Forge World

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

Description
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 thought to be a only a remake of Blood Gulch. The true nature of this map was revealed in the Forge World ViDoc on July 22, 2010. It 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 home to Hemorrhage, a remake of Blood Gulch from Halo: Combat Evolved and with elements from Coagulation in Halo 2. It 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 "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 enclosed area is reminiscent of the Crypt from Sandbox and appears to be made of Forerunner alloys. The entrance to this area is located directly under the "pocket" on the side of the clif.

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, Lockout, and Sanctuary can be seen as well.
