Halo Infinite

How to Complete Fob Delta

Shane Williams

This page is a walkthrough for the Fob Delta Side Mission in Halo Infinite. It’ll navigate you through the necessary steps to capturing and where to find a UNSC Audio Log.

Head to this location on the map to find the FOB Delta.


Begin the Main Mission: Excavation Site


When controlled, Forward Operating Bases reveal Banished and UNSC activity in the surrounding region, serve as fast travel hubs and rally points of UNSC Marine fire support, and prove access to vehicle drops, weapons, and weapon variants. Gaining Valor unlocks available resources at all captured FOBs. Defeat the Banished and access the terminal to claim this FOB.

Defeat the Enemies and collect UNSC Audio Log

Once you’ve initiated the main mission, Excavation Site head northeast of FOB Golf to find another another outpost owned by the Banishesh, FOB Dolta. Here you’ll need to defeat all the enemies within the area, but this time they are carrying Energy Swords and can go invisible. Thankfully you can stand on the nearby pillars which will prevent the enemies from being able to reach you. Equip your Threat Sensor and throw it in the outpost and you’ll be able to find where the invisible enemies are roaming. Once you’ve defeated all the enemies, interact with the control panel in the center of the platform to capture it and complete the mission. Finally, collect the UNSC Audio Log which can be found on the floor next to a box.
