Forge World

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

Description
The canyon is a direct remake of Blood Gulch from Halo: Combat Evolved. 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 thought to be a simple remake of Blood Gulch. The true nature of this map was revealed in the Forge World ViDoc on July 22, 2010. It actually began development as five separate maps, which were then combined. Forge World makes use of a new system in the game's engine called impostering that 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 either end, an open field inbetween, and a drying river running through it. The level supports vehicles and is recommended for larger team games. 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 in the object menu to designate which team it belongs to.

The island area is roughly symmetrical, with a large rock formation in the center and a small bay on one side that molds this area into a "U-shape". There is also a small tunnel that cuts through the center rock. The enclosed area is reminiscent of the Crypt from Sandbox. Instead of stone, however, it 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 for the popular Halo 2 map Ascension, takes place here. In the new ViDoc, at approximately 5:09, a newer version of Halo 2's Warlock (or Halo: Combat Evolved's Wizard) can be seen as well as a Blackout (Lockout in Halo 2) remake at 5:48

Trivia

 * It is currently the only known level in Halo: Reach to take place on a Halo installation.
 * Because it has been confirmed that the events of Halo: Reach take place solely on the planet Reach, it can be assumed that this map will not be integrated into the Campaign like most, if not all, of the others.
 * This is the largest Halo multiplayer map up to date.
 * The Forge budget 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 Grifball court included in Forge World.
 * It is confirmed that up to 4 Scorpions and 8 Falcons can be placed in the map.
