Operation: Haloween II Now Undead

Fog gathers. Fear stalks the land. Operation: Haloween II has risen from its dark slumber.
To mark the frightful occasion, we’re trick-or-treating Halo Infinite players to a reanimated Survive the Undead playlist, scary-good Squad Battle updates, haunted helmets, and a creature-feature of Haloween costumes and accessories in The Exchange.

SURVIVE THE UNDEAD

The gruesome gauntlet of Survive the Undead returns for a sequel—with a vengeance.
Appearing in a dedicated playlist now through November 18, the legendary arcade mode now includes four terrifying maps forged by the incomparable Forge Falcons.
STRIVE TO SURVIVE
Missed the first evil incarnation of Survive the Undead? Here’s what awaits you:
Survive the Undead is a Firefight variant with arcade-style play and a built-in points economy. Your goal is to endure endless waves of increasingly more ghastly foes, starting with lumbering Elites and progressing through swifter, deadlier undead assailants.
As you strive to survive against the horde, you’ll earn points to upgrade personal attributes, purchase weapons and ammo, unlock new areas, or roll for powerful weapon modifiers. (Are you a “Sidekick that shoots Shock Rifle bursts” or a “Bulldog filled with rockets” kind of survivor? It’s a personal choice, but one with potentially grave significance.)
Get moving. The nightmare’s just begun.
QUOTH THE FALCONS

HALO 5: GUARDIANS TURNS 10
Here’s a scary thought for all us mortals: October 27 marks the tenth anniversary of Halo 5: Guardians! In a few short weeks, we’ll celebrate the milestone with the return of Extermination and four beloved armor sets from Halo 5: Guardians multiplayer.
COMING SOON: EXTERMINATION

Extermination is a 4v4 Slayer variant where your team must wipe out the entire enemy team before their fallen comrades return to action. Once you drop a foe, you’ll have 15 seconds to eliminate their allies—or else the clock resets to the time remaining since the next enemy fell in action.
Stay tuned for a dedicated Extermination playlist on October 28.
COMING SOON: ANNIVERSARY ARMOR

On October 28, four armor sets commemorating Halo 5: Guardians will take on new missions in Halo Infinite. Inspired by favorite multiplayer helmets, these anniversary armor sets will arrive simultaneously in both The Shop and The Exchange.
- Hunter: Savvy Spartans choose HUNTER technology for its customizable interfaces, a puissant surveillance suite, and dependable maneuverability in hand-to-hand sparring.
- Helljumper: Thanks to innovative field upgrades by Cascade Stronghold Technologies, testbed HELLJUMPER armor can reliably endure the atmospheric rigors expected of GEN3 Mjolnir.
- Copperhead: When it comes to building interspecies alliances, COPPERHEAD armor has consistently proven its merits for both kinetic diplomacy and charm offensives.
- Shinobi: Though the design’s origins remain obscure, the undisclosed reasons behind its approved use among Spartans of the UNSC may prove even more unknowable.
Better start squirreling away those Spartan Points for later in the Fall Update!
SQUAD BATTLE REANIMATED

As the chilly autumn air announces the onset of winter, this Haloween season is the perfect time to cozy up to a Squad Battle Refresh! Jump into the Squad Battle playlist to sip on:
- New maps: Take a stroll through familiar stomping grounds in Longshore (returning from Halo 3) and First Light (a remake of Halo 4’s Daybreak).
- Loadout changes: Watch enemies fall like autumn leaves with a new default loadout. Squad Battlers now start with the M392 Bandit and the MA5K Avenger.
- Improved matchmaking: We’ve added new functionality to Squad Battle’s matchmaking systems to improve queue times in cases where your Match Composer recipe may be too restrictive. To get you into the fight faster, the matchmaker will start with your selected modes as a preference, then slowly widen its scope to find you a match in other available modes.
- KOTH updates: We’ve modified scoring in Squad Battle’s King of the Hill variants for a more traditional flavor. Teams now earn one point per second while holding a hill, but hills rotate around the map every 60 seconds. Strategize, choose your hills wisely, and accrue 180 points to win!
With throwback maps, perfectly spiced KOTH, and a fresh batch of weapons, there’s never been a comfier way to enjoy a nostalgia-inducing 8v8.
OPERATION PASS

As specters, spooks, and Spartans mingle in the gloom, what abominable armaments lie in wait at the end of Operation Pass Lane? Ring the bell if you dare...
FREE OPERATION PASS

Brave the fateful machinations of Operation: Haloween II to unearth the Dirgesinger armor set, featuring none other than the Gravemind’s terrible visage. Wrought patiently from flesh and bone and time, this haunted helm afflicts all those who look upon it with a certain infectious charm.
Complete all 20 tiers of the free Operation Pass by November 18 to join your voice with the Dirgesinger’s timeless chorus.
PREMIUM OPERATION PASS

