Boarding Action has three Skulls to collect in Halo: Campaign Evolved: Malfunction after the two-Hunter fight, Johnny Ammo Seed in the Elite training room, and Leadhead in the grav-lift arena side corridor.
Boarding Action hides its Skull pickups just off the objective route, so the main trick is knowing when to stop following the marker. Use the table first if you only missed one Skull, then follow the timestamped pickup route for the exact detour.
Boarding Action Skull checklist
| Skull | Location cue |
|---|---|
| Malfunction | Past the standing turret after the mid-mission two-Hunter fight. |
| Johnny Ammo Seed | On the upper curved overlook in the sandy Elite training room. |
| Leadhead | At the end of a left-side corridor off the grav-lift arena. |
These are the three Skull collectibles in Boarding Action, and they appear in natural mission order.
How to get the Malfunction Skull in Halo: Campaign Evolved
KEY!Start this detour shortly after the fight with the two Hunters around the middle of Boarding Action.
STEP 1/6
Reach the two-Hunter fight
Push through the level until you defeat the pair of Hunters.
STEP 2/6
Ignore the upward route
When your ally heads upward, turn around instead of following him.
STEP 3/6
Face the doorway opposite your entry route
Backtrack to the spot where you came up and line up with the door directly opposite that path.
STEP 4/6
Enter the side room
Go through the door and move into the area with the standing turret.
STEP 5/6
Pass the turret
Follow the route around past the turret and cross the small bridge.
STEP 6/6
Pick up Malfunction
Grab the Malfunction Skull from the floor at the end of the short path.
Pause before every objective-only route in Boarding Action; each Skull sits in a side path you can miss by following the marker too quickly.
How to get the Johnny Ammo Seed Skull in Halo: Campaign Evolved
The second Skull is in the large sandy Elite training room with the horizontal tractor beam.
- Enter the Elite training room — Look for the open room with sand across the floor and the large horizontal tractor beam overhead.
- Clear the room first — Defeat the enemies in the lower room before going for the Skull.
- Avoid the tractor beam route — Do not take the objective path through the tractor beam, since that route can move you past the collectible path.
- Return above the entry point — Head back toward the balcony directly above where you entered the room.
- Use either side door — Take the left or right door, as both lead toward the upper area.
- Clear the upper enemies — Deal with the enemies on the upper route before stepping out for the pickup.
- Collect Johnny Ammo Seed — Pick up the Johnny Ammo Seed Skull from the upper curved ledge overlooking the room.
How to get the Leadhead Skull in Halo: Campaign Evolved
Leadhead is found in the arena where Covenant waves arrive around the grav lift.
- Reach the grav-lift arena — Continue until Covenant enemies begin arriving in waves around the grav lift.
- Eliminate every wave — Keep fighting until the arena calms down and the remaining enemies are cleared.
- Face the left-side doors — With the grav lift ahead, look to the left-hand side of the arena.
- Skip the grav lift for now — Do not ride the grav lift yet, even when the mission points you that way.
- Check the back-left route — Move toward the back-left side and use the left-side door, not the nearby wrong door.
- Follow the corridor to the end — Continue through the corridor until it dead-ends at the final Skull.
- Pick up Leadhead — Grab the Leadhead Skull to finish all three Boarding Action Skulls.

Skull effects and the Boarding Action Terminal
| Skull | Effect |
|---|---|
| Malfunction | Each respawn randomly removes part of your HUD. |
| Johnny Ammo Seed | Reloading discards the ammo left in the magazine. |
| Leadhead | Headshots no longer give bonus damage or instant kills. |
KEY!Skulls are not just collectibles; once collected, they can be activated as gameplay modifiers. For this mission, the known effects are short enough to keep handy while you decide which ones to use.
The Boarding Action Terminal is a separate collectible, not one of the three Skulls. It comes after the Leadhead route and the grav-lift progression; achievement wording around Souvenirs has been inconsistent, so collect both the three Skulls and the Terminal while you are in the mission.
Frequently Asked Questions
How many Skulls are in Boarding Action?
Boarding Action has three Skulls: Malfunction, Johnny Ammo Seed, and Leadhead.
Can you collect the Boarding Action Skulls before the main missions?
Yes. Boarding Action is the first prequel mission, and you can tackle the prequel missions before the main missions, though they still have to be completed in order.
Do you need to clear enemies before grabbing the Skulls?
For Johnny Ammo Seed and Leadhead, clear the nearby enemies first so the route is stable. If you die after picking up a Skull, grab it again before moving on.
Where is the Boarding Action Terminal compared with the Leadhead Skull?
The Terminal comes later than Leadhead. Get Leadhead from the side corridor first, then continue through the grav-lift progression to reach the Terminal route.
