Halo Infinite: Operation Haloween

It’s that time of year again where there’s a chill in the air, the wind howls and bites as the night comes early, a thin mist settles over the fields, and humanity marches on—their minds and bodies fueled by pumpkin spice lattes... With this change of the seasons, it is also time for a new Halo Infinite Operation. Welcome to Haloween!

Get yourselves in the Haloween mindset with the Survive the Undead playlist. Grab your friends, gear up, and jump into a unique twist on Halo Infinite’s Firefight experience as you stand your ground against endless waves of enemies that have been banished from their graves.

Celebrate Haloween with a free new Operation Pass, consisting of 20 tiers and featuring the Spartanstein armor set. This free cosmetic Halloween-themed "operation pass" launched aside this update and ran from October 8, 2024 to November 5, 2024. It was made available in perpetuity to those who purchased the pass.
