On this page of the Halo Infinite guide you can find a list and locations of all collectibles appearing in Mission 11 (Nexus) from the Reformation chapter of the campaign. This page will help you obtain 100% of the secrets in Mission 11, which are 2 UNSC Audio Logs.
There are 2 collectibles to find in Mission 11 (Nexus):
- UNSC Audio Log x2
UNSC Audio Log - The Mission
The first audio log is obtained automatically in the course of the Nexus mission - you cannot miss this one. It should be added to your collection right after reaching the room with the spire holograms and interacting with the central console to receive access to the Nexus.
UNSC Audio Log - Barely Anything Left
The second audio log is obtainable right after the first one - specifically after receiving an objective to activate a gravity lift by finding and delivering 3 power seeds. Go to the door in front of you looking from the location you found yourself in after the cut-scene concluded.
After opening the door, explore the nearest corridors, and very quickly you will come across the secret you are looking for.
