Halo Campaign Evolved, the impressive Unreal Engine 5 reimagining of the classic original, keeps the beloved tradition of hidden Skulls alive. These elusive collectibles are not just for completionists; they serve as powerful modifiers that can drastically alter your gameplay experience, introducing unique challenges or chaotic fun. If you are starting your journey and looking to master the first mission, our comprehensive guide will help you locate the three Skulls hidden within 'The Pillar of Autumn'.
Understanding the Skulls
Before diving in, remember that Skulls must be collected to unlock their respective modifiers for subsequent playthroughs. Whether you want to test your mettle or simply shake up the standard combat loop, finding these is essential.
1. The 'IWHBYD' (Inutile de Courir) Skull
Found in the very first room of the game, the cryo-bay. Once you gain control of the Master Chief, ignore the linear path for a moment. Instead, use the nearby shipping containers to jump onto the elevated platform on the right side of the room. The skull is waiting at the end of the walkway. Effect: This skull disables the player's sprint ability.
2. The 'Grunt Birthday' (Grand Format) Skull
As you proceed toward the ship's bridge and enter the BO2L sector, keep an eye on the environment. You will find the 'Grand Format' skull resting atop the massive power generators in this chamber. Effect: This modifier changes the Assault Rifle's magazine capacity to 60 rounds, reminiscent of the original Combat Evolved balance.
3. The 'Eye Patch' (Perspective) Skull
After your encounter with Captain Keyes where you receive Cortana, continue your objective path toward the bridge. Before exiting, look for an access ladder located between the pilots on the catwalk. Descending this ladder will reveal the final skull in the shadows below. Effect: This skull forces a third-person perspective, providing a completely different tactical view of the battlefield.
By collecting these three skulls, you will gain access to versatile gameplay modifiers that add immense replay value to your Halo Campaign Evolved experience.
