How to find this skull

Mission: Boarding Action

After clearing the first hangar, including the two Hunters, do not follow Johnson up the nearby slope. Cross to the opposite side from where you entered and drop down on the right to reach the door that was locked earlier. Follow the corridor as it spirals down, then pass through the unlocked doors across the bay. Malfunction is on the right-hand walkway in the next room.

After the hangar fight, cross to the opposite side and use the door that is now open.
