'''Skulls''' are gameplay modifiers with the appearance of a [[human]] [[skull]] featured in ''[[Halo: The Master Chief Collection]]''. Like in ''[[Halo 3: ODST]]'', ''[[Halo: Reach]]'' and ''[[Halo 4]]'', the skulls are no longer easter eggs in-game, and can also be accessed in the [[campaign]] menu without claiming them in campaign levels. A total 38 skulls are included in the collection, including several unique additions to ''[[Halo 2: Anniversary]]''.<ref name="your journey">[https://www.halowaypoint.com/en-us/community/bulletins/the-halo-bulletin-your-journey-begins '''Halo Waypoint''': ''The Halo Bulletin: Your Journey Begins'']</ref>

Skulls in ''The Master Chief Collection'' are divided into two categories: Scoring and Non-Scoring. Scoring skulls increase the challenge and reward players with higher score multipliers or bonuses to base enemy values when turned on. Non-Scoring skulls can either be neutral, such as Grunt Birthday Party, or in cases of cheat-like skulls, have a score multiplier of zero. Zero multiplier skulls like Scarab disqualify level times and scores from being recorded on the leaderboard and disable score and time-based achievements.{{Ref/Reuse|your journey}}

==List of skulls==
The games in which the skull is available are listed below each skull. Pre-order skulls are marked with ¹ and were unlocked globally on December 12, 2014. With the exception of these as well as the Swarm skull, all other skulls are unlocked from the start.{{Ref/Reuse|your journey}} Skulls marked with ² were not available in the original release of the games, but were implemented via updates in the [[MCC Insider Program]]. Skulls marked with ³ are "experimental"; starting a level with one of these skulls activated will result in a pop-up message warning "''You have turned on an experimental skull which may produce unexpected scenarios or hinder your ability to complete this mission. Experimental skulls may be disabled to return the game to a normal state.''"
The Acrophobia skull was added into the game for ''Halo 3'' for the release of ''Halo 3'' on PC.{{Ref/Site|D=01|M=6|Y=2020|URL=https://www.halowaypoint.com/en-us/news/mcc-development-update-june-2020|Site=Halo Waypoint|Page=MCC Development Update - June 2020}} The Acrophobia could originally only be unlocked for use by completing a [[season]]al [[Challenges/Halo: The Master Chief Collection|challenge]] to kill 343 flying enemies in ''Halo 3'', between July 14 and July 29, 2020.{{Ref/Site|D=01|M=6|Y=2020|URL=https://store.steampowered.com/newshub/app/976730/view/2595712846344485885|Site=Steam|Page=Halo 3 Celebration}} It was unlocked globally after July 29, 2020.

==Trivia==
* The description of the Acrophobia skull is a reference to [[The Truth and Reconciliation]] from [[Halo: Combat Evolved]]. where in the opening cutscene a marine says "The Corps issued me a rifle, not wings.".
* The Jacked skull will also prevent players from using mounted turrets. Unlike vehicles, turrets cannot be hijacked, therefore the skull renders them entirely unusable, though [[support weapon]]s in ''Halo 3'' and ''ODST'' can still be picked up and carried once they have been dislodged from their mounts.
