It’s that time of year again when the air turns crisp, the wind whistles and nips at your skin as dusk arrives earlier, a light fog drifts across the fields, and humanity pushes forward—powered by pumpkin spice lattes and the spirit of the season. With the arrival of autumn, it’s also time for a brand-new Halo Infinite Operation. Welcome to Haloween! Get into the Haloween spirit with the Survive the Undead playlist. Gather your squad, suit up, and dive into a fresh take on Halo Infinite’s Firefight mode as you face off against unending hordes of enemies who’ve been cursed to rise from their eternal slumber. Celebrate Haloween with a free new Operation Pass, offering 20 tiers and including the Spartanstein armor set. This Halloween-themed "operation pass" launched alongside this update and was available from October 8, 2024, to November 5, 2024. Those who claimed the pass received permanent access to its rewards.
