Mutilator and Mutilator Madness
A brand new weapon called the Mutilator will be added to Halo Infinite. This double-barreled shotgun also has a Gravity Hammer for Melee attacks. Moreover, to celebrate the addition of this weapon, a new playlist called ‘Mutilator Madness’ will be available.
During this game mode, eight players will battle it out to become the Juggernaut and wield this weapon. Players can become the Juggernaut if they slay the current Juggernaut. Moreover, the longer you remain a Juggernaut, the more points you will gain.
Playlist: Battle of the Academy

You must defend your allies and commit acts of sabotage in this new playlist. Four players will defend and escape against the Banished forces. This mode follows the story of the UNSC forces, which defended the Avery J. Johnson Academy for Military Science.
New Operation Pass: Last Stand

This update features a 50-tier Premium Pass reward track and various Shop bundles. The Premium Pass users will have access to all 50 tiers of rewards, along with the free rewards in the first 20 tiers of the Operation Pass.
If you buy the Premium Pass within the five week time period, it will remain available to you even after the period is over.