Those who delve into the mysteries of the Premium Pass shall maximize their pestilential potential with the Defiled Needler weapon model and Corrupting Oil weapon coating.
Premium Pass reward tracks cannot be killed with mortal weapons (they never expire!). Premium Pass holders can also earn bonus XP and deploy an additional challenge slot while their pass is equipped.
QUALITY-OF-AFTERLIFE UPDATE
When the Halo 5: Guardians anniversary celebration begins, we’ll be releasing a pair of quality-of-life updates to help matchmakers and Forgers conduct their dire deeds!
Improved Mode Titles
Starting October 28, matchmaking modes will follow a more consistent title format for easier searching, bookmarking, and discovery.
Whereas the titles for some modes used to contain info about their player count or default playlist (e.g., “Arena: Slayer”) in varying order, all Halo Studios mode titles will soon be normalized to adhere to a simplified “[MODE]: [SIZE][VARIANT]” format.
For example, a core mode such as “Slayer” will now be listed under that name, while Slayer’s 24-player Fiesta variant can be found under “Slayer: BTB Fiesta.” We hope this will improve the way players find new multiplayer experiences in Halo Infinite.
Updated Forge Canvases
We’ve amended the set of Forge Objects that are available by default on Canvases to include support for all core mode variants.
Starting October 28, you will now find a variety of utility Objects for Invasion, Assault, and more mode variants on all eight Forge Canvases (Arid, Barrage, Ecliptic, Institute, Mires, Permafrost, Seafloor, and Void) to make iteration and design easier and more fluid than ever.
THE FALL UPDATE LIVES!

As shadows recede, and warpaths turn astray, Operation: Haloween II descends to strike fear into the hearts of Spartans everywhere.
Recite the ancient words found in our Fall Update overview to summon the Vestige Carbine, the fearsome Falcon, fiendish new Weapons Bench customizations, and more game-changing autumnal updates.
WAYPOINT CHRONICLE
Coming this month are two new Waypoint Chronicles to celebrate the arrival of Haloween and the tenth anniversary of Halo 5: Guardians.
ASCENSION ON ATROPOS / OCTOBER 8
“October 2556. The crew of the UNSC Saturn deal with the consequences of a catastrophic Flood outbreak at LV-31, and a fanatical alien cult seeks to find a new path to divine transcendence.”
FIFTH CANTICLE / OCTOBER 27
“2558. Amid the chaos of the Created uprising, five tales of truth, compromise, betrayal, purpose, and change unfold across the galaxy.
Doctor Catherine Halsey and Jul ‘Mdama share an honest conversation, Captain Lasky makes arrangements for a vital mission to Sanghelios, Arbiter Thel ‘Vadam confronts a traitor, Exuberant Witness makes some new friends, and a strange signal is picked up on Zeta Halo.”
THE SHOP

This spooky season, the resident necromancers at The Shop have raised a devious duo of armor bundles for the frightfully inclined.
ALL HALO'S EVE BUNDLE
‘Twas all Halo’s Eve when a harvester of unbound souls met a hunter of the damned. The All Halo’s Eve bundle joins the Helsinger and Gourdian Knight armor sets at a dire crossroads with an exclusive death effect and an extra-sweet assortment of Haloween treats.

- Helsinger: The HELSINGER title is bestowed on those forged by arcane trials against light-fearing abominations. Let its singular purpose drive your hand to divine victory over the emissaries of ancient evils. Be sure to anoint the Hive Stalker Shock Rifle with the Eye Candy weapon coating before heading out on tonight’s hunt.

- Gourdian Knight: O, Gourdian Jack is a merry fellow! His teeth are jagged and his eyes are yellow! Brave the moonlit moors of the fallow court to ride full abreast with this gleeful harvester of sorrows. As you sneak up on unsuspecting mortals, you can snare admiring looks from fellow bumps-in-the-night with the Weaver’s Embrace armor coating, or snuff your luminous approach with the Candlejack helmet attachment.

- Revealed Truth: Why should death seal their lips? Ply your enemies for a "flood" of closely held secrets with the bundle-exclusive Revealed Truth death effect.
Pick up the All Halo’s Eve bundle to acquire the Helsinger and Gourdian Knight armor sets, Hive Stalker Shock Rifle weapon model, Eye Candy weapon coating, Weaver’s Embrace armor coating, and the Revealed Truth death effect set.
PROMETHEAN RAIDER
Beneath the full moon howls the Promethean Raider bundle, an unholy union of favorite customizations conjured especially for Haloween. This ferocious pack includes the Raider armor set (introduced in Operation: Last Stand), Promethean Bulldog weapon model, Worn Sky armor coating, Academy Issue and Second Foundation weapon coatings, Chibi Johnson weapon charm, and Behold Sector backdrop.
