If you are looking for all three hidden Skulls on The Most Dangerous Game campaign mission in Halo: Campaign Evolved, then you'll need to solve minor environmental puzzles, search alien spires, or use specific movement Skulls to reach hazard zones.

This guide covers where to find the Recession, Temperamental, and Ghost Skulls so you can collect them all without hassle.

Requirements and Gameplay Modifiers

Before starting, keep a few mechanics in mind. If you want to make your run much easier while searching for Skulls, you can adjust your custom damage modifiers in the game menu in Halo: Campaign Evolved

Navigate to gameplay settings and modify preset 01. Max out your shields, damage resistance, output damage, and ammo clips.

Activating these options will not block Skull spawns, and it allows you to fly through fire pits, clear out high-value targets, and explore hazardous areas without taking damage.

How to Get the Recession Skull

The Recession Skull requires interacting with environmental objects near a large sealed entrance.

Advance through the level until you reach the bridge area. Turn around to face a massive locked door flanked by several braziers.

Take a good look at the braziers, and you will see the plasma battery inside each one.

Shoot every plasma battery to trigger the unlocking mechanism on the main door. Once the door opens, step inside the newly accessible room to pick up the Recession Skull.

How to Get the Temperamental Skull

The Temperamental Skull is tucked inside a central structure after a major combat arena in Halo: Campaign Evolved

Progress until you enter a circular outdoor arena where a high-value target Elite is watching the battlefield from above.

Eliminate all enemy forces to secure the area, then make your way to the top-middle Covenant spire. Head inside the center of this spire to find the Temperamental Skull resting on the floor.

How to Get the Ghost Skull

The Ghost Skull requires activating the Acrophobia Skull prior to launching the mission so you can fly through the air in Halo: Campaign Evolved

Just past the Banshee bridge section, you will enter a large open arena. Pass through the main entrance doors, immediately look to your left, and use your flight capability to navigate straight into the active fire pit. The Ghost Skull is sitting right inside the center of the flames.
