Repository Collectibles

Find the Grunt Birthday Party Skull and UNSC Audio Logs in Halo Infinite's Repository mission. Follow our guide for detailed steps on collecting all items.

This guide details how to find all collectibles within the Repository mission in Halo Infinite, including the Grunt Birthday Party Skull and UNSC Audio Logs.

1. Defeat Sentinels: At the start, defeat Sentinels patrolling the bridges. Use the Sentinel Beam and ammo crates.
2. Interact with Terminal: Reach a dark room with a terminal. Interact to trigger a cutscene, then defeat the Banished that emerge from the now-unlocked blue doors.
3. Transfer Power Seed: Take a power seed from one room and use the Grappleshot to transfer it to the crucible in the other room. Be prepared to fight Sentinels that attack during this process.
4. Access Skull: After placing the power seed, an energy barrier will deactivate. Follow the quest marker to a room with a large window.
5. Defeat Elite Brutes: In the skull's room, you'll be locked in until you defeat four Elite Brutes wielding Energy Swords and Active Camo. Use Threat Sensor and grenades, focus fire on one Brute at a time, and use the Grappleshot to grab an Energy Sword if needed.
6. Find UNSC Audio Log 1: Continue following objective markers. After a cutscene near an inactive gravity lift, the lift activates, allowing you to proceed. The audio log "The Weapon" is unlocked during this cutscene.
7. Find UNSC Audio Log 2: Ascend the gravity lift and defeat enemies. In a larger room with two unpowered crucibles, find power seeds in nearby rooms beyond doors and down ramps. Each room contains tough Elite Brutes. Defeat them to retrieve the power seeds.
