Skulls & Terminals

Pick up your very first skull — the Speed Limit skull sits at the far end of the opening platform in Pillar of Autumn, so this usually pops within minutes of starting.

A milestone on the way to all 39 — you will pass 22 skulls naturally while sweeping the missions for the per-mission trophies below.

Grab every one of the 39 skulls across the 13 missions (3 per mission). You need all of them before you can attempt MYTHIC (LASO), so this is a mandatory sweep. Use the per-mission entries below to tick each set off.

Activate the 1 UNSC Terminal hidden in each of the 13 missions. They are usually tucked off the main path — check the per-mission entries below and interact with each terminal to log it.

The collectible Gold: every skull and terminal in the whole game — all 39 skulls plus all 13 terminals. It unlocks once every per-mission set below is complete, so clearing this page clears the Gold. There is nothing hard about it beyond thoroughness.
