Skulls are a staple of the Halo series, which is why it comes as no surprise that 42 Skulls can be collected across 13 missions in Halo Campaign Evolved . You can use Skulls to add unique modifiers to each mission , adding further replayability to their iconic designs! If you have collected a few skulls throughout the story , you might be curious how you can use them, which we'll explain in detail below. If you're looking to get all 42 skulls, make sure you click the guide above! This will guide you through all 13 missions to get every skull within them. You can also click here to get every terminal if you want to complete your collectibles. How to Activate Skulls in Halo Campaign Evolved Close When you collect a Skull, you can head to the main menu and select Campaign. From here, you will need to select New Game. While this will override the progress of your current solo campaign, it's the only way to use Skulls, and you can select any mission and checkpoint you've unlocked to resume your progress. After selecting New Game, choose any of the difficulty options provided. Once that's done, you can choose your mission and the rally point (checkpoint), which then brings you to the Select Skulls screen. From here, you can select any of the Skulls that you have unlocked, and then just click "Apply & Start" to begin. There is no way to remove these skulls unless you once again click New Game like you did to activate the skulls in the first place.
