Skull Locations
Eye PatchAll aim assist disabled
Up on the upper walkway of the designated room: at the very edge of the platform, beside the door two purple-armored Elites emerge from - kill them and collect.
Grunt Birthday PartyHeadshot Grunts explode in confetti and cheers
In the grand atrium on the way back to ODST Williams after taking the data: on top of the decorative rock.
EfficientKilling enemies at full health drops extra ammo
Late in the mission, after the Covenant tram loses power and you restore it: cross one more bridge to the final stretch with platforms on both sides - skull in the far corner of the left platform.
Terminal

After the bridge cutscene, drop to the bottom level, go through the green door and the armory to the final room - behind the cabinet on the left. See all 13 terminals and their lore →
Legendary Tips
- Melee-execute sleeping enemies to save ammo (community).
- Fuel-rod Elites are the priority kill in every room (community).
- In the Seraph, run the rapid plasma beam (it shows a lead indicator) plus lock-on fuel rods; strip the turret grids before chasing escorts (community).
