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.
