU29 launches on January 30. If you already purchased this bundle when Halo Infinite released, the content will be applied retroactively—including those for teams no longer in the HCS.

These bundles have only been released for teams that are still in the HCS: FaZe Clan, OpTic Gaming, Sentinels, Spacestation Gaming, and Cloud9.


Year 3 HCS bundles are also arriving alongside CU29 with all-new designs, featuring new multi-use armor coatings as well as visors. These have been created by the teams themselves, featuring their unique branding.

The first of three new weapon models is also included, starting with the Dracon Bandit (for both the M392 Bandit and Bandit EVO). The remaining Grim Reaper and Extermination weapon models will be available later in the HCS season.

Acquire the Dracon Bandit by grabbing the bundle that supports your favorite HCS team—the majority of the profits go to the partnered teams to maintain their involvement in the Halo ecosystem.

That sums up this preview of what’s in store on the customization front for CU29. We can’t wait to see how everybody equips their Mark IV armor.
