Halo Campaign Evolved skulls and where to find them
Overview & Key Takeaways
A guide to all skulls in Halo: Campaign Evolved and where to find them, along with a list of each skull and its description.
Skulls are collectibles in Halo: Campaign Evolved that can be used to modify your playthrough. There are a grand total of 42 skulls and 39 of them are hidden throughout the game's 13 levels. The other three are unlocked automatically once you find two skulls. 26 of these are legacy skulls, aka skulls that have featured in the Halo series before, while the remaining 16 are brand-new skulls. You'll need to collect all skulls to tackle the famous LASO (Legendary All Skulls On) challenge, and if you want to earn the Headhunter achievement/trophy.

Halo: Campaign Evolved skulls list
Skulls in Halo: Campaign Evolved are essentially gameplay modifiers. Some grant buffs, while others make the game considerably tougher. Meanwhile, others are there for pure comedic purposes. You can enable any skulls you've unlocked before starting a new campaign or specific mission from the level select option.
