Halo: The Master Chief Collection has tons of collectibles and unlocks that are just waiting to be found. In this guide, the locations of every skull in Halo: Combat Evolved will be revealed. Obtaining all of the skulls will unlock the 20 Gamerscore ‘Headhunter’ achievement (Halo: Find and claim all Skulls in Halo: Combat Evolved.) Each and every skull has an achievement to earn when picked up. Reminder, the Halo: Combat Evolved skulls are only available while playing the Remastered mode (Default).
