The Halo games have always had bosses, but Halo Infinite takes it a step further and adds named enemies to take out while exploring, and when playing main campaign missions. These tough encounters must be won in order to progress with the story.

Near the end of the Foundation mission in Halo Infinite, the named enemy Tremonius will appear with two Jackals. However, just because he's the first Boss, that doesn't mean he's easy to take down—especially if playing on Heroic or Legendary difficulty. This Tremonius Boss guide will help players defeat the Brute on any difficulty.

Tips and Tricks to Defeat Tremonius Boss in Halo Infinite

The six main tips and tricks to remember when trying to defeat Tremonius in Halo Infinite are:

  • Use Plasma Weapons to kill the Jackals first.
  • Use Plasma weapons and Plasma Grenades to quickly lower his shields (the white bar).
  • Then use the Needler (or Kinetic weapons) and any type of Grenade to quickly lower his health (the red bar).
  • Deploy the Grappleshot to quickly find cover if low on shields.
  • Use ammo refill stations when running low.
  • Pick up different guns if the current loadout isn't effective.

How to Defeat Tremonius Boss in Halo Infinite

The first thing players should do is take out the Jackals when battling Tremonius. This is especially important if playing on Legendary, as they can take Master Chief out in only a few shots. Quickly find cover and then use a Plasma weapon to kill them, like the Pulse Carbine, or even Halo's Plasma Pistol. Remember to charge the pistol's shots before firing.

Once the Jackals have been defeated, use the same Plasma weapons to quickly take down Tremonius' shields. This is the white bar above him. If players don't lower his shields fully in enough time, they will recharge again. If running low on ammo, be sure to use the ammo resupply caches nearby. Use the Grappleshot if needing to make a quick retreat behind cover to recover Master Chief's shields.

Once his shields are gone, use a Needler to kill Tremonius quickly. Don't stop while shooting, as it's best to empty a whole clip. If players don't want to use the Needler, they can use a Kinetic weapon instead. Any type of grenade will take large parts of his health off as well. If Tremonius is still proving too difficult to defeat, players can change the difficulty in Halo Infinite if they want to.

If wanting to take on Tremonius again, a new save file will need to be created, as the Halo Infinite campaign won't let players replay story missions at launch.

Halo Infinite is out now on PC, Xbox One, and Xbox Series X|S.
