'''Halo 4 skulls''' are game modifiers featured in ''[[Halo 4]]'' with the appearance of a [[human]] [[skull]]. The skulls are the same from ''[[Halo: Reach]]''. In addition, just like in ''[[Halo 3: ODST]]'' and ''Halo: Reach'', skulls are no longer easter eggs in-game, and can also be accessed in the [[campaign]] menu without claiming them in campaign levels.<ref name="hb101712">[http://blogs.halowaypoint.com/Headlines/post/2012/10/17/The-Halo-Bulletin-101712-.aspx '''Halo Waypoint''' - ''The Halo Bulletin 10.17.12'']</ref>

== List of skulls ==
=== Famine ===
Weapons drop much less ammo.{{Ref/Reuse|hb101712}}

=== Tilt ===
Enemy resistances and weaknesses are increased.{{Ref/Reuse|hb101712}} This also affects the player.

=== Mythic ===
All NPCs have doubled health.{{Ref/Reuse|hb101712}}

=== Catch ===
Enemies throw grenades more often.{{Ref/Reuse|hb101712}}

=== Black Eye ===
[[Energy shielding|Energy shields]] don't recharge unless the player [[melee]]s enemies.{{Ref/Reuse|hb101712}} The following actions also recharge energy shields:
* The '''RT''' attacks of the [[Gravity hammer (fiction)|Gravity Hammer]] and [[Type-1 energy sword|Energy Sword]]
* An enemy being in the Gravity Hammer's shockwave area of effect
* [[Boarding (gameplay mechanic)|Boarding/hijacking]] an enemy vehicle
* Punching (not boarding/hijacking) an enemy vehicle, manned turret, or [[Sho'riru-pattern Shade|Shade Turret]]
* Punching the [[Kmiro'sish-pattern Lich|Lich]]'s core, in any levels that feature Liches
* Deploying a [[M2705 regeneration field|Regeneration Field]]
* Betraying allies and punching them

The following missions feature scripted events that recharge the player's shields regardless:
* [[Forerunner (level)|Forerunner]] - Only on [[Easy]] difficulty, when [[John-117]] kicks the [[Promethean Knight]] away, and the latter teleports out of the scene, the player's shields will recharge.
* [[Infinity (Halo 4 level)|Infinity]] - When the player reaches the checkpoint "THE GUN SHOW", their shields will be fully restored.
* [[Shutdown]] - When the player goes to the left tower and enters the energy field, their shields will be drained and recharged seconds after, even with the Black Eye skull on. This is missable, however, if the player chooses to skip the two main towers and fly to the final tower.

Unlike past ''Halo'' games, the low shield beep and shield down beep sound effects are removed when the Black Eye skull is active.

=== Tough Luck ===
Enemies always go berserk, always dive out of the way, and never flee.{{Ref/Reuse|hb101712}}

=== Iron ===
On campaign solo, player death results in the mission restarting. On [[cooperative play]], player death results in reversion to previous checkpoint.{{Ref/Reuse|hb101712}}

=== Thunderstorm ===
Major upgrade to the capabilities of enemies.{{Ref/Reuse|hb101712}} Sangheili, excluding [[Sangheili Zealot|Zealots]], will always appear as [[Sangheili Warrior]]s. Unggoy will always appear as [[Unggoy Heavy|Unggoy Heavies]]. [[Kig-Yar]] will always appear as [[Kig-Yar Heavy|Kig-Yar Heavies]]. [[Promethean Crawler]]s will always appear as [[Alpha Crawler]]s. As with previous games, specialists, such as Rangers, are not affected. [[Promethean Knight]]s and [[Promethean Watcher]]s are also immune to the Thunderstorm skull's effects.

=== Cloud / Fog ===
[[Motion tracker]] is disabled.{{Ref/Reuse|hb101712}}

=== Cowbell ===

=== Grunt Birthday Party ===
[[Headshot]]ting an [[Unggoy]] results in an explosion and sounds of cheering people.{{Ref/Reuse|hb101712}} The following weapons can trigger this effect:
* [[M6H magnum|Magnum]]
* [[BR85HB battle rifle|Battle Rifle]]
* [[M395 DMR|DMR]]
* [[SRS99-S5 AM sniper rifle|Sniper Rifle]]
* [[Vostu-pattern carbine|Carbine]]
* [[Zubo-pattern beam rifle|Beam Rifle]]

== Trivia ==
In the level [[Forerunner (level)|Forerunner]], the animation of the Promethean Knight leaping onto John is changed if the level is played with the Black Eye skull on (except on Easy). In the alternate animation, the Knight shoots him after being kicked off to ensure the player's shields don't recharge after their melee.
