Halo Infinite’s latest update, Content Update 29 (“CU29”), has arrived alongside the launch of the newest Operation: Spirit of Fire!

The latest free update for Halo Infinite brings the legendary Mjolnir Mark IV armor core, multi-core shoulder customization alongside a slew of HCS and Silver Team-themed goodness for your Spartan, a new map, three new Operations, and much more—let’s dive into to check it all out…



  • UPDATE OVERVIEW – Catch up on our January 19 Community Livestream which outlines the content in this update and our approach to Halo Infinite going forwards this year.
  • MAP OVERVIEW – Take a guided tour of Illusion, the new Arena map.
  • FORGE OVERVIEW – Learn more about the new features and improvements coming to Forge, including the Covenant palette, Mode Creator, and more.
  • CUSTOMIZATION OVERVIEW – Get a closer look at the Mark IV Armor Core, customization improvements, and upcoming Operations.


As part of today’s update, all players will receive the classic Mark IV Armor Core for free. Simply jump into the game and you’ll find it waiting for you in the Armor Hall.

This fan-favorite armor has appeared in the likes of Halo Wars and Halo Wars 2, Halo Legends, Halo 5: Guardians, and now this legendary iteration of Mjolnir has come to Halo Infinite.

And what better way to kick off the update than with the opportunity to further outfit the Mark IV Armor Core?

Enter Operation: Spirit of Fire, which runs from January 30 to March 5 and features 20 tiers of free customization rewards, including new armor attachments, coatings, weapon charms, emblems, and more.

You know the drill with Operations now: in addition to the free pass, there are two additional premium options you can purchase.

  • 500 credits will make the Operation Pass durable (it will not expire), offers bonus XP during the Operation’s live window, an extra Challenge slot while your pass is equipped, and comes with an exclusive customization item.
  • 2,000 credits instantly unlocks all 20 tiers of the Operation Pass at purchase and includes the exclusive bonus customization item.

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

When the Spirit of Fire Operation concludes on March 5, there are still two more free Operations that will take us through April 30!


Themed around the concept of a “viral machine,” the latest exploration of these Created champions veers more into the realm of cybernetic horror that reflects the twisted nature of their creation. Jump into Halo Infinite on March 5 to unlock 20 tiers of new customization rewards for your CHIMERA Armor Core. 


The Yappening II arrives in April to help you celebrate the season of fools with 20 tiers of Grunty goodness. 


Today’s update also brings a brand-new map to Halo Infinite, titled Illusion.

Illusion takes place within an abandoned ONI black site where old experiments with recovered (and familiar) Covenant technology remain.

Described as a love letter to the map design of Halo: Combat Evolved, Illusion features a unique mid-section where a corridor possesses the traits of active camouflage—so players who go into the center will turn invisible.


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

Like before, this multi-use expansion of armor works retroactively, so all of your current shoulder pads are multi-core enabled and all shoulders going forward will be multi-core as well.

Following on from work that has been accomplished over previous updates to make helmets, visors, and many coatings multi-core, there are now billions of possible combinations available in Halo Infinite. We can’t wait to see the latest and greatest Spartan drip out on the battlefield!

Forge continues to evolve as we target highly requested additions, enhancements, and quality-of-life improvements. Here are some of the highlights of the new toys you’re able to play with in Halo Infinite’s Forge:

Need more purple? Over 70 new Covenant-themed structure pieces, primitives, accents, and decals are now available for Forgers to create exciting experiences that harken back to Halo’s roots.

This new functionality allows players to script modes in the Node Graph like a prefab, then save, share, and play those experiences—just like you would share a mode created in the Custom Game menu.

The Forge Mode Creator will make it easier for modes to be shared and played, hooked up to community maps, and free up map budget (as mode logic will no longer come with a map budget cost).

To learn more about the ins and outs of the Forge Mode Creator (along with a more thorough breakdown of other additions and improvements), check out our Forge Overview blog!


Players can now adjust up to three colors on select foliage objects and add further set dressing and detail to their maps with decals that mimic stains, foliage overgrowth, and more.

New behaviors and traits have been added to the Forge AI Toolkit, including:

  • New Squad Behavior – Wander When Idle

Available on the AI Spawner object. When set to ON, AI units in this spawned squad will wander around their assigned AI Move Zone when idle.

  • New AI Trait Nodes

New AI Traits include:

  • Bonus Health
  • Bottomless Clip
  • Damage Resistance
  • Health Recharge
  • Movement Speed
  • Movement Speed With Turret
  • Prevent Weapon Firing
  • Vampirism
  • Weapon Damage

More is on the way to Halo Infinite’s Forge this year, including Flood and alien-themed palettes.


Season Two of the Halo television series debuts on Paramount+ with a two-episode premiere on February 8, and we’ve got some unmissable 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. 




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 demand from the community, we are bringing back the first bundles for each HCS team that Halo Infinite launched with back in 2021—with some major improvements!

The armor and weapon kits have been unlocked, which means 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 armor, visors, or weapon coatings on any armor, helmet, or UNSC weapon.

If you already purchased these launch bundles when Halo Infinite released, the content will be applied retroactively. If you missed these bundles the first time around, they’re now available again for teams that are still in the Halo Championship Series: FaZe Clan, OpTic Gaming, Sentinels, Spacestation Gaming, and Cloud9.


Year 3 HCS bundles have also arrived 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.

Additionally, acquire the Dracon Bandit weapon model for the M392 Bandit and Bandit EVO 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.


Head to the Shop and you will find some exciting new Halo Wars-inspired bundles, featuring the likes of Omega Team to further outfit your free Mark IV armor...
