Halo Infinite: All Outpost Tremonious Collectibles & Locations

Wondering where to find all of the hidden collectibles in Outpost Tremonious in Halo Infinite? Here are all of their locations.

There are five Outpost Tremonious collectibles in Halo Infinite. Unlike some of the other hidden items in the game up to this point, most of these locations are relatively close together. But there's no reason for you to look for them yourself. That's what this guide is for.

Some of these collectibles in Outpost Tremonious will be the first you come across for two achievements:

  • Hidden Experience: "Located and secured a Spartan Core."
  • Money in the Bank: "Accessed your first Mjolnir Armor Locker."

In Outpost Tremonious, you'll find five total collectibles: 3x Spartan Cores, 1x Banished Audio Log, and 1x Mjolnir Armor Locker.

Remember that you can always use Scan to look for collectibles in the immediate surrounding area. Press "Z" on PC (mouse and keyboard) and down on the directional pad on controller. Collectibles like Audio Logs will light up with orange outlines, and Skulls will show up as blue dots. Though, not all are visible depending on their locations. 

All Halo Infinite Outpost Tremonious Collectibles Locations

Spartan Core 1

This Spartan Core collectible in Outpost Tremonious is impossible to miss. As soon as you enter the area from Foundation after fighting the boss, this green and silver pulsating crate with the UNSC symbol above it will be in front of you. You'll get the Hidden Experience achievement for picking up this Spartan Core. 

Spartan Core 2

After encountering Escharum's hologram shortly after the first Spartan Core, the bunker will open, exposing the open world of Zeta Halo. Walk to the edge of the metal platform, and turn right. Go toward the cliff face, and turn right again. Go behind the Outpost Tremonious bunker to the end of the path. The Spartan Core collectible chest will be against some wreckage.

Spartan Core 3

From the second Spartan Core, turn around 180 degrees, and go toward the primary objective for Outpost Tremonious (use scan to find its direction). Go down into the encampment beyond the bunker, but stay on the left side, going past the orange shields. 

Mind the enemies, and go past the wall in front of you (the one with the broken metal slats/bars). Just past that, turn left. The Spartan Core collectible crate will be in front of you by a large red and grey armory crate full of guns.

Banished Audio Log: Outpost Intel — In Your Honor

From the third Spartan Core, turn around, and go straight ahead. The terrain will go down in front of you, heading toward some large red and grey crates and a gun rack. The Banished Audio Log collectible will be hidden amongst the crates, leaning against the large crates up against the cliff, on the left side.

Mjolnir Armor Locker

Now go up to the Outpost Tremonious landing pad, the primary objective. Just before you reach the landing area, look to the right of it. You will see a tall Mjolnir Armor Locker collectible leaning against a light post. You can't miss the green UNSC logo above the Locker.

You'll get the Money in the Bank achievement when you interact with it.
