The games in which the skull is available are listed below each skull. Pre-order skulls are marked with ¹ and 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. Skulls marked with ² were not available in the original release of the games, but were implemented via updates in the MCC Insider Program. The Acrophobia skull was added into the game for Halo 3 for the release of Halo 3 on PC. The Acrophobia can only be unlocked for use by completing a seasonal challenge to kill 343 flying enemies in Halo 3, between July 14 and July 29, 2020. It was unlocked globally after July 29, 2020.
