Halo Infinite Adds New Game Mode, Six Months After Its 'Last' Major Content Update

Back in November of 2025, we reported on Halo Infinite's final major content update for Xbox and PC, with the development team noting at the time how they needed to put extra focus on multiple new Halo titles in the works.

So, there was a lot of surprise last night when a sizeable Halo Infinite update randomly appeared, and it's since been revealed that this new update adds a new game mode in the form of Operation Firefight: Gauntlet!

Here's a bit about it, along with a YouTube Short featuring some gameplay footage:

"Seconds into your first match of Firefight: Gauntlet, you’ll understand the name. This deviously difficult PvE mode introduces upgradeable attributes, elimination objectives, and auto-scaled difficulty settings to a boss-filled Firefight experience designed to challenge even the toughest Spartans. Bring your mightiest warriors, because each phase of the Gauntlet is harder than the last."

The official patch notes for this update go into more detail about Firefight: Gauntlet, including how there are five battle arenas, four player attributes (damage, recovery, resistance and speed), a new "AI Aggro" system that "tracks and displays how the enemy’s attention is divided amongst players", and various aspects of the mode that are randomised each time you play.

So, if you fancy checking out some brand-new content in Halo Infinite, you can go and download the update now on Xbox One, Xbox Series X, Xbox Series S and PC — it should be around 10GB or less across all platforms.

We'll leave you with another description of what you can expect from Firefight: Gauntlet:

"In the new Gauntlet game mode, four players must work together to survive a series of challenging, high-intensity battle arena simulations. Each battle arena is defended by endless waves of enemy forces, which can only be stopped by defeating the arena’s champions.

Waves within a battle arena will become more intense over time and, if players take too long to defeat the arena’s champions, the Harbinger will enter the fray too. As players progress through the map’s five battle arenas, the difficulty level of the enemy AI will also increase. Once an arena’s champions are defeated, players will have 30 seconds in the hub area to restock their weapons and equipment before they are sent to the next arena."
