Silent Auditorium

Complete the Silent Auditorium mission in Halo Infinite with our comprehensive guide. Learn how to defeat Brutes, Hunters, and the Harbinger, and find the Bandana Skull.

The mission begins with you being thrown into yet another fight filled with Banished Brutes, Jackals, and Grunts. There’s also two plasma cannons in the distance, so you’ll need to take these out by shooting through the shield barrier, then head shot the operator of the cannon. Ideally, you should destroy the cannons so that no other enemies begin to use them. The most dangerous enemies in this room are Elite Brutes, especially those wielding Energy Swords. You’ve encountered these before, and they’ll use Active Camo at some point during the fight. Remember to use Threat Sensor to expose their position so you’re not attacked in melee from the shadows. At the beginning of the fight you’ll find yourself close to some lower floor areas where you can crouch to take cover, but this won’t protect you from the most damaging AoE attacks. You may find it easier to push towards the left side of the room, where there are more weapon racks, grenade refills, and where you can still hide from the cannon behind pillars and get a decent visual on it to destroy it quickly.

Once you’ve dealt with the enemies in the first room, you’ll find yourself in a hallway with a crucible which powers the door nearby. You’ll need to take the power seed opposite the crucible and place it to open the door. Beyond this you’ll encounter some remnants of data from Cortana, after which you’ll enter a room with two powerful Hunters. These are tougher than regular hunters, and their weapons inflict more damage. However, the same principle applies when taking them down: use the most damaging power weapons available to you, and try to focus on one Hunter at a time to reduce the chances of being caught off guard by one later in the fight.

In a situation where you don’t have access to Escharum’s melee weapon, you’ll still find enough power weapons in the room to deal with the two Hunters. The Sentinel Beam can be found on the floor nearby, alongside ammo crates and a bunch of grenades. You’ll want to use these grenades as you kite the Hunters around the room to inflict extra damage. You’ll also find a Ravager on the nearby weapon rack, which will inflict massive damage to both Hunters. One of the most effective ways to target them consistently is by moving around a weapon rack or pillar. This should keep the Hunters interested in firing at you from a distance, rather than charge at you to locate your position. If you want to throw some extra damage into the mix, be sure to make use of the nearby blast coils. You can use Grappleshot to bring them into your hands from a distance, or just shoot them when the Hunters are near enough to one. The grapple is also useful for quickly escaping Hunters when they charge you, allowing you to grapple onto nearby pillars to swing across to the other side of the room.

After dealing with the two Hunters, interact with the terminal to unlock the door and go through the hallway. You’ll come across a split in the path, with one route taking you right and the other left. The route on the right leads you to a weapons room, where you can restock on power weapons and grenades including a Shock Rifle, Sentinel Beam, Cindershot, and Heatwave. The route on the left progresses with the mission, leading to more data from Cortana and more rooms with Banished enemies. If you want to be absolutely sure that you don’t kill any Sentinels in the rooms ahead, you can just run through them and beyond all the enemies present. However, you’ll need to use power equipment such as the Grappleshot and Thruster to avoid taking too much damage. If you do decide to fight the Banished in these rooms, try not to use weapons which inflict massive AoE (Area of Effect) damage such as the Heatwave or Cindershot, and limit your grenade use unless you’re absolutely certain that there are no Sentinels in the area. A single missfire or throw can result in the death of a Sentinel, given that they’re so weak.

Once you’ve fought through numerous rooms with Banished and the odd Sentinel (or ran through them to avoid killing Sentinels!), you’ll eventually encounter the Adjutant Resolution for a third time in the story, but this time it will be friendly and apologetic. Follow it through the rooms towards the Silent Auditorium, and when you reach a large room with a blue bridge and an elevator at the end of it, stop here and go through the door over the smaller blue bridge opposite the door from where you just entered. If you didn’t kill any Sentinels, this door will be active (glowing in blue light) and you’ll be able to enter the room to find the Bandana Skull inside. If you killed any Sentinels along the way through this mission, the door leading to the room with the Bandana skull will be locked.

Now that you have the skull, use the elevator to reach the Silent Auditorium. A long cutscene will play here, after which you’ll find yourself facing the Harbinger in combat. The first phase of the fight will consist of numerous waves of Brutes, Jackals, Grunts, and Skimmers. You’ll need to fight these off before the Harbinger will enter the fight. Try not to use or destroy too many of the power coils at this early stage in the fight. They’ll be much more useful later on when you’re facing tougher enemies. When you’ve defeated the first wave of enemies, the Harbinger will attack.
