Halo: Combat Evolved Anniversary skulls
From Halopedia, the Halo wiki
Halo: Combat Evolved Anniversary Skulls are game modifiers that will be featured in Halo: Combat Evolved Anniversary with the appearance of a human skull. Like in Halo 3, they must be hunted down within the campaign levels to gain access to them. The skulls and the effects will not be visible in Classic mode[1], and are also not visible or present in split-screen Co-op.
