Assembly

Assembly is the official name for the map that was announced in the Bungie Weekly Update (8/22/2008). It was originally planned to be in the Heroic Map Pack, then the Legendary Map Pack, but was replaced due to the fear that it wouldn't be finished on time. At the current time there is no known release date for this map.

Design
The map, as seen by fans at PAX 2008, is based inside a Covenant Scarab factory. When looking overhead, Scarabs can be seen moving by some kind of automated gravity beam. As such, the area outside the level is immense. The map itself is bowl shaped, sloping toward the centre. This bottom floor is dotted with pillars and walls for cover. It has an outer rim with four bridges that connect to the two-story centre structure, and has small structures on the rim intended as high ground. It appears to be symmetrical. Line of sight is generally open, with mid-range combat being optimal when on the second level. However, within the centre structure and around the pillars that dot the bottom level, close combat is possible.

The map is focused on competitive playing, as it is multi-story arena-style map. It features two "somewhat enclosed" bases, with one-way mirrors on the second floor (like those in interrogation rooms), where players will be able to look out, but players outside will be unable to see in.

Mystery
Before Assembly was removed from the Legendary Map Pack, it was stated that one of the maps would expand upon the Scarab-Hunter mystery. In a recent Weekly Update, it was stated that, "One base of this open-air arena could end up getting called 'Energy side' and another call-out could end up 'Hunter side'", so it's possible that this was the map they were referring to. Adding to this mystery, Luke Smith posted on a thread on the Bungie forums that "the name Assembly is extremely appropriate." It would be found that this comment came after the release of the name of the map in the Weekly Update on the same day. His comment would refer the fact that Scarabs are assembled within the facility. The Scarabs are carried along an assembly line, with the playable area of the map being one of the machines that constructs the Scarabs.

Skull
The crest of the hidden skull on this level appears to be that of the Lekgolo worms referring to the Scarab assembly line.

Trivia

 * In the images, fog can be seen in the distance if you are far enough away from a structure. Similar fog can be seen on the Halo 2 level High Charity near in the parts with Flood.
 * The former name of the map, Purple Reign, could of been a homonym with the TNT firework "Purple Rain", it could also be linked as a tongue in cheek reference to the song "Purple Rain" from the artist Prince, but it is most likely referring to the dominance of the colour purple on the map.
 * Assembly was first announced to be part of the Heroic Map Pack (while at that time it was called Purple Reign instead), which was soon replaced by Foundry, and then announced to be part of the Legendary Map Pack, but replaced by Blackout, which shows that this map project has been going on for quite a while in Bungie. This long delay of release may possibly mean that the map has a very complex design layout for game play.
 * Although not a true screen shot, a pen rendering of the map was featured in the Bungie Weekly Update on July 25, 2008.
 * This map will be released with Orbital, Citadel, Heretic, Sandbox, and Longshore in the Mythic map pack.
 * The map was originally intended for Slayer based games, but objective games are described as playable and frantic.
 * Assembly will finally tell players what the Scarab and Hunters have in common.
 * A Bungie Weekly Update has released several screen shots for those who are unable to reach PAX 2008.
 * The rumours of there being a Hunter side, and an energy side have been confirmed.
 * This map contains a hidden skull. Locating the skull rewards the player with the 'Assembly Skull' achievement.
