In Halo Reach, you don’t need to run around the different maps of the game searching for Skulls since they are all immediately available from the beginning. Each one provides you with different effects if you turn it on before attempting a campaign session. We’ve prepared a Halo Reach Skulls List for you to check out before thinking about which skulls to activate for your gameplay.
Halo Reach Skulls List
Load up a game and you should get a screen with multiple tabs. Scroll to the right to the skull screen, select your skulls, press apply or accept at the bottom of the page. Then load up the mission.
If you are in the middle of a campaign mission and are about to beat said-mission, you cannot activate any skulls for the next mission. Instead, simply go back to the main menu after finishing the mission, and load the next mission again to choose the skulls. You cannot add any skulls during a mission, only at the beginning where you also chose your preferred difficulty and the time/score display.
These skulls act as Modifiers in Halo Reach that change the gameplay in interesting ways. They can either give you a boost if you are finding the game challenging to hamper you and boost your enemies to give you more of a challenge.
