Mastering Halo Campaign Evolved: Location and Effects of the 3 Skulls in '343 Guilty Spark'
Discover the exact locations and gameplay effects of all 3 skulls hidden in the 343 Guilty Spark chapter of Halo Campaign Evolved in this comprehensive guide.

Halo Campaign Evolved, the modern Unreal Engine 5 reimagining of the legendary original title, brings back the fan-favorite system of 'Skulls'. These collectibles serve as gameplay modifiers, allowing players to spice up their experience upon replaying missions. In the sixth chapter, '343 Guilty Spark', players can hunt down three specific skulls, each offering a unique twist to the gameplay.
Understanding the Skulls
Skulls in Halo are iconic modifiers that can either make the game significantly harder, introduce hilarious visual gags, or fundamentally alter AI behavior. To unlock them, players must navigate to specific, often hidden areas within the mission environment.
Locations of the 3 Skulls in '343 Guilty Spark'
1. The Fog Skull
To secure the Fog skull, restart the chapter from 'Rally Point Alpha'. As you progress, look for the Covenant landing craft. Instead of rushing forward, head left and climb the hill. You will find a set of tree roots; the skull is tucked away on a small mound of dirt behind them. This modifier disables your motion tracker, forcing you to rely solely on your eyes and ears.
2. The 'Ah, Bravo!' Skull
This skull is notoriously grim to obtain. During the sequence where you reunite with the squad escorting Captain Keyes, look for a specific Marine suffering from a panic attack. To force him to drop the 'Ah, Bravo!' skull, you are unfortunately required to eliminate him. This skull increases the detection range of enemies, making stealth significantly more challenging.
3. The Revenants Skull
Found towards the end of the level, this skull is hidden in the swampy marshland. Before clearing out the final wave of enemies, head towards the North direction on your compass. Search for a large, fallen tree resting against a rock formation. Scale the tree and collect the Revenants skull from the top of the rock. This skull enhances the danger level of Flood forms resurrected by infection entities.
Summary of Effects
By collecting these skulls, you can activate them in the pre-game menu to customize your next playthrough:
- Fog: Disables the HUD motion tracker.
- Ah, Bravo!: Increases enemy detection sensitivity.
- Revenants: Parasitic forms become much more aggressive and lethal upon revival.
