Edge

Edge is a multiplayer map originally developed for and intended for inclusion in Halo Online. In Series 7: Elite, the map was brought into the Halo 3 component of Halo: The Master Chief Collection.

Universe and lore
Edge is set within a Forerunner databank facility located in the face of a cliff on Partition. The facility is situated above a chasm with several waterfalls pouring down into its depths. Within the facility, Constructor Sentinels can be seen maintaining the databanks.

Layout
Edge is a reasonably small symmetrical map, consisting of two bases, each with four tunnels leading out of them. These tunnels emerge on either side of the map, in two large rooms, which are essentially reflections of each other. On one side, an Energy Sword can be found. The opposite room contains a gravity hammer and two Type-50 particle beam rifles.

Halo 3 variant
With the map's inclusion in Halo 3, the selection of weapons and equipment on the map have been reworked to fit the Halo 3 weapon sandbox. Notably, the central rocket launcher has been replaced with an overshield, the energy sword replaced with a sniper rifle and the gravity hammer replaced with a rocket launcher. Unique to Halo 3 in MCC, the map has seen the inclusion of Silenced SMGs.

Production notes
This map was one of many multiplayer maps developed and intended for inclusion in Halo Online. The map was included in the game's public release testing alongside Diamondback, Reactor and Icebox (among a few Halo 3 direct ports). The map was originally intended to release in Series 6: Raven of The Master Chief Collection, added into the game's Halo 3 multiplayer component alongside Waterfall. However, it was ultimately delayed as 343 Industries felt the map needed "fundamental improvements" before being released, with the map being added to The Master Chief Collection as part of Season 7: Elite on June 23, 2021.

Trivia
The Constructors on this map are capable of being destroyed.
