If you want to complete your collection in Halo: Campaign Evolved and get the Headhunter achievement, then you need to find all of the hidden Skulls in Heavy Burden.

This mission hides three distinct collectibles in different areas, ranging from catwalks to dark corners. Here is how to grab every single one without missing a beat.

Halo: Campaign Evolved Guide Eye Patch Skull Location

Eye Patch Skull

You can pick up the Eye Patch Skull early on in Heavy Burden when you reach the first major bridge area in Halo: Campaign Evolved.

Instead of crossing the main bridge, turn toward the set of doors on your left. Walk through these doors to step out onto the catwalk. Run all the way to the end of the catwalk. Look to your right, and you will see the Eye Patch Skull sitting there waiting for you.

Grunt Birthday Party Skull

The Grunt Birthday Party Skull sits roughly halfway through your run inside a massive white and gold room.

Once you enter this chamber, head to the left side of the room. Look for the middle platform and jump directly into the brazier located on it. From inside the brazier, leap onto the nearby rock pillar at the top. You will find the Grunt Birthday Party Skull resting right on top of that pillar.

Efficient Skull

The Efficient Skull is the third and final Skull on Heavy Burden, and you can grab it during the gondola section near the end of the mission in Halo: Campaign Evolved.

Play through the gondola segment until you hit the final checkpoint area with platforms running along both sides. Jump onto the left platform and run to the very back left corner. The Efficient Skull is resting right on the ground in that dark area.
