Edge

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

Overview
The map is a symmetrical map that is set in a Forerunner databank which is entirely set into a cliff face. It is reasonably small, 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, and the room is open with a view of several waterfalls descending into a chasm, above which the map is situated. The opposite room contains a Gravity Hammer and two Type-50 particle beam rifle, and instead of a landscape, its view is of the databank, maintained by flocks of Constructors.

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 Season 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.
