Halo: Campaign Evolved
Halo Campaign Evolved Pillar of Autumn skull locations
Pillar of Autumn contains three skulls: Speed Limit, Magnified and Perspective. Collect all three plus the mission's terminal to earn the Clean Sweep achievement or trophy. Skulls emit a sound when you are close and are collected with the normal Interact button.
Speed Limit location#
Immediately after leaving the cryo pod, look at the raised platform above the door on your right. Enter the alcove with the cryo tank, use the slope behind it to climb onto the tank, then jump to the platform and follow it right to the skull.
Magnified location#
Continue toward the bridge until an Elite appears from the opening door. Pass the Marines' barricade and enter the room lined with weapon racks. Magnified is sitting on top of a rack to the left.
Perspective location#
After the Captain Keyes bridge cutscene, walk toward the two pilots seated at the front of the cockpit. Drop into the recessed space below them to collect Perspective. If you already finished the mission, Rally Point Bravo places you after the bridge scene.
Perspective switches normal play to an over-the-shoulder camera while scoped zoom still uses first person. Enable a collected modifier before starting a mission or rally point.
See the complete skull mission list, visit the Halo: Campaign Evolved guide hub, or use the crash troubleshooting guide if the mission is unstable.
