The Halo series and its campaigns have always featured a variety of collectibles to find. This is no different in Halo Infinite, and it features skulls, audio logs, and more. There are many areas on the map during its open-world segments where players can find these. One location is Outpost Tremonius.
Opening your Tac Map in Halo Infinite will show you all the collectibles at each level. For Outpost Tremonius, there is three Spartan Cores, a Mjolnir Armor Locker, and a Banished Audio Log. Here is where to find all these collectibles in Outpost Tremonius.

Spartan Cores
There are three Spartan Cores to collect in Outpost Tremonius. The first is encountered almost immediately in the level and cannot be missed. After defeating Tremonius, players will begin to make their way to Zeta Halo. Immediately in front of the player is a box with a green light flashing. This is the first Spartan Core.
Players can find the second after opening the bay doors that lead to Zeta Halo. Take a right out of the building and follow the path between the cliff and the building. The player will come upon some wreckage where the core will be.
The final Spartan Core is found further into the base. Follow the path that leads underneath the landing pad. Around the corner and to the left will be the Spartan Core resting beside some weapons.
Banished Audio Log
Turn around from the final Spartan Core and begin making your way up the path. To the left are some crates. The Banished Audio Log will be here resting against the crates on the wall.
Mjolnir Armor Locker
The Mjolnir Armor Locker can be found next to the landing zone. It is at the beginning of the platform beneath the post and beside some crates.
