Boarding Action is the 1st Bonus Mission in Halo: Campaign Evolved. In this Halo Campaign Evolved guide, we'll reveal a Boarding Action walkthrough that documents where to find all the Collectibles.

Halo Campaign Evolved: Boarding Action Walkthrough - Skulls, Terminals

Halo Campaign Evolved: Boarding Action Walkthrough 1

There are 3 Skulls and 1 Terminal to find in Boarding Action. Below we have documented where to find them all in the order you would naturally encounter them, as part of our Halo Campaign Evolved guide.

Skull #1: Malfunction

  • As you progress through the mission, you'll eventually reach an area where you fight two heavily armoured Hunters, all in white
  • Once they're dead, go right instead of following the objective marker
  • Drop down to the area below where the Covenant dropship is, then go through the door in front of you
  • Follow the path behind the turret here to find the Skull on the ground

Skull #2: Johnny Ammo Seed

  • You eventually reach a palace-esque part of this mission, and in one room, Sgt. Johnson will comment on it being like a training room — to make it easier to identify, there's also a purple cylinder above you going horizontally
  • Once you've killed all the Covenant, go up to the second floor and then turn back to go where you've just come from
  • In the back are two exits, one going left and the other right
  • Take the left exit, and you'll be led to the top floor of the area you were previously in
  • Defeat the enemies, then go out onto the ledge to find the Skull in the middle of the path

Skull #3: Leadhead

  • When you're working your way to the upper decks of the Triumph of Tolerance, you'll reach a room where you need to clear out the waves of Covenant before Sgt. Johnson can activate the grav lift
  • Once they're all dead, go through the door in the back-left corner
  • Follow the corridor to find the Skull at the end

Terminal #1: The Path

  • At the top of the grav lift, turn around instead of following the objective marker
  • Go through the door in the back-right corner of the room and the Terminal will be on the other side
