Assembly

Purple Reign is the nickname for a map that was announced in the Bungie Weekly Update: 10/26/2007. This map was originally planned to be in the Legendary Map Pack, but was replaced by Blackout due to the fear that it woulddn't be finished on time, but will now be included in the following map pack. It has been stated that it will be symmetrical or semi-symmetrical with the middle of the map being higher than the rest. According to the Bungie Weekly Update: 1/4/2008 the map will be an entirely new map. The map is supposed to be full of mid to long range weapons, and from what the update states it appears there will be multiple floors. This map is based outdoors.

Design
Due to the name, possible origin, and structure of the level, some fans have speculated that this map will be set on a structure of Covenant origins, with the map possibly taking place on the ship similar to the Unyielding Hierophant or Pious Inquisitor, which has lead many to believe that Purple Reign could be a possible remake of Halo 2 multiplayer map Midship. However, this is unlikely, as it is stated that it is a completely new map.

It is said to be nearly perfectly symmetrical, with the mid section being higher than the rest of the map. It is also said that it based outside with "some excellent line of sight and well thought-out verticality problems and opportunities. Bridges make short work of long open sections and a central hub is sure to be fought over".

The map is focused on competitive playing, as it multi-story arena styled 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 what's inside.

The arena is designed like a bowl, with the floor slighly concaved and dotted with columns for cover. Four elevated walkways converge in a small bi-level center structure that sports a cache of important items.

The map is originally intended for Slayer based games, but objective games works well, but is described as frantic

Mystery
Before Purple Reign were 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 natural to believe that Purple Reign is the map they spoke of.

Tactics

 * The map is too confined for genuine cat and mouse activity at those chokepoints and a warren of claustrophobic lower areas makes high ground and control essential.
 * There are several ways to get up top of the middle section, from careful jumps to spiraling ramps.
 * The map is said to be a perfect map for Battle Rifle duels, and for stucking people hundreds of yards away.

Trivia

 * Bungie confirmed that this map does not reference Prince's song or the movie Purple Rain.
 * The screenshot available has been available for many weeks, long before the map was cancelled for the Legendary map Pack. Link
