Skulls locations | Halo 5: Guardians

Skulls are modifiers in Halo 5: Guardians that add challenges to the game. They are well hidden collectibles scattered throughout many missions. Skulls can add modifications to the gameplay or change player’s and enemy’s abilities. During co-op gameplay any unlocked collectibles including skulls will be granted to all players present at the time. Collecting skulls unlocks two achievements: Gravedigger and Gravelord.
