Finding every hidden Skull in Halo: Campaign Evolved can take a lot of patience. If you are hunting down collectibles, the level Assault on the Control Room holds three different Skulls: IWHBYD, Angry, and Cowbell. Here is how you can find all three without getting lost.

IWHBYD Skull Location

You can grab the IWHBYD Skull early in the mission once you get your hands on a Scorpion tank.

Drive the Scorpion across the bridge into the massive, open ice cavern. Instead of moving forward, take a left turn toward the large frozen waterfall. Drive the tank all the way up against the base of the waterfall in Halo: Campaign Evolved.

To reach the Skull, climb onto the turret of the Scorpion. From there, jump up into the small rock crevice along the cliff face. The IWHBYD Skull sits right inside that gap.

Angry Skull Location

The Angry Skull is further into the level in an outdoor valley that usually has several Shade Turrets scattered around.

Clear out the enemies in the area and look for three large Forerunner struts sticking out from the terrain. Walk around to the backmost strut in Halo: Campaign Evolved.

You need to climb up the incline of this structure all the way to the top platform. You will find the Angry Skull sitting right at the highest point.

Cowbell Skull Location

The final Skull in this level is Cowbell, which you can find near the end of the mission right before you reach the Ziggurat.

When you step out onto the final light bridge, ignore the Banshees and do not walk into the doorway on the far cliff face.

Instead, look down into the trench on the left side of the bridge structure. Jump down onto the sloping buttress below, then walk under the bridge itself. The Cowbell Skull is resting on a small mound of snow tucked underneath the bridge in Halo: Campaign Evolved.
