Introduction
This is a guide to getting all six hidden skulls on the Mythic Maps: Sandbox, Assembly, Orbital, Heretic, Citadel, and Longshore. These skulls have no effect on gameplay (unlike campaign skulls). However, there is a 25 point achievement for finding three of the skulls, meaning an easy 75 points if you get all three. The skulls cannot be accessed without the use of Forge mode.
Even though the description for the Brainpan Vidmaster Challenge says you need to claim all the skulls on the Mythic Maps, getting all three skulls will not give you Brainpan. In order to acquire Brainpan, you will also need the skulls from Longshore, Heretic, and Citadel, not just the skulls from the Halo 3 Mythic Map Pack. Currently Longshore, Heretic, and Citadel are only available with Halo 3: ODST.
