Halo Campaign Evolved Guide: How to Find All Skulls in 'Two Betrayals'
Unlock every secret in Halo Campaign Evolved! Discover the exact locations and gameplay effects of the 3 hidden Skulls in the 'Two Betrayals' chapter.

Mastering the Hunt in Halo Campaign Evolved
For veterans of the legendary franchise and newcomers alike, Halo Campaign Evolved—the stunning Unreal Engine 5 remake of the original 2001 masterpiece—brings back one of the most rewarding side activities: the hunt for Skulls. These elusive collectibles are scattered throughout the campaign, with three hidden in every main chapter and additional ones tucked away in the remake's exclusive bonus missions.
Once collected, these Skulls allow players to modify their game experience by activating 'modifiers' during subsequent playthroughs. These effects can range from hilarious gameplay tweaks to brutal challenges that completely redefine how you approach combat. In this comprehensive guide, we focus on the eighth chapter, 'Two Betrayals', providing you with the exact locations and the gameplay impact of its three hidden Skulls.
Location Guide: The 3 Skulls of Two Betrayals
1. Bad Luck
To secure the first Skull, it is recommended to start a fresh session of the 'Two Betrayals' chapter from Checkpoint Alpha. Your primary tool for this collection is the Banshee. Use the vehicle to fly toward the summit of the spire. Once you reach the top, exit the Banshee and look for a high ledge; the Bad Luck Skull is perched right there.
Pro Tip: If you have already unlocked the 'Acrophobia' Skull, you can use its effects to make reaching this elevated ledge significantly easier.
2. Black Eye
The search for the second Skull begins after you reach Checkpoint Charlie. From this point, head directly across the central bridge and follow the path until you reach the corner of the area. The Black Eye Skull is floating amidst a grim pile of Flood corpses and snow.
Because the environment is dim and the Skull blends into the carnage, we strongly recommend activating your flashlight to spot the shimmering collectible more easily.
3. Mythic
The final collectible in this chapter is tucked away behind a combat gauntlet. Before proceeding to destroy the second conduit indicated by your mission marker, locate the area where the Covenant are battling Hunters. Use a Banshee to fly to the platform of the adjacent spire.
Once on the platform, locate the terminal. While this terminal opens a door that is not required for the main story, it is essential for the Skull. Enter the structure, navigate through three successive corridor sections, and eliminate every enemy in each room to unlock the subsequent door. After clearing the final room of all hostiles, the Mythic Skull will appear on a central platform.
Understanding the Effects: What Do These Skulls Do?
Collecting the Skulls is only half the fun; the real challenge begins when you activate them in the menu. Here is how the Skulls from 'Two Betrayals' will alter your game:
- Bad Luck: This modifier significantly increases the difficulty of combat. Enemies will dodge your attacks more frequently, enter a permanent rage state, and will never retreat, making every encounter a fight to the death.
- Black Eye: This changes the core survival mechanic of the game. Your energy shields will no longer recharge automatically; the only way to restore your shields is by performing successful melee attacks.
- Mythic: A straightforward but brutal modifier that increases the total health of all enemies, turning every grunt and elite into a tank.
