Forge World

Forge World is a new map in Halo: Reach, and is the largest map in the series' history. Set on a Halo Ring, Forge World allows for the most flexible Forge editing to date, allowing players to create entire maps within the larger map itself.

Description
Hemorrhage is a direct remake of Blood Gulch from Halo: Combat Evolved, combined with Coagulation from Halo 2. It was first revealed to the public through a Red vs. Blue public service announcement (requested by Bungie in celebration of Bungie Day 2010), and was originally thought only to be remake of Blood Gulch. The true nature of this map was revealed in the Forge World ViDoc on July 22, 2010, at ComicCon. It began development as five separate maps, which were then combined when Bungie realised that their engine could handle the processing power needed to do this without negatively affected gameplay. Forge World makes use of a new system in the game's engine called 'impostering', which allows very distant objects to be drawn cheaply. It is a giant map consisting of five distinct areas: the canyon area (which is modeled after Blood Gulch), an island, an enclosed space, a small cliff area, and the rock (a tall, corkscrew-shaped island, based loosely off of Ascension).

The canyon is set in a semi-enclosed, symmetrical canyon with a base at both ends, an open field inbetween, and a drying river. It supports vehicles and is recommended for larger teams. Other than the environmental changes, this area of the map is very faithful to the original Blood Gulch, with even the simplest nooks in the canyon walls being remade. The section itself is larger than the original Blood Gulch map, and possesses teleporters reminiscent of those from the maps Cold Storage and Gemini. The bases themselves are actual objects placeable and removable through Forge, and can be given a red or blue theme to designate which team it belongs to.

The island area is roughly symmetrical, with a large rock formation at the center and a small bay on one side that molds this area into a "U-shape". There is a small tunnel that cuts through the center rock. The enclosed area is reminiscent of the Crypt from Sandbox and appears to be made of Forerunner alloys. The "pocket" is a roughly rectangular grassy patch about the same size as the the Crypt, but is positioned on the edge of a cliff with the lake below. The "rock" is a tall spiraling column of rock stretching out of the lake. Pinnacle, the remake of Ascension, takes place here. Remakes of Warlock and Lockout can be seen as well.

Trivia

 * Bungie confirmed that the events of Halo: Reach take place solely on planet Reach, and so this map will not be integrated into the Campaign.
 * The Forge budget on this map is 10,000.
 * It seems possible to recolor vehicles according to team (eg, blue mongooses, red Warthogs). This capability was demonstrated at ComicCon.
 * It is confirmed that there will be a Griffball court included in Forge World.
 * It is confirmed that up to 4 Scorpions and 8 Falcons can be placed in the map.
