'''Level''': [[The Silent Cartographer]]

'''Location''': At the end of the tunnel on the ceiling in the Security console building (Warning: Grenade jump necessary.)

-Unlike skulls in other games, which must be picked up, the ''Anniversary'' skulls are collected by walking over them. In the original ''Halo: Combat Evolved Anniversary'', once collected, the skulls disappear permanently. In ''[[Halo: The Master Chief Collection]]'', the skulls reappear every time a mission is replayed. During updates released as part of the [[MCC Insider Program]], the ''Master Chief Collection'' version of ''Halo: Combat Evolved Anniversary'' now has several additional skulls not implemented in the Xbox 360 version of the game.
-Unlike other games, skulls will spawn on any difficulty, instead of certain difficulties such as Normal or higher.

 ==Trivia==
-[[File:Grunt Funeral Skull.png|thumb|100px|Grunt Funeral skull as it appears in the menu screen in ''Anniversary''.]]
+*The description for the Boom skulls advises "Light fuse, run away." This is a reference to the second chapter of [[The Maw]].
-*The Grunt Funeral skull is available to all players in ''Halo: The Master Chief Collection''.
-*When playing co-op in the original ''Anniversary'' whether or not the skulls appear depends on whether Player 1 has claimed them yet. If Player 1 has already collected a skull it will not appear, regardless of whether or not Player 2 has collected it. Thus when playing co-op it is important that a player who still needs to unlock skulls plays as Player 1, and a player who has already unlocked the skulls is Player 2. In ''The Master Chief Collection'' the skulls appear every time regardless of whether one or both players have already collected them.
-*Unlike in [[Bungie]] games, players can still revert to their last checkpoint when using the Iron skull.
-*If both the Piñata and Grunt Funeral skulls are active, Grunts will not drop grenades when meleed. The Piñata skull remains in effect for all other enemies.
-*The description for the Boom skull advises "Light fuse, run away." This is a reference to the second chapter of the level ''The Maw''.
-*The Bandanna skull is a reference to the [[metalgear:|''Metal Gear'' franchise]], in which every game has an unlockable bandanna that grants the player infinite ammunition.
-*Unlike previous iterations, the Grunt Birthday Party skull can be set off by headshots from non-precision weapons (i.e. Assault Rifle, Plasma Pistol, etc). It merely requires that the final fatal shot strike the Unggoy's head.
-*This is the only ''Halo'' game (other than ''[[Halo Wars]]'', ''Combat Evolved'' and ''[[Halo: Spartan Assault|Spartan Assault]]'') that does not feature the IWHBYD skull.
-*According to one of the [[343 Sparkast]]s, there was a skull that was cut from the final game. Its effect was that weapon sound effects would be replaced with 343 employees saying the sound, such as "bang".
