Outpost Tremonius is the third mission in Halo Infinite, and there are five collectibles to be found within it. Those collectibles are three Spartan Cores, one Banished Audio Log, and one Mjolnir Armor Locker, and some of them can prove to be a bit elusive. For those players that want to make sure that they obtain all of the Outpost Tremonius collectibles in Halo Infinite, details on their locations can be found in this guide.

To note, it is currently not possible to replay missions in Halo Infinite, though it is indicated that a replay feature will be added in the future. Players that are reading this close to the game’s launch are thus advised to be very meticulous in their hunts for collectibles, as they will not be able to go back for any that they have missed. While missing some collectibles will certainly not prevent a player from finishing the campaign, it is not ideal for those fans that are going for 100% completion.

Halo Infinite Outpost Tremonius Collectible Locations

Spartan Core #1

Players will find the first Spartan Core in Outpost Tremonius as they start this Halo Infinite mission. Specifically, it is in the green UNSC container that is near the entrance.

Spartan Core #2

Fans will encounter another Halo Infinite Spartan Core not long after opening the bay door and reaching Zeta Halo’s surface. Indeed, players should turn 90 degrees to their right as soon as they pass through the doorway, walk forward a few paces, and then turn 90 degrees to the right again. Fans should now be positioned next to the bunker’s exterior wall, and they should walk forward until they run into the UNSC container that holds the core.

Banished Audio Log

Back at the bay door, players should make their way down the metal ramp and continue to follow the dirt pathway downward. Fans should move forward, walking over a rectangular metal object, and then turn slightly to the left to go down a bit further. Players should now walk toward the cliff that is in front of them to find the Banished Audio Log propped against a large metal object.

Spartan Core #3

From the position of the Banished Audio Log, players should turn 180 degrees and walk forward. Fans will soon find themselves passing some buildings that are on their left, and the UNSC container with the third Spartan Core is just past a metal ramp that leads into one of those structures.

Mjolnir Armor Locker

Players should now continue toward the landing zone, making their way up a dirt pathway. This path will eventually lead to a metal platform, and fans can find the Mjolnir Armor Locker just to the right before they walk onto that platform. After looting it, players will have obtained all of the collectibles in Outpost Tremonius, and they can continue to progress through Halo Infinite's campaign.

Halo Infinite is available for PC, Xbox One, and Xbox Series X/S.
