''This article is about the level. For other uses, see here''

The Mythic Map Pack is being released first as part of Halo Wars Limited Edition. At some point after this, those 3 maps (Assembly, Orbital, and Sandbox) will be available for purchase on Marketplace like the other map packs, date and price TBA.

Anything further than that is conjecture.

Citadel is an upcoming Halo 3 map that may be included in the second part of the Mythic Map Pack, It will be shipped in Fall 2009 with Halo 3: ODST along with Longshore and Heretic.

Skull
This map has a skull for the multiplayer achievements. When found it unlocks the achievement, Citadel Skull. It has an image on the skull that resembles the Citadel in the Campaign level, The Covenant.

Trivia

 * This map is rumored to be a Forerunner map because of the Forerunner symbol on the Citadel Skull achievement.
 * This map could be based on the end of the level The Covenant as where Truth, attempted to activate the Halos because it's called "The Citadel", but may be a re-modeled "Citadel" instead.
 * It is possible this map will not ship with the Mythic Map Pack in February.
 * This may also be another map similar to Construct, but due to the Shotgun Spree achievement, it may be more of a close-quarters map.
